Adam, chip clearance is the problem. You've got a blade with a section of teeth that never leave the material because the material is wider than the stroke of the saw. So you've got chips trapped in those teeth holding the blade up and keeping it from digging in all the way on each stroke. Which is why horizontal bandsaws replaced electric hacksaws.

Such great information! Two comments: 1- Your saw is running in reverse. There is an arrow on the large gear that indicates the direction of rotation. This is also why the screw holding it in place is left hand threaded, so that it doesn't come un-screwed while the saw is running. 2- Your ghost marks on the cut face are an artifact of the saw blade tooth spacing, dependent upon the spacing between opposite set teeth.

Releasing the bolt & dropping the motor on the floor killed me 😂. Thanks for being Human Adam.

Am I the only one bothered by the drive wheel spinning contrary to the arrow on it? This reminds me of working with my dad on tools like this. Good stuff.

My day is made, just sat down at my desk and popped open youtube to see an over-hour long video of Adam building something funky 😄

I’ve got this same saw, and did a restoration video on it, so it makes me very happy to think that Adam might have watched my video and took notes. 😊 I’m going to agree with everyone else who is saying you’re running it backwards. (It even has an arrow on the crank wheel. It should be cutting on the pull stroke (pulling against the fixed jaw of the vise) and lifting up on the push stroke. Some of these (including mine) and auto-shut offs. It wouldn’t be too hard to add one, and it’s a super handy feature to have.

Love how raw these videos are… you show your mistakes and “happy little accidents”. Makes me feel more human for my mistakes when i tinker.

Did that opening shot make anyone else think of John Henry competing against a machine? 😂

"I've needed something like this", goes through my head every time a see a new tool.

Adam was a complete menace for about 10 minutes of this

I came to the channel late, but Adam you know to use a V block to improve clamp force and stability on round stock, you even made a curved block of wood, then immediately ignored that you needed one on the clamps and c-clamps. Doh! As someone else suggested a chain clamp would be a wonderful upgrade and also a micro switch & relay auto-shutoff when the unit makes it through the stock. Bore those crank rods out and add ball bearings, add some compressed air to blow air at the side of the exiting blade teeth to discharge chips, and a gravity oil feed for blade lubricant. Overall this was a joy to watch. And My Dad brought me home broken drills, saws, othwr tools and coffee makers to take apart when i was probably 7-10, i loved learning how things worked. Enjoyed your stories. Well done

You know why I love your videos so much? It's because most of the time this is pretty much exactly how things would play out if I was making the thing you make and thank you for that, as I am unable for a very long list of reasons to bring myself to make things so as the saying goes "I live vicariously through you". Cheers and keep dropping and breaking stuff, losing tools and making mistakes, this is the reality of making!

I absolutely love seeing Adam (and other makers we hold in high regard) make the same mistakes that I / we as makers all make. Its one of the great bonds between all of us!

It has been 3 months... ... since I started cutting through this steel!

The toothed wheel is running backyards. Look at the arrow indicating direction of rotation. This can very well hamper it's efficacy. A.i. less torque when cutting on the pull.

35:00 After spending considerable time making a lovely big on/off switch, the machine jams up and Adam instinctively goes around the convenient OFF button he built and wrestles the belt/pulley drive with his hands and flips out the belt to stop the jam. This channel never fails to entertain. Love it.

Funny how we sound more like ours dads as we age. But I agree that sadly everything is made disposable now. Seeing an old peace like that, that is almost 60 years old, and still works great is a true testament!

I am not one to take someone like Adam to task. He is vastly more expert than I will ever be, and I DO NOT like making comments like this However, Adam cut several pieces and looked at the drive wheel repeatedly, There is a directional arrow on the drive wheel. The saw is running backwards, Unlike HAND HELD saws, this saw runs on the DRAW stroke. So the blade is in backwards, and the saw itself is running backwards. This is why he had so much trouble with the stock. I have used these TYPE machines before, I thought that the thing was running backwards (in the opposite direction Adams is) and was told this; "No Bob, the power of the stroke comes from the downward and to the back movement. When the saw runs that way the machines mechanical power is used to make it cut easier, instead of relying totally on the blades cutting action". A simple oversight Adam. Make the saw run the other way, and turn the blade around. You may just be pleasantly surprised. I could be wrong, but the arrow on the wheel says I'm not. ;-)

You are such a master. Adam. I love watching you fix stuff. I'm 56 and I pick up so many tips even if I will never own one of those. thx for sharing.

I know you've covered this on the channel before to some extent, but working on old bicycles is another avenue. Rebuilding a 60s Schwinn into a solid commuter bike was a big part of reawakening the nascent maker in me.

seeing adam clumsily use a screwdriver to pry out the machine when 2 days ago he showed off his teeny prybar is hilarious to me

A few months ago at my welding school our TCM-100 cutting machine stopped working. I pulled out our spare machine and it lasted only a few minutes. I was so grateful my boss let me go ahead and make one machine out of two. They are expensive but still a new tool that is user serviceable. At the end of the day having never even seen the inside of one of these I had a wonderful understanding of how they worked. I was luckily able to get us back up and running with one of our most critical pieces of equipment. Some companies still make good quality serviceable tools and I was extremely great full that day. And I got your same endorphin rush when it worked.

I really like the old time black and white montage and then getting to see Adam saw at the same time as the machine. Pretty cool.

Again, another dive into the constant pursuit of the ultimate one-man operated, general purpose fabrication and repair shop! ... and again, Adam seems to be tempting the law of gravity repeatedly. I must have yelled "look out" to my computer screen 3 times (without a response of course), which has made this one of the more nail-biting episodes I have watched recently. Thanks Adam, for once again making me jealous of your acquiring of yet another tool I could use but didn't even know existed!

first thing we ever did in metalwork at school at 11, used the ww2 era auto hacksaw in the metalwork shop to cut 3/4 inch square bar into cubes and add punch marks to make steel dice

Speaking of repairing cars, that little "loosen up dance" you did after sawing that chunk of steel by hand reminded me of all the periodic flopping around I did last night while dealing with a stuck-on Freightliner oil filter. The actual work wasn't as hard, I don't think, but the angles I had to work with - on the ground, trying to hammer screwdrivers into the filter to torque it off in the limited space afforded by the frame, while trying to keep an oil pan under it all to keep from making a mess in the customer's lot - were an ergonomic nightmare, making it a similarly difficult job. This is why tools were invented, to make these difficult tasks easier, and I'm glad you got one that'll make (most) of your metal sawing easier!

lawn mowers too. my brothers a mechanic and when he was younger and couldnt afford cars or car engines he borrowed second hand old lawn mowers off my uncles who in turn played with them when they were children. a really good way for my brother to familiarise himself with a basic engine. hes a very skilled and intuitive mechanic now

Hey Adam, thanks for the videos and sharing your stories :) One of my Volvo Engine Mounts moments was when I came back from holidays and my old laser printer had gone into a continuous power cycle loop. It was the weirdest thing. I could have gone out and bought another printer but I couldn't help take it apart and have a look. Found leaking caps on the power supply and fixed it with a $2 cap which allowed me to keep using it for another year. Moments like that are what keeps me in the work that I do. Unfortunately it only happens every few years now but I think it's got to do with the fact that my job is fixing problems every day. But sometimes, there are those golden moments 🙂 I've learnt so much breaking and taking things apart. Thanks for your inspiration and wise words!

This one may take several sittings to get through but i am here for it

I have found that motorcycles, even the advanced sports bikes, are still a very good platform for getting into mechanical systems. Repair manuals are somewhat easy to come by, and the space required to actually perform repairs is a lot less than what is needed for a car.

❤️ when Adam gets mad at tools cuz, 💯 been there

I have almost this exact saw, and I love it. It has almost zero utility to me, but I hold on to it anyway because it is just so cool. You are running it backwards; though I don't think it makes too much of a difference with a hacksaw blade but cutting on the upper stroke of the wheel may supply more downward force on the workpiece and make a more efficient cut.

For the old wire issue. It's gonna be oxidation (effectively rust) a good flush and some heat will sort it. For big cable get spot with the brush in the lid. And start with window open and a fan rather than after inhaling the forbidden smoke

I have an old 1940s Delta 14” bandsaw, i found it on craigslist for $60 in rough shape and talked to the guy selling it, there were other folks interested but nobody could give him a solid time to come get it. I said I could be there first thing tomorrow morning, he said it worked for him, and the next day im hauling it home. This bandsaw is the ur-bandsaw, the saw that all 14” bandsaws made since are made in emulation of. Consequently there are parts readily available for all the pieces I could conceivably have wear out, and I can work on it with just a wrench and a screwdriver. It has a backgear mechanism by which a lever can be flipped and a belt swapped to allow it to cut various metals as well as the standard fare of wood and other soft materials. Its my pride and joy. Theres one problem: the motor it came with was in awful shape, and its a 1/2 horsepower motor. I have a gorgeous, period correct 1 HP motor I would love to attach to get this beast running, but the motor shaft is 3/4” and the stepped pulley I have is only 1/2” and cant be bored out as its a relatively hollow white metal casting. I wish I could find either the original Delta pulley # 718 with a 3/4 bore, or find someone able to make a suitably sized pulley. It seems like a fairly simple project but I dont have a lathe. So thats the one piece of this puzzle thats holding me back and keeping me from being able to use this beauty of an old tool.

I really like the heatshrink solder connectors they make life so much easier.

Saw that acrylic shatter coming a mile away. You need to support the drill point as it exits, just clamp the work piece to another scrap and drill through both, can even use standard HSS bits unmodified.

Metal has stress. It changes shape as you relieve the stress with cuts. Drop a wedge in behind the blade on an insane cut like that. Watch some tree cutting videos for an example. August Hunicke would be my trusted go to. A riving knife, on a table saw, does the same thing. It also provides safety from the momentum involved, beyond binding on the blade.

You made a wonderful reflection about more basic tools..ole day autos and simpler tools..and what engineering knowledge you can gain by fixing those things. I do that a lot..mostly because I'm cheap but I learn so much. That hacksaw provides great lessons: 1. First you can learn about motions and how you can change its direction, speed, and effect by clever understanding of machines. 2. You can learn so many basic electrical concepts and learn how to measure ac and dc currents and how to deal with wiring. 3. Of course you can learn about electric motors and how to use them. The repulsion start motor is somewhat and oldie way of getting an extra oof to start a heavy thing to start rotating. They actually have greater torque than the more familiar capacitor start motors. 4. I don't know if you knew that hack saw had a repulsion start motor but by adjusting thid lever with that pointet you made an acetate vover for changes the rotation direction. I just learned about these strange things!

hard not to love Mr. Adam Savage

I've only been watching Adam's channel for about 6 months. One thing that surprises me is he's" very bull to the gate" in the way he works! He has all the time in the world but he rushes like he's on a tight deadline! I completely restored a 1963 Shima power hacksaw a couple of years ago. I have a sandblasting cabinet so I blasted it. One thing about cast iron is that it comes up awesome out of the sand blaster. One of the casting legs is a coolant reservoir that I got going again. It has an 18 inch blade! The thing is lethal and does not differentiate between metal or flesh!

Nice, Adam does Hand Tool Rescue. Cannot wait.

Its such a joy to be on your need-out jounry with you. You're an inspiration to makers everywhere.

20:13 I love this story of repairing your own car, gonna have to replace my compressor in my car, hearing this is lovely inspiration for getting that project done.

As for the Old Solder and new solder. A very broad overview without going into material properties. The lead content and impurities in the solder were not made the same as todays products. With corosion on the wire and solder over the years and different material properties the solder is needing a higher temperature to melt. The easiest solution I have found over the years is to add some fresh Rosin to the old solder & wire. Then put some fresh solder on your iron. With the molten solder on the extra hot iron, apply the tip of the iron to the freshly rosinned old solder. The heat will penitrate and the rosin will help clean the old solder and wire. With the mix of the two solders (old and new), pre tin the new wire then apply to the old wire woth heat. Keep the hot iron on just a bit longer then normal. Dont forget to use heat sinks on the old and new wires to prevent to insulation or other components from getting damaged.

From 7:06 to 7:25 ... that HUMmmMMmMMmMMMmMM of that motor is music to my ears. Sounds so smooth!!!

Adam, make your bushing! In 2009, I made a concentric bushing to fix the threading lever of the lath, on the lath! Still proud of that shot!

Not sure if it has it, but you could add an auto off switch; a mains microswitch with a leaf set just at the point the saw finishes going through the material, you could even make it ring a little bell... Set it up on the right hand side.. if you are worried about it sticking, I think you can get over current cut outs, so the safety switch will trigger before things get toasty.

I’m sure you’ve thought of it, but a couple of possible additions. Fabricating a handle that attaches to the fixed portion of the arm will allow you to gently lower the blade onto the material without trying to hang onto the reciprocating section; same for raising it up again. Though it would be a bit more work, I think of my portable bandsaw having a switch positioned so that the saw going completely through the work makes contact and shuts off the saw. Handy if you’re letting the saw do its long work while you are otherwise engaged hither and yon in the shop.

A craftsman saw from the 50s? I bet it was made in USA! Thanks for all you do!

15:52 “everything that can go wrong will go wrong” XD

Loving this long-form content. Watching you work and talk to yourself is so chill when I'm working. Wayching you work on the motor was very cool. Please make more like this.

If I'm not mistaken, that's a variable speed motor. The adjustment lever lets you set the speed to your liking, and probably even lets you run it in reverse.

Adam, having observed you operate this machine during the setting phase, may I suggest moving the start/stop buttons towards the front of the machine for ease of use, and possibly adding a foot operated em stop.

You are an inspiration, Adam. I love your content. It is always educational, and the world needs more of it.

Fixing old mopeds has given me the same feel of successes that you discribe. The level of satisfaction I get from starting up an old engine that, before I fixed it, was in boxes, is just fenomenal! And getting to apply that learning into engineering is really a great feeling aswell.

FYI when drilling acrylic you have to keep the bit cool, spray the work if you can and if you need to keep water stains to a minimum keep a cup of water near and dip the bit. The Acrylic heats up and melts around your bit causing it to crack when it cools down. Run the low speed of the drill as well.

That harmonic pattern in the cut. Have your read " Farwell to the master"? short scifi story about that.

Take it from one maker of a similar disposition to another -- putting crimped ferrules on the ends of stranded wire would make you happier than you probably think. It's not functionally necessary, but it feels so proper and the tool you use is so satisfying.

Love your chat on car repairs. I can definitely resonate. I started my repair journey on an 86 Honda Civic that my dad had for 15 years when he gave it to me.

Used to bring an auto hacksaw on service calls where wed have to cut jack shafts to fit out of schedule 40 aluminim..set and forget while we worked on other parts.

So, you're just not gonna address the fact the machine is running in the wrong direction? Look at the arrow on the large geared wheel, Adam! It's rotating in the wrong direction!

I love that the stand was mounted to an old cabinet door. I feel I could tell you a lot about the man who owned this based on that fact alone.

I love getting used tools, especially stationary ones like this, theres always homemade repairs that when you look at it you can see their train of thought as they made it

Had one of these years ago. Bought a good horizontal band saw and never looked back. Faster and the blades last longer. There is a reason they don’t make these anymore. That said, I am a lover of old machinery and the cool factor is there. I sold mine though and don’t regret it.

Join us for this week's episode of "Watching Adam Work Gives Me a Giant Anxiety Attack" lol.. 😂... his ADD and my OCD are very incompatible 😂. Usually I'm freaking out about adjusting the camera 50 times, while changing topics mid story 50 times.... but these repair/build type videos add in the bonus anxiety of watching him rush way too much, way too many times, on way too many tasks.... Don't get me wrong, this is my favorite channel ❤but my brain explodes...

It's so true how much of a good feeling it is to fix your own car, I always have and my daughter's always watched me so when it was time to get her car she did her own breaks shocks changed all the light bulbs which aren't that easy in the newer cars, and change the oil all basic stuff you can do it home and she was so proud of herself telling all her friends

That saw sound is a soothing background noise :D

I know the feeling Adam talks about when tinkering with stuff and taking them apart, its such an interesting feeling of discovery and wonder.

This asmr is oddly satisfying. Never imagined that from Mythbusters.

Thank you for sharing such a wonderful gadget.

This video goes great with my addiction to Hand Tool Rescue

so satisfying when you fix an old piece of machinery like that

#mymechanics is my favorite restoration channel, with #TySyTube and #HandtoolRescue tied for a close second. I once repaired a harmonic balancer that had wandered off it's bushing by pressing it back into place with my neighbors 16-ton pipe-bending press. It shouldn't have worked, but, miraculously, it DID! It was an endorphin-releasing experience for me. I won't recount the experience of replacing the thermostat (and, ultimately, thermostat housing) on the same car (a '99 Chevy Malibu 6-cylinder), but I will say it was the exact OPPOSITE experience. Also replaced the engine mounts, which WAS fun! All this to say, I relate and agree.

tool marks that tell the story of how something was made are always so interesting to study, great for a challenge coin, perfect for an Adam Savage challenge coin

Hah, loved that intro! Well done, editor Self! 👏

Adam! I'm at 56:56 and can no longer hold my tongue (keyboard). Rig up a chain wrench to clamp your workpiece. If done properly, it will conform to any shape and apply force toward both the back vertical jaw and the horizontal base of the machine. Also, since you are doing such great improvements to the machine, think about rigging up a slow drip cutting oil dispenser for the blade. If you use tap magic, water soluble cutting oil, etc., you will drastically speed up your cutting times, improve kerf accuracy, reduce drift, and extend the life of your blades. 😉 Beware that a tool like that does not stop when you press the stop button! And keep your hands away from that workpiece whenever it's reciprocating!!! I winced every time you did it.

Wow, that is a treasure find. Adam Savage, the man, the tools, the legend.

I had no idea automatic hacksaws were a thing! Awesome!

Not just fuel or fire, an important third leg in the equation is air. Keep up the videos Adam, it’s always a pleasure to see what your diving into next!

This went from simply cleaning up and repairing an old tool to epic mod build real fast!

I still cant believe Adam hasn't blown himself up on video yet, as someone who has shocked their selves more times than i can count Adam and electrical makes me think of myself before becoming a electrician 😂

I gotta tell you, my heart skipped a beat. As that motor was rolling off your bench, I dove to catch it. Much to the surprise of my cat, who was laying under my tv.

This machine was probably the precursor to the horizontal bandsaw. I love how the old machines were made to last.

So glad to see this wonderful little machine have its day in the spotlight. I have one as well and set it up with an auto-shut off. The shut off switch is mounted so the bottom of the cutting arm bumps it on the backstroke after the arm has dropped from the cut. If that makes sense. The on/off is set up on a simple relay circuit.

I love the subtle "hop" it does on the backswing to clear the teeth and then push them back down on the forward stroke! amazing tech

Love watching you take things apart to set them right again! Watching you trying to cut that round stock around an hour in reminded me of something. They do make C-clamps with notches cut into the.. feet? of the clamp for gripping pipes and whatnot.

There is something very calming about watching these types of videos. I really enjoy it.

the intro = shop madness

You need a wedge under the front of the big old round bar!

Thank you for answering the main question I had before clicking. Which was "Why would you have any need for that with all the other tools you have, what function can it serve better" Essentially, it's automation, and I can completely get that being able to set this working while you're 3d printing another part and making something yourself can add something to the workflow.

Mine is 100 years old, weights 400 lbs and cuts like BUTTER. Hands down my favorite tool.

Y'know I could watch Adam take stuff apart and grease things all day long ... It's like therapy :)

Always entertaining and sometimes Savage is as Savage does....just like the rest of us.

I had an '89 F250 as my first car and absolutely agree with you that cars are the best way to get that practice in. Thing was an absolute hunk of junk but being able to buy a part and repair something for a couple bucks instead of hundreds at the shop teaches you incredible lifelong lessons and builds that confidence. Also taught me to always do a thorough inspection before buying a car 🤣

Regarding taking things apart, when I was 12 I took apart my dads old portable typewriter, literally down to the rods and pins stage... I then put it all back together and it worked. Once my dad saw me do that he bought me a big technical Lego kit for Xmas and the rest is history.

You filmed this on my wedding anniversary day. Cheers

A very important part of learning about mechanical things for me is bicycles! So simple yet so much to learn from.

Oh my dear sweet baby Jesus, what a sight to behold. Adam Savage has outdone himself.

I wish and hope to one day have that confidence of taking something like that apart and being able to put it together again...I am getting there..and it is because of Tested...it is definitely a journey
