11:40 broke 40 bucks in drills and time spent in order to save on buying a 40 dollar piece. Would totally do the same.

I am loving going through all the old "This Old Tony" videos, and catching up with where you came from as a machinist, knowing roughly how far you've come. It is going to be a sad day when I get through the rest of your library (I predict 1 week tops,) and have to wait for a new video.

The DI running in towards the slitting saw gave me quite a chuckle. Great vid!

if you turn chromoly again the best solution is to use, and I'm sure you as an engineer understand this term, "a metric assload" of coolant

Revisiting this vid, cause i need to make some ISO 30 holder as well Wow, like your brass-hammer-drawbar-wrench combo

Great job! Love the indicator bit at the end! Know know where to tune when I'm feeling blue and need a laugh, thanks so much for taking the time to put these videos together and adding that comic flare!

Your so hard on yourself. So far as i can tell, you're an incredible machinist! You should be proud.

my grandfather was a machinist for the L&N railroad here in Louisville. I like watching guys like you to learn about his job. fascinating! I always thought he was a mean old fart but I assume he had great talent. was a machinist for 40 plus years. thanks for your time and effort.

When we needed to "hack" a piece of custom tooling, we cut the taper, put it in the machine for which it was destined, and used tool holders on that machine to finish it. Concentricity was guaranteed (if you bolted down your tooling properly!)

Your videos are very entertaining. I work with metal cutting since I graduated in highschool twenty-five years ago and still love working with these machines. The Schaublin milling is a yet-to-be-true dream at least for me.

I like the parts with using a drill for the automatic feed...

Using tools to make tools ... I don't know why but watching it is absurdly captivating. Thanks for the videos!

Love this video. Also the overarm support, the tool post, these are my favorites. Your stuff on carbide is icing on the cake. Thanks again Tony!

The clamp from the V-block "Gave up the goast"... I love ur vids, so keep on with ur good explanations and work.

this is the kid of quality content that we need on youtube and TV. I hope you'll keep making interresting videos like this. An hello from France.

Thanks Tony for sharing this project! I've got an NMTB-30 Wells-Index that I need to make some holders for. This answers some of my discovery questions.... :)

Thanks for your videos, glad to see someone else making his own tools. My dad was making a really heavy-duty drill press using an automotive transmission, it was huge. Unfortunately he passed away back in 1996 before it was done. Family wanted the money and could not see letting me run it in his name. Now that it is 2020 I have a mini engraving machine not large only 300 * 180 * 45 mm it is a steep learning curve converting. AutoCAD drawings to CAM g-code

Hello there Tony from deep down across the Pond !!! Like the style of Your Videos. No long drawn out delayed Turning Cutting runs. Explanations given. Set up shown. Run executed. Job done. Cool. Keep 'em rolling And Thanks for showing and sharing. All the best aRM

Running out the cross-slide to prevent crashes is a good idea! Nice job on the tooling.

That's the best slitting saw I have seen ever much less shop made!! Great work, great video.

As always, amazing work and great humor.

awesome info.... thank you. love your channel and the work you do

Man, I wish I kept up metalwork and engineering. I also wish I had room and money for a machine shop. Making your own tools is the most satisfying thing I can think of

I love how you try to save every one time by speeding up stuff as small as moving something small around

I'll admit. I panicked a bit at the end.

Nice to see you break out the Pratt Burnerd KC15. I have one myself and I love it

I have truly enjoyed your videos and have learned a good bit from them. I enjoy your humor and the fact that you are not afraid to show when things go south. Regarding cold bluing of parts. I have done quite a bit of gun smithing and I learned a very simple trick to make cold bluing more effective. Try warming the part up a bit above room temperature. Not enough to effect the grain structure, just enough to make the solution bite deeper. You are spot on about the cleanliness though. Cold bluing solutions are so touchy. Your work looks great. Stay safe and have fun.

Hi Tony, i work chrome-moly steels alot for my work mostly 4140. to get it to chip well you need a pretty aggresive feed 0.2-0.3mm/rev with that feed and a decent chipbreaker it should come off nicely. even taking inly a few mms of the diameter.

Great vid Tony. I use one of those tapping heads, they can be finicky to set up the correct clutch pressure but generally I give them a solid 7

Great video. Always excited to see your content on my feed! Keep it up brother

Wonderful detail explanation and display thank you sir you are a gentlemen and a scholar.

I cant believe you are howling about the cold blue process. You are getting great results for cold blue.

HUGE insperation, I just made two ISO 30 end mill holders.... 20mm and 25mm inspried by your video.I didn't have a collet big enough to fit the outside OD of the business end of the tool holder so I had to turn an arbor, first 25mm, then took it down to 20mm. I nice snugg fit and set scerws for secruring. they ran true and worked out well with light cuts... 1mm roughing, 0.25 final cuts.Thanks for the ver very cool videos that beginners, homeshop guys and pros can enjoy

Re-watching everything from ToT for 2020 Christmas present...thank god I have a stable job

your videos are really great. And fun, that subtile humor of yours is just so good.

Ave used a carbide die grinder bit to cut out a broken tap, that may work for that drill bit. Your videos are really helpful thanks for putting in the effort.

Nice work Tony!👍

As someone in the comments said below, for this type of material a lot of coolant helps and if you want it to chip reduce the rpm..you will find a sweetspot where it chips nicely..i use this material a lot making half shafts for vintage cars..its an excellent choice for your application.

Nice job Tony. Enjoyed, thanks for sharing.

Love this stuff! That's old Tony!

Lathe can smell fear...😂😂😂😂🙀👨🏻‍🔧😜. Tony, I’m not watching tv anymore thanks to you!!! Your hilarious 😆!

Just about hurt myself laughing at the end, there. Thanks for the day-brightener!

Awesome video. I learned a lot.

I've worked with 50CrMo4 a couple of times, and the experience I've had with it, on the lathe that I usually use (can't remember the model), is that to get the chips to break, I have to take very deep cuts and just 'force' the tool against the material. 2mm depth of cuts always seem to make those irritating meals of spaghetti-metal, but as soon as I change it to 3+mm it starts to break nicely at a feedrate of 0.2-0.3mm/rpm and letting my insert get a longer life, though I don't know whether your lathe would have the power to do that :) As for coolant, I use a lot of it when working with this material (but as a trainee-machinist I'm not sure whether I should do that, or just wait and let it cool off on it's own like I usually do with regular steel-types). You are right though, it gets hot as hell :P Greetings from Denmark :b

for milling slots you could have threaded a bolt in the end of part and indicated off of the flats.

Great video, well produced as always!

Great job, Tony! I really like that you're making the tools yourself rather than buying them all.Sincerely,Tom Z

I screamed loudly at that slitting saw vs the dial indicator. I’ll send you the invoice for the pants cleaner, tony.

The Saw Blade Wobbling a little bit. The Joke was so Funny

Thanks for great video. Btw Behind the lath chuck there is a mores tapper throat to match tapered surfaces with machine surfaces.

Probably a bit late now but I was wondering if you could just press that broken drill bit out? I'm sure it's well and truly jammed in there but I'd be surprised if it was 25 tons of jammed in.

Your videos are the best love to do something like that some day

I make a fair bit of my own taper tooling. My mill has a 30INT horizontal spindle, but I converted the vertical to a pneumatic drawbar and that is BT30. (The tapers are, conveniently, identical). My approach has been to make a sleeve for the spindle taper that accepts the 7/24 taper of either tooling. I first made a tapered bush to match the lathe spindle internal taper . (it is almost, but not quite MT4.5, but conveniently self-locking) then in-situ bored that to take my mill tooling tapers. (and marked the point adjacent to peg 1 of the D1-4. You could reference to the key of the L0 on the Student.) That means I can cut the taper as the first op and then pull the tooling back into the lathe spindle with a drawbar and be reasonably confident that it will run true in use.

Great VIDEO!!!!

Many Thanks Tony. Great video and editing. Like the PIP inset and how you blasted through the repetitive stuff. Learn a lot from this one, mainly about not being afraid to cut taper tooling. Just worked my first 4140 and was please with the result on my wanna be peanut...That Moly looked like hot cream cheese coming off but was pretty recognizable as medusa razor wire with a bit of color. ~¿@ Your saw was amazingly straight so your tapers and concentricity must have been on the money! Beauty in metal work! Thanks for the hoot at the end. Great builds and Edutainment!! ~PJ

Another great video, Thanks Tony!

Dang it TOT! I hate the way everything in machining is so easy when you do it. Thanks master from Swe, I'm learnings so mutch from your vids.

i wish you made 1 vid a day.... i love watching your shit

Hey Tony, For stuff like flipping those for notching in the mill, I have seen guys that make exhaust collectors with multiple pie cuts use those magnetic dial angle finders when cutting pipe. Basically take some putty, glob it on the back of the dial then shove it on the end of the thing you wanna rotate, un clamp, spin, dial in to +/- a degree. You might even be able to use one of those magnetic digital angle finders (don't know if they work up side down).

very informative and entertaining video. Thank you. I like the look of your Rohm mill vice. Your video of the vertex 4" import vice gave me the confidence to buy one, how about a compare and contrast video of the two vices?

Know whats really fun with Chrome moly, contouring a 30" bbl between centers on a lathe :) The chatter and vibration is insane.

Great sense of humor. You get right to the point. None of the typical "Welcome to blah....blah...today we are going to...blah...but first I have 57 things I want to .....blah....." click, next video. I actually watched the whole thing and subscribed. Nice work on both the tool and the video!

Great video again! I admire your can do it attitude and humour. Please keep up the good work. Currently making a fixed gantry CNC inspired by your build. Would like to see more on the gantry and any modifications you would make to it, now you had some time to get to know each other....

i cut a fair amount of tapers and have never considered using a drill motor to power the compound, that's genius!!!!!

nice power feed attachment. i now have another use for my makita drill.

great job and talent

Nice, free tinsel for Christmas decoration!

Great tooling build enjoyed the video thanks

Love to watch your progres

Good one! I am just about to turn a bit more Morsetapertooling - You got me motivated ;)

Hey, TOT, I'm kind of surprised that you don't have a spark eroder for broken taps, bolts, and drill bits. They sell them fairly inexpensively through several companies, or there are plans for them online.

Very cool, Nice job my man.

great video, I'm always amazed at how much patience you have. this work is incredibly tedious, but rewarding and fun. The best part is watching your process for measuring and setting things up to get really precise parts. Amazing work.

always amazing

Nice work Tony!

Very impressive work mate,inspiring. I made some tooling myself in 30 taper for my Elliott Milmor Super 16. I got around the concentricity issue by making a 30 taper tool holder for the spindle of my lathe. Was quite a lot of work but means I can guarantee concentric tooling every time. I made a draw bar to suit and it works well. As an asides it also means I can use my 30 taper tooling in my lathe should I want to do some milling or boring in the lathe. Really appreciate you videos mate.

About 40 or 50 years ago I used to work in the Bath Iron Works and they used to blow out broken taps with a gouger

Rofl, that end bit with the indicator on the saw blade edge checking "run out".

amazing job wow

Also Tony please maybe do a little episode about these milling inserts one of these days!

Nice wood shelf.

great stuff tony!

Holy moly as a new this old tony sub I never knew this old tony made old videos as well as new videos. He really is old.

I like the sped up video --- reminds me of the demo vids you see for all the chintzy CNC equipment heh

Hi! This is the year 2020 calling (not a good year btw) - and the end of the video LITERALLY made my heart jump. Thanks 2016!

I had thought of machining the taper in the lathe an bring the business end to size/spec already installed in the mill. (Just thinking outside the box) But i also dont know, if the mill can handle these kind of cuttingloads... Best regards

17:56 haha that drill motor idea is cool. now i remember i had a similar idea to use a drill for my chinese Mill-press on the X-axis

I used diamond coated dremile bits and tile drill bits to remove broken taps from holes (usually stainless steel causes taps to bind and break).

Great video, good job, and fun to view...we don´t see that often in YT land...

Like CH3 collets for my Cincinnati 1B Toolmaster knee mill, circa 1963, only place i could find them still made are in Elmira, NY. FOR $190/ea!!!!!!! Luckily, the free mill came with a 5/8" one and i was smart enough to just buy a ER30 holder with a 5/8" shank.

i like your sense of humour.

Very nice. Bummer about that drill bit. Maybe time for the home brew EDM project? With a second drawbar, you can also make use of NMTB 30 taper tooling that is more common. I've done some of the same but to get the tool bore spot on, I did the finish cut right in the mill with a boring bar clamped in the vise.

Good job. That's prolly the least runout I've seen on a slitting saw holder

Eyeball it! EYEBALL it he says! Heretic! That they all came out pretty much perfect and fully functional means NOTHING! ;) Interesting and entertaining as always, Mr. Tony.

very helpful as always!

Great job !!!

The finish on Tony's lathe never fails to shock me. My lathe needs some tuning up, or something...

very cool. adapt and overcome at its best

You are like the dad we never had growing up. I mean, I have a mechanically inclined dad who taught me a few things, but he is no where near as knowledgeable, precise or polite as you.

Great job!
