Dear Max, fresh to watching your show and two things I have noticed. You work through more tools in depth than anyone else I have seen on YT. I like the fact that you realise that you won’t be seeing me but I will see you. Nobody on entire YT domain has gotten that right before you. One thing with the low arm for your slotting head. You can get a spacer to lift up your working body about 400mm. It will be a pain to install but in the end will give you plenty of extra height on both sides of the Bridgeport.

Nothing to that job eh Max? Just three setups to modify the mounting bracket, and a total rebuild of the slotting head to do a one of part! 😂 Absolutely love your videos and always learn something from them.

G'day Max, 5.00am coffee and start the day watching this, perfect, always enjoy your videos, and learn heaps too my mate, have a great one, thanks for sharing, and best wishes to you and yours

This was a great series, Max! I really enjoyed it and learned a lot.

Enjoying the video capture of chip product form. Some very nice demonstration of precision and how to think about tool form and motion. Nice to see the shop layout and working process Max. Thanks for having me along. M.

Very interesting stuff, I can see where a slotting head would suit a WW2 production environment.

The slotting head lives and delivers.. Nice conclusion to the cam socket limit spring holder screw in thingy. Great series 👍👍 Cheers....

Nice camera work capturing the almost impossible, thanks.

very good video friend Max

Great insight into slotting Max, lot of work to get there, but its ready now 👍. Thanks for sharing

Hi Max, our forefathers were pretty good machinists, in this case it might have been a Woman slotting the feature. Seen wartime documentaries with Woman using Shapers. A narrower tool insert will reduce the tool deflection but increase the time to manufacture but you achieved the desired result, good job.

Complicated. . You did a great job. . fantastic showing us the difficulties. Cheers.

Great job Max, a bit challenging, but not as challenging as getting the slotting head sorted out after being butchered by the last guy!

Love Monday nights in England. I get to watch one of the best engineers on Yt, I don't care how long the videos are, This 20 min YT logarithm is bullshit, in my opinion, 20 mins is too short. I am pleased you take no notice of this

You'd think there would be a lot simpler way they would have built that, like spot weld a piece inside there. Great work you did there. Cheers

G'day Max , Interesting watching you use a shaper to work on a slotter. Cheers. Both the slow and fast motion vidios were great.

That turned out well Max. It is a lot of finicky work to make some of these parts but it is satisfying when they turn out. A while ago someone on Practical Machinist commented that the rise of carbide insert facemills spelled the end of the shaper. Watching this I tend to agree. Olga would have machined the three edges off that bracket in three passes using the horizontal spindle. Before I got my horizontal mill I used to machine the edges of flame cut parts with my shaper (much lighter than yours). I was amazed at how well the HSS tools hold up when they are used in a shaper. I'm not sure why but they seem to take way more abuse in a shaper than they will in a lathe. Ken

Enjoyed the discussion/build…success…nice job

Lovely job there Max. If I had been making this and not having any means of slotting as you have, I think I would have made a seperate insert and silver soldered it into the bore.

Hi Max, good video. Having never touched a Shaper I’m enjoying the tutorial. But having some time on a slotter watching you gave me a smile. Once had to join a pump motor to a generator . Made an adapter with an internal spline one end to slotted keyed socket other end. Five minute job…. Obviously.

Thanks Max, for the "trifecta". Interesting to follow your thought process through a complicated and thorough process. You made it entertaining to say the least. The shop looks great. Cheers.

Max. Challenging job nicely done, I would have silver soldered a half of a tube instead 🤦🏼‍♂️🤣👍🏴󠁧󠁢󠁳󠁣󠁴󠁿

Another awesome video Max, from kiwi land

Awesome video Max on the workings of the slotting head! I was very interested in the engineering and operation of slotting head. Cheers from Minnesota!

The slo mo shots are EXCELLENT! Really enjoyed seeing those chips curl and fly. Brilliant stuff as usual.

This is such a good series! Enjoyed EVERY SEC of it! Greg

Spot on Max, bloody good job that!

That sure did turn out great.

Good tip about talking up the backlash on the shaper downfeed thanks.

That a nice bit of kit that Max. Wish I had one. Cheers

Very nice Max. The slow-mo shouts are awesome.

Hey Max, I was thinking, there is a KZfaqr named Paul Brodie, a pretty famous Canadian bike builder (he does awesome silver solder work!) and he uses what he calls a spiral roll to polish his angled frame joints, and it works a treat in the hard to reach places. It's tapered and rolled sandpaper (coned shape) about 2 inches or so long (maybe a tad longer) and he uses them in a pneumatic rotary tool (a drill would work well too, a high rpm one is better I imagine), and they have a shank on them to chuck down on. They polish really well, and can get into places that are hard to reach. He uses them to polish his welded joints on the frames, mostly his silver solder work, but also his tig welds. The diameter looks like about an inch or so on the big end, and around 1\4 to 3\8 on the small end. Not sure where he gets them, probably McMaster Carr, but I can find out if your interested. I was thinking that it would have worked well to get the finish you were looking for on the part you just slotted.

Gday Max, the slotting head works a treat, I’d say that’s the end of slotting by hand now, great job mate, cheers

The digital angle gauges are pretty fantastic, we cut gears with WW2 era machines, you set hob lead angle with a vernier that gets no better then 10 minutes of angle, and bevel gears with similar accuracy. between dirt, poor lighting and less than stellar vision and inevitable paralax error its amazing they work as well as they do, but they do.

Max, it looks and sounds like you ministration to the slotting head have born sweet fruit. She sounds smooth and bobs up and down real nice, kudos on a job well done.

Max, I always get something out of your videos. That was very impressive. Jeff-North Central Illinois-USA

Great job max not easy to copy that part for sure👍👍👍

good end result max ! cheers ben

Always learning something on your videos. Thanks for your time and skills!

Excellent video. Thanks.

Great work old mate , regards from Mt Hawthorn.

Great job Max. Really enjoyed the series. Thanks

Another piece of shop equipment brought back to life so you can finish off these 'tractor' parts. I'm guessing that tractor could have been a WW2 era Fordson model 2LB ;) Keep going like this Max, and would could see more machinery resurrection in your new shop :)

Yeah I've had to do similar things with the top and side rake to get my E head cutting. Agree with using the largest diameter tool shank you can fit in the bore, with short cutter projection and honed edges. You did get it cutting well though. I mostly do internal keyways with mine.

G' Day MAX Great Video Sir . Cheers From Oklahoma

Superb work Max 👌 Cheers Chris

In the shops I worked in we used to grind thru the flame cut edge if we had to drill thru it or machine it with an offhand grinder. Enjoy your advanced setups and solutions to very interesting projects Max.

Thanks Max, this video is really packed with interesting stuff. 👍 Despite having visited hundreds of shops and factories over a lifetime, I don’t think I ever chanced to spy a slotting head in operation. Certainly I never used one myself (yet). How nice to see a big Starrett indicator on the job in Oz! I live near the Starrett factory, so naturally I’m a fan. The company logo looks nice, doesn’t it? You probably know that a gear sector is a key ingredient in those indicators; it’s fascinating to watch those being made. They use high speed CNC shapers to form the tiny, precise gear teeth. The shapers stroke so quickly the motion is just a blur.

interesting as always - thank you 👍 my original Bridgeport head bracket is much more "dinky" and is a fork with plate on top and bottom, rather than just single plate like yours be interesting to see how yours will stand up in use just "hanging on the bolt nut" ? look forward to more videos about slotting head tools

Good one Max. 👍

Great video. Reinforces the saying that no one ever made money with a shaper 😂

I am not inclined to do it but if I were to do a stress analysis of the connection between the mounting bracket and the mounting end of the machine we would be able to see if there would be much difference if the bracket were mounted on the top. Having experience in this type of thing I am thinking it wouldn't make much difference in the overall stiffness of the set up. Stiffness is the resistance to deformation. Wish there were more hours in a day. This would be an interesting and fun thing to look into. Thank you for a very well done video

Hi Max great fimtografie there solved the problem and completed the part also got the new old machine thingie up and going nice to watch glad you seeded up the job for us as that would have tested the limitations of my Medication for sure Always the teacher and I always the eager Student for sure thanks Max for taking the time to show the build and the how to use Just one thing with the small edge on start of slotting could that come down to the mount you say your going to make more better ? Nice job Cheers

Hi Max looks like the first job on the slotting head tuned out very good. Needs a little tweaking as is the case most of the time. Cheers

G'day Max. Excellent job on the Slotting Head Assembly which worked out very well. You had a good Master Class in setting up & operating the the Rotary Head coupled with the Slotting Jig. Overall it was a Great Job well done, My question is, could the cutting tool have been a fraction wider & slightly rounded for a quicker finish ?

Wow. That is a process getting here. Nice work Max

That looks like a win to me. It was nice to see the final assembly.

Good work Max. I think that you are definitely ready to start slotting. Everything is coming together nicely. 👍👍 Cheers 👍👍.

You'll be making keyways like nobody's buisiness Max. Interesting job and exellent solutions mate, well done, it was very nice to watch, cheers.

Fantastic Max, enjoy watching and learning from an experienced machinist.

That is a great project and useful too. I know where a slotting head is, maybe I can get one.

good job 👍

Maybe when you make your adjustable bracket for the slotting head, you could include a cross slide with gib & lead screw & nut so that you have longer upwards and downwards travel to give you more setup options. 😉👍

A good job Max. And a nice slotting head to.

good work max

Great video Max, Mike from Texas 👍

Great video mate

Hi Max. Good stuff! How about using a broach guide to stiffen your tool? No pun intended!

watching the Shaper go back and forth, back and forth ... and the Slotter go in and out, in and out = was very pleasing ? 😅

Decent result Max. I never got to use one of these slotter attachments on bridgeport or like the mills. Ive only used the purpose built ones, the monsters and the easy to operate ones. The huge brown & sharp slotter I used had no clapper on it, ridgity was the key to deal with deflection. We used trefolex, and waited till tool pressure cleared last cut before adding another.

Thx. for the vid. Part turned out Great.

On a shaper you can make whatever you want. Even if it's vertical :) What could maybe help to control the tool flex is to cut the whole surface with the slotting head. Or on the shaper... Just an idea.

Well done Max, still think a half cup welded in place would have been quicker but fully get you wanted to make it as original. I don't have a sloter so have to find ways to make things

When that shaper catches high gear, it really takes off, I tell you what.

I've never had any luck with the stock BP clapper, never a problem just locking it solid.

Thanks for the show Max 🍻

Pour yourself a well deserved ale sir. A great finish

Nice one !!

Hi Max, I wouldn't bother with what you are calling the nod on your new bracket. If you turn the tool holder round 90 degs you can set the head over to allow you to cut a keyway in a tapered bore. ( at least that's what I do now). Works a treat. Best wishes, Mal.

👍nice job

Great job Max. I always look forward to your videos. Question- what is all the orange silicone crap on your rotary table. That appears to be a South Bend from Grizzly tools, I have been looking for a table and I like that there's have 6 T-slots and I think it's made in Taiwan. But that orange crap got me curious as to what the hell is going on with that, could you tell me what you think of it. Also do you all have Grizzly tools over there? I thought they were just in the US. Cheers Max! Keep up the great video's we appreciate your hard work! 👍

Nice to see the slotting head working. Wondered if it would help to mill a small flat on the side of the tool shank, before sharpening it, something to be able to repeat the orientation of the tool. Also, watching how you ended up doing this, thought if the tool could be rotated through a small angle in the sharpening fixture, could grind the 2 sides of the tool to the angle corresponding to the width of the tip, then it could be used for both ends of the gap.. icing on the cake if there was a simple way to grind the right radius on the too between the 2 sides (center may not corresond with the center of the shank?), maybe could grind two facets perpendicular to the sides of the tool & free-hand the radius between these? Also, as much as we love shapers, that looked like a great job for a bandsaw (unless risking the blade with the hard surface..).. Great video!

Thanks for the video.

great video thanks for it

All I got out of the video is a desire to buy a slotter. I probably wouldn't use one but I want one!

very nice. You mentioned using a shaper and you are right it is possible.

Now we're ready to get this mounted to the machine My thoughts It's about time I am eager to see the damn thing working Anyone else

I thought the mount would be upside down to the way it’s installed, with the side support brackets on the bottom so that the head could be swiveled around more. Unless you think that would make the clearance too small.

Thank you Max!

Difficult job....nice work !!!

Why worry about nut sizes ? I just have two adjustable wrenches, one imperial, one metric !

Good video thanks

Pretty neat process

Maybe turn the tool 180 degrees in the clapper so the tool pressure tends to close the clapper rather than tend to open it? I do this on my shaper when cutting keyways.

@ 22:28 Mate, sandwich the plates...??? Have two of the buggers, the top one welded, bottom one...bolted..??? or not. Give you the strength you need.??? 😮😊

I suspect the clapper on a Bridgport type slotter is only going to work with very short tooling in the vertical orientation or tooling in the horizontal location in the tool block, the geometry isn't advantageous enough with long vertical tooling used to get into smaller diameter bores, the clapper pivot axis is too close to cut line of the tool so the tool pressure pushing the tool off is enough to overcome the cutting force trying to pull the tool in, the longer the tool the worse it gets. You can get the same issues on a horizontal shaper if you use a very long internal cutting tool mounted in place of the standard lantern tool holder, which is why the manual for such should state the distance between the tool and clapper box face, on my Elliott 18" it is 7" to the rear edge of the tool, but you do always have gravity on you side on a horizontal as well.

Hi Grant! Do you think that maybe the original piece was slotted from the top edge, rather than down at the lower point? Ron...

👍

I would hate to price that job, man hours on the job, very interesting project though

I wonder if a radius on the cutting edge for the final pass would help...
