This Polygon lathe cutter mechanism is a game changer

In many cases, a processed piece on the lathe needs to have some shapes in some parts of it not cylindrical shapes that a conventional lathe cannot create. These shapes can be square, hexagons and generally polygons.

Invented by an Ipswich UK engineer in the 1960's who took the idea to Colchester Lathes. Was told not interested but they then went on to make machinery to produce polygons of pretty much as many faces as you wanted. Colchester Lathes made a lot of money out of it and the engineer got nothing.

[@lubomirkompis9441]

What was the guys name?

[@1992jamo]

I had not heard this. What was the chap's name?

[@charliepearce8767]

Typical.

[@mrfarts5176]

It's because the ownership at that company was gay.

You discovered the reasoning behind the patent system.

[@Gin-toki]

The demonstration with the markers was rather neat.

[@jamesrogers991]

What amazing attention to detail. You created a work of art as well as a tool. I have been looking for someone who has these skills for years in Toronto. I am becoming convinced that you are one of the few geniuses who can still do the work that garages and body shops used to do everywhere. I am glad that you continue to use your talents in machining and metal work. Perhaps one day, I will get to see your workshop in person.

[@aussiecro.]

I have to admit...was wondering the whole video what the frig this was gonna do...didnt see that coming! Well done and kudo's!

[@MrNukealizer]

Am I the only one bothered that the U-joints on either end of the shaft aren't aligned properly? The yokes on both ends of the telescoping shaft need to be at the same angle to get constant-velocity output. With this 30° or so angle between the ends, the tool will spin faster than the lathe at some angles and slower at others, slightly messing up the resulting shape.

[@VesperCadha]

Damn... this synchronization is perfect!

[@ЕвгенийЧагарин]

Plagiat !!

[@andyneal3317]

Another one that leaves the chuck key in the chuck. BAD BAD.

[@paradiselost9946]

after much thought, i designed mine to drive a totally different way... toothed belt behind the chuck. this is also where the ratios are changed. easily removed spline shaft up the back, parallel to bed/ spindle. support arm at end of bed. sliding pulley on shaft. four bar "quadrilateral" tensioner with two idlers that maintain synchronisation as the cross-slide is fed in and out, and also slides the drive pulley up and down the splined shaft with the saddle. not supposed to have an idler on the driven side of a belt, but in this case is necessary as the two sides of the belt must remain symmetrical. still not finished, but so far its promising to allow for use ANYWHERE along the bed. which was the main goal, and the major shortcoming of every design ive seen... it means i can cut a hex or other profile the full length of travel...

What is this wizardry I just watched!?

[@BlackFenix-jz5rs]

Not gonna lie, it has to be the coolest thing to have the machinery (and knowledge) required to upgrade your machinery

[@Skwisgar2322]

This is neat, but you can see it doesn't leave truly flat faces. They are curved. It's probably fine in most cases, but if you need a true flat side, you will want to use a mill and collet block.

[@branchandfoundry560]

Or an indexing head.

[@Skwisgar2322]

@@branchandfoundry560 or that.

[@marknugent2775]

Neat setup, but it's not the best way to go about making parts like that. Also, by driving this thing off the lead screw there is the potential to cause a lot of damage to the lathe. Simpler setups can be made on a mill that will be much faster.

[@tookitogo]

I know that PB Swiss Tools uses CNC versions of this to make screwdriver bits and the heads of ball-head hex keys. They definitely produce flat facets as far as I can tell just from looking at them and using them as tools. I wonder if/how the ratio of the cutter radius to the workpiece radius affects the non-flatness of the facets?

[@ourfarmhouseinspain]

This is the modern equivalent of a misspent youth in a pool hall, except in a machinist with ocd. Excellent project, thank you. Regards

[@markissboi3583]

this baffles me how 2 rotating can make a square / hex head i need to see this in slowmo something missing. the journey continues

[@fuckingpippaman]

its the ration between the rotating chuck and rotating cutter. 2 diameters colliding while rotating with point contact. Imagine a 3:1 ratio between cutter and chuck. The cutter rotates 3 times vs 1 of the chuck, you get a triangle shape.

[@Pink404]

Did you ever play with a spirograph as a kid?, because that's in essence what is happening here. They're feeding off the thread screw which allows them to set the ratio of turns on the cutting tool relative to turns of the chuck. This adjustment of ratios is what allows them to 'draw' different shapes and the shape generation is sped up by them having three "pens" (tool bits) drawing at once. They could also change the number and distribution angle of the bits for different results.

[@wernerpfeifer]

Grandios 👍👍👍

It's always interesting watching your videos. It's great to see the things you can think of and then create.

[@Scootercorn]

Ok, I have no skills in this area, so I didn’t understand anything I watched. However, I pieced together (with significant help from the comments) that this guy designed and built a “flat edge drill press”-like tool that is kept in rotational synchronization with the lathe. This makes cutting a polygonal shape …. ON A LATHE 🤯…. simple. Wow, that’s incredible!

[@juniorsaw172]

Perfect👏👏👏👏👏👏👏👏

[@chrisdoucs]

I always find it really amazing and exciting how you make the threads. Could you please show in the future video how it is done at real speed? :)

[@syriuszb8611]

"Hmm, the gear does not support the bearing I have chosen, maybe my design is wrong? Maybe I am wrong? NO! It's the gear who is wrong! To the lathe!"

[@Thatdavemarsh]

Really impressed with your attention to safety detail. Great modification to your lathe.

[@f1reguy587]

How are the number of facets changed? And was there a speed change in the new part? I guess it works like a spirograph… its my first time seeing this type of add on, i only thought we could do threads, facing, drilling and rifling, but not machining nuts etc.

[@lesd40]

Awesome attachment! Almost hypnotic to watch.

[@Mac-sq2ly]

Маучы Петя не пытай

[@gregsmith3373]

I would love to see it running in slow motion. The markers help, but man I just can't wrap my brain around how it works, LOL

[@ptp51]

Spent all that time, money and labor to build what any mill with a dividing head can do. This was a project to show slightly above par manufacturing skills. Timing a cutting head to the headstock via the lead screw is a well documented idea but if it was worth the the implementation, you would see it as a standard optional feature on every new lathe. A+ on the video skills.

[@vitamint01]

Wow, a lot of talent exhibited. I am surprised you didn't leave the shaft belt driven vs. making the geartrain.

[@homemadetools]

Excellent work and video production as always. We shared this video on our homemade tools forum last week 😎

Very well done! I never thought about it until seeing this, but could you use light pressure on the buffing wheel or a scotchbrite or sanding drum to add alternating bands of polished/matte finishes to things?

Adam Savage I believe once said the Metal Lathe was his favorite tool because it's one of the most basic automated tools that can make another of itself. I see the same applies to making upgrades.

[@charliepearce8767]

My lathe is like a musical instrument. I get to play a different song on it with different jobs when needed. I bought my lathe 1994. It paid for itself in the first 3 weeks. It's been a wonderful tool, helping to build many other tools in my workshop, from sheet metal folders, hydraulic log splitters and a host of other wonderful machines to make my life easier and $$.

[@TheRealFOSFOR]

I can't wrap my head around, what happens with the uncut parts of the work? Won't the corners hit and rub against the cutter body?

[@DiakosDelvin]

The cutter is synchronized to the chuck so it can't hit anything it's not supposed to (unless a gear slips) like how old aircraft machine-gunes were slaved to the engine so it shot between the propeller blades.

[@TheRealFOSFOR]

@@DiakosDelvin It may seem obvious, but I'm not certain that only the cutting edge contacts the part; perhaps the entire cutter body does as well. As the uncut corner of the part approaches the cutter body during deeper cuts, it should get increasingly closer, possibly even making contact eventually.
