Building a Gear Shaper

I've tried to make internal gears by a number of methods in the past, but it's never quick, easy or reliable with normal hand or machine tools. The gear shaper is the perfect machine to do this, so I thought I'd have a go at building one.

This has to be one of the best, if not the best diy machine builds I’ve seen on YouTube yet. Your use of the donor mill casting was a great idea. It retains the quill functionality to get your reciprocating motion (shaper motion) and you get the dampening properties of cast iron that all proper commercial machine tools are built from. Most diy machine tool builds I’ve seen are of the “built up” variety, with housings fabricated from steel plate and bolted together or a combination of bolted construction and weldments. The cast iron construction being more rigid and thus more ideal for machining.
Can’t wait for part 2!!

Absolutely fantastic! can't wait for part 2! I love that you are re-using/re-purposing old item to make a completely new machine- that in turn makes other parts for other machines- Brilliant!

Amazing man, most content creators would have stretched this into a 15 part series. I love the high-level overview that shows the most interesting parts of the process in your style of filming.

Very impressive, taking the old mill and converting it like this, so clever. I'm looking forward to part 2

Simply the best. No other teacher, which he definitely is, can transmit so much information in such a precise and clear way. Learn from him and you will be a better machinist, his ideas for obtaining a very complicated process in a simple attainable way using available parts and new technology are outstanding. Congratulations 👏

That moment when you wanted to make internal gears for a while now - and have a spare milling head... Looks like another project for myself down the road.

This is awesome! Thank you for sharing this!

I love your videos so much. The effort, skill, and knowledge are immeasurable.

[andrewdolinskiatcarpathian]

Astonishing vision, design and execution. Well done on such a brilliant build. 👏👏👍😀

[garygenerous]

Absolutely amazing work. I love seeing you take crappy chinesium machine tools and turn them into other machine tools with amazing precision. Can’t wait for part 2!

What a great start to the weekend! Always a delight to see a new video.

Fabulous project, fabulous work, and fabulous explanations. Thanks for sharing this with us.

Now that is a LOT of work.
WOW... a very impressive build!!!

[charlvanniekerk]

FINALLY !!!! I HAVE BEEN WAITING FOR SOMEOME TO TREPAN SOMETHING FOR YEARS!
Incredible build and some amazing techniques. This really makes for an incredibly precise piece of equipment and endless possibilities well done!

Really neat stuff! One of the few channels I don't FF through at some point. Probably a combination of the overall length and not wasting a lot of time showing completely obvious disassembly in fast-motion. The subject matter is most important, of course, and I find this inspirational as I'm mostly an amateur hack machinist.

[Dooban]

Your channel is awesome and extremely underrated.

[DudleyToolwright]

Very interesting project. Thoroughly enjoyed.

[georgedreisch]

Simply brilliant! Looking forward to the math involved to get it all to sync.
Also hoping on more elaboration on inside gears, particularly, tooth profiles.

[rickpalechuk]

Cool build Andy, looking forward to the rest of the series.
Cheers

[brucewilliams]

Very impressive! You do such well thought out projects.

[hpevans]

Fantastic work Andy, you certainly have a wide range of skills
