Thread: How to cut gears

POD I would be interested to see how you go doing internals using the shaper. I bought myself an old Douglas shaper. Only got as far as refurbishing it at this stage. Need to figure out how to fix the job with indexer onto a relatively small table.

I have a set of involute module one gear cutters for use in my mill. Bought them out of curiosity as a starting point.

Cutting the gears is one thing, but I would also like to know how to choose the right steel for the application and then surface harden the teeth in a home workshop.

And why can't I find single involute teeth made of carbide so you can cut already hardened steel? Maybe to brittle for intermittent contact cutting?

Too many interesting things to do in one lifetime,,,

Ain't that the truth!

Doing splines on the shaper will necessitate making an extension to the table, the dividing head will have to sit out in front of the machine. That project is a fair way down the list at present. Internal keyways took a little bit of setting up but once the tooling is made it's nice to let the machine do the hard work.

That lot should keep you going for a while...

Clickspring is the pick of the bunch, inspirational work and the video production quality is on a par with a professional TV show. A lot of those guys are a bit too longwinded for me. Check out Tubal Cain also, an experienced machinist and a good educator. Be warned, this stuff is more addictive than Landies.

Yes, Clicksprings production is some of the best going, he is very fastidious with everythung he does.

Some of the others I watch a 2x speed to get through the boring bits, but I like them all for different reasons, and have learned things from all of them.

The etching press that Ox Tools is building is also very good.

Dan Gelbart has an interesting 18 part series on prototyping, not all about machining but interesting enough - can't help think of him as the Woody Allen of the work shop with some of his deadpan humour. He also has another on the building of a granite based high precision lathe.
