I'd send the drawings to John Stevenson attached to a suitable number of beer vouchers

Hello Donald.

"I can work to about 2/10 of a thou with that file, who needs CNC" ?

I do. I have tendinitis in both shoulders so can't be more than 1 or two minutes with a file swinging back and forth...

But I must say that by now I haven't CNC at home.

I would like to have, but will not abandon manual control of the machines. I like it very much. Except when it contends with my shoulders or patience...

In fact I'm expecting the announced Tony Jeffree article about lathe screw control to start a new project.

In chapter 5 “Line Shaft”, 6 "Machining the gear cutters", 7 “Machining the gear teeth” and Appendix A “You can machine Skew Bevel gears” of his book The Climax Logging Engine (ISBN 0-914104-09-8) the author Kozo Hiraoka details everything you need to make bevel gears in your lathe. He details the jigs, gauges, the cutters and the formula etc. He also tells you how to make the stuff and then to cut the wheels,

Hope it helps.

Ok he is working with ‘skew gears’ but you just omit the ‘off set’. You may have trouble getting the correct ‘wire size’ for your 6 DP 10 tooth cutter. I do not know where to find them. 'Hiraoka samma' tells you how to calculate it.

I have used gauge plate to machine cast iron valve seats. Take it slow and gentle and you can do it.
