I can't imagine that they would be at all difficult to make, if you had a sample gear of another number of teeth, all the other info, such as the OD and depth of tooth is either in Machinery's Handbook or stamped on the cutter, the diametral pitch can be deduced from the OD and the number of teeth on an existing change gear or with a pitch gage.

Yea i don’t have any gear cutting tools, right now. I hoped someone had a drawing for those gears I could send a copy to Boston gear and get them made. I just don’t need the gear cutters that often. In fact I have never cut a gear in my life. Of course I need one now.
These are the gears for what they call near metric threads acording to clausing. I’m still waiting to see if they have a draw, so far still waiting. I do have a vertical rotory table, with a 4 jaw and index plates. Not sure what the DP, or any specs are for the clausing stud gears.
Thanks
CH

I have the wherewithal to do this for you, all I'd need is the present change gear that these would replace.

Well as best i can tell the gears have a 11/16” bore, 1/2” wide, 17 tooth, 16 pitch 14.5 pressure angle. The other gear is same but 23 tooth. The gear that is on there now is 11/16” bore 1/2” wide, 18 tooth, 16 pitch 14.5 pressure angle. Does this make since? I’ll have to remove it to get a good diameter messurment

Yea I got a call from Clausing this morning and they found the last 2 gears in the warewarehouse, NOS so bought both the 17 and 23 tooth gears. He said it was just luck they found them. They won’t have any more so thought I should buy a powerball for tonight LOL
Thanks for your help and your offer. I guess i should learn to make a gear or two, woundering if thoses Chinese cutters are any good. Looked at some US made that was like 267.00 each thats more than the lathe cost me for those. I hate to buy chinese when I can get US made.

Wonderful! I think you could find lots of cutters on e bay for much less; I have nearly two sets of all pitches from about 48 down to 3, all obtained quite cheaply.
