Hi everyone, new here and is my first Post
Hi Blair, and welcome to the group!
do have an extra 6 DP, 14 1/2 PA, #6 cutter available. How about $20 plus shipping?
BTW, I do have a 6DP14-1/2* gear cutter but don't know which number it is. I don't use gears that big so never checked. 1 inch mandrel, it came on the mill when I bought it. You're welcome to it if it would help.
I guess you have already seen first hand how friendly and helpful our membership can be!
Although I cannot directly answer your question on whether the 20 tooth gear can be cut with a #5 cutter, I can offer two things:
1) a warning; be careful with trying to specify the cutter by cutter number only!
It seems that North America and Asia have an inverted sense of cutter number vs. tooth count!
Cutter Number | Standard Tooth Range (from Machinery's Handbook 30th Edition) | Tooth Range (from current ebay offerings; and the latest set I bought from China) |
1 | 135 to rack | 12-13 |
2 | 55-134 | 14-16 |
3 | 35-54 | 17-20 |
4 | 26-34 | 21-25 |
5 | 21-25 | 26-34 |
6 | 17-20 | 35-54 |
7 | 14-15 | 55-134 |
8 | 12-13 | 135 to rack |
2) an offer;
Plastic change gears are used by many new lathes.
If you would like to try a 3D printed plastic gear I could make one for you.
If you give me the full gear specs, I could print one (in PLA, ABS or Nylon) and send it to you.
All I ask for is an honest, detailed review of the gear here on this site.
Use it for a while and let us all know how well it holds up....or doesn't hold up and we'll try a different plastic!
That kind of review would be useful.
