Good morning members.
This month's cover photo shows a group of gears that I machined using a CNC DDCS control box, a home-made indexing head, and?a subroutine g code.
These gears replace the original factory plastic gears in a Real Bull mini-lathe. I did buy a set of replacement gears steel gears, but these were very noisy,?as the center line distance or pitch diameter between mating teeth was excessive. So I decided to make my own using aluminium.
Photos show 12 tooth, 20T, 21T, 29T gears and the use of a MOD 2 involute gear cutter.
The root diameter of the teeth were cut out using a 3 mm wide slitting saw.
Any questions please ask.
Thanks
