For someone else, so I have no idea where/how it fits.
Setting up the Hommel angle plate to mount the rotary table. Getting the traverses right is always a compromise.
Set up, using an M1 #3 gear cutter from CTC tools. It's not a critical thing, as this is for a ratchet.
Setting cutter height using rod of diameter same as cutter thickness, 4mm.
The supplied sample and brass blank.
The height setting "gauge in self centering 4 jaw.
The gear blank in 3 jaw.
Stting up stop for depth of cut - 2.5mm looks about right.
Setting up stop for length of cut. Once these are done, the process is pretty mindless providing you get the tables angular rotation correct.
Which I didn't, so the carefully pre-prepared end is messed up. This is a rotary table which doesn't do indexing, so you have to dial up the correct absolute angle for each cut - in this instance, it's for 24 teeth, so the angle increment is a straightforward 15 degrees between teeth, or gap. The table dials up 5 degrees per rotation of the dial, so it's reasonably straightforward. Except if you're not paying attention... having a spreadsheet of tooth number and required angle is essential, but you need to double check and not be distracted by domestic queries.
Finished. Now I can do what I want to...
