Spiral Bevel Gears
efrench:
How did the printed gears work?
Joules:
They are only used to position and test parts fit. I can try combinations of parts and ideas, such as the spindle housing. I don’t yet have any final gears for the finished head, so that is dictating my design.
kayzed1:
I will look in my scrap box tomorrow for you as i think i have a gear or three in it..

An alturnative is to use two sets of angle grinder gears lock the pinions to a shaft , but you will loose power driving the first pinion .
Joules:
This is all on the little SU1 mill. I am fed up swapping the motor and spindle around. In horizontal setup the speed is too high, so am making new pulleys to halve the spindle speed. The plan then was to run a second belt to a line shaft in the overarm and drive a much smaller ER11 vertical spindle at higher speed. This is where the spiral bevel gears come in, I have machined a new boss that fits where the old vertical did and it is bored to take a 10mm shaft. The arrangement will be something like a miniature Schaublin 13 mill. I can develop and 3D print the vertical head casing before fabricating it in alloy. I also have a vague notion that the line shaft through the over arm can be used to power other accessories like a slotting head.
Oh, nearly forgot, thanks to everyone for the offers of help.
The motor has recently had a couple of hiccups and snapped an end mill. I am looking at replacing the motor and speed controller with an industrial sewing machine servo motor. They are compact, reliable and cheap. Very good option for a Mini lathe refit.
