After a pair that give me the same ratio as drill gearboxes but something more solid than just putting gears on the end of a drill box, anyone help me out?

I have few around. Just the head of an anglegrinder. -
I don't think it will be so simple. Matt is after a 36:1 or 24:1 standard drill ratio over the 2.5ish:1 of chinese grinder gears. You'll need an extra stage in there somewhere. Possibly keep the first 6:1 stage of a drill planetary gearbox then have the angle grinder gears on top of that. Will be less reduction than a full drill gearbox but its probably he most you can get without getting into stupid money.
Alternative would be some bosch 35 motors.Comment

That I can't supply. Not inside a reasonable timeframe.Comment

Haz is right, need something along those lines but not after speed of delivery as long as I get the correct product. Trying to avoid bosch 35's if I can as I would like to keep the speed and power I have but a more compact space would allow for better protectionComment

Angle grinder gears are by far the cheapest way to source semi-decent right angle reductions. Limits things to about 2.6:1 in the right angle stage at most. To get in the region of drills, say 30:1, you'd need a further 11:1 reduction, which you won't get in a single stage after/before the grinder gears. You'd need three stages. This is the issue I face with Rango, as it happens.
You could get a pair of Bosch 35s for cheap, whereas triple-stage custom 90deg gearboxes could cross into the hundreds easily. I'm sure someone has some 35s.Comment

The Bosch 35s are a reasonable package and plenty available. The issue to contend with is the plastic worm gear and square shaft fixing. I dont have the patience to hand cut a brass gear to replace (there is a thread somewhere on here)Comment
