I've had this brass 'thingy' sitting in my shed for years.
I have no idea what it is; I rather think it came from a garage sale.
It has a diameter of 226mm, and has 360 teeth which appear to be pretty accurately cut.
The centre bore(?) is 63mm with a steel reducer/collar which brings the bore down to 44.5mm
I'm wondering if I could use this as the basis of a DIY RA drive?
But where would I go to get a worm made up?
Some Brasso and a bit of elbow grease would make it look quite handsome!
I'd be interested if anyone can identify what it might be, plus ideas on putting it to good use?
Cheers
Chris
