Having had a think, and a rummage, I see I have some old white (and some very old, brown!) electrical junction boxes, as well as a fascinating collection of other obsolete things (like the light-bulb socket adapter so that you could plug your vacuum cleaner into the lighting circuit..., anyway, I digress).

What do you think these old junction boxes are made of? The brown ones may be bakelite, the white ones...? They're the hard sort, that bits snap off, not flexible at all.

I could use the flat lid of one of those, maybe... any thoughts?

Thank you. I would bore out a piece of tube, had I one suitable, but currently no lathe.

Adding a new ring over existing is an interesting idea and might be possible via careful electric drill bodgery.

Usure about new switches. Again, possibility I will have to look further into. The shaft is 3/4". Would a 19mm one go on, I wonder? The problem I had when looking is that they seem to be 1500RPM ones generally. The motor's plate says "Full Load speed 1410". I certainly don't want to damage the motor!

I had wondered about making a ring by soldering. Perhaps I could cut some copper sheet or even flatten some copper tube and use that.

Unfortunately I don't think there's room for a Jubilee clip, the button that the disc presses is not ver high and I think the clip would foul it.

I'd also wondered about filing a groove in the edge of the ring and soldering or guluing that.

I'm going to see if I can add a link to a pic. Fingers crossed! EDIT (again) I hope I hgave not broken the rules. I will scurry off to look them up and find out about psoting pics (Edit, edit, got there in the end, easy when you know how)..

Hi, I have an old Brook Motors induction motor (1440RPM) driving a circular saw. It's probably early 1930s. I was cleaning off a build-up of old grease, and stupidly dropped the centrifugal switch, and a woodrough key shaped part of the disc broke off.

So I degreased it and blew off the solvent with compressed air, and used (slow) araldite to stick it back together.

It would be nice to reinforce it, perhaps by putting a metal ring around the outside of the disc (imagine a section cut from a tin can), retaining it with araldite and folding the edges down to help it stay on. Something like that. However, I can'r fins ant tins of a suitable inside diameter (the disc is 2" diameter, by vernier calipers).

Does that sound a reasonable idea? Any suggestions, or anything else to do?
