to have more mass i need a brass ring made OD 140 mm ID 95 mm width 15 mm my taig doesn't do this size, the brass ring will be glued to the aluminium flywheel to make the hit n miss turn over properly (Hoppy made by a british firm) Please ,quote me on this ,thanks in advance, Manfred

Instead of glue, why not heat the ring and let it shrink to fit? Just a thought. Mike

I was thinking press fit and grub screws or pressed pins to locate it, glue just seems weak for a device that balances torque pulses.
I didn't attempt to find out where you are located I'm in Yuma AZ, but would be willing if your close enough to do the work on my machine's and press fit or shrink fit it to the part at the same time.

Is brass the choice due to weight, ease of machining, or looks?
If for looks I totally understand....

if for weight I would suggest steel or cast iron due to cost of brass unless your casting from scrap. Or lead....inexpensive machinable...heavier than brass.

Ease of machining.....brass, 12l14, steel, or cast iron are all ok.

Definitely shrink fit on that rather than any adhesive, even though there are pretty good adhesives available now. There would be zero doubt about a failure. If you shrink it fairly tight, no pins or screws will be required. It would look best too.

I will do it if needed...I may have a piece of steel close to that size...and could perhaps save 2 way shipping....what state are you in?.....Oh Utah. ...well that nit horrible far but still a good ways to walk.
Many people from Utah winter here in yuma az, maybe you can send it with one of them. Or flat rate it.

I apologize life kinda sidetracked me....then things at work got a tad complicated to say least...nope I not in trouble lol.
I have found a rusty piece I think will do the job....not sure if your in a hurry or not, if not I'll continue looking....I think I can turn up a cast iron dumbell or a heavy malable iron blind flange plate for next to nothing.

I was at a habitat for humanity store last summer and found cast iron barbell weights for $1.oo to $2.00 each and bought em all. I think they had six different weights of 2.5 pounds to 10 pounds.
They can be turned true and balanced as fly wheels or hand wheels er whatever.
Yard sales could be a good place to look for them also.
