Have been playing around this evening with pictures of the RM-531 Balance Plate and some photo edit software to come up with a pattern to make the balance plates.
Just so happens I have a 318 crankshaft here in the house for fitting the balance plate pattern to.
Don't have a good straight on picture of the RM-531 at the moment, that would keep things in the proper proportions to make the pattern.
Rough Draft for now...

This pattern is actually on upside down > need to flip it to get the offset of the bolt holes to line up correct, and have the weight in the right position for balance.
Half the fun is thinking through it and see what you can come up with.

Would be much easier just to take the actual RM-531 part off my engine run stand 360 and take it over to my Minnesota neighbor who works sheet steel. He could probably run off 10 exact duplicates no problem.
Only prob... it's 1700 miles away and doubt I will be getting back this season as Winter is coming on again.
Will stay where it's warm for now. I may be able to get a proper dimension template by doing some reverse engineering with info I have available.
