Thanks to 38ac I got connected with another member Robert Leonard, who had some SOM flywheels for sale. Bob did a great job of securing them to a sturdy pallet and getting them loaded on my freight carrier 8 days ago. Today I picked them up at my local helpful Ace Hardware.
They are now on my shop apron ready for some clean up and new paint! They are a bit shocking to a someone only familiar with Rajkot castings; there are no voids, putty, bondo!
I'd like advice on your favorite rust treatment that does not involve Rustoleum type oil based paint. I just can't stand the stink of it. I'm thinking sand and wire brush, naval jelly, then paint. I'm in AZ, USA, so continued rusting is not a big issue, I'm just proud of them so want to pretty them up a bit.
