Hi All,
 
Quick question regarding the best method of painting castings. I am building a Stuart 10H, and am ready to start the flywheel, but am usure wether to paint first, and then machine to get a nice sharp edge where the paint finishes, or machine first then paint, to avoid marking the paint during clamping, etc.
 
Is there a preferred method for this?

For flywheels I tend to clean up the casting around the spokes, hub and inside the rim then do all the machining. After this I paint it and finish up by polishing up the rim with emery, this will remove any stray paint. Should come up like this

Hi Jason,

Thanks for your notes, I was thinking machining first was a better route, but wasn't sure if the rim would clean up properly afterwards. If it turns out anything like your photo, I'll be more than happy!
