I had the top plate and trafo bell powdercoated (they coated all surfaces, was going to cost a fair bit more if they masked anything). I just want to confirm that I need to scrape the coating off the bottom of the plate at terminal 3,8, and the #8 safety ground bolt? Any other places? The transformer is isolated from the top plate so I don't need to worry about scraping any off the underside of the bell or plate on those 4 holes, correct? Possibly run a 1/4" drill bit by hand through the top plate transformer mounting holes if the fiber washer shoulder doesn't fit?
Thanks for any help!
