In my opinion, the manufacturer was a little "lax" in the lamination finish, so you may want to refinish them. I've refinished the ones I've used. It's not that big of a deal to do.

Anyway, keep me posted.

What can you suggest to improve them in that aspect?

Best regards!

I just use a razor blade to smooth off the rough spots, then I put on a couple of coats of satin-finish varnish.

My cousin painted his with semi-flat hi-temp black paint.

Ain't it dangerous to scrap those laminations, in the sense of shorting laminations? I mean, afaik laminations are insulated between them, right?

Yes, they are insulated by the oxide coating.

I'm not talking about using a belt sander here. I am not shorting the laminations, just scraping off the high spots of existing rough varnish.

Good to know I would've just hit them with some sandpaper and sprayed them.

Now I know better than to cause a dead short.

That is why I just use a single edge razor blade to cut away the high spots and drips. I go in the direction of the lams, not across them. I'm not actually getting into the metal. It's not hard to do.

I got some sanding blocks to knock off the "run" that looks to be at one corner of the transformer lams. I do understand the need to avoid shorting the laminations. I got some flat black hi-temp spray paint for these, and the motor run caps.

Question - should I make sure that the clamps for the motor run caps make electrical contact with the cap for grounding purposes? I could either tape off a section of the cap below the level of the chassis, or sand off some of the paint before mounting.

Yes. Either method will work.
