Hi,

I have the opportunity to claim a free surface grinder, yay! My
college roomate is *really* going to kill me now....

It looks like it was bought by a lab, never really used, now
dumped in the hallway. The ways are unworn, the gears unworn;
but the paint is flaking like seriously sunburnt skin.

After a good scraping and maybe a little sanding, I imagine that
I can get it down to mildly rusted cast iron. But on the machinery
I've used, they don't just paint it with latex housepaint. I imagine
that might simply peel right off again....

What sort of paint do I use?



thanks!
-Bernard

use a suitable two part urethane if you can afford it, next choice catalyzed
enamel -

I prefer 'RustOleum' silver gray. Multiple coats.

Budget? Rustoleum is popular at the low end. Farm implement paint has
also been mentioned as a good choice - if you have a tractor, you can
have matching machine tools. At the more expensive end, various types of
epoxy paints come up, or take it down to the auto body shop and get it a
tangerine metallic flake paintjob with flames and 12 coats of clear coat
in catalyzed lacquer. Don't play with catalyzed lacquer at home, it's
nasty stuff.

go down to your local hardware and ask for a tin of machinery grey
enamel.
alkyd enamels are good.
single pack epoxies are good.
essentially you want a solvent/oil based paint not a water based
paint.

a wood chisel can be used to lift off old paint then
wire brush, scotchbrite, steel wool and kerosene followed by a wash
down with mineral turps will give a good painting surface
(or it has on the lathe I'm restoring)

two pack paints are ok but the single packs are easier to touch up.

There is also a plastic wheel with plastic fingers sticking up
perpendicular to the pad that does a superb job on paint- the only
downside is that it wears out really quickly. But if you've got an
extra $50 and a die grinder, it's a slick way to go- just don't use it
on the ways or other components where precision is an issue.

My vote is for the tractor enamel mentioned. That's what I'm using on
the turret lathe I'm restoring, and it holds up well. The alkyd
enamel, if it's the stuff I'm thinking of that cleans up with ammonia,
won't hold up very well to direct exposure to water or coolant, in my
limited experience with the stuff.

I looked at those nylon wheels and thought they wouldnt last long.
when the steel wool didnt last long either I broke out the wood
chisels. it is mainly what I use them for.

The paint I'm using is White Knite single pack epoxy rust preventative
paint. It is made by taubmans.
It is probably a compatible paint to the rustoleum mentioned before.
