Has anyone done World's style milling on a powder coated chassis? A buddy of mine asked if I would mill his but we are afraid the powder coating may get messed up at the sides of the milled areas? Anyone have any experience with this?

it probably will get a little 'furry' on the edges, especially if the area you are milling gets warm. Might not be so bad if you are using a water spray on the mill.

sorry, not much more useful than that.

Thanks for your reply. Can the edges be cleaned up after with an xacto knife? Got any pics?

Figure it out...I have some PC chassis too same color I bet!

Yup, you got it Joey, the twin to your chassis.

Sorry, I don't have any pictures. I would expect that if the prep work was good, you can trim up the fuzzy edge with a sharp blade afterward. The only concern is that the prep being poor would result in lifting on the non machined area. aluminum is a pain in the butt, nothing really sticks to it well.

Thanks. I guess there's only one way to find out...
Now who's going to volunteer first: Justin or Joey?

I milled a powdercoated chassis and it came out great. I just had to clean up a few edges with a razor, but only because the coating was hanging down in the milled areas. The coating at the edges of the milled areas is perfect once you clean it up.

I masked the bottom and sides of the chassis with blue painter tape to protect the coating


Squaring it up on the mill


And finished

Nice work! That turned out really nice and looks great in the red.

Nice red, that really does look pretty good!

PM me your address

Thanks guys!
Yeah, the red with the milled accents looks pretty sick. He's going to build the car with white plastics, should look amazing!

Mine is built all black plastics, but needs that milling love

That worked great! Good to hear!

It turned out nice!
