just my luck.. powder coater ruined coil pack covers sand blasting!!!

[1990jmcturbo]

well this starts as I took my coil pack covers in to get powder coated. when he sand blasted the old powder coat off. he had the regulator set at 200psi and it melted the corners folding them over.. so I went and picked them up after the fact they didn't like the idea what it cost to replace them. I took them to work, used a torch to straighten them out. tig welded them back up, placing steel behind it to try and keep the aluminum from closing up the gasket groove since the aluminum wont stick to steel. then put them in the Bridgeport and cleaned up the gasket groove back in it and cleaned up the outside. pretty happy with how they turned out for the circumstances. at least this got me some free powder coating LOL they are back getting coated right now.

I agree with the above..l super nice work fixing their error!

On aluminum parts its best to use Aircraft Remover (stronger version of Zip-Strip) to get the powder coat off the part. Trying to sandblast it off requires holding the gun a long time to abrade the powder coat away which will eat thru the exposed aluminum at the same time.

Glad you were able to salvage the coil covers.

I fabricated probably the nicest all aluminum baffled road race oil pan for a mod motor and was very careful to ensure the welder didn't warp the pan by applying the weld and heat evenly. All was hunky dory until I instructed him to apply a bead of weld at the very ends of the flange to minimize the material needed to be removed due to a slight bow along the flange where it was to be milled flat on a Bridgeport. My mistake was I left the pan for him to do this last step and the guy got stupid, went way overboard with it and warped it so bad the pan is unusable. The only way to fix it is to mill the flange completely away, cut the pan in half and re-level the front and rear welding it back together then weld on a new flange.

In the end this was my fault for not supervising the work. Most welders I have encountered the extent of their knowledge of these issues stops an laying down a good bead but not much else.

Never assume shops know what they are doing. I've talked to a few engine builders and after talking to them I ran in the other direction as fast as I could!

Who did you take them to originally? I've had really good luck with QC Coatings.
