Finally made some more progress. Getting very close now to actually coating these cases.
I got both cases fully sanded and cleaned. I need to hit them one more time with some sand paper, because after watching an official Cerakote video I got a lot of information on the correct way to do it. Can’t be shiny and completely smooth. Need to clean them thoroughly with brake cleaner to remove all oils and debris, and also need to wear gloves to keep skin oil from getting on them.
Found out my dad has a semi-professional Wagner HVLP spray setup, so I will probably use that. The cheap spray gun I got has a plastic cup, but Cerakote needs a metal cup. The Wagner has a giant metal container. Only problem is the nozzle is too big; Cerakote recommends .8mm, the gun has a 2.0. I’ll try it out anyway.
I needed to make a way to get the cases to stand up on their own as well as hang from the ceiling. Some bolts and some small pieces of aluminum got that figured out. Four bolts sort of thread in to the four threaded holes on the bottom, and I cut some strips of aluminum to sort of make feet out under the fins.
Also put some bolts in the three threaded holes where the water block bracket bolts into. Just to keep the Cerakote out of the holes. You can also see all the holes that have been filled in with JB Weld and sanded smooth.
I’ll be using the convection oven feature in old microwave. The microwave part no longer works. Also took most of the casing off because the convection oven heating element was smoking very badly. But when I tried it again it works fine. Can only fit one case/piece in there at a time, so it will make coating parts harder and slower.
And here is a case and lid hanging from the ceiling. The bolts being used here are not the ones being used now. The shorter ones with the lengths of aluminum were needed because the fin side of the case was so heavy it would fall over, it wasn’t balanced. Probably won’t be an issue when the feet are on and there’s an aluminum plate with a motherbaord and resevoir weighing down the other side.
It’s been chilly here in Wisconsin. Single digits at night and teens maybe 20 during the day. Got a big wood stove and two kerosene heaters going all day to get the shop warmed up to about 50f. Hope it’s not too cold for the Cerakote. Also hope the small amount of smoke in the air doesn’t affect it somehow.
