Now that I've got that all fixed, the compressor is running non stop and making water. I I need to get a water trap and may build an inter-cooler to help dry out the air.

Its taking less time now, did an elevator in about 45 minutes. It's definitely better than stripping in my opinion.

45 minutes is more like it. That sounds great to me compared to stripping.

As the weather cools and dries during the fall, I bet your water issues will get better. That said, running your air through a copper coil in a bucket of cold water will help condense the water. Then you need a downstream trap.

That's what I've been thinking of trying.

How's your project coming along?

I make progress when I work on it. But I don't work on it much. Right now, both wings are assembled except for tip bows and leading edges. A buddy has had all of the tailfeathers to blast them for about a year but is having equipment problems. I'm afraid I'm gonna have to take them back and strip 'em myself.

Guys,

My desktop took a dump so I have been off line for a while. Finally figured out how to use my iPad. Now I get to catch up on my reading.

Talking about primered parts and bead blasting, last year I ordered parts from wag which were painted with standard green zink chromate primer. I noticed a flake of primer coming off. So I ran my finger nail across the surface and large chunks of primer came off. I bead blasted the parts and repainted. The flakes were so large and numerous that I had to replace the beads.

Not trying to bad mouth Wag, I did not bother to call them. Since I caught it on the front end before top coat, it was no big deal. Just want to let every know to check the bonding of the primer before top coating.
