DS yes I have a compressor and paint guns, but being that I live in a subdivision and the HOA is itching to fine me, I don't have the space or proper area to spray. So I bought the aerosol stuff to take care of the small parts. I do plan on using epoxy, high build primer on the body.

Yea, think I'm still digging sand from areas I can't mention...lol.
The black diamond is a resin based product with a little bit of glass... I've never used sand as this stuff is cheaper ($5.00 a bag) and there is very little dust. I normally put a tarp or use it in a area where I can sweep it up, except this time. I'm sure it will kill my grass. Not sure what you mean by profile, but it cleans pretty well, doesn't heat up the metal as sand does...

Re: Jesses' 48 PU

don't you love it when a plan comes together? seems like we do a bunch of work and it looks the same. then one day it just seems to shoot ahead.
by sandblast profile I meant roughness of the surface. some abrasives are pretty rough and leave actual visible high spots. if the high spots aren't sanded down before primer the primer can just sink into the low spots and the high spots (we're talking about using magnifyers to see this but you can feel it) will end up with no paint on them so they start to rust quickly. there are 2 types of blast media. cutting and non cutting. glass bead is an example of non cutting. it blasts the paint ertc off because it spins when it exits the nozzle and hits the work. that removes the product you want to remove but the spin has less effect on the metal when it hits bare steel or aluminum. aluminum oxide is a really common cutting abrasive, like I use in my little portable blaster. it removes paint etc pretty quick but leaves a taller profile, though, so the blasted part needs to be sanded prior to primer. sorta like the difference between fine sand paper and course sandpaper. fine paper could be primered over and the abrasive would be covered with the primer. if you sprayed the same amount of primer on the course paper there would be the peaks of the grit not covered by the primer. in my blast cabinet I use garnet because it doesn't turn to powder right away and lasts longer. the profile isn't as big as aluminum oxide but I sand stuff anyway afterwards. aluminum oxide is really hard so it leaves a bigger profile than sand. sand is softer, like a #4, and explodes on impact so has less profile than alum oxide, a number 9. silicone carbide, a number 9.5, is even harder than alum oxide. when blasting and not recycling the blast media sand works fine. a blast cabinet automatically recycles the blast media.

Re: Jesses' 48 PU

here is a pic that shows what I mean about profile. it's like sandpaper. that is using regular sand at a u blast place. you can see the pock marks if you look close enough. pics turned, sorry.

Re: Jesses' 48 PU

Hey DS, thanks for the explanation/lesson on sandblasting and media. Honestly, I did not realize there was so many details to it. I've used this media several times on both my blaster and cabinet I like the results and I don't feel the need to sand with finer grit afterwards. Here is a pic of the angle support, it's pretty smooth.

Re: Jesses' 48 PU

Well I decided to do away with the old mustang fuel tank. It simply would not work with the LS engine without modifications, so I went with a TankersInc EFI tank, came with fuel pump, sending unit, hose and fittings. So I welded some 3/16 inch plat on the frame and went with 1.5 inch square tubing for the frame the tank will sit on.

Re: Jesses' 48 PU

My plasma made it easy to cut out the exhaust pass through holes.

Re: Jesses' 48 PU

Made a little jig/tool to cut close to perfect circles with the plasma. Took a one inch hole saw I had laying around. Welded a 1 inch flat bar, drilled a pilot hole 2 inches from center. After deciding where the exhaust would run through I Drilled a pilot hole, stuck a drill bit to hold the jig in place and Baamm! 4 inch circle cutouts... I will roll up some 3/16 metal tomorrow and weld them in.

Re: Jesses' 48 PU

how do you get a 4 inch circle when you are using a 1 inch hole saw, 1 inch flat bar and marking 2 inches from center.
4
+
1
+
1
+
2
=
8

doesn't compute. then ad in the size of the pilot hole plus the 3/16 roll. what does that come out to again?

haha.

looks good, mr "I have a plasma cutter"...Ö..
