What to do with rear end?

[Supercharged111]

I sandblasted the rear end on my dually. A wire wheel would not have cut it there.

Got the 10 bolt out of the way! And picked up the 14 bolt yesterday. $500
Now I will be looking to get the old leaf springs and the new rear end all painted up. Any ideas on how to sand the rear end are welcome. How much is a sandblaster?

Sandblaster for what? That thing looks clean?

For any sandblaster to productive, you need TONS of CFM. That means a HUGE air compressor. 7.5 HP beast draws like 40Amps of electricity working non-stop. The guys that media blast for a living have diesel tow-behind compressors.

Anyway, that things looks clean, just a wire wheel on an angle grinder will be fine.

Maybe to sandblast professionally, but I've had great results with my 22 gallon Lowe's compressor.

How about this one from Matco? I've never used it, I don't even know how much air it takes?

So you're going to use a spot blaster? How old are you going to be before you're done? That's like painting the Golden Gate Bridge with a bottle of Testers model-car paint, and a Q-tip.

You'll wear out the threads on the cap from having to refill it every ten seconds.

I have an enclosed blast cabinet. I've put stuff as large as inner fenders inside--certainly not an entire axle assembly. My 5-horse, 80-gallon, two-stage compressor can just keep up. I had a 5-horse, single-stage, 60 gallon compressor that would not keep up; but would work well enough for blasting smaller parts.

Sandblasting in general takes an enormous amount of air.

Yea I’m only 26 and I’m sure this will not be the last project that I could use a sandblaster. Also an electrician so any power hookup for it would be a breeze for me. Figured it wouldn’t be a bad investment. But I’m looking to knuckle down on “the rona build” and stick to this before I start anymore projects around the house. So wire wheel it is.

Well it took about 3 hours and A 12 pack of Budweiser but I’ve finally got it ready for some paint.

HaHaHa!

Very true.

Okay so after 6 pages no one has suggested to him that he might need to make a change to have the (new and different) rear axle with the larger brakes actually contribute to stopping the truck ? I bet it takes a different master cylinder for the larger wheel cylinders to have enough fluid to engage the larger shoes and drums . . But maybe I'm just tired . Check with your Napa auto parts store and have them see if the master cylinder is the same .

I didn't change masters when I put my 9.5 in. Never occurred to me that the wheel cylinders might be a different size. Worked OK.

Now that I've upgraded the front calipers from the JB3 to JB5, I've got a larger-bore (1 1/8 instead of 1") Quick Take Up master to go with them. Not installed yet, but "on the list of things to do".

If he's got JB5 brakes, he's already got the larger master cylinder.
