Disassembling a frame for blasting
Hear my tale.
I have 2 questions related to sandblasting a frame. 1. The frame has a lot of surface rust. Would it be wise or even necessary to remove the cab mounts, bed mounts, core support mounts to make sure no rust is in between them? The truck is to be a driver, but I don't want rusty streaks showing up later if I can help it. 2. All riveted in crossmembers are to be replaced by porterbuilt crossmembers except the radiator support and rear most crossmember. I had planned on removing all others before I take it to the blasters. Today while removing a janky homemade hitch, I found a big ol' crack in the rearmost crossmember. So it's now coming out as well. This leaves only the radiator support to bridge the two halves together. How much grief am I asking for if I take the frame completely apart and bolt it all back together? |

That's a tricky one...I've seen it done...I left mine all together for blasting...ive also seen guys strip em down to nothing...getting the frame back square is gonna be the worst part i think...but if your down to nothing but the radiator support holding the frame rails then I don't think you got anything to loose...

Re: Disassembling a frame for blasting
Since you are down to just the radiator crossmember, I would go ahead and remove it as well to make it easier to handle and avoid bending that crossmember. Reassembling the frame and getting it square is not that difficult if you have a proper place to do it and take your time. You will want the frame level in both directions as well. As for removing all of the riveted brackets, that would be a sure way to eliminate the possibility of rust creeping out from between.

The guy I bought my truck in a box from had the frame powder-coated without removing the a-arm cross-member. When I removed it and the others there was still rust under there. Glad I did.

I appreciate the input, gentlemen. I like the idea of taking all the brackets off to make sure the rust is gone. I haven't verified this but I imagine I'm going to have to drill the rivet holes larger to bolt it all together. I'm going to do this one crossmember at a time, then blow it all apart for blasting and paint. I feel that should help with keeping everything square...ish when it goes back together.

I had my frame blasted then tore it down further, will get it redone again before coating. |
