It seems like a 4" PVC pipe with one end cap would fork fine, but I wonder if the glue would hold up?

I'd rather ask before I do something that leads to a huge mess, so what have you done that worked?

Thanks. beer

Yes Evaporust in the PVC tube is the way to go

I did mine in a galvanized water tub tilted sideways. Took a lot of Evaporust and ate the galvanizing

I did mine with 4" PVC, glued cap, with Evaporust. Just to be safe, I placed the bottom end of the PVC pipe in a plastic coffee can in case of leaks but the glue was unaffected. Worked great.

The glue will eventually fall apart, but it takes a long time. You only need to soak it for a day or two. I did my drive shaft, then let a friend do 2 of his before it finally gave way.

Your driveshaft will probably float in Evapo-Rust or water with the top end sticking above the liquid, so you will need to find a way to keep it completely submerged to get de-rusting all over.

When finished with the rust removal, you'll likely have rust pitting on the tube. This is the norm for almost-50-year-old drive shafts.

If you want a factory fresh drive shaft, where the original end castings are gouged off and new tubing welded on, this guy was at Carlisle 2016 and apparently does excellent work from the looks of the driveshaft he had on display:

Rob Brombacker, (734) 564-3856, rbrombacker at specproj.com

He told me that he keeps his own driveshaft looking like new by painting or spraying a solution of Cosmoline thinned about 50-50 with mineral spirits about once per year. This was what he said when I asked him if he used RPM. Here in Houston with high humidity and 50 miles from the Gulf, I will probably use both on bare steel parts.

He's doing one for my AAR right now, he's as good as it gets if you're looking for perfect OEM.

The PVC works great. The driveshaft will float like "kentj340" stated. I put a heavy brick on top of the shaft, then covered the PVC with a gallon Ziplock bag.(don't want that expensive EvapoRust to EvapoRate)

what has everyone done to bring back the shiny steel look. also does reheating the welds give them that new appearance. I remember this was discussed a while back. I would be looking for a way that does not involve paint. mine is not that badly pitted

As won't fit in most bead blasters, I would sand blast it.

I tried scrubbing with several grades of steel wool and oil. It didn't work. Looks like a more aggressive approach would be better, maybe #600 paper with oil and working up with finer grits?

Burdar - that drive shaft looks great!. I assume you used maybe 4" PVC pipe with a hard cap on one end, put the shaft in, put assembly upright, then flooded with Evaporust while weighting the shaft with the brick?

I talked to the guy that does them listed above and the problem is finding a very clean un pitted cast ends on your orig shaft . If you do then this is the best option so far for a concourse quality resto . He had a few with him at Carlisle that looked amazing .

Yes, a 5' section of 4" PVC with a cap on one end. The shaft in the picture was 3.5" in diameter so there isn't much extra space between the PVC and the shaft. It doesn't take much EvapoRust to fill the tube. I would suggest trying to find a cap that has a threaded plug in the end. It would make draining the tube much easier.

I actually used vinegar to take the majority of the rust off this time. The EvapoRust was used last to keep the shaft from flash rusting. I sprayed some WD-40 on it for protection while it's stored. It still needs to be cut to length for use on my project.

As far as getting a more original look, I've watched a few Youtube videos where they sand the shaft with emery cloth while it's spinning on the balancer. That might get it close...
