Rust Removal Method Question for Front and Rear Spring Restore

Re: Rust Removal Method Question for Front and Rear Spring Restore

Here is the process to get back to factory look;
"Shot peen entire surface after heat treatment. Peening intensity measured according to SAE J442 specifications must be .012-.015" A. SAE 330-390 cast steel shot desired".

"Spray or dip with Lucas Rustproofing #635 compound or equivalent for rust prevention. (mix 7 parts water with 1 part rustproof compound)"

From past talks with those who know better than I.

My coil springs were not in good shape. One had an arc to it and both had settled. There were 1/2" spacers under each to get the ride height close when I took it apart. I replaced them with Moog aftermarket springs, about $40 from Rock auto. Just about everything I've read says the car will sit too high with tthe aftermarket springs. For that price I figured I'd give it a shot. It doesn't sit high and the Z dimension is within spec.

Alan, I read a little about shot peening and I'm not sure I understand the approach here. Also, I don't plan on heat treating the parts. I'm hoping there is a simpler process to return a glass beaded surface back to original the original bare metal color. Can someone elaborate on this? Does anyone have any excperience with any other approaches to this ?

Re: Rust Removal Method Question for Front and Rear Spring Restore

I have used " Evapo-rust" for several projectsa. The main downside is that it is quite expensive. I felt lucky to get 5 gallons for less than $100 including shipping. One of the things I did was a 1950 Ford grille. The stuff exceeded my expectations. Since it works by "chellation", i wouldn't think there would be Hydrogen Embritelment problem, but I'm not a chemist (and I didn't stay in a Holiday Inn Express last night, either). I do know you can stick your and in it with impunity to retrieve lost parts with no problems. If it was 3.99 a gallon, I would be buying it by the drumfull. I hear that a molasses solution works just about as well, and I will be pursuing that avenue.

Check out Safest Rust Remover. The stuff is water based and very safe. Works excellently!

They will smoke a bit, after that then treat with BioShield.

Mike -

Springs look great! I think you meant Boeshield, not Bioshield.

Haha...Thanks John you're right, Boeshield....I think the Boe came from Boeing who developed the product.

I have used the molasses and water mixture on seat frames and it worked quite well. I don't remember the ratio but it can be found online. Got the molasses from the feed store. It does take longer in the solution but is less expensive than evapo-rust.

Re: Rust Removal Method Question for Front and Rear Spring Restore

FYI - Nothing to do with removing rust off the springs, but front spring tags face inward, not outward. The reason for this is so that they did not get damaged or come off during shipping so the assembly line worker would know what application they were for.

Your are such a stickler for correctness you must be one of those judge types.

Just a comment on your beautiful craftsmanship on that restoration great work. You put a lot of time and effort in that.

Actually, shotpeening works quite well. Think of it as blasting with tiny little balls (i.e. shot). It really does come out looking good.
Then, as noted in other posts, you can coat it with a preservative and it will be the correct appearance.

The trick is finding a place that will shot peen it for you.

A local store has a 50lb bag of shoot penning steel pellets. Anyone try using this as shot penning in their sandblast cabinet?

Steve,
You may not achieve the desired results with air driven blasting equipment, even if it will propel the shot.

Shot machines (the biggest name used to be Wheelabrator, but I see they are in the waste Management Group now. Try http://www.vikingcorporation.com/Cat...ry/BLAST_WHEEL There are also images of the exterior of their machines on this site.) work by metering shot onto a spinning disk. The speed of the disk and size and cut of the shot and the rate of metering are what determines the end finish as well as the abrasion of the surface. That abrasion of the surface will make changes to the rate of compression of the springs or the strength of the half-shafts. Those changes may or may not matter for restoration purposes, however. Let us know how your experiment works out.

Personal opinion I would not use them in my machine. Probably have a tendency to eat the machine up. Walls are thin in most glass bead cabinets.
