Gettin' an old rusty spring back to prime shape

Hey guys, I'm gonna start assembling my '40 Ford front end soon and I'm gonna be taking 3 leafs out when I do that. Heres the deal, while I got the spring apart I'd like to get it into nice shape rightaways so I only have to dissasemble it once. It's rusty and full of crud. I'll wash all the leafs with varsal first and get all the grease and crud off. Should I then take a wire brush cup and use my grinder to clean them? Should I polish them? Or paint them rightaways???? I'm not sure how they're supposed to look. Or will just a basic clean up be good enough for the spring to compress again. Right now it seems rusted shut and has VERY minimal movement with 2 heavy guys jumpin on it.


Thanks,


Mike

Flapper.

Flap discs work faster and better than wire wheels. They're like grinder discs, but they have little "flaps" of heavy duty sandpaper layered on them. Plus, wire wheels always shoot little strands of wire everywhere as it's used. After the flap disc job is done, clean them with a parts washer for good measure. Then paint them. Polishing isn't going to do much on mild spring steel unless it's chromed.

If you can afford it, put teflon (I think) strips between them........if you can't afford it, some grease would work also. Softens the ride a little.

Sand them down

I use a fine sand paper or emery to clean something like that..one or two leaves of the spring may need to be removed as well for a lite T like Night fire is building..

Old skool trick is to use window screen between the leaves with a thin layer of grease in there..makes em real slippery..Then paint the spring..

Just did my rear springs last night. Took a wire wheel to them a couple of nights ago to get all of the loose stuff off which cleaned them up pretty well. By all means if you want them spotless use the flap wheel. After that I put a "rust stop" product on them. After 24 hours, which was last night, I painted them and they turned out nicely.

I cant afford powdercoating. I'll clean them up with a wire wheel (I've used flap wheels in the past and I find them too agressive, kinda like an actual grinding wheel, they can grind into the metal and leave divots) and some Varsal and once they're all cleaned up I might sand them down a bit by hand. Do I pain the leafs separately or do I put it all back together and then paint the whole spring?

In the past I've both painted separately and as a unit. If you are taking the time to break them down, do them individually and re-assemble with either the rubber insulators and a little silicone between the leafs or scuff the paint lightly and apply a thin layer of graphite grease on the contact surfaces when you assemble them. Either method will keep them quiet for a few years.

Been wrenchin' on rods for nearly 50 years and never heard of the window screen trick. Makes sense. Thanks OneMoreTime.

Grease between the leaves will attract and hold dirt and grit causing noises and wear.

My preference is to sand blast the leaves, Prime them, then paint them and put teflon between the leaves. As was mentioned earlier this is the best you can ask for. A good shock set up is usually more important then the spring on these cars. You didn't mention what you are doing about shocks or bushing which have a lot to do with the ride. Just one old mans opinion.

I also recommend the teflon strips. I added them to the front spring on my Model A after I had a few thousand miles on it, and I was amazed at the difference. That stuff is cheap, and it really works well.
