  • Shim Stock.

    Ok, show of hands just how many of you have tried to separate a .001 shim from the bearing shim stock?

    I have NEWS!!

    I just figured a better way to do it without pealing them up like curley que. I have this tool that is called a "resistance solder machine" and basically what it does is has 2 wires which electricity is passed through to heat up an item, kinda like welding, only it is made for soldering.

    Now here is the trick part, I placed a block of shim between the tips and threw the juice to it, which smoked and while heating up the shims, burnt the stuff holding them together.

    Now, I know that only maybe one or two of you would even think of owning one of these, but here is the idea.

    Take your favorite charged up battery and hook some decently heavy wires to each terminal, say battery cables, and carefully hold the two cables against either side of the shims and it should heat the shims up enough to burn out the adherent.

    This should separate the plates. Now, say you break them all loose and want to place a few of them back together, easy peasy, just use a bit of finger nail polish between the plates and clamp it back together, the polish will hold them.

    I just found a small flaw in this idea, try to only heat it up enough to burn the stuff out, if you heat it too much, you could weld them together, like spot welding.
    You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command!

    Thanks Wiz
    I think Chief has one of those solderers. Here is a tech thread on the subject

      Heat up a piece of steel,any kind of scrap,probably 1/4 inch or thicker till it's cherry red.Throw the shim pack on it,push them down like a hamburger on a grille,and watch the thin shims curl up and away from the others.I have had some modern shim packs though that this had no effect on.


      • #4
        Good ideas. I've always had trouble separating the packs, so I just sand them.


        • #5
          I've used a magnifying glass, then scrape the edge with a razor blade until a corner starts to lift up.

            torch works the best shims stay straight


            • #7
              I always found individual shims come apart easier when bending same back and forth because of their having no shear resistance between individual pieces.

              Similar to structural wood and/or steel beams carrying loads & Model A springs carrying loads ..... there is zero shear in centers of structural beams and Model A springs at the center bolt; however, shear and internal "sliding" forces occur further out at both ends when bending during deflection.

                The new shims of the past 3 years or so, are put together with a modern Glue. They are all but impossible to get apart with out heating to burn the glue out of the packs. I use a small propane torch to burn the glue away, and a small needle nose pliers to hold them with. Where the pliers holds the shim, the pliers jaws protect the glue, and will keep the pack together, if desired. Do it very slowly, only takes about 10 seconds, or less. When the flame stops, from the Glue burning, your done.

                The shims that come as Main, or Rod shims are normally of .003, and .002 thousandths increments.

                  Thanks Mr. Herm for the heads-up to be aware of modern shim glue.
                  Last time I bought shims was 12 years ago.
                  Also, I'm not the swiftest person at our now "Mandatory" Home Depot Self-Check-Out Lines either ...... going through is beginning to resemble a sort of Obsolete Feeling.

                  We still have both, self and standard. Usually there is an employee in the self stands that will gladly help you every step of the way if you walk up and ask them. Some HD stores don't have self checkout, and more of the Lowe's don't have self checkout. A lot depends on the area the store is located. Same for spray paint cans, taggers areas are locked up and no self checkout.

                  Everything goes well at our HD until the military card is shown ..... at our HD they have to verify same & enter this card acceptance at a different register.

                One thing I learned and now do is a little trick Mitch mentioned I always used a lighter on heat shrink tubing never did use a heat gun until Mitch mentioned it that thought never ocurred to me and now that is the only way i do them.

                One thing I do do is when making wiring especially on my a I wire wheel brush the heavy plastic off of a terminal so it is bare put heat shrink tubing on...

                Hood protection

                A tip for the anal

                I make these little tubes from cutting down a heat shrink. Then place them on the hood hold down. This protects the paint from metal to metal contact. If ya heat it with a heat gun it will never fall off. Either way works heated or unheated.

                Tip #1

                When soldering SPLICED wires, hold the iron UNDER the wire & apply solder to the TOP!
                Most common soldering problem is NOT enough HEAT !
                Use ONLY Rosin Core Solder!---Acid Core Solder turns it GREEN!---GREEN is only for MONEY!

                I have seen the heat shields vendors sell and kind of thought they would be nothing more than rattling vibrators under the car. I did something different that we used to do on sprint cars they make a high heat wrap napa and o reilly have it and I wrapped the entire exhaust and muffler with it it is help in place with little stainless ties i would post a picture but it is under the car and would...

                Handy Battery Jumper Wires
                by Tom Wesenberg
                I usually make up clip leads with alligator clips on each end, and usually make up one wire at a time. Sometimes you need to power an item right off the battery or from the large nut and stud at the starter switch, so I picked up up a pair of battery clamps and a set of 4 alligator clips at Menards for a couple bucks. I used an electrical cord from the surplus store for another 95 cents, so I only...

                As some of you know, I was boring and polishing stock A manifolds for B carburetors. I lost my bore plug, locater pin which I didn't consider really satisfactory. I don't have the access to steel I once had so I have to improvise. I was wondering what I had around that I could use when I saw an old sector gear that I missed on my last scrap drive. Aha! Sez I, and tried in the bore. It fit rather loosely,...

                George Miller question.
                by BNCHIEF
                George when we were down at the workshop I got a block from Mitch which you magna-fluxed and said it is a good block. It has some studs in it which I need to remove. It is only the studs and I certainly do not want to break them off. I can tig a nut on them if that is a good idea but I thought I would seek some guidance from you. Thanks

                Fixing a Bad Starter Repair
                by Tom Wesenberg
                A club member's starter quit working the other day, and it was easy to see why. Someone had worked on the field coils or starter contact, and did a poor solder job. They cut the starter field wire short of the contact slit, and left some of the old winding still soldered to the contact. They then tried to solder the windings to the short strap, but didn't use enough heat, which resulted in a cold...
