    The front suspension on the '64 is just about complete. I was loaned
    the coil spring compressor from the local auto parts house and
    promptly broke it. Not really my fault. The block was stressed and
    the threads on the bolt were already flat. Any of you ever make a
    spring compressor? I have a few ideas but they will be hit and miss
    until I find something that will work. Thanks for any help.

    Your friendly neighborhood Jarhead

    [updated:LAST EDITED ON May-07-03 AT 12:26 PM (CST)]Hay, 71,, I can't answer your question about making a spring compressor, BUT...

    You can do the spring removal without a compressor. Need truck up on jack stands, (Duh!), and a good floor jack.
    Before starting, tie off the spring with a sturdy safty chain and secure it with an equally sturdy U bolt.
    Compress the spring by placing the floor jack under the a-arm of your choice and rais it up. Then, remove the cotter pin from the upper and lower ball joints and back the castle nuts off an inch or so. Don't remobe them yet! Then, S L O W L Y lower the floor jack. If the hub has not broken loose from the ball joint mounts, grab the mini-sledge and guve them a goo wack. The tension in the spring should break them loose with no problem. Then jack up the a-arm again, and remove the lower castle nut. Once again, S L O W L Y and CAREFULLY lower the jack until the lower a-arm falls free. The spring will then fall out after you remove the chain.

    Installation of the spring is a simple matter of positioning the spring in the upper pocket and, using the floor jack, raising the lower control arm up to compress the spring and mounting the hub on the ball joints. Get The Castle Nuts Back On FAST !! then use new cotter pins and she's done.

    Hey, d. The springs are already out. Kinda funny, that. I was taking
    all of the nuts off the upper control arm and thought maybe I should
    move to the side just in case the spring let go in a violent manner.
    POW!! Guess I was right. We did the other side with the control arms
    secured until I had the nuts off and then let the pressure off
    s-l-o-w-l-y. Live and learn I guess. The shop manual I have shows a
    heavy duty compressor that the Chevy mechanics would have used. Much
    different than the one I borrowed.I may see what the local Chevy
    dealer uses for stuff like this. As a friend of mine says,"If you
    ain't bleedin', you ain't workin'!"

    When I was much younger, I saw a neighbor make that same mistake and let a spring have it's own way. Car was parked inside a garage. It exited it's mount in great haste on the left side, bounced off the wall, richoceted off the ceiling, hit the opposite wall, then the floor and bounced up and destroyed the "right" fender ! A perfectly executed four bank shot.... As you can imagine, everything it came in contact with was vaporized.... SCARY !!!

    Bwahahaha. Bwahahaha. Well, guys(and wimmens if there are any out
    there), I am the proud owner of a complete front suspension. My idea
    for a coil spring compressor worked exactly how I thought it would.
    Two pieces of 1/2" steel plate 4"x16". Two lengths of hardened 5/8"
    all thread because they didn't have grade 8 bolts as long as I wanted.
    For all purposes, the all thread is grade 8. The nuts are grade 8.
    One bag of 5/8" washers just for kicks(only used a few). 5/8" holes
    drilled in each end of the plate about 3" from the outside edge and
    centered. One plate on top of a 2x4 block on top of the upper ball
    joint bolts and the other underneath the lower control arm and plumb.
    The kid on one rod and me on the other. We tried to compress at the
    same pace so as to get the same tension on both sides. It actually
    worked better than I had hoped. Spring went right down, no problems.
    Upper ball joint stud travelled right into it's hole in the spindle
    and away we went. The only issue was that as we started the process,
    we had to keep our foot against the lower plate because it wanted to
    travel because of the angle of the lower control arm. As soon as the
    lower control arm leveled out a little, the problem was moot.

    My father and I were critiqueing my engineering abilities and he
    thought that 3/8" plate would have worked fine. That may be true. I
    wanted absolutely NO flexing so I used the 1/2". I wanted ALL of the
    effort to go into the compression so we could focus on that. My 'kit'
    ended up costing me about $50. The plate was the most expensive part.
    It would have been about $30, but I had to buy a $20 drill bit.
    You may want to stick with 1/2" rod. You probably already HAVE bits
    up to 1/2". Save you some cash.

    *DISCLAIMER* This setup worked great for me. If you like this idea
    and want to use it, please do so and good luck. If you should have a
    failure and the spring flies out and destroys your garage and puts a
    dent in your skull, don't blame me. You are 100% on your own if you
    want to try this.

    PS: I love it when I'm right about something. :D :D
