    Cheap, fast & good - here's one case where you can have all three!

    A slapper is a really handy tool for planishing and metalfinishing panels, I understand that you can buy them, just not sure why you would?

    Just grab an old leaf and mark it out (that's about 14" in the pic - working area about 7" long )

    [​IMG]

    Have at it with a slim disc on a small grinder

    [​IMG]

    Grind off the rust - take care not to gouge it or dig in with the edge though (perhaps I should have swapped that sanding disc out earlier:rolleyes:)
    [​IMG]

    Pop it in a vice or clamp it to something and heat it for the first bend

    [​IMG]

    Bend it about 60 degrees or so and heat about 3" further up the handle before bending this back to parallel with the working face

    [​IMG]


    Allow it to cool down slowly ( you may want to bury it in sand or mica, but for this application I find air cooling to be fine)

    [​IMG]

    Run it on a belt sander to get it all smoothed out. Right now you may be wishing for a late model O/T leaf spring - this piece of '48 one keeps it all traditional and HAMB-friendly but the trade-off is a little more pitting to deal with :D

    [​IMG]

    You could just add tape or a piece of rubber hose at this point. I went high-tech and epoxied on some scrap wood

    [​IMG]

    Rounded it off to a comfortable shape with the trusty Makita
    [​IMG]

    Take care to kill any sharp edges that will end up marking your panel. Same goes for surface imperfections - they will imprint onto the metal you're working. Start on the belt sander and then do the final blending with a DA

    [​IMG]

    Some folks will polish this with progresively finer grits on the DA to a mirror finish. The way I finish a wheeled panel, I like a little surface texture that shows my hit marks on the already shiny metal so I stop at 120 grit.
    Some string bound around the handle and call it good

    [​IMG]

    All told there's about 40 minutes in this (could have saved 15 on the handle) and maybe $3 materials. Couldn't even drive to the store for that.
    This way you can make up a couple with different sizes, radii and weights.
    Nice to have a good balance to them - this one could do with being about an inch shorter or have a little more weight in the handle.
    The only other thing to think about is making sure the kick up is high enough to keep your knuckles out the way of the metal...

    Nice tool Barry!! I have one I left the jog out of and left the spring arc as is. It works great for the top of those '36 fenders I did.
     
  6. That turned out great!

    I did the same but used an old file, works great. Just as good as a bought one.
     
  11. I'd like to slap my ol' lady in the ass with that. Nice job.

    Cool tool, and home made too. Now we need a tech thread on the proper use.

    Thanks!

    terryble, was this just a coincidence, or is your ol' lady kind of a freak?

    Great tool! My Buddy Hamber Bob made 2 of these slappers from a C1 Corvette spring I had a few months ago. I also purchased a "shrinking disc" as well and I'm very happy with the success I'm getting "slapping and shrinking".

    Many of the tools we use are not HAMB friendly!
