    Hey,

    I'd like to hope that anyone who's considering the alteration of a
    '55 Chevrolet quarter panel would be in possession of top weld-
    ing skills, or at least have sense enough to find someone who
    does. The quarter on a two door, any two door, is no place to
    learn how to weld.

    i did a 55 hardtop last year with nomad quarters , look good but diff from the usual round look we usually do. and they were a grand each ...here are pics of the nomad and the radiused ones on the gold car done with 1`/2 inch tubing welded around it

    I would make a paper pattern of the radius/opening with reference lines to the bottom edge of the body and any thing else I could measure to. Then transfer the line with transfer paper or pounce to masking on the body on both sides with the one pattern.

    Going off the center of the axle is great if your springs have the exact same sag and the axle is dead even forward and aft. Also cuts down on the chance of different radiuses side to side (operator error)

    bend some emt conduit to the desired radius

    mark this on the panel on the inside of the radius

    cut the inner from the outter panel

    trim the outer to the mark

    trim the inner one inch lower than the outer

    cut relief cuts in the inner every two inches front and fear from top center mark

    tack weld, or braze, your emt to the outer panel, outside to leave a small flare when finished

    bend the inner panel tabs outward to wrap around the emt. trim as necessary so as not to extent past center of conduit.

    weld tabs to conduit

    finish welding, or brazing if you prefer, everything solid

    smooth with body filler of your choioce. lead or plastic

    prime and paint

    this method will give you a vintage look, seal you panel, and keep the panel strong.

    good luck with which ever method you choose.

    You could use 3/8" solid square stock. This allows you to make a hammerform that can be welded to, or removed when you are finished. If you weld to it, the weld can be around the corner from the rest of the sheet metal of the quarter, making warpage less likely. Bend to the curve you want as seen in the attached pictures. You can pound the metal over a gap, or for slightly finer tuning, pound over a piece of wood. Weld temporary supports to hold the hammerform steady, clamp the sheet metal and gradually tap it over with a hammer going back and forth until is all the way over against the hammerform. I usually put a slight amount of front to back curve in the piece before making the wheel opening curve. There are simple ways to remove too much curve that I can show if you like.

    Heres some shots of my 57 radius job. I used 3/8'' solid rod for edge. once the ride height is set i traced the radious with a home made compas stuck in the ribbs of the piecrust slicks. In order to do this you must rough out the size first . No need to make template. Also lip is existing sheet metal bent and hammered .

    Volvo front fenders 200.00 at the local salvage yard. The curve of the volvo fenders fits the body perfect. A little cutting and welding and there you go.

    Thanks to everyone that posted on this thread. My rear quarters were a mess and I needed some ideas, this one worked for me. Pooch

  9. I done a number of wheelwell modifications back in the 1970's. The preferred method at the time was #1--cut out the opening. #2-Bend a peice of thinwall steel electricians conduit around a tire (by hand) untill you match the cut out radius. #3--position the bent conduit on the outside of the quarter panel surface so that the cut out quarter falls in the center of the conduit. #4--mig all around from the inside (this requires blocking car up, removing wheel, setting in the wheelwell and covering crotch and legs with a peice of leather to keep from burning to death) #5 moving back to the outside and cutting a number of peices of sheet metal about 3" x 2 1/2" and welding to the outside center of the conduit and to the side of the quarter panel.---work your way around, tacking as you go. The fact that you are welding in a number of small peices of sheet metal will let you follow any compound curves in the dogleg area. #6--weld up all the gaps and grind everything smooth. #7 Fair everything in with "Marglass" which is a waterproof, glass fibre entrained filler. #8 grind to "close" with 6" body grinder. and #8--Finish with normal body filler and boardfile smooth. This gave lots of reinforcement to the cut out quarter panel, left no sharp edges, made everything look "factory", and added a small flair.---Brian

    1. Get a friend to help
    2. Get baseball bat
    3. start car up
    4. Force baseball bat between quarter panel and rear wheel.
    5. get friend to hold baseball bat
    6. Put car in gear
    7. drive car very slowely (while rolling baseball bat with the wheel) until baseball bat has made it all the way around the wheel.

    And now you have radius'd wheel well

    I think if you have a fiddy six or seven it is cool to keep kind of the original swept back shape of the wheelwell. I had a "axled" 56 back in the 80's. the original wheel well lips were cut off and repostioned higher .. right below the original Bel Air side trim.

    the idiot that did it (no, not me) cut them out, then brazed and bondoed them back on. it looked cool before the cracks started.

    those Volvo lips are plentiful in the junk yards since they made pretty much the same car from the early 70's until well into the 80's and maybe beyond that
     
  17. I used quarters off an S-10. Bought just patch panels, not complete quarter. Had to shorten them a little to get the right look.

    Get a tape and head to the wrecking yard. Theres gotta be plenty of stuff that will work ,van,truck. Who knows a 89 buick might be perfect 90 van, hell anything just finy something "you" like and do it.
     
  19. Thanks for posting this! Personally this is the ONLY way I would radius rear wheel wells.
    I have to ask, did you end up doing any welding after you were done?

    Back in the day, in Ohio, we would just cut on the line made where the rubber seal on the inner fender rusted the quarter out.
     
  21. I put an ad on "Craigs" locally for a pair of 240 Volvo fenders...in less than 2 weeks, I found a pair, already removed, for $30! I recommend other HAMB members checking their local CL for cheap 240 fenders, if that is the route you wish to go. Local yards wanted $75 each and up.

    When i cut mine I also asked (How do you do it?) I also didnt want something that looked different from what they did back in the day. I wrote a blog on my build up different styles from way back when. Check it out. I have a photo of my 55 it can use 31x13.5 slicks in the rear and they only stick out 1 inch past fender on a 15x10 mags 3.25 back spacing on a 57 chevy rear. ;)

    Nope, just sprayed some satin black around the cuts, about 1/4-inch wide, and called it good. I wanted it to look the way most street machine '55s with cut quarters looked back in the old days--just a cut radius, cleaned up and trimmed with black paint. Low buck, like most of us were when we were young street racers.

    the volvo fenders look ok but i personally dont like the way they get a bit straight toward the back of the wheelwell. the car does look sweet though!

    Oh I got a little antsy about cutting my '55 but then my buddy Brad, who did the cuts, said that I had to do it. It's the look I knew I always wanted on a '55 if I ever got one and so when I got one I had to do it. (Damn that 1964 Revell '55 model box art!!! Screwed me up BAD--PERMANENTLY.) I hung the two cut-out pieces, with the cut-out trim in place, on the garage wall.

    Bringing this one back to life.
    I am getting ready to do mine.
    I'm using a little old school and hi tech just to double check myself.
    I laid the thing out old school and from the centerline of the axle, to the height I want the top of the new fenderwell I get about 16 1/4
    That makes an overall diamater of 32.5 inches.
    I had a CAD drawing that was a 31 inch circle, 15.5 radius but there was no way to position it and make it work. It seems that the 16.250 radius will do the trick.
    I should know tonight and I'll update with pics when I have this thing all triple checked.
