    Exceptional work.

    I particularly like the way that your pictures of the inner fender wells progress from "bag of hammered assholes" directly to "finished perfection" with no steps in between. lol

    Like sheetmetal magic, it is.

    the only steps that are not pictured is planishing out and then turning the edges. hard to get in progress pics of that stuff since i am in the shop alone a lot of the time

    @cornfieldcustoms Great lighting and camera work. You make it look so easy. Are you going to be sharing streamliner photos as you progress it?

    Wasn't complaining or critiquing, more like expressing wonderment at how such an ugly mess suddenly turns into perfection when properly massaged.

    Your work speaks for itself man, ain't got nothing to justify to a chip maker like me.

    Had some visitors at the shop this week, John Glenn and his father (from Anderson Auto Glass, Anderson SC) came up so we could use the truck floor dies we made for the effort to modify the ribs on a 2009 Ford replacement floor for use in a 1966 Ford they are restoring.

    [​IMG]

    [​IMG]

    [​IMG]


    The new floor has flat area provisions for a fifth wheel bracket and the original floor in a 1966 has full length ribs front to rear. We needed to modify the flat areas to provide these full length ribs. James McKenzie also stopped by to help in the activites.

    quote: (John Glenn) I didn't go into much detail about this earlier, but the F250 bed floor had four flat areas for a fifth wheel hitch that looked really out of place for use in a '66 F100. I contacted Robert (MP&C) about having him make dies for his Lennox to reshape those spots into continuous ribs to look more like the original bed floor. I sent a sample so he could make dies a while back, and yesterday our schedules finally aligned so we could work on the bed floor.
    [​IMG]

    We started by gas welding plugs in the four holes that won't be used on the F100. I didn't want to weld those with a MIG at our shop since the weld would be more brittle and would probably crack during the reshaping process. Gas welds are much softer and more workable.
    [​IMG]
    [​IMG]
    [​IMG]

    The welds were smoothed down and the flat areas were pre-stretched in the english wheel with a bit of guesswork as to how much we should pre-stretch.
    [​IMG]

    Then into the Lennox to add the ribs. This was done gradually in multiple passes, adjusting the depth of the dies after each pass.
    [​IMG]

    Slightly reworking the dies to gain more rib height.
    [​IMG]

    Finished ribs. These are hard to photograph so I stripped an area with the two new ribs in the center of the outer original ribs to show the matching profile.
    [​IMG]

    James (duallyjams) dropped in to hang out for the day, it's always good seeing him! He was a big help and also shot vids of us working.

    For anyone using a Lennox, Baker, Tru-Edge, etc style machine, the largest drawback is that they have limited position for the tooling actuator lever when compared to the Pullmax.. So there was some discussion online of making the Lennox style machines to function more like a Pullmax (the multi-position lever settings, not the oil leaks ;) ) I posted up a "sketch" of my thoughts on the subject … using a bolt-on bracket that would use existing hardware..


    [​IMG]


    [​IMG]


    [​IMG]


    Mike Wagner (Cornfield Customs) has better capability in machinery and cutting parts, and took it from there to make a prototype bracket using the bolt on design, and a slight modification of the original actuator lever (includes welding)

    I got my copy in the mail today, so it starts with bolting on the bracket and marking the pull pin location holes onto the original actuator. Then this is drilled up to a 1/4" hole, then a 1" hole saw is used to add a concave radius to match the pull pin housing, for a nicer TIG weld..


    [​IMG]


    Housing TIG welded in place....

    This should save quite a bit of adjustment for the next set of louvers...

    I can't compete with some of the stuff Robert does. I did have to make a LH Quarter for my '53 that was both rewarding and quite successful.

    Here is the rear section of the quarter as well as the ruffed in complete panel.

    Made some model a sedan inner wheel wells the other day. Working on the rest of the quarters in the next few weeks 24CA02A8-D01E-4983-BCF6-171BC3995564.jpeg 764D2AF4-2CB3-4D77-BBE0-83B6DC1B0928.jpeg 125A2D2F-C743-444B-935F-73C545372020.jpeg

    Did you use any form to hammer over?

    No, just hammered into a lead bag and cleaned up with the planishing hammer

    Question to the metal bashing panel, Does anyone have dimensions of a P5 Pullmax? Looking pretty serious at one and wondering some actual dimensions to see if I have the space. I can't find a spec for weight either. I have found 2 weights that are way different 1600 and 4000 pounds. I can lift 1600 but will have to get heavier equipment if it much over 2000 pounds

    I had one but sold it because it was too big for my shop.1600lbs is what I came up with for weight,the throat depth is about 42 inches my shop was 24'x32' it just took too much space which meant no room for cars hope this helps

    Wow, what an impressive showcase of skills....especially to us mere mortals!

    Some great inspiration!

    So someone I went to high school with many moons ago had a V8 Plymouth Arrow, tubbed, while in high school. He caught up with me a few months back, and had some work he wanted done on the hood. Yeah, still has the car almost 4 decades later.. He said he wanted a more professional job this time..

    IMG_6294.JPG


    He had bought an NOS hood for it some years back, so at least he has something solid to work with.. He said the metal flopped a bit, so I thought we'd make some new bracing on the underside while we were at it. Here's the phenolic dies made for the Lennox to form the new bracing..
    IMG_6202.JPG


    A test sample...




    ...and a test fit

    IMG_6205.JPG

    Next, the bracing we wanted needed to go around the bigass hole, and some of the existing brace needed removing.


    IMG_6229.JPG


    IMG_6231.JPG

    Our new brace designed to go around the hole... cut in the flat and run through our dies..

    IMG_6209.JPG

    And here's about where it goes...

    Rather than screw up one of the last remaining NOS hoods, let's do a test sample first.. To strengthen the opening, we'll add a 1/8 wire edge protruding upward to help keep things out.....somewhat. Here's our new dies for the 1/8 wire... This is the "inlet" side...

    IMG_6245.JPG

    Side view shows the ramps to add the joggle

    IMG_6246.JPG

    output side...

    IMG_6247.JPG

    We're using a 22 x 22 piece of 19 gauge for our sample, and folding a 5/16 flange, which needs a bit of stretching to keep things flat. so a rounded hammer on the top of the stump adds a bit of stretch, then a linear stretch hammer and dolly to fold things over..

    IMG_6249.JPG

    with the flange folded, the sample is run through our dies to form the joggle

    IMG_6252.JPG
    1/8 stainless is formed, sized, and TIG welded to form a continuous ring. Then it gets laid in the channel and the flange staked over in various spots to hold it in place using the linear stretch hammer..

    IMG_6253.JPG
    Hammer action...



    Finished sample...

    IMG_6257.JPG

    And checked to the brace...

    With the practice behind us, lets see what we can do to this hood. The outer circle is the mark for our fold, or opening size. The inner circle is the cut for our flange..

    IMG_6297.JPG

    Getting our tin snips started...

    IMG_6299.JPG

    Hole cut with no filing, no sanding, and absolutely no metal "splinters".

    IMG_6302.JPG


    If you have issues with tin snips, I recommend Bill Gibson's tin snip video...



    Next, on to the underside. We have these ruffles where the old structure was cut out that need to go.

    IMG_6308.JPG

    A piece of 16 gauge was used as a heat shield and using some heat and the barrel end hammer, reshaped the offset back to flat...

    IMG_6312.JPG

    IMG_6315.JPG

    IMG_6317.JPG

    Two down, two to go...

    You say you hammered the deep draw pockets into a shot bag and planished on the full size blank? Seems like it would thin drastically and split at that depth.
