  • Two Ps (with pods)

    With the vacuformer, I finally got around to putting windows in my 3D versions of the 312P.
    Absolutely gorgeous car, one of my personal favorites.

    I am new at vac form windows, so as first attempts they aren't great......but it's a huge improvement over no windows and at least I am learning. I also have a buck to make the headlight lenses, so those are still in process. Interiors are in the plans for today.

    #18 already has run.....3D chassis and Hawk motor. #19 will have wider tires and similar motor for our Fly coupe class.

    I have a resin version of the Aurora car....these gave me some courage to do that one someday.

    Finally got the 312Ps done. Headlight covers were a learning experience, but the last pair didn't come out too badly.

    My own printed inserts finished them off. Basic, but raceable.

    #18 has my normal chassis with D3D pod.
    #19 is running a prototype printed SW chassis. Click image for larger version

      are you using pla for the buck and if so dose the heat affect it.

  • #3
    Yup, I made the bucks from PLA. It works fine if:
    1). The base has some thickness
    2) The parts are allowed to cool a bit before removing the buck.

      Good looking stuff Paul.

      I have been making bucks from resin. I do a rubber mold of the area, a clay model or whatever is the easiest thing to do. I pour resin and sometimes sand or polish a little. I set the buck on anything that raises it about 16 inch or so above the bed of my vac (Mattel). I heat the plastic with a butane torch to get it soft. You have to be careful to not get it too hot, too quick as it will blister. I already have my shop vac running connected to the bed, then pull the plastic over the mold and if it doesn't such down tight at all points, I use the torch a bit more and then it pulls down really tight. Sometimes the windows pop right off. Sometimes I take an Exacto and make some splits to let the window spread and come off the buck.

        Hey Chappy,

        Firstly the cars look great, would love to have them running on my track.
        Great work again with the vac-former, glass & head lights look very nice

        Cheers

        Matt,
        I agree. Some headlights, like the 917-20, are pretty complex curves and are difficult to model with my sad CAD skills. In those cases a resin or clay model works better.
        Others are easy enough to model and print, and some sanding afterwards makes a smooth buck. The PLA works fine if the base is 3-4 mm tall and you wait for things to cool before separating. The PLA does get soft and a thin base will twist on removal if you pull when everything is still hot.

          Paul, I have been surprised the resin doesn't get soft from the heat. I know I fix a lot of resin bodies with hot water! I figured the heat of the plastic would maybe cause it to stick or soften the buck, but I guess it doesn't stay how long enough to effect it. Handy to be able to make vac stuff. I found I could also make interiors to fit smaller sports cars or Indy cars.

            I think it's the heat sink effect. The heavier thicker stuff doesn't move, but a thin base plate can be bent and deformed when warm. A thicker base stiffens back up more quickly when cooled.
            Vac formed interiors are easy, without the head. I just go ahead and print the interiors too.
