    how about 1100? A friend has told me that this is common also.

    Aluminum Material for Dash

    I am going to build an Aluminum dash and I am looking for the correct Aluminum material to order. It needs to be soft enough to work with and be weldable. Most likely it will be 22-20ga (.029"-.036"). Thanks

    welding 4130 and anealing

    Rich - Thanks for the reply. You are absolutely right. The tubes are smaller than 1/8" wall...always. Question #1 - What is your source for this information? #2 How do you know the tubes under 1/8" wall will cool to the normalized state? This seems to be the exact reason it...

    welding 4130 and anealing

    After welding 4130 tubing (for a roll cage), I know a guy, (a very reputable guy) who is dousing it with WD-40. I know you are supposed to anneal a 4130 joint but what does the WD-40 do? He does not anneal the tubing after spraying with WD-40. Before you say he is doing it wrong, his work...

    4-link

    If you do that, the shock will be leaning over too far at the top of the stroke (about 75 degrees). Usually you don't want the shock to lean past 30 degrees to remain effective, and consistent through the stroke. That's why you mount them on the trailing arm.

    4-link

    Lean it where? into the cab? Can't lean it backwards, need longer shocks for that. What do you mean by a bell crank? Can you explain or show a picture?

    4-link

    It's not a trophy truck, it's a pre-runner. The bed is shorter on the supercrew than on a supercab with a short bed, however the wheelbase is the same. To add to the difficulty, the transfer case takes another 18" out of the drive shaft length from a 2wd. Most of what you will see are...

    stress relieve 4130 tube

    brittle enought to where you better HT the tubes all around your body (especially the upper joints around the roof and top corners)! Hopefully you cut holes in the floor board so you can drop the whole cage down and hit it w/ the torch. It's a lot of work, but it could save your life or the...

    stress relieve 4130 tube

    check with the local welding supply and get some heat sticks for the proper heat range. If they don't have them, I'm sure they can direct you to the right place. The stick will start to melt when you get it to the correct temp. I've never done it but I've heard that is how it is done. By the...

    4-link

    I am looking for design info on a 4-link. I have a few books but they are mostly for road cars. I am building a long-travel rear suspension for a newer Supercrew. In particular, I am looking for maximum u-joint angles and amount of anti-dive others have worked with. I want the back to drop...
