Here are pictures of the mid 1960's Fiat twin engine dragster I'm building. I used to watch cars like run at strips all over the US. Apart from the gassers, these were my favorite cars. This is another 1/4 scale build as was the rat rod I posted a while back. I had to build some tube benders to do the frame as the ones I had produced the wrong radius. The frame is steel DOM tube as is the front axle. The engine blocks were mastered in styrene and rotary cast in urethane. The front wheels are 6061 aluim. The spokes are stainless Tig welding rods. I will use molded copies the M&H Racemaster slicks I made for the rat rod. Have to replace the heim joints on the steering as they are the wrong scale. The body is next. I think I will have to mold it as you will see most of the inside. The front axle and suspension parts will be chrome plated.

Oh, it looks like 1:1 frame and engines! I'm sure this one will be another great build, your Hot Rod was fantastic and this looks very good so far, too. Especially that link between the rear axle and transmission, looks very sharp.

Thanks for the comments, it makes it worthwhile to post the progress. Here are photos of the body construction process I used. I could have carved it, or cnc'd the master but this way suits the style that could have happened in 1960-ish if someone had built a chopped,sectioned, and narrowed fiberglass competition coupe body. The first coat of primer is on and now to chase all the rough spots. I will mold this and make a urethane body. I found a 1/25 scale Fiat body I had cut up many years ago which is in one of the photos to show scale.

This is amazing. The steel frame is great. How do you join the tubes?

Thanks guys.

 

Scott : the frame is put together with oxy-acetylene and 45% silver solder. I am going to try laser welding the brackets on a stainless steel  tube front axle in the next few weeks.

 

More photos you might be interested in. I made some tools from old hacksaw blades to turn little heim joints for the injector linkages. The third shot shows the removable section of the frame to allow the engines to be taken out.

I've finished a few more bits: magneto, spark plugs. and molded some wheels and tires.

I thought it a good idea to make molds of things that I might use for other builds like all the engine parts that are common, rear end etc.

The spark plugs are machined from stainless and white styrene. Boots are shrink wrap.

My good camera is kapooted....the one I'm using for these pics cost less than $100. :)
