    Default Mid-Engine Sandrail Project

    Well after about 15 years of wanting to build a sandrail I finally pulled the trigger and commenced my build. I started with one that I purchased that was damaged/wrecked but had some nice parts on it. I cut about 90% of the original car away and fabricated basically an entire new chassis from 1.5" DOM tubing. I am making the chassis wide enough to be comfortable whereas the original was built for a very small individual and was not even comfortable it I were to have just repaired the damage.

    I was going to widen the bench seat that was in the car when I widened the chassis, however, after meeting a gentleman at the dunes a couple of weeks ago and sitting in his car with suspension seats that totally changed my mind. Suspension style seats looked like the way to go.

    I have built several street rods and muscle cars as well as a few custom ATV chassis and felt as though I was ready to tackle a larger all tube chassis. This is my first sandrail chassis and hopefully there will be more to follow. I am really enjoying this build, more so than many of my projects as of the last few years. Thanks for looking, Mike.

    This picture is of the majority of the original car cut away and the new chassis coming together while sitting on the frame table that I had just built.


    This picture is of one of the joints where I joined the new tubing to the original. As per NHRA specs the tube must be at least one and one half the diameter of the tube in either direction of the seam. Must have rosette welds on either side of the seam approx. 1/2 the diameter of the tube from the seam and the inner sleeve must be at least the same wall thickness as the outer tube. NHRA also recommends leaving about a 1/8 inch gap between the two tubes so when welding both tubes and the inner sleeve are all fused together properly.


    This is a view of the rear with the new outer upper and lower main rails bent, fishmouthed and tacked into place.


    This is a picture of one of the welds on the rear crossbar.
