I just thought that I would submit the first big welding project that I have ever done. It took me 4 months to design and 5 to build. The rear is made from 1 1/2 x 1/8 square tubing, the arms are 1x2x1/8 and 1 1/2 x 1/8 and the mid frame is 1 1/2 x .083. The b0dy is 20 and 18 gauge.
The front tires are 18x10x10 and the rear are 22x12x8. The engine is a little 6.5 clone but hopefully that will change someday.
I have two youtube channels where you can view this and some other projects... search youtube for (tully712) or (tmanskarts)
