Re: Chassis Connections

In the past couple of years I've developed a pretty cool method for putting our frames (chassis) together.

Basically we have our own gussets made out of ~.060" aluminum and make them in two varieties, 'T' or 'L' (this is usually done by waterjet, and we can get the parts for around ~$1/piece). The Ts have 4, 1/8" holes and are 3" long while being 2" tall. The Ls are 3 holed around 2" X 2".

We pretty much use 1" box beam for all of our framing needs. This then allows us to put a simple hole pattern of 1/8" holes 1" apart, and 1/2" from any edge to rivet our frames together. For most applications the riveted frame is strong enough as is. However, the nice thing about doing it this way is that you have created a welding jig once riveted. If you then want to go back and beef up certain or all joints, you simply just start welding. The gussets will hold the frame extremely square, especially if you put the holes in the frame members on a bridgeport or mill.

I'll try to dig up some pictures to make life easier, but in the meantime if you have any questions feel free to ask.

EDIT: Picture found
