chassic buildup?

[John Pol]

You guys when you do a Pro Stock,Pro mod or funny car and scratchbuild your frame. Do you make up a jig for the chassic? If so how do make your jigs? Also do you draw the frame out first and put it on something to get it right? Any help would be great want to start scratchbuilding my chassic for my drag cars.

If you are going to build a chassie from scratch with front and rear suspension i would say that a jig is a must.

Because it is very difficult to get the wheels in the right place, i have a topic in this forum called "Duster pro mod build" that you could look at.

It is not so much yet but you can see a little about it.

For the first you should mock-up the body height from ground and then the wheelbase you want.

Then you have to measure a lot inside the body and start to build up all the distance between ground and the lowest part.

You can use some clay to fix the wheels and some rods between the body and the ground.

then you could lift off the body and start to take measurments of the wheelbase mock-up And ofcourse do a drawing of your chassie if you want.

I´ll hope you understand my explanation,take a look at my topic and i´ll think you know where you start the operation.

you probably do want to draw it out as much as possible . For a quick jig for the main rails you can use 2 adjustable squares just add the second adjustable part to the ruler part so you have two facing each other it should keep them straight .

My process is detailed in post 7 of this thread:

The chassis I use is based on the Eliminator frame from Chris Alston's ChassisWorks. Similar frames are found at Quarter Max Race Cars.

Someday I'll finish that Merc...

Although I dont use a jig, you can see how do do most things at the link, dont know if it can be shown much simpler than that
