i built a big frame table today out of a junk forklift mast. im wanting to set up the american stamping rails i bought. there seams to be 3 different planes down the sides of the rails. one where the rear crossmember is , one where the contour on the side is, and one at the front axle. also ive printed out a frame diagram from wescotts i believe. and with the body mount holes in the right place the front and rear of the frame are about an inch wider than they should be. i figured i would make up some spreader bars for the front and rear even if they are just something temporary. and then what use a sqare off the table for the center of the frame front crossmember will be model a rear crossmember is one i had bent out of 3/16" flat accross and i had some 1/8" c-channel bent up to build the x-member ive been getting a lot of info on things from the techarchives that is sort of getting me ahead of myself and boggling my mind. thanks for any help.
