A look at my Chassis Jig

[eugene13]

We finished a project and are going to be starting another so it's my project of the day to check our chassis jig for square, plumb, and level. as you can see, it's simply two 8 inch I-beams supported by three 6 inch square tubing "Bridges". The 6 inch square tubing foot of each bridge has two jack bolts and a sole plate, this is for inital leveling. The two I-beam have three sets of jack bolts and sole plates, these are fine tuning as are the turnbuckles

I am going to re-post this tomorrow, I have satellite internet, we have heavy clouds and snow so my pictures won't download.

Are you building race car chassis'?

Looks like, but I could certainly have used this for the replacement caravan chassis I built a few years ago. Initial plumb and leveling was done with cinder blocks and shingles on the garage floor. This looks MUCH nicer.

Yes, we will build you any kind of chassis you want, but we will be working on an IMCA modified as our next project.

The 6 inch square tubing foot of each bridge has two jack bolts and a sole plate, this is for rough leveling. The two I-beam have three sets of jack bolts and sole plates, these are fine tuning as are the 7 turnbuckles. There is one diagonal turnbuckle to adjust for square. The I beam was given to us by a local contractor who was cleaning up his lot, it was initially 25 ft long, I cut it in half and then with one beam on top of the other I filed the ends square and flush. Pic #5 shows the device for holding the rear end at ride hight #6 is the clamp that holds it to the bottom flange, there is a similar fixture for the front end. I use a Starrett #98 level and a straight edge to set this up, The last pic is of the level lit up with a lazer, pretty cool, huh.
