    We race Mazda MX-5s in Northeast Region SCCA sanctioned events. On race day we have various alignment tasks to perform; often under less than ideal conditions. We have to adjust our corner weights and fine tune the caster, camber and toe-in to optimize our cars for track conditions. It would be nice to have a flat, level and square reference surface on which to put the car and set up our string-boxes etc. While what is currently available is very good; they are also very large and awkward to transport. Could I use an Eli-Table for this?

      Dear Gary,
      The beams and rails are designed to create a planar (flat) reference, but flat is not necessarily level and square. Moreover the standard legs (unless you use a lot of them) probably won’t support the weight; and then you’d have to find a way to get the car 30”+ up in the air.
      That said, I do believe that with a bit of ingenuity and care you could devise something that will meet your needs and be extremely light and portable.

      You would need to start with two sets of 5 short beams and 8 rails. No legs (but keep a few pairs on the back of the trailer so you can re-purpose the beams, legs and plates for pit tables, picnic tables etc.)
      Create two legless Eli-Tables of a suitable length. You’ll have to work out the exact arrangement based on the car’s wheelbase. Interleave the rails (3 rails, 2 rails, 3 rails) across the five beams so that each group mates with at lease three beams.
      Next you would need four ¾” ply “plates”. One front, one back (under the tires with enough extra to set up your string boxes.), two runners, and an “X” brace. You can probably get the plates out of two 4×8 sheets of ply.
      The “X” wants to be two suitable lengths of 3/8” x 2 aluminum bar stock. One length padded up at the ends so that the upper brace steps over the lower when installed. Drill holes dead center in the two parts and fasten them together with a loose bolt; this way they’ll scissor together for transport. Drill similar bolt holes in the ends of the brace parts. All these holes want to be carefully located so that when in position everything lines up correctly with the bench dog/bolt holes in the appropriate rails. All the holes want to be a skosh oversize to ease assembly.
      The front and back plates want to be bored with suitably located holes so that they line up with two points into each of the six rails they cross (front and back). The runner plates also want two points into each of the two rails that each runs along. The plates want to be cut square (don’t rely on the factory edge) so that they all fit together snug when square to one another. You will have to notch out the inside corners of the runners (or the front and back plates) to allow the “X” brace to bolt into the innermost rails where the runners and back/front plates meet.
      Set-up is pretty straightforward. Assemble all the parts together and bolt finger tight. Using your tape measure, a lump hammer and the 3,4,5 right triangle make all square and honk down on the bolts (flat washers plus split or star lock washers would be a good idea.)
      So, now you’re flat and square. Shim under the beams, checking with an 8′ mason’s or laser level, set up your string boxes, do your alignments/corner weights and; you’re off to the races!
      You could gussie this up a bit if you want. Rippings fastened to the plates to guide the tires, stops so you don’t run the table, other kinds of alignment hash marks etc. and a pair of mini ramps to get you up the 7-3/4” you’ll now be off the ground.
      For expanding the horizons of Eli-Tables. I’m sending you a signed and inscribed print. May all your days be racing days.
      Eli
