I was asked to do an AMT 1/25 '68 Camaro Hardbody model kit to slot car conversion by a friend.

Since major body mods like flared fenders and widening of the rockers are planned, keeping everything square and most importantly the wheel wells concentric with the axles is critical.

With some fiddling, the Rgeo jig can be set up to fix not only the wheel base but to also provide a jig to hold the body at a fixed point.

With the wheel wells roughed out the body can be placed back onto the jig so front and rear body stops can be installed.
Also installed at this time are four body centering pins that fit flush inside the rocker panels .

Using this fixture, the body can be returned to a known position when taken off and on over and over again.

You can also use his body mounting jig if you plan on using pin tubes.

The thing is, once you start cutting the kit body and hog out the wheel wells, it's easy to lose your points of reference. Get them wrong and the wheelbase could be shorter or longer on one side!

In the past I've made custom jigs for each model from a piece of 1 x 4, but since the RGeo jig is so versital, figured why not put it to use.

Another project on the bench is this 1/24 Monogram Cobra. Going through similar steps as Camaro, adding flares and widening body.

With the jig set up to locate the body, you can use the tires as a reference to accurately enlarge and radius the wheel wells.

Roughing in the first flare using the tire as reference.

Initial flares are attached and "welds" are cooling.

Yes that's a great jig! I build everything from 1/32 to the 1/24 size hard bodies we race at BPR! I haven't found anything it couldn't do!! Hard to beat--lots of options with all the drill patterns Rick has.  Very nice jig--I use and recommend!!

Nice build Bruce--you Da Man with those big fender flairs!! :)

Thanks Tim!

Inner flares start as .020" evergreen Sheet Styrene cut into 1"x6" strips, twisted like a ribbon and placed under boiling water for 30-45 sec.

These thinner strips were glued inside the fender lip and serve as a base.
After they cooled, a scribed and laminated layer of .030" was added for .050" total thickness.
This top layer butts the outside of the fender creating a strong "rabbit" joint.
