The
Project Begins:
I started the
project on November 12th, 2000 by removing the hardware for the
soft top and pulling the roll bar out.
I then stripped
out the seats, harnesses, console, stereo and cut the wiring for
the rear lights. After the tub was cleaned out, I crawled underneath
and removed the parking brake cables, gas tank and rear driveshaft.
The Sawzall was next to be deployed, and the tub was ready to come
off. This step was the hardest of the whole project, cutting through
my tub and it's 300 mile/two month old paint job. Oh well. If I
painted it once, I can paint it again. I selected an angled cut
immediately in front of the wheel wells to retain the fuel filler
stamping on the driver's side, yet minimize the complex panel fitting
on the wheel wells. Ten minutes later, the rear of the tub comes
off!
Once
the tub was off, I was able to remove the gas and vapor return lines,
cut the exhaust tailpipe and measure and mark the frame for cutting.
I selected the "flat" portion of the frame immediately
in front of the rear spring hangers as the location to cut. On the
CJ-5, this spot is parallel with the length of the Jeep, front to
rear, and minimized the complexity of the angles needed for the
splice into the frame. Now I was really committed!
At this point,
there was still plenty of daylight, but I really needed to reflect
on the work I had just created for myself, so it was off to the
showers. I would tackle this some more another day.
East Meets
West:
I had studied the OEM frame for a few days before selecting
common quarter inch plate as the material I would use to build rectangular
box tubing to insert in the gap between the frame sections. I have
a Lincoln Electric Weld Pack 100 (an excellent little 110v wire
feed welder), but had already determined that it's inability to
weld ¼" steel in a single pass with adequate penetration,
and it's light duty cycle, would make it an unacceptable solution
for the project. A friend and fellow FWD-FWD member, Mike Green,
was interested in the challenge of the "Grow a Jeep Project."
He graciously offered his welder, a powerful commercial grade ESAB
Migmaster 251 MIG welder to me for the frame and roll cage welding
portions of the project. He was also kind enough to spend one of
his days off working on the "Rock Taxi" with me. Another
friend and club member, Phil Davis, took a vacation day to assist,
as well. He is either crazy or a true friend to spend his vacation
working on someone else's Jeep. Thanks to Mike and Phil! I couldn't
have done it without your help.
After
building box tubing that closely matched the inside dimension of
the OEM frame, the inserts were placed into the frame, the Jeep
was measured, leveled, aligned, and then welded together. After
welding the inserts into the frame, plating was added on the outside
of the original frame. No special tools or time was spent on carefully
assuring that all was "square," as hard off-roading and
a few rollovers had tweaked the frame all along it's length, anyway.
It is closer to true now than it was before we started, however.
Here is the
lengthened frame before reassembly and the body work began.
Filling in
the Gaps:
Now begins the most tedious portion of the growth project -
building the body. Since the aftermarket replacment panels I found
did not match the contours of the top lip of the tub, I picked up
some flat sheet metal to build the floor and to fill the rest of
the holes in the tub. After piecing the new sections in, some grinding
and smoothing was done and the tub was ready for paint. A quick
trip to Russ Baer, owner of BaerTrax, a local Jeep Fabrication specialist,
and the 2"x.120 wall DOM tubing was bent for building a new
roll cage. After cutting, notching and welding it together, I installed
it in the Jeep, paint was shot and the lengthening project was complete.
