Title: 08 Pro-X
Post by: George Herrin on February 25, 2008, 12:47:59 am
here is what roughly 4 and a half hours resulted in. I am so behind on some of my stuff that after the clinic Larry and Jeannie came over spent the night and help me out. This is a combo of Jeannie's pro-x and my Pro-x. Jeannie drives it locally and I will drive it Nationally. Gonna be a rocket. Its an MTD walkthru chassis Very Light and 4 inches off the ground. Burris k21 grooved tires all the way around. Simulated deck will serve for where the feet will actually go. Gonna pop rivet aluminum to the bottom of the frame work. Centrifugal clutch with pulley then a right angle box under the fender. This thing is LOW LOW LOW. Did I say low. I like it so much gonna make a sportsman chassis with another I have.

Dash/steering column support all tubing is thin wall 3/4 tubing

The next 7 pictures are simply different angles of the support tubing under the frame and how I did it.

Where we come to a change in angle we cut the tubing bent it and welded it back to tegther to get it to follow the contour of the chassis.

Is important you start with a straight chassis before you do all this work.

Ok lots a wrok done and few pictures were taken here is an overall view of the drive train it uses a centrifugal ratech mini cup  clutch and 1 to1 gear box

Clutch has a pulley welded on and the same size on gear box uses a belt tensioning setup basically a clutch system as I use on any other prepared build. Only this ons is not billet.

Still have to wire it add the trhottle cable, get a throttle lever for the steering wheel, bleed brakes and finsih the head. The exhaust is done and used a silver ceramic high temp paint o it. Already used this on another exhaust and it doesn't turn colors great stuff. Thats all for now
