Thank you for your inspiration MIA.
Good news is that the body is still available at Pendle. You can still get one if you wish.

First step to making an aluminum chassis is to cut the material.
I use the end of the part to measure from so it’s best if all the ends are square to each other. I touch the end of the tubing to the sanding disc 4-times, rotating the tubing a quarter turn each time. It’s usually square after 4-rotations. Make sure your sanding disc is 90-degrees true before you start.
A permanent marker is used to mark the general area where the cross-hairs are going to end up. It easily comes off with lacquer thinner when the work is done. You can see at a glance that the drawing lines up with the marks on the aluminum.
To locate the center-line for the body posts and guide. I switch the calipers to inches. It’s been reading metric up until now. Measure the overall width of the tubing. Easy to divide 0.752″.
Then scribe a line with the calipers using another larger peice of aluminum along side the work to have less wandering. Flip the chassis the other way and scribe it again. There will always be a slight deviation. The space between the lines is the exact center. I can easily drill between the lines with a pilot drill.
I also use the larger aluminum tubing at the ends of the chassis for scribing lines with the calipers. Makes for very accurate cross-hairs.
Once the cross-hairs are scribed. To the drill press it goes. Please refer to the following workshop for drilling and reaming for bearings.
Monday, October 29, 2018 (7:00-9:30pm) Basic Aluminum Chassis Design/Build
The tubing visits the bandsaw to cut away the top excess material. Then the sharp edges are sanded smooth. Final wash. Then install the parts. Body posts are install on the chassis waiting to be epoxied into the body.
Looks about 3mm too high yet.
After removing and test fitting the posts a few times to shave a little more material. We finally have contact with the fenders. Then epoxy the posts. Final step is to install the body washers. We have body-float.
It runs. It needs a driver, interior, windows, paint, head/tail lights, and livery. Hopefully before Monday.
