Does anyone remember the magazine Auto Modeller back in the late '70s early '80s? Ian Jenson was a sometime contributor and on one occasion presented a "how to" for an inexpensive club formula 1 chassis. I'm not too sure how to best describe it but it was a sort of flexi-board with rattley side rails arrangement and it used a basic economy Mabuchi 13UO motor for power.
Well, this chassis has been on my "to do" list since 1979 and I appreciate I'm a bit late handing in my homework Mr howmet, Sir but whatever. Here is progress report no.1:
To the garage...
Now I didn't use any particularly special tools for this project, just this SIMPLE CNC LASER CUTTER pictured here:
(btw, if anyone has a CNC LASER that I could try cutting with it please don't hesitate to drop me a line), a hammer, mole grips(*see below), a vice, various files and things, a junior hacksaw and a butane soldering iron. Probably forgotten something but that's more or less it.
Anyway on with the construction:
Step 1. The main parts were cut from brass and piano wire:
Step 2. The main frame is soldered together - I used the graph paper to ensure everything was lined up properly:
Step 3: The side rails are added. In fact I changed the design a little here, On the original, the front stay was 18swg piano wire soldered across the chassis front and feeding into short tubes soldered to the side rails. These were capped with even smaller bits of brass tube - almost too small for me to see let alone cut and hold! So, I simplified the arrangement by duplicating the rear stay but across the front of the chassis. Much easier to build, although I will need to modify the original guide arrangement too so it can pass over the new higher added tube.
Still to do, front axle/wheels, guide, body mounts and motor - I've a spare Fox lying about so I might try that rather than the 13UO. I'll probably get a new Betta shell for it but in the meantime I might press this Wolf shell into service. As with David's cars above this shell dates from the '70s and was painted freehand.
More when I get the rest of the bits!
* Incidentally, despite the grips, no moles were harmed in the making of this chassis.
