Ive found this picture of the car after it was sold to Kay Petre in the late thirties that shows the shape of the Riley chassis from above.. lots of curves!

And i think this is either her or the original owner from the side...note the underslung back end, and the really high front end.. so yeah, its an interesting shape to build within the constraints of a cyclekart; ive taken one liberty which is to increase the wheelbase by 6 inches to 72, cos the long bonnet is such a feature of this car, it looks like a noddy car if the bonnet gets too short. Im also quite tall.

Really interesting to read because you’re clearly so comfortable working with wood.  Any chance you’d post a sketch of your chassis design?

Looks like you're going to end up with a very stiff lightweight body / chassis unit. I'm thinking along the same lines for my next build, just need to get myself motivated to finish the Morgan first.

The plan is evolving and refining on a daily basis but this is fairly up to date-
Box section rails, box section tub made of triangles, hopefully ill be able to get most it from 2 sheets of 8x4. Most of it still needs finessing.

Another pic, courtesy of the ever wonderful MSPaint.... orange bits are solid, yellow bits are hollow.

I got some time today at lunch to cut out the last two chassis rail laminates and to cut one of the two 8x2 boards down into smaller pieces for making the floor and seat parts of the tub. I have one 8x2 left which will get cut in half to do the sides (maybe tomorrow? I’ve got Friday and Monday off) which will leave a couple of square feet at most left over in offcuts. I may have to invest in another half sheet of plywood in order to get the rest of the tub done. Tomorrow I’ll have to also assemble some sort of jury rigged router table to trim all the rough cut bits I’ve produced so far to exact size and shape. I’ve a couple of old bass speaker cabinets at home that should work quite well for improvising the router table out of. Thinking about it, they may well be a suitable source of reasonably sized, free Baltic Birch ply..hmmmmmm....

Today was reasonably productive. I got one of the rail laminates trimmed and finished to size, which is going to be the master pattern for all the rest. I also trimmed a load of bits for the seat to nominal size, ready for further fettling, along with the floor.
I also got my Riley Elf radiator surround, which I made a grille for using a scrapped PA speaker. I also appear to have annoyed the cat.

I like the use of a speaker front as the grill!

If this car goes horribly wrong and gets scrapped ill save that bit and turn it into a guitar amp.. i made the amplifier section for one for Jeff Beck many years ago that had a Daimler hearse grille/surround over a 15” speaker, and two tone leather over the rest of the cabinet. It was a 3 way collaboration between a guitar maker(cabinet and concept), an amp maker (me) and a silversmith (radiator badge and rille badge were solid silver), it looked super cool.

Some pictures of Wood;
Some trimmed roughed out bits of seat, the rails, and some pine for pattern making for the seat

The prototype seat bottom support roughly held in place between the 2 of the rail laminates; theres 2 triangles of pine and some more plywood to box that bit up that you cant see, all currently just screwed together. Ill make some proper triangles out of real wood when i can confirm it all fits.
There will then be a load of glue and loads more screws attached.
Ive had an idea regards driver comfort, so the bit of the seat you can see here is basically just the support. The actual seat will be woven Shaker style using 25mm nylon webbing and suspended just above this bit from four 1” wooden rails, connected at the corners. We had a baby this year during lockdown 1.0 and i made mrs Synthpunk a shaker style rocking chair for feedin the minime and drying socks on. the tape woven seat is very strong, comfortable, and springy, which is wot gave me the idea..
