Off to a flying start... first two rail laminations cut out,
ready for cleaning up. 6 more to go... Im going to clean one of
them up to the line by hand and use it as a router template for
the other 7. Also- a Spring. Ive been experimenting with various
methods of attaching an eye to the spring, i think i know what i
need to do now. Finish tidying the shed up so i can play with
the welder without burning the shed down....

looks brilliant. really interesting design and you seem to be
putting it into practice well!

Cheers! Im certainly having lots of fun trying to work out the
best way to do things. I built a mirror dinghy as a teenager, it
has prompted a whole load of memories to come flooding back, of
wiring joints, glassing seams and etc etc... i reckon once ive
cut the rail laminations out ill cut out the bottom skins and
the seat parts, and then play with all the main parts for a
while before notching and wiring and gluing them all up. Im
thinking of building the basic chassis/tub structure and then
varnishing the insides of the box structures with marine
varnish, putting the last skins on and then painting the whole
external chassis structure with truck bed paint. Any holes
through the frame (engine/suspension mounts etc) will be drilled
slightly oversized and then have stainless sheaves epoxied in
for the bolts to pass through. Once ive got that all done then
itll be time to start the bodywork, although some things are in
motion- i bought a riley elf radiator surround off ebay for 25£,
to modify into something suitable. Hopefully it wont require too
much persuasion from the angle grinder or bodging hammer..

I like this idea of making a wooden chassis. I see you can form
so really nice shapes.

It’s marvellous stuff really- light and strong, easy to
bend, and with careful design it should be extremely stiff as
well. I got 4 more laminations cut out today on the big bench at
work. So thats six so far, to be laminated up straight for the
inner face and cores of the two rails. Im planning on cutting
the last pair so they can be bent out to follow the Riley
chassis shape, and screwed and glued to internal bulkheads and
then skinned over so that each half of the straight chassis
rails will incorporate an outer, shaped box section structure.
Nice and strong! Then join the two together with the other box
sections that form the seat/floor/rear bulkhead/front structure.
You can pick all the chassis rails up with one hand quite
easily, theyre not very heavy at all. They are one sheet of 8x4
with a small pile of useful offcuts. The seat and bulkheads will
be made from the other sheet of 8x4, so i expect they will weigh
about the same, so not very much. im betting that the finished
wooden chassis structure itself will weigh a fair proportion
less than a metal chassis weighs.. itll pile on some pounds
with the suspension supports and engine mount, but im guessing
shell come in quite trim when all done.
Im presuming this is a good idea.... i know a reasonable amount
about boats and guitars but bugger all about cars. ;c)

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.
