Forgot pic.
Therell be more layers of either bendy modelling ply or veneer.
Ive got loads of rosewood veneer that might be fun to do the
insides with. On the other hand, im also debating about covering
the vertical inner faces of the cockpit/seat back with some
‘tweed guitar amp covering cloth’, which i have
loads of. Like a late fifties Fender champ, or guitar case. Its
yellowish when new, but can be aged with dilute stains or washes
of shellac, and then sealed to waterproof with varnish or
lacquer. As long as the substrate is waterproof with either
glass fibre or varnish itll be fine, and look Ace, and very
vintage.

Picture of two tweed guitar amps to illustrate- un tinted but
sealed on top, tinted and then aged with dilute shellac and
sealed on the bottom

I like the tweed and think it will make a very period looking
interior. Its very similar to the inside of my old Mercedes 500
sec but posher and would go well with a pair of plus fours.
Speedy progress indeed mr Synthpunk.

This is proceeding at some speed, and looking real nice!

Its proceeding with speed because wood is easy to make things
out of as long as you plan the route properly, and also because
Screws, and electric screwdriver, which makes things very fast..
Its all going to come completely apart again at least once as i
jiggle the design and add the rest of the boxing and skins, and
then get finally glued and screwed and then waterproofed
internally.
Its technically an English sports car, so that means it *will*
go rotten in the sills. Im trying to delay that as long as
possible... ;c)
I had been debating about drilling some holes in the hollow
parts and injecting them with expanding foam. Definitely wont
sink then...

Got a bit more trimming to size done today, using the router. I
now have both chassis rails and the tub sides trimmed to size,
and seemingly identical to each other, which is nice. Theres
going to be a bit more trimming done to notch different bits
into one another, and to put a couple of rebates in top and
bottom of the rails to put some skins onto the boxed sections on
the outside. Now that its all to size, its fairly easy to get a
feel for the stiffness of 4 layers of 6mm ply. Its very very
stiff. Itll be 6 layers/36mm thick at the ends of the suspension
horns by the time the inner tub and outer boxed sections are
attached. Plenty strong.
Ive been thinking about how to get my carbon fibre springs
mounted to the rails. Ive got some 50 mm long/13mm OD 304
stainless threaded sleeves in M8 and M10 flavours, that ill weld
or braze into the end of some suitably sized steel tube and
mount them through the rails with metal plates either side.
I need to make some eyes and mount them on the springs as well.
Ill document that process over in the tech forum under the ‘jump
stilt springs’ topic.
Im not sure how much ill get done tomorrow, ive trapped a nerve
in my neck this morning, so i might end up spendin the rest of
the weekend lying flat on the floor complaining alot.

Thank you Science for the invention of painkillers.
And also thank you Hitachi for inventing the M12 series of
routers. pretty much the Toyota Hiace of woodworking machines.
Noisy and indestructible.
Ive started notching, rebating and generally going a bit
woodworky on the starboard side boxing.
Hers a pic.

Threw the bits in the car and took them to work this afternoon
to weigh them. The left and right sides should weigh the same,
the slightly more complete right hand side (tub side, rail,
mostly complete torsion box structure) weighs 5.7 kilos. The
seat weighs 5.7 as well. On the assumption that they’ll gain a
little bit of weight as they get finished off, let’s call it 6
kilos each. So we’re at 18kg all in currently. Maybe another
couple kilos on top for cockpit floor and front torsion box, and
well be at around twenty kilos or so for the complete lower
chassis structure.

That is an impressive weight so far! you should have a light
(and therefore fast out of the corners) cyclekart! im really
enjoying seeing how you are doing this as its very different

One thing i havent fully worked out yet is whether or not to
build the whole car as one structure (which would certainly be
both the strongest and lightest option), or build the
chassis/tub and external coachwork as two or more separate units
that are detachable from each other for ease of maintenance and
modifications.
Up until recently i was a roadie, which is one of the reasons
that this little car is probably going to incorporate a lot of
random bits of repurposed music gear ive accumulated over the
years; thats mostly whats in my spare junk box..* If i make the
bodywork detachable, i was planning on locking it in place using
the heavy duty recessed Penn-Elcom recessed, lockable flight
case latches that are fitted to pretty much every proper
flightcase ever. I also thought that a couple of similarly
recessed sprung Penn flightcase handles mounted in the outside
of the boxed in sections of the chassis (that im currently
making the first of,) placed at the cars Centre of Gravity,
which i figure would be useful both for lifting/pushing it onto
a trailer and then securing it to said trailer with load straps.
* for instance i think it will be fun to make a cycle kart
incorporating a bit of aluminium for the dash that at one point
in its life was part of one of Kraftwerk’s synthesizers... the
bonnet straps will be held in place with some brackets from some
leather handles salvaged from a broken flightcase that belonged
to Pink Floyd. And so on and so forth. The company i work for
nowadays is based in Scottsdale Arizona, where i beleive they
have a cyclekart GP through the streets in normal years. I could
probably get official approval for affixing one of our lovely
chrome amplifier logos to the front grille to go with the Riley
one.. almost certainly if i go for my plan of also doing the
interior in luggage tweed..
