The rebuild of Talbot Darracq 700
DIR By: RhysN

---------------------------------------------------------
Some background. This is the CycleKart that Wes Raynor had
built, and was the header on the Facebook page, CyclekartsGb for
some time, in which Wes tried to raise interest. Wes was the
guiding force behind Mardave slot, and radio controlled cars for
many years, his efforts to develop Magracer had seemingly gone
unnoticed, so the CycleKart bug nibbled him some, sadly nobody
else much in this country was making any real effort to
participate, until Graham Hill and I, along with Sarah (Graham's
sister in law) went to see him. He proudly showed us the CK,
then drove down the drive, turned around on his front garden and
came back up the drive. Graham was hooked, however, it was all
too late for Wes, apparently, and he had it up for sale. As it's
such a lovely shape, I could not resist. Eventually it arrived
on the back of Graham's CK transporter here in Tamworth, and a
thorough study was made.
I decided there were so many things I wanted to change, that a
full rebuild was the best solution. No offence to Wes, he was
proving ideas, but many things might not have stood a day of
use.
The structure is largely the plywood box, with strip planked
tail and bonnet. Wes had done a nice job of these, but I wanted
it stronger. First task was to remove all the mechanicals, and
then study what I had. Being comfortable with a plywood
monocoque, I then removed all the paint from the outside, a
little sanding, and then it received a full outer layer of
fibreglass twill cloth with West System epoxy.
With the shell now locked into place, it has stiffened
immensely, I attacked the inside. Rolling it over I unscrewed
the floor panels, and made a lot of sawdust as I used the
grinder with a flap disc to cut out some small bits of "stuff"
which had held the strip planking together, and other random
pieces. The inside of the front cowling received the most
shaping, it's now down to a bit more of a pleasing contour on
the inside to match (roughly) the great shape originally done.
Some of the mutli piecebulkhaeds have been replaced with new
ones cut from 12 mm ply, rather than pieces of softwood screwed
together.
Back the right way up, and I have started to glue floor panels
in, and glass them in along the floor to side joints with
biaxial glass tape, epoxy again. Current status is waiting for
the next lot of West to arrive from East Coast Fibreglass,
although all the glass is now cut. Once it's all a unit,
hopefully with a much enhanced level of structural integrity
(nice phrase that), I will be filling and fairing the weave of
the outside skin ready for paint!

It’s a lovely shape Rhys, begging to be finished and put on the
track. Your doing a brilliant job on her

You can only see from a distance Steve!
I decided that the tube rear axle, which only just went into the
wheels may not be man enough, so splashed out and bought a solid
one. As Wes had used all 30 mm parts, that's what it is, a new
alloy V belt pulley replaced the cast iron one, single groove
this time, I suspect the extra weight of the axle is compensated
for by the light alloy pulley.
I'm having some collars machined up for the axle ends so there
will be support for the outer end. They fit where the bearing
was, and a sliding fit on the axle. Retaining the whol shebang
will be the functional "Knock ons" which Mike Thorpe in NZ cast.
For simplicity the axle end will have a thread in the middle and
some form of bolt will pass through the knock ons.
I have made up new chain and belt guards for inside the cockpit,
they are on their way to being installed, trusty rivnuts will be
used so that I can remove them reliably. I do have some Dzus
fasteners here, but haven't yet learned how to install them.
The front axle I'm going to re-use, at least till I know if it's
not strong enough! I am adding some braces in though. See the
"before and after" (obviously before being taken for welding)
Stub axles will remain for the moment. Somebody has to see if
smaller diameter stub axles can be used. The plan is to make
another axle which can use alternate ones, which could be
readily swapped if/when the original gives up. The idea is that
it would be in the spares department of the new (to me)
CycleKart hauler for on site playing.

Believe it or not, I have been doing something on the car most
days. Now all the internal glassing is done, and the filling and
fairing of the weave on the outside of the shell has begun.
First plastering of fairing filler applied. Maybe some sanding
tomorrow? The idea of doing this as well as I can is two fold.If
I decide to take a mould off it's as near a finished surface as
can be, and secondly I want it to look good.
The new back axle is all in place, parking brake re-installed
with a new caliper bracket (again). This one allows for caliper
float.
I have made new engine bay sides. Wes had made good ones, but
again, as I had some spare slightly more gutsy ply I cut new
ones, and routed out the aperture to fit the mesh in. They are
now one piece rather than an assembly of thin ply and pieces of
softwood. Yes they are heavier, but as they are one piece they
want fall apart.
The dummy exhaust (again one of Wes' pieces of art) now has a
piece of Airex type foam wit a bit of cloth on each side. Again
so I don't have to fix it too soon.
I will be making up another set of the Hartford friction shocks
for the front of this, I think they may be needed to control the
soft springs. If anybody else want's I have the arms cut (water
jet/laser) and the labels I have plenty. Yes, i have used these
before, and yes they do work.

Stopped! Sitting on top of the Saab to make room in the shed.

I am so glad that someone got Wes's kart that is bringing it
back to it's glory. I was chatting to him on our kart forum
about how nice I thought it was.
