Okay,
so apologies for not having explained the various switches being employed as
previously promised. I've decided that I need one more switch and its not
that interesting a topic anyway.
What is much more interesting is the fact that
there are some panels on the chassis. I'd left the chassis with Dave
at Track Developments last week and he'd made
plenty of progress getting most of the panels roughly cut to size and some of
them drilled and virtually ready to bond and rivet on. To this end we
concentrated on fitting the floor and
seat-back bulkhead. To make subsequent work a lot easier however, it
makes sense to get the internal panels cut and drilled where they attach to the
bottom chassis rails as its tough to get the drill in once the floor is on.
Once this was all done, I ran a wet'n'dry
contour sanding block around each of the panel edges and then degreased both
the chassis and the panel. The chassis then got a spray of wax oil in
each of the rivet holes. I appreciate that rust is unlikely to be the
factor that determines when the life of a race car chassis is up but it can't
do any harm and hopefully stops any swarf etc from rattling about.
I should mention that Dave had also put the
chassis onto a clever rotisserie/spit that means that the chassis can be
spun around without lots of muscle or damage to the powdercoat - it makes life
so (relatively) easy. At last it was time to squeeze some bonding
compound onto the chassis. I've used Car Builder's Solutions PU adhesive
for years - its economical and really does stick like polyurethane to a
blanket (don't ever wear tidy clothes when using this stuff). You can abrade the paint to get a better key apparently but I've never found it necessary; not when you have a rivet every 40mm.
Here's Dave having a go with the PU - despite warming it up, it's hard work for the tendons in your wrist as you slowly squeeze it out of the tube - it's therefore great to be able to pass it across to someone else while you have a rest.
Then, having enlisted the help of local MEV Exocet builder Simon, the three of us carefully lowered the floor into position, adding a few clecos and rivets as we did. Roughly an hour later and it was looking spot-on.We then repeated the process with the back panel, which admittedly was a little more awkward - we guess because the panel had shrunk by a tiny amount in the cold.
Finally, I simply slid the rear tunnel cover into place. This is going to be secured with rivnuts and bolts to allow me to check the bolts on the diff.
Am I happy? Too bloody right. It looks great and we're actually constructing a kit car at last. I don't know why I doubted the powdercoat colour now either. I think it looks very classy against the aluminium. I'll need to buy shares in Autosol to keep it that way, but we'll cross that bridge when we come to it.
In other news, the reverse 'slave' gear is back from HPC with teeth rounded and steel hardened - 6 weeks ahead of the quoted lead time. Also, my Digidash 2 Lite with IR lap timer is imminent - this as come at an excellent price with bags of useful advice from Andy at AB Performance.
After a pretty horrible week, yesterday was a good day.

Looking sweet...........
banging on with the panelling, its great to start putting things back onto the chassis !!!
keep it up
