Build Day 28- Tunnel Top, Gear Knob and Cycle Wings.

Day 28- Tunnel Top, Gear Knob and Cycle Wings.


Tunnel Top


This goes in fairly easily, just push the front end in, raise the handbrake handle and feed the handle through the hole. This is much easier when the other end of the handbrake cable is not attached.

Slides on nicely.


The new R themed gear knob and gauges look pretty good. Also the key-less ignition style tunnel top seems much more practical than the standard one, especially when twinned with the Soft Bits Tunnel Bag made for this type of top.

Cycle Wings

At this point I had to go so my dad continued without me. The process was started by first preparing the surfaces for the adhesive, by using sandpaper to roughen (increasing the surface area) the underside of the carbon wings, then using acetone (originally bought as the solvent for the impact adhesive) to remove the paint from the wing stays.

Removing paint with 99.5% Acetone.

With the wheels on the alignment was found and the position was marked in relation to the chassis. Then the wheel was removed and the adhesive applied (Sikaflex 221). Initially a small amount was used just to make the bond, then more was used to stop the accumulation of grit, sure up the bond and slightly make it more aerodynamic.




Instead of earthing the repeater to the wing stay dad extended the black lead, wrapped both in heat shrink then passed them through the wing stay.

RH wing, kinda sucks that the wings are pre drilled and that the repeaters are required by IVA, otherwise we wouldn't have bothered.

LH wing, held in place to let it dry. The wings are a little low, meaning that the top edge of the tyre has to be angled in under the wing first, then the bolts located.

As well as the cycle wings Dad attached the brackets, for the coolant bottle, and for the oil breather bottle, using the Sikaflex, meaning that we don't have to drill through any of the chassis tubes, thus possibly introducing moisture inside the tube. For the breather bottle he drilled out one of the rivets already there then riveted one bracket hole and finished with the adhesive.



We had agreed on this method of fixing the cycle wings on as Dad had previously done this on his Superlight, plus the adhesives these days are much stronger than they were in the late 90's, we don't believe even Caterham screw them on any more either, and we also agreed that the method of screwing the wings on doesn't look good at all.

Us so far. (as of 6th December, not the end of Jan which it is now, just not had time to write this thing).
