Single seater
#25
Hi Rekkers

Hopefully these pictures show the offset - how we set it all up was very simple, I measure the diff, then shifted it to the left till the torque tube mount was alongside the left chassis rail, then measured it all again & the difference was 200mm. The diff was then cut & welded to suit.

Then it was a case of positioning a dummy crank case & gearbox casing on dummy feet & using a bit of pipe out the back of the gearbox to simulate the prop shaft everything was adjusted till with me sitting on a box on the floor in between the chassis rails, I could fit into the 'body line' and still be able to operate the clutch & the brake. 

The pedals were worked & re-worked & re-worked again until the clutch arm mirrored the bellhousing shape for maximum 'tuck' alongside the bellhousing. The attached picture was taken during the firewall mock up & before I lengthened the brake arm & rotated the foot pad 180*. The little aluminium angle at the base of the clutch is my heel stop. I had to make a ridge in the floor to accommodate the brake pull rod - I insisted on mechanical brakes as I have enough other hydraulic systems to maintain. Of course I didn't anneal the panel & it split necessitating the little repair patch. The brake cross shaft was also re-located to allow for the new pedal positions. I'm using a needle roller Lavine steering box, hence the brake pedal is on a purpose made shaft bolted into the RHS chassis rail & it has a wedge to ensure that it's parallel with the line of 'push'

The throttle I put into a bulge in the side panel. That throttle pedal is all that remains from my late uncle's "Consul Special" which was written off after hitting a bank in the early '60's. The chassis / body extensions were cut & shut to provide a mounting for the sides of the body frame

I think our advantages were that we had a blank canvas, some fairly wild imagination, an extremely talented engineering friend & that we tried hard to keep true to an evocation of the Kaye Petre works car profile + stick to the period mods as per the 750 bulletins. Obviously we don't have VSCC rules out here, but I suspect that we are mostly safely within them anyway.

The MAG blower is such a pretty little aluminium casting & to this end was ultimately stuck out front & driven off the nose of the crank via a Yamaha 650cc shaft drive incorporating a universal joint & such is are the talents of Steven Murphy of SBM Engineering that there is no vibration up to our imposed limit of 6000 rpm. It sucks through a 1.5" SU which is tucked inside a little scoop I fabricated to ram feed air into the trumpet. It seems to all work, thus far we haven't ingested any errant squirrels, low flying pigeons or small children....  Rolleyes

Yes the blower screams very nicely  Big Grin
