Re: Snapey's 1935 Racing Biposto

Not much time to spend in the shed this weekend as the house and yard were well overdue for some maintenance. Luckily you can't trim trees easily after dark so I did get some work done on the Biposto. I also made some important decisions that will affect the driving position and hence the whole look of the car.
The big job this weekend was to chop about 15-16 inches off the front of both chassis rails. I will recycle the rear forged steel spring hanging points by now using them on the front. I have also removed the main front cross member. My intention is to reuse the original front cross tube that went across just behind the front end of the chassis in a similar location and then replace the main front cross member with a new fabricated unit that will also incorporate the front engine mount. This should cut down on weight and also give me more room to locate the blower and manifolding etc.
One night early last week I was in the shed looking at the car and trying to figure out how I might get the pedals and brake cross shaft to function as they should and how this might affect the seating position. I wanted the seating position to be not far in front of the rear wheels. Sitting in the driver's seat I want to be able to touch the rear wheel. This was looking like a real problem, until I thought to move the brake cross shaft. If I move this rearward about 18" (which puts it just behind the centre of the crucifix) I can then move the pedal assembly about the same amount which will put the seats much closer to where I want them. I should be able to do this and I only have to drill 6 new holes. The pedal assembly and its mounting will have to be reworked somewhat but that shouldn't be too bad - especially since the intension is to change the car to right hand drive anyway.
This also has the advantage of allowing me to move the engine back and down a little more, although I will have to be careful that the prop shaft won't interfere with the new location of the brake cross shaft.
I am really happy with the way the project is coming together so far. A number of my 'ideas' about the look and design of the car are actually falling into place much easier than I had expected. At the moment solutions seem to be unexpededly solving other problems at the same time. This will soon change though, when I start wooking on some of the more detailed aspects of the car. I am not exactly avoiding these at the moment, but I would love to keep the current success rate rolling along for a little while longer before I go opening up any cans with 'Worms' written on the side...
Anyway, that's about it for now. We should be home next weekend, so will get to spend a little more time on it then.
