962 recreation with a GT3 Heart...
Discussion
I have a question about all that brake force going into a couple of screw threads rather than directly to the bulkhead, Beautifully and ingenously made as it is is there no compromise there as opposed to bolting the m/c directly to the bulkhead? Or is it just the same as having an adjustable seat taking the strain albeit in the opposite direction.
Fantastic thread by the way, just curious.

Yes it's possible to overcome the acme stile thread if you push hard enough, but then you have to take into account the screws are also worm gear driven from the motor. Now the force needed has been increased by a factor of 10 again. Think of a block and tackle no brake but can hold 2 tons no problem . I did wonder if any of these electric seats frames actually had a catch lock on them like a normal manual frame, but it seemed none of them did, I checked my GMC Truck it has no catch, and the seat belt is attached to the seat at both ends so must be able to take say a bad accident G load with out moving.
The F1 guys talk about putting 100-150 kgs of force into the brake pedal, so lets say that's 75kgs per screw in compression that's an easy load to take to be honest. But yes I did think about it before I started and did a little research, valid question though bud Keep um coming, I'll take good ideas from anywhere, I'm not proud if it builds a better car.

Awesome build.
I have so many ideas of things I'd like to build, it's just the time, space, money and most lacking of all, ability that's holding me back.
So in the mean time I'll stick with pissing around with mountain bikes and use threads like this to keep me happy.
Not much between you and the dream then, just Money.....(apparently it buys anything)I have so many ideas of things I'd like to build, it's just the time, space, money and most lacking of all, ability that's holding me back.

and got some drive shafts made for the pedal box, so here it is moving under 12V power ....

Crap few days, Imprezza blow a rad last week ordered another on Ebay not here yet, but I have the good old faithful truck.... Or so I thought, fuel pump went in town today, so $200 to tow it back then GM wanted $400 for a pump unit (Also includes the sender and filter), but the same unit is $100 on Ebay delivered to my door in a weeks time.....
So now using the wife's car for work this week, luckily shes off work.
Broke my roughing cutter for the CNC Friday 6PM, after all the shops where shut, not forgetting Thursday I spent most of it in bed sick ... I'm going to crawl into a hole now and forget these 4 days off.....
The front I know whats happening as far as the suspension design is going, but the rear needed some more thought. Was going to use that old Porsche gearbox casing to space the engine forward away from the new gearbox, but I didn't really like the way it looked or the load paths the suspension/chassis would put into it.
So I've had a few hours head scratching and I think I've come up with a much better solution. Making my own bellhousing and spacer unit, allows me to put the engine and gearbox in exactly the position I want them, with the least compromise so that's whats happening.
The big rectangular box is the engine, crude yes but its all I need to do the Cad work.
The Triangular plate that connects the chassis to the gearbox was always going to be there but the new parts are between the engine and that plate. Yes basic but I'm just developing the idea for now.

Looking at the diagrams, what's the torsional rigidity like through the side mounted A frames?So I've had a few hours head scratching and I think I've come up with a much better solution.

Is it going to need more bracing to cope with the torque?
There will be 3 tubes per side the last one mounts higher into the cage and is more of a diagonal, and I intend to brace that one with a few X frames. The originals didn't brace it but If i can I will, as it all helps. The engine will take a vertical plain load thought the block, but hopfully not to much twisting load..
