Just an update.
Well i played around with the strut and got it working right...with the panel off anyway

With the panel bolted on, the top strut fitting just touches the inside of the panel and pushes it out a bit when the door is fully up. I grinded it down a bit and got it to not push out the panel but it still scrapes a bit.
I want it to have at least half a centimeter of clearance but that can only be done by moving the strut positioning. But there is no room to move it any further over because it will be in the wheel arch.
So anyway... i'm going to get a new strut made and change the mounting points on both the arm and the bracket, then tune the strut again to feel even through the whole lifting motion.
Another problem i have is that it is a bit wobbly when up. I've never actually felt another car with scissor doors but everyone says they wobble a fair bit and from searching on the net i've found its a common problem and a lot of the companies selling them say its impossible to get rid of all the wobble and even real Lamborghini doors wobble supposedly. This is understandable because even the tiniest little movement at the pivot point of the hinge will mean a lot bigger movement at the end of the door.
But i want to have the most stable doors i can make so i'm changing most of the hinge to minimise wobbling. I'm making the whole arm thicker, adding a piece in at the top to lock it in place when fully raised, increasing the thickness of the part around the pivoting parts, adding a plate on the back of the bracket to stop it bending, adapting it to use bolts that can be used to tighten up the pivoting parts and getting expensive double row angular contact bearings that are designed to handle the axial and radial loads that the arm puts it under. I'm sure that after all of those changes that the only part to flex will be the door itself and the panel the hinge is bolted to and that will only be if you really pull on it.
I'm working all this week at the laser cutting place where i'm getting the parts cut, but i need to get the computer guys in the office to convert my designs into the format that the laser machines read before i can cut them. Tomorrow i'll be showing them the changes i need and hopefully i can get the parts cut this week. I ordered the bearings last tuesday so i should have them this week. Which only leaves the strut but i cant go to the place until saturday because i work 12hr days. Anyway i should have them finished soon as long as no more problems come up.
Do you guys mind having the wires running along the bottom edge of the arm?
