Had a good few hours on the car today, I fabricated the other chassis mounting box, tacked them both to the chassis and lined up the axle, before centering it and marking where the bolt holes were to be drilled.
I then ground off the tack welds, took the boxes to my drill press and drilled the mounting holes up to 10mm, they need to be opened further to 14.5mm but I don't have a drill bit in the garage to suit at the moment. I think I have some in my toolbox in work so I'll have a look tomorrow afternoon and then drill the holes out on Tuesday.
Yesterday I made a run to Bristol to collect a set of front hub assemblies from a Sylvia Striker (actually from a Ford Sierra) as they fit standard locost wishbones. I've given up on the idea of using the BMW front hubs as to be honest I'm not 100% confident in my ability to fabricate the front wishbones accurately enough to maintain proper wheel alignment. Even a slight mis-alignment would make the car's handling awful.
The other major decision I've made this week is that I'm not going to submit the car for an IVA test, which means it cant be driven on the road. This isn't a big deal for me, when I finished my last car project (restoring a Ford Capri) I hardly used it, and it sat in the garage for months at a time wasting tax, insurance and mot money. This car will be so mad when it's finished then a racetrack is the only real place for it. So when it's done I'll take it on track days, this also gives me another project for afterwards - build a car trailer to carry it on! All this means, I can leave it sitting in the garage - not costing me a thing. Also, the build is graetly simplified as things like catalytic convertors, lights, chassis number and all the attached beauracracy are not required.
