It will sound strange, I am actually looking forward to this build. I can't go for laser cut frames, but I have enough equipment here to be able to make them up accurately, which is the main thing, what's becoming very clear is that there are some things to be very careful of when assembling the tower, in terms of parallel, vertical, and possibly most insidious, twist, and the only way to avoid them is to make sure that there are good bracings between lower and upper that will prevent them. After that, it will be down to adjustments and good quality materials, and a lot of care assembling things.
Given the Pi is still very much a development machine, I will be proceding with care, but I'm reasonably confident that it will be possible to get some good accuracy with this design, maybe with a few tweaks that will reduce the wear points, but that will be the joy of engineering, and I've done enough over the years to be reasonably happy that it will work out OK with care.
Many thanks for the detailed comments, they have helped, and fortunately, I have a long standing background in programming, so that will help a lot, most of the experience was with commerical type software, but several years putting together a very complex flight simulator based on a 20 machine PC based network was a help in that respect, so dealing with parameter files is not too worrying, as long as the documentation is accurate, and the data is good.
A long time ago, someone said to me that the only difference between being at the cutting edge or on the bleeding edge is the amount of pressure you're under, and that's very true. Hopefully, I won't be under too much pressure on this project, so will be able to take my time and get it right, rather than having to rush things to meet a deadline.
I will update progress here as it happens.
