Still ill but had a moderately productive day, got the seat platform finished and in place, when I did a mock-up with the seat included I found my seat height was about 2.5cm too low, It might not sound a lot but it has an effect on pedal reach and leg angle so I added a 2.5cm square of timber to the top of each of the four seat platform risers, it has uglyfied some of the clean lines but it's solid and the right height now and the uglyness will be hidden by MDF panels at the end anyway. Still to do with the seat are to install the cross spars underneath to bolster the already solid seating.
Things I learned today, firstly I
hate knots, I didn't realise they could be such trouble, with the CLS timber I'm using the knots are so solid that I actually broke a 4mm drill bit on one, forget driling through them, forget chiselling them, forget screwing through them, just avoid them even if it means a slightly less than optimal screw position.
The second thing I learned was that the adage of "measure twice, cut once" is not enough on a build like this, a more useful version of "measure twice, test, evaluate, measure again then cut" seems to be the order of the day.
I also started the first of the steering spars, I'm double bracing these, and quite like the look it gives, the two angle struts are of different size to optimize the getting in / out space, but should still offer more support than a single angle strut:
I borrowed my brothers adjustable wheel stand to find the ideal steering spar position, this helped a lot.
Tomorrow I'll complete this one and start on assembling the second, the pieces for it are already cut.
After that it's just the steering platform that will span the spars, and the pedal deck to go, paint and carpet and then I'll start thinking about the TV / Monitor stand.
Total cost so far is about £50, I can see the materials to finish up being about another £15 to £20 max so other than my time this has been a pretty cheap build.
