While I had my brazing gear out this afternoon I converted the trike's seatpost into a 'lucky 7' type which has improved the seating position no end. The handlebars were also cut off short and re-positioned into a tiller-like position, but I still need to do further adjustments on this before it's properly workable. The next task will be to mount that blue Raleigh 20 bottom bracket post on the frame to put the pedals in a feet forward position. I took apart the exercise machine I was going to strip for handy tubing and the part that's sitting on the front wheel in the picture will become the front part of the bodyshell framework after it's been pruned a bit. It even has a bracket on it that I can use to mount the headlamp. Dense polyethylene foam has been used to make velomobile bodyshell cladding and I was thinking about using it, but I most probably won't as it's too suspiciously hi-tech a material for old fashioned me. I purchased a cheap camping mat made from the stuff with a thin alumminiumm foil backing for research purposes which I'll have a mess about with and report my findings so I'm not totally close minded about the possibility of using it. By the way posh Yoga places sell this stuff as yoga mats at a truly horrible price when it can be purchased at the Chinese discount shops for 1/10th the price so don't get stung if you're interested in making use of it.
