Just to close off this thread, I thought I'd bring it up to date.
Gareth finished the chair and rode it to Austria and back and then to the Dragon Rally. He'd enjoyed the whole project and the outfit had performed well, managing 65-70mph@50mpg. When he got back he thought about it and the money he'd shelled out and he made the decision to sell the outfit complete on Ebay.
The buyer ended up paying £1,100 for the complete rig and he arrived with his wife and then rode it back to Nottingham with no problems.
So, after nearly 3,000 miles, he recovered most of the money he'd spent on the project. For him the enjoyment had been the whole adventure of building the chair and riding it to Austria so he doesn't see the time spent in the workshop as wasted.
When we were at the Dragon a lot of people commented on how they had been viewing the project's progress via the blog which was really nice. In fact the bloke who bought the rig had also been visiting the blog before it came up for sale.
gareth will have another chair sometime, but for now he is concentrating on getting his '02 Bandit 1200 back on the road.
As for me, I will shortly be bolting my old Wasp chair back onto an XBR for use as a kid's taxi and bolting a proper tradesman's box onto a chassis fixed to my CB500.
