Tool to price up projects

[Tristan.]

Anyone who's ever undertaken a project bike knows the cost generally doubles at least over the initial estimate. Recently I've been deciding what to do with the 5 bikes in bits in my garage and I decided to make a quick document to track what parts are needed, how much they'll cost etc so I can make a cost vs output decision.

I've done similar for every project but generally just on the back of a fag packet, this is a little more geeky but I think it has potential. I started filling it in for my NSR but then got bored. I'll stick it up here in case it helps anyone else, I'd like to eventually have filled it in for enough bikes that I can get some meaningful average cost values, so when considering a project I can quickly look over it, work out what I'll need to buy and have a quick rough idea of the cost.
