Thanks for the compliment, Doug. The bike is in the pic due to the fact, like most others, I am building my boat in a two car garage. I love that bike, but wheeling the 750lb monster in and out of the garage can be a bit of a pain. It's all worth it in the end, though. The wife also parks her jeep in there. But, it's a little easier to move in and out.
As far as cost, I haven't finished yet, but I think it will cost somewhere in the neighborhood, of $300 for the first one. By that I mean if you don't already have some of the supplies laying around and this is not counting any tools you might find useful in the process. You can save considerably if you already have some epoxy and some of the wood, but don't try to cut corners to much.
Let me know when you start to build. I will be glad to share some of the mistakes I have made and some of the guidance that Graham has given me in the classroom. I don't read the forum on a regular basis sometimes, so feel free to email me.
