Project bike, ... check. Space cleared out in the garage, ... check. Special tools you'll need to do the work, ... um, maybe we need a few more things, but they can be expensive, so being the ambitious and resourceful person you are, why not just make your own?
Quite a few guys have run into the same situation and a few of them have shared the plans for their homemade tool so you can build some yourself or at least, use what they did as a starting point for your own improved versions.
Homemadetools is a pretty cool site that offers tool users and builders a place to share their ideas. The tools are for almost every kind of work, but just looking in the motorcycle and automotive sections gives you quite a variety, but don't confine your browsing to just those, there's good stuff throughout. These are the kinds of things that used to be common in old issues of Mechanix Illustrated and Modern Mechanix and similar mags, it's just a new place to look.
Is everything well engineered and sure to work? Maybe not, but you can browse around, sift through and decide for yourself what might work for you. Lots of ideas for sure. Cool!
