Has there been any further development on this project? I'm in a similar situation with I bike that I'd love to bring back to life, but don't want to spend a lot to do so (tube replacement is not really an option) and I'd rather not repaint. I'll be measuring the tubes and see if I want to invest in the blocks.

I read somewhere on BF before (but of course can't find it now) that someone made their own wooden blocks and assume that would cause less paint damage if used.
