To avoid too many multiple posts, I\'m gonna answer a couple here:

I\'ve tried it, and all the paint gets rubbed off, or the glue gets everywhere, or a gap shows up....
Seriously, how do you people do it?
This definitely can be a problem, so I usually give it a coat of varnish before assembling, just so I don\'t rub paint off. If you use spray varnish, then it\'s important to remember to go back and scrape/sand the area that will be glued, as varnish will prevent a good bond.

This was my concern regarding painting it first. What do I do about the gaps? Can I use GS as putty like Valander suggested? Then once the GS hardens remove the pinned piece? I never used GS before so I have no idea of what it is capable of.
I don\'t think using GS would work well for that, as it tends to bond pretty well to metal, so it would be difficult to pull it out. That\'s the reason I went with Sculpey--yeah, I had to bake it afterwords, but it didn\'t bond immediately. I suppose that if you coat the pin and so on with some light oil and then stick it in the GS, it might come apart after the putty\'s cured... Something to try on my next \'jack.
Also about GS, can you smooth it out using water? I usually use milliput and once I fill a gap I smooth it out with water and it makes for a very nice looking joint (not the kind you smoke).
You can kind of smooth it out with water, but I\'ve found that using vegetable oil or the like works better. Mainly, though, that\'s just to keep it from sticking to the tools, not for thinning the putty (I know you can kind of do that with milliput, can\'t you?).
