The solder fittings were not soldered but glued using JustForCopper which is meant to create joins pressure rated to 500psi on copper and brass.

Its good stuff as it needs no heat or messing about with solder and flux, just rough up the socket and pipe, apply glue to both, slot together and a few seconds later its immovable. It fully cures over a couple of hours I think but it grips tight seconds after it stops moving.

First class work.

Care to expound a bit on the "severely customized" blowgun?

Well maybe thats a little bit of an exaggeration, defnitely very cut up.

All the nozzle was cut back to leave about 5mm after the actual valve mechanism and the lever was cut back to what you can see there and ground and polished off.

The nozzle had to be cut back to allow the grip to be formed which is swept backwards and the lever was trimmed back to form a trigger that could be operated with one finger and so give it a neater appearance. The lever would also be pointing way off the slope of the grip if it had been left alone.

Ps. Was anyone else getting an annoying red box instead of pictures? I've just changed the links from some http://redproxy gibberish to the original imageshack links.

Hope you can see them now. I'd used the proxy site AFTER posting this thread, I don't know how it messed it up.

Anyway, the next stage on its design is using more polymorph (the stuff the grip was made of) to mould a foregrip.

I Googled polymorph but couldn't find much. Is it polycaprolactone, or is polymorph some type of brand name in the U.K.?

I think it's similar to <a href="http://shapelock.com/">ShapeLock</a>

Really cool stuff... I'm going to have to get some and try it out.

Looks the same. Should be white granules that you soften in hot water and mould by hand then it hardens again as it cools.

I spent an hour, 200g of polymorph and 7 kettles of boiling water to get that grip moulded around the pipe core. Was completely worth it though.

How does the stuff feel? Slick? Or is it easy to handle?

Does it dent or scratch easily?
