Nostromo Airlock part 2

I've printed the pads that surround the airlock doors from polystyrene filament. Here they've been sanded and filled and lightly sprayed with some grey primer.


Something that's been troubling me is how I would bend up the tubular racks seen on both walls. I made a couple of jigs and I think the technique has promise.

The aluminum block in the center is fixed in place by a couple of screws through the bottom of the plate. The 1/8" rod is held against the block with one of the clamps, then heated locally with a heat gun and bent. The next clamp hold it in place and you repeat for the next one, working around the block..The two ends overlap each other. The two overlapping ends are cut flush with a razor blade and glued together. The groove in the top of the center block is to align the two ends while gluing.




A second fixture was made to get the 45 degree bends. This was made from MDF.
Again, a heat gun was used for bending.
