Nuke Chutes

Postby Lister » Wed Mar 02, 2016 11:23 pm

I have been building mini nuke kits for people in the states.. I needed a 40" chute for them and had the idea of making it look like a radiation symbol to go with the mini nuke rockets.. so I got my tailor to knock these up.. aka Mum, she has done a much better job than I could ever do.

The have 6 150lb braided kevlar lines and will each have deployment bags.. the are all custom colours to match the custom coloured FG mini nukes.

will add more pics of deployment bags and other chutes tomorrow.

Nuke Chutes - love it 8)

I got to inspect one of these the other day, they are pretty good!

Thanks. The had to go with "Nuke Chutes" to fit the rest of the theme :) Think the yellow and black are the go.. though may blend in a bit in dry grass.. good thing I enjoy long walks through the paddock :lol:

They look great Luke, the black will stand out enough in dry grass so I would not worry about that... :-)

I modified a soldering iron tip to be like a chisel point, then made a wooden template for the 12" nuke chute gores and went about cutting them out of ripstop with the soldering iron.. this is how they came out. You can see there are no frayed edges and it actually cuts really well once you get the hang of it. Very good way to cut ripstop :)

Nice.
Bunnings has a soldering iron that comes with a collet chuck to take X-Acto style knife blades, works great.
It also comes with a pile of tips for burning patterns into wood, I thought I'd test it for 'welding' chute seams rather than stitching them, but it was too hot.
Eventually I'll get around to trying a variable power supply in an attempt to control the heat.

I will have to check those out.. would welding two panels together make a strong enough join for a parachute? What about the vacuum bagging heat press type device, would that be a better option for welding two panels together?

I think so, possibly even stronger, but purely speculation, I haven't tested it yet.
My sole motive for trying welded seams is speed. I suck at stitching, very slow and the stitches are damned ugly.

A sealer might work, tho it wouldn't work with Hemi or Semi-elliptical chutes with those curved gores.

Just made a metal template for the 12 nuke chute gores.. it cuts much cleaner, will mean its alot easier to make them as they dont need to have the edges finished to stop them fraying :)

12" metal nuke chute template and almost finished chute with 150lb shroud lines and it will have a nomex deployment bag :)

The gadget you're talking about is a "wood burning" tool:
http://www.bunnings.com.au/tradeflame-wood-burning-kit_p5910279

I think cutting them with heat is a great idea. Be interesting to see if a laser cutter finished the edges like that (that's for when you're doing lots of a hundred, unless you plan to have minions)

I've also had good results with CA glue - I've stitched the gores and finished the seams with CA (you can tack down the stitching too). I've wondered if CA alone might be strong enough for a light-ish load - like I also wonder if a zig zag "spot weld" from your wood burner would do?

Have you thought of using a piece of nichrome wire connected to a power supply to make a hotwire cutter, like what is used for cutting styrofoam etc? Holding the wire taught would be a great way to get a dead-straight edge I think.

Im not sure how well a wire cutter would work.. if you dont pull the fabric away from the heat source during cutting then it can reweld.. and you need to keep pressure on the template, cut and pull away the excess to cut nylon well, from what I have seen most wire cutters require both hands?
you get a very clean cut with an aluminium template and soldering iron.
