I actually saw this a few weeks ago watching youtube videos virully after a search for rocket motors eventually lead me to this pretty cool channel (he got a subscribe from me lol).



Not sure it it might suit your application Lister, but I'm planning on making one for other crafty projects.

Trick with the nylon cloth is that it isn't exactly stiff - sewing it requires three limbs (you use two hands to arrange the cloth and manage the tension while your foot drives the machine)... if you're not concentrating it's very easy to bunch up the cloth.

I suspect the trick with using a hot wire cutter would be similar - to maintain tension on the cloth while cutting it - with the metal template you get that for free.
Lister's point about the hot edges re-bonding is well taken.

I have seen commercial bag sealing and plastic cutting machines that are similar in appearance to a paper guillotine but with a hot blade... I have no idea where you'd get one or how much (I expect they're pretty expensive unless you score one in a clearing auction or something).

Your spot on, its one one of the things you need 3 sets of hands for.. I have found if you weigh the template or clamp it down you can free up one hand that would normally hold the template and pull away the nylon so you can just keep the tension on the nylon as your cutting with the other hand. It takes a little practice but defiantly worth it.. if only I had a cnc lathe to cut out the metal templates :)

This is the Droid you are looking for http://brother.com.au/products/scanncut/cm110-detail and the 3rd hand that you need http://www.sewline.com.au/product/glue-pen/
Many years ago the great British explorer George Mallory, who was to die on Mount Everest, was asked why did he want to climb it. He said, "Because it is there."
Well, space is there, and we're going to climb it

Both of those look very cool. Dont know if the scan n cut thing would be big enough for some of the goresbut I will have a look at it when im in spotlight.. if only I had a laser cuter :D the water soluble glue idea could be handy.

I had a look at one a couple of weeks ago, I dont think there's any way to direct connect to a PC.
Must be scanned first and then cut, tho I did later read that you can upload an SVG file to their website and it will generate a proprietary file that you then need to put on a USB stick to plug into the cutter. Seemed kinda limited for the high asking price. I also read about cutting accuracy issues.

Edit: Found one http://svgcuts.com/blog/brother-scanncut-review/
The Cameo Silhouette seems to get mentioned a lot and is about half the price, tho I haven't looked into it.
