I hope one of you very knowledgeable Funsters can help.
I have bought a piece of 10mm nylon sheet to use as a mounting plate for my newly aquired satellite dish. I've been waiting all week for it to arrive and now it has I an having trouble cutting it. I have a jigsaw but the blades get too hot and melts the nylon, fusing it together again :Eeek:
Is there a secret to cutting this material?
Unfortunately, I don't have a band or scroll saw :(

Wouldn't a fine tooth hand saw go throught it more slowly and generate less heat>

You can do it with a jigsaw, sounds like you have running too fast, use it on a low speed and let the blade do the cutting don't force it.
I would question the use of nylon for the base not sure how well PU adhesives with stick to it, I would have used 2 or 3mm aluminium sheet.

I did check with the manufacturer and they said Sikaflex will bond perfectly OK.

Coping saw for the curves? I know it's easy for me to say as I was a carpenter & joiner in a former life.

You can buy jigsaw blades for cutting acrylic, I think Bosch do some, maybe try somewhere like Screwfix, as said before cut at a slow speed to generate less heat

Thanks Dave, I did exactly that and it is now finished apart from tidying up the edges.
Thanks to everybody for your suggestions. I knew I could rely on the Funster Family again :notworthy2::notworthy2::notworthy2::notworthy2:

Looks like a fine bit of cutting out, if I'm looking for an apprentice I'll know where to come :D

Nylon (66 ?) is hydroscopic and can absorb water which may reduce the effectiveness of the adhesive. On the Permabond site they say:

"Difficulties Bonding Nylon
Sometimes bonding Nylon is difficult because the surface can have a “greasy” feel to it (due to slip additives). Even wiping the Polyamide surface clean with an alcohol-based cleaner will show little improvement as the slip additives continue to migrate to the surface. It is possible to “dry-out” Nylon before bonding – leaving it in the oven at 60°C for several hours or overnight will reduce this issue."

Probably worth doing if it fits in the oven !.

Just out of interest why did you not leave it as a full rectangle with (perhaps) rounded corners? Your rather excellent workmanship will not be appreciated by passing aircraft or perching birds :).

I have to confess, I did think about that after I had started cutting it :blush:
But my initial thought was to make it as the original and once the cutting had started there was no going back. :doh:
