Homemade dew shield - any advice?
Richard Darn wrote:
Any bright ideas? #1. Black flocking material and staples. #2. Use the one you have for camping, and get one of the black mats for a dew shield.

I got some of that funnky foam but couldn't get it to stick to the surface of a camping mat. The dew shield I'm making is a large diametre, so quite a few sheets would be needed, hence they have to fixed in some way. Thanks, Richard Stick funky foam to a stiffer substrate which will spring into place? I'm not sure what would be best - I've got some very thin plywood which might do, or some 1mm ABS plastic sheet. Either could do it. If you want some, email me - snip snip from address. Cheers Martin -------------- Martin Frey N 51 02 E 0 47 -------------- |

Bit worried black paint might crack and fall on the corrector plate. Any bright ideas? Richard, I made one and after the flock fell off, I painted the (yellow) camping mat black using Joy blackboard paint. Surprisingly, this took absolutely ages (days) to dry but provides a very nice matt surface. I have been using it for some time now with no sign of cracking but I don't flatten the mat for storage, it is permenantly epoxied together. I have bought a can of Plasticote matt spray paint for the next dew shield that I have to make, but have not tested it on the foam yet (it might melt it). BTW, if you decide to epoxy your camping mat dew shield together, be sure to put some polythene or cling film under it so that the glue that manages to get through the foan structure doesn't stick the whole thing to your work bench; There are no prizes for guessing how I know this.. - Mike |

Simpler!
Make a fire...Chuck on somecarrier bags....Smoke the mat above the fire. Then use paper "sealer", the stuff you use on pencil drawings to seal in the black. -- ________________________ http://robert.thegeakes.co.uk/ 51:21N 00:23E "Mike Murphy" wrote in message ...
