Thanks Nebbian, I think I'll just buy one like Mr nobody's unit. Thats what I've been trying to find for a while now. $200 is a small price to pay when you consider that with my electrical skills I would probably burn my shed down trying to build one.
Thanks for the pics and info.
I made a hotwire using 0.8mm Stainless Steel MIG welding wire, the power source was a welding machine.
Welding machines are set at a max 70V open curcuit so they are safe.
You can vary the amps from 0 - 130 on a small machine, worked great.
Went to altronics today looking for the same unit Mr no one had. Ended up with a 15volt variable power supply for $45.00, stoked.
Cut out 2 blanks with it this arv and it works really well.
Thanks for the info
Top score Hoop, got to be happy with that
.
Well, looks like my work here is done, UP UP AND AWAYYYYYYYYYYYYYYY.
It goes from 5volts 5amps to 15volts 3.8 amps. It just has one dial to wind it up or down. It's a basic little thing but it seems to do the trick pretty well.
Just a quick question??
what kind of foam are you guys using for the core and what density id it?
and where do you get it from?
thanks
oh and I am based in Brisbane so have you got any ideas to get some?
Jamesy ,the foam is 13kg /m3 polystyrene. Just look up foam in the yellow pages ,it shouldnt be hard to find. Not sure what density others are using but this seems to be fine.
Years ago I bought a big block of 24kg/m3, because all my boards then were going in waves, and I have a habit of landing big jumps flat.
But even so think it may have been overkill.
Just about at the end of the block now, my next boards will probably be 13kg/m3.
