Oh and I want to say a MASSIVE thank you to all of you people on this site. It can be very rare to find people so happy to openly explain things that they themselves have had to struggle through to find answers. I could not overstate the assistance you have all been or the gratitude I have. Without ...

Oh and the press isn't huge, that mold is just a short mold for a sandboard. We don't get a lot of snow here but we got heaps of big sand dunes so I'm making a small snowboard (edges, base and everything) so I can hopefully test ride it on some dunes and see if it delams or falls apart in anyway. I'...

Kampai Custom

I've been loitering around the forums for a while and am slowly getting my gear sorted so thought I would join the ranks on here with a Journal. I haven't decided 100% on a name for the boards yet but Kampai is the current leader, I love Japan pow and love beer so seems a pretty good name. I finally...

There are definitely some talented folk on here. Pretty hard to go next after the house extension and a hand built Mandolin but anyway. Build all sorts of things, cars, boat trailers etc but one of the more fun hobbies is building custom bikes. Great fun riding from pub to pub along the river throug...

What is the temp just above the surface of the ski during your heat treatment? What are you trying to achieve with the heat treatment too?
Those blisters look burnt in those pictures?

I would have to lean towards good structuring suited to the conditions and a wax job that also suits over a sintered vs extruded base. Obviously both bases structured and waxed the same the sintered will be faster hands down, especially that Volkl VRL stuff, that stuff is nuts. I have seen some pret...

I think the watts per inch is the important part to heat the laminate in a resonable amount of time. My blanket at 200cmx35 cm is 1400 watts. Takes about 25 min to get to temp. The mei one i have pulls the same amps but get to temp in about 2/3rds the time so obviously they made it better than mine...

Hey is anyone on here using blankets of around 1000 watts? I've been playing around with different circuit layouts. I won't be doing any sublimation with it and I don't want to build something that heats up in 5 minutes while drawing 8 amps per mat. So I was aiming for around 1200 watts but the best...

I made a simple slide through flame treatment set up. Had to make two small burner bars. I figured having the finished base slide onto only 3 bits of tube the damage from sliding onto these should be minimal. So far the test pieces have been promising. I can adjust the flames up and down so when I g...

yeah a negative cutter tooth angle will produce downward pressure.
Another way is to use a cutter with a positive entry angle, like a 45 degree cutter, you also get other benefits too, like increase surface finish quality and feed speed.

I use one old house dyson vacuum and get heaps of hold down.
Use small holes not a channel and use the mdf with coated faces like used in cupboards. The plain mdf is very porous and loses vacuum out all the sides.

I'm just building my control box now and am fitting a 10amp circuit breaker with a built in 2 pole RCD into each blankets supply circuit. The earth is set up pretty much exactly the same as Vinman described. Remember a RCD (residual current device or also called an earth leakage breaker) only monito...

Mate 3amps is only good for about 700 watts at 240 volts.
What sort of watts are your mats good for? You might need bigger fuses.
Unless you built your mats for only lower temps. I'm going to keep mine to about 1400 watts each.
