I don't know that much about snowboards but I think that is going to be stiff. A 160cm ski with 13mm thick core tapering to 3mm is prob going to be pretty stiff. Just reading back through the thread some of the other guys that have built splits said that you don't need to significantly increase core...

We came across a beer truck accident when we were at uni. Luckily it was in much nicer conditions than wintery swamps.
Someone made a short film about it

the cpm is made specifically for compression moulding. the clr is for glassing surfboards - I think it would run out of the layup when used in a heated compression setup

We had someone lined up to get some CPM in Australia a while back but it never came through. All the suppliers are surfboard oriented. I am using Sicomin SR8500/SZ8525 - it is French and imported by Lavender composites in QLD. Costs a S@**load + $110 dangerous goods surcharge on shipping. That would...

I think it would be way easier to create a polyurethane sidewall on the core before you layup (trough method in the polyurethane sidewall thread). That way you have the sidewall bonded with epoxy to the other layers. If you rout it out later and pour in polyurethane it is only the strength of the po...

the one you are using says 20-30C is appropriate for both part A and B. It recommends 24 hrs at 20C for a full cure.

thanks gav I didn't get that far down the list - kept reading about having to heat part A to 65C and part B to 80C and then keep it heated to cure and it all seemed too hard. It looks like it is available from Adelaide casting/moulding supplies so i might check it out and have another go. Are you us...

thanks for the tips. I used a torch on the second pour and it did pop all the surface bubbles, but they just kept bubbling up from the depths after the flame moved on. I think it is either an incompatible sealer or poor sealing. I also blew the channels out with compressed air a few minutes before p...

Poured my first polyurethane sidewalls today. Didn't really go well. I was using smooth on smoothcast 305 as gozaimas has used (full disclosure is that I bought it 3 years ago and hadn't opened it - probably not ideal for polyurethane, but the air tight seals were still intact on top of the bottles)...

Your other option is to plane the sidewall block separately on the jig. Then once they are profiled rip them on a table saw into the strips that you need. This method is good if you plan to make several cores with the same profile. In production a lot of companies fix these sidewall pieces onto the ...

Sad your planer jig didn't work out well it looks really well built. You need the sand paper under the core to be as wide or wider than the core otherwise when it goes through the planer the edges of the core flex downwards and then you end up with a top that isn't flat and edges that are thicker th...

I use these ramp/soak programmable PIDs from Auber Instruments

They have been effective for me.
My control box has 2 SSRs mounted on a large heat sink.

My old pair of public enemies have amber coloured polyurethane sidewall under foot and then a butt joint to abs in the tip and tail. That was prob to help prevent edge blowouts on rails as the polyurethane would flex a bit. I liked the skis, but can't say I really noticed the dual sidewall design do...

I think often a harder silicon mat on the non printing side and a metal sheet on the printing side. A silicone heat blanket heats the aluminium sheet and then it gets pressed down onto the plastic with graphic sheet on top of it.
