ETM all the cutting is done, I have to remove the 5mm off wood. You said that you used a grider. Everytime I have used a grinder near wood it burns the wood and smokes badly. How did you avoid this? And how close were you removing the wood from the board base and top? There isn't any room for error especially with a grinder!

Blast from the past LOL

When I got back from Japan I decided I was going to build my own boards from scratch, well Im about a week out from pressing my first one. Its been a long road but Im almost there!

Where it all started, drawing it out on CAD (thanks Dad!)


The CNC cut template


Channel routed in the core for pouring 360 degree urethane sidewalls


urethane sidewalls poured into the channel


Sintered base laying over the profiled core


You can see the camber profile here. Rocker between the feet and camber outside with a big rocker nose


#1 core with veneer top sheet


some more veneers I made for top sheets


Testing the press with 60psi in it



The next pics will either be a finished board or a massive fail LOL

I did use a grinder with a 1mm cutting disc taking off very small amounts at a time, yeah it will smoke a bit but thats ok. You need to get all the wood out, go till you see the fibreglass layer under the top sheet and the base (wear a dust mask and safety glasses obviously)

If you are worried just use a spar urethane and paint it on the wood like people do with splitboards

Few crap phone pics, needs a little more shaping, wood removed and seal up.







Less than 2 months till Japan, can't wait to test this out.

Please do the above ^^^

I didn't and it caused the urethane to bubble a bit.
I just got carried away and made the urethane one thick layer straight away. Which caused it to bubble when I sanded it back it looked crap due to the smooth urethane surface having bubbles in it, I went to dig the urethane out with sharp flat tip and thought it would come out easy. As it come off very easy from the base and the top, but its tough as between the base and the top, so I just left it and ran a thin layer of urethane to seal the small bubbles on the surface.
