Good tips.
I sealed the inside of the vacuum box by mixing wood glue and water and painting that over the MDF. I will do the same on the top and sides.

I'm off to get some Plywood to do a test run.

I'll let you know.

I have just finished my table and the planner bridge. Phew.. was a lot of work. I'll test it tomorrow. I'll also picl up some ply tomorrow to see what it looks like.

Ok, Table is nearly finished.
I tested it and it holds quite well. Maybe I need a little more powerfull vacuum

Realy nice looking skis Gilo.
I think I will start off with ply cores.. As a learning experience.. and for my first pairs of ski / snowboard they say K.I.S.S.

In the "Community skis" video where I got the idea from, he was saying that the plywood cores give more torsional rigidity.

The bCores look nice, but you will have less wood to hold your screws in than using multiplex. They recommend either using inserts, or adding a binding reinforcement plate as indicated here: http://www.bcomp.ch/files/bcoresd200_process-guidelines-en-orange.pdf I am surprised you were worried about y...

This might be due to half the layers being cross grain which does nothing in terms of longitudinal stiffness in a ski, and you don't really need side to side stiffness. In a proper ski core the grain runs along the length of the ski which helps to stiffen it a bit and probably also make it lighter ...

You reckon?. From my experience the plywoods I have used are pretty good. Probably depends on where you get them. I use Marine quality Birke Multiplex. OTOH I have never pulled a piece apart to see what exactly is inside. But I have never noticed any gaps or knots. I guess I will just have to try it...

Hi all. My Profile table is nearly finished, and I am trying to build some fake cores using pine, so I can polish my technique. I am concerned if I can get a flat surface without a plane.. I might take the bases to the local carpenter or wood seller to get them to make a flat surface for me. However...

Thanks for the advice, one more question. If I do buy the Thomas and need to recondition it how difficult a process is it? It's not too difficult. Though I messed up with mine. If you can get a reconditioned pump go for it. I had problems getting the screws open as they were so tight. I later heard...

I'm located in BC Canada... Hmm, that might be a bit far for a German handler. You need something like this. http://www.ebay.ca/itm/Thomas-2660CE35-111-Motor-600314D-Vacuum-Compressor-Pump-Tested-Working-/161841227417?hash=item25ae7d2699 But you have to find out how much vacuum it pulls. I bought a...

With regards to vacuum, you can't get more vacuum than -1 atmosphere for pressing things. I use a Thomas 2660 pump that I picked up on e-bay, for about €60, and reconditioned for another €60. Save the trouble and get a reconditioned one. Here in Europe you can pick them up for about €120. They have ...

It might actually turn out to be a good thing. A breakthrough in ski technology!!! As you go into a carving turn with your weight forwards, you are using the ball of your foot for the ski pressure, therefore if the camber is located further forward, it will give a more even preasure on the snow. Min...

Or add a layer of UD (Uni Dimensional)
or Un dead
or Utterly Dumb

Sorry, I see there is UD in there

+Thanks for the answers guys. I know I won't get it right the first time, so yesterday i bought some Pine, in the dimensions I will using to make my Ash cores, so I can do a practice run. I am using the router to start with, and at some stage will get a Planer if I make it that far. But I want to st...

Not sure where the best place is to put all these questions so I will start one thread for all sorts of beginner questions. Maybe others can use this as a general purpose questions thread. Question 1: Software. What software is the best to use. I have tried SnoCAD-X, and this looks pretty good, but ...
