Moisture cure urethane will protect the edges of the topsheet and the laminate.
Leaf skis used a polyurethane and it worth considering.
Oil and wax ... fairly pointless.

MM, I think you mean previous evolution of mongo press have been poorly built. Unlike this one:

80 psi??? Somewhere between 40-60psi

Greeting ) Just need to checked whether you have seen Chrismp's press. Quite possibly the most effective design - just missing a thermal cover ) Enjoy: https://vimeo.com/60566948 And there are a couple of factory video's with this type of press design: http://skibuilders.com/phpBB2/viewtopic.php?t=3...

Ryme, Are you using epoxy mixed with teak oil? Or applying epoxy then teak oil? Does teak oil polymerise over time? Paraffin wax is the best wood sealant. I don't have the technical paper to hand, but its better than most other products, surviving the seven day immersion test. Personally, I mix it w...

The terminology I've added should help narrow the issue and enable a bit of reading and such like. CTE of carbon and glass fibre, spring-back/forward are all discussed on the web, as are the do's and don't for finding a solution. The trick is to ignore the maths, pick-up on the main points and reach...

Before you do anything, take it outside in the snow and confirm the size of the error. You will need to let the ski assume the ambient temperature before taking a measurement. Overnight would be good. Some of this maybe process, but its due in large part to the relative coefficient of thermal expans...

If the motors and drivers were cutting aluminium on another machine, I don't see why you should think they won't on you design. The rails you have are made of solid stuff, this is above the minimum I have seen used on large format machines cutting deeply into 2 inch aluminium plate. Take a look at J...
