Plywood split board without glassing is feasible (I have one for 3 years now).Costs USD75 because of the stainless steel screws.
Be Careful on those SS screws . the chinese like to sell the
ones they call SS but they will rust in water.
The way to tell, is to place a magnet next to the SS screw ; if it isn't attracted
to the screw, then it Really "Is" SS.
I had a guy tell me the way he found his T-nuts in a board he made, was to
magnetize them, by wrapping a wire around them and adding current from a battery
Later he would then drop iron filings on the deck of his new-made board to find the
T-nut later .
A Good quality SS part will NOT be able to get magnetized !!!
