WDJ - Building tip

Hello Fellow WDJ Builders (getting started, Ian and Jack?)
 
After a long winter with little or no time to build the plywood in my basement finally was cut to many pieces. Afterdeck rail stanchions, stem, bracket for the drag link and leeboard bearing boards: all cut and laminated.
The leeboard bearings are supposed to be cut from 1/4 inch Nylon sheet. After several phone calls to firms in Oslo I ended up with the option to buy a sheet of nylon, far to big for my purpose, to the prize of NOK 2300, abt. USD 350!
 
So here is my tip: I bought plastic cutting boards from IKEA, NOK 19 a piece (USD 2,50). I guess I will need 17 or 18 of them = USD 45 total! The boards I found are 10 mm, a bit heftier than PCB recommends. Shouldn't make my boat sink.
