I am recarpeting my trailer bunks on my ez loader trailer for my zx250. The back end of each board has a 45 deg bevel cut on each 2x4. I cannot access my old bunks as I need them still on the boat trailer. Can anyone please send me pics or patter on how to cut these for the 45 degree end. I have tried everything. The rest of the bunks are carpeted. Im just waiting on completing the ends.
