Railbands. Looking at the "simple rail dims chart", it displays one single value for rail mark. Do I have to use the same rail mark on all the board length or shall I multiply by dimension as far as I go further or backward on the board?
Each board can be a little different so don't be afraid to adjust the numbers slightly to account for the rail thickness you desire.
