Advice needed about my planned cabinet please
Hi all, I am after some advice about the cabinet I plan to build under my router table.
First off is my confusion over timber sizing, 1/4 inch ply isn't its 6mm , 1/2inch is 12mm and so on up the range. Over here in the UK we are metric so I understand that but is sheet thicknesses reliable because I can find various cutter sizes 6, 6.3,9.5,10,11,12,12.7 to name a few and the list goes on. Is the choice available because board thickness alters or is it just for extra choice. Do I need to buy lots of cutter sizes because boards alter?
If boards are reliable thickness is the choice for different fits?
When It comes to making my cabinet and rout out for lets say a shelf made of 12mm ply, would I rout a 12mm rebate or make it slightly bigger ie the 12.7mm cutter? Would the same be true if the shelf was mdf.
I'm guessing all joints should be as tight as possible hence my confusion.
Many thanks in advance, Cheers Si
