Hi,
I am enclosing 2no 19mm x 100mm western red cedar tgv in a 50mm x 65mm frame. What do i have to allow for expansion of the tgv? or do i not have to worry about hat because the grooves in the tgv already allow for expansion. The tgv will be sitting on a rebate within the frame.

Thanks In advance
Simon

Update:
For anyone who might be interested in the answer. I found out today to leave a 1mm gap both sides of the tgv for expansion.
