I’m looking to make a couple of simple oak tables and I’ve purchased some fairly cheap off cuts to make the table tops . I’m aware of alternating the growth rings to prevent cupping but some of my off cuts don’t seem to have a definite direction. My question is will it make any difference where I can’t make out the direction of the rings . Secondly I’m planning to use biscuits to join the strips together and I’d like to know if I should apply glue to the slots and biscuits or or just the slots . Will try to send picks when I’m back home /thanks lads and lasses.
my recommendation is dont bother with alternating growth rings -just select the best face of each board
glue up boards leaving them well over length
biscuits are important to stop slippage as the clamps are tightened -but TBH they dont really need gluing in much if at all
when youve set your boards out, mark them 1, 2 , 3 etc and if you like draw 2 diagonal lines across the boards -sort of like a giant Vee -its easy to see if the boards go together in the correct order.
if the ends of the top are seen make sure the biscuits are well away from the
when you come to glue up, lay the set of boards out as they will be, then starting at the front flip each board so they end up on edge -leave the last on laying down. Then glue all the edges facing up. bang in biscuits....
PS -always get your sash clamps to the right position before applying glue
always sash clamp both sides an dcheck with a straight edge that its flat
make top a bit wider than necessary so any clamp pressure marks can be removed
finally -be careful with steel sash clamps and PVA glue on oak, if you are messy with the glue and it gets on the clamps you might get a black stain mark.
wipe off / scrape off as much glue as you can whilst wet or tacky
