biscuit joiner

Recommended Posts

Hi,

I just bought a biscuit joiner (Cordless MakitaDPJ180Z)  and im looking to join 3/4 inch ply on a 45-degree angle... what size biscuits should i use?

And how do I figure out what sizes to use on future projects?

Many Thanks

I use size 20 for gluing up boards. The size 20 is probably too big for the 45 degree join.

I've never done that join with biscuits. Do some test pieces to see how deep the slots go. Size 10 is a  bit smaller though.

Youll just have to test it out on scrap. Id say use the biggest one you can fit as long as it doesnt get too close to coming through the other side of the piece.

I made a gauge. I cut every size slot along the edge of a board then ripped the board to just leave the slots and the wood behind and between them . The depth of your slot at 45 degrees is dependent on how far away from the point you can set the fence. Set the fence and check it for parallel to the base of the tool. Even a slight bit crooked will affect a 45* corner. Like Shep said test on scrap !
