Glueing plywood together?

Postby TAILGATINGnNUT » Fri Aug 13, 2004 7:09 pm

Mike I saw that you said you glued two pieces together. How is this done, I called the local lumber yard and they want 130 for a 5'10 piece of ply. I alos noticed that you trialer is done in particle board , I know it's just a mock up but couuld you realy do that?

There's a couple ways to glue two pieces of plywood together...

You can use biscuits and a biscuit joiner... I put in about 5 biscuits along the 4' edge... I would fill the joint with epoxy filler and then paint, so you're not going to see a joint.


The other way to do a joint like that is to use a router and make a rabbet. Let me see if I can find Steve F's link... okay, found it... Steve talks about scarfing, and then about the half lap joint. The half lap joint is the one that I would do given the choice...

You may be right that bisquits may be eaiser..but a bisquit joiner is a dedicated tool..and unless you can borrow one or rent it..it may gather a lot of dust on the shelf before you use it again...a router is in a way is a muliti purpose tool..and if you dont own and dont want to buy one..a lot of people have them laying around gathering dust..and a rabbit bit is not that expensive..just a thought

Tom Where are you in Albany? I live in Broadalbin and work in the Albany area....In consruction(building automation) commercial/industrial.
I would agree that, unless you have regular use for a biscuit machine, you would be better off with a router. The layout and machining of the half-lap joint is very easy, just measure carefully, cut slowly!

Try a splice

What thickness is the plywood?
For ¾” you can use a router and a ¼” slot bit. To cut a slot in each edge 1” deep of the pieces you want to put together. Use a piece of ¼” plywood 1 ¾” wide as a spine. Use a good waterproof glue “Gorilla Glue ” and the splice will be stronger that the plywood around it.

Not a "biscuit", rather, a "fettucinni" joint! :roll:

Spline would be my suggestion for strength and a good seal. An inexpensive biscuit cutter is also great for your cabinet frames too. And I thouight another name for a long biscuit was a hot dog bun. Alan
