6'x6' MDO

[juan45215]

We are replacing a 6'x6' MDO sign. We haven't taken it down yet, but I can tell that it is a 4'x4' attached to a 4'x2'. I have called a few lumberyards, but no one has 6'x6' in one piece.

Does anybody have an idea to fuse to pieces of MDO together?

scab from behind?

For a permanent solution that is smooth on both sides I slot then spline the seam. Hardwood spline plus polyurethane glue. No compensating for the "scab" on the back when you go to mount.

I use this slotting cutter: CMT 822.364.11B

ah yes. spline joint.

you're best bet is the seamed panel... can make it out of 1-4x8sheet, even.
I've also been known to do oversized MDO, by using twice as many sheets of 1/2 thickness of the desired product, and stagger the seams in the two layers before screwing/bonding together.

most of the time, however, I just wrap the individual panels and leave it up to the install guys to worry about joining them during install. MUCH easier to get from shop to site.

LOL. You could get rich off this.

Thanks everybody. I'll let you know how it turns out.

either buscuits or if you have access to a table saw and dado blade, lap joints would be ideal, you could assemble and glue on site.

I would use a wavy scarf joint but I have a cnc

Wow that sucks. I had a pita time finding a 5x10 in Houston 2 months ago. I would just make joint withthe router and then fill in the seam and add a glossy coat.
