Similar to the cnc finger joint--i posted these pics and the technique back in, wow, july 2006!

Using the template from a harbor freight dovetail jig:
Image

Here is the 3 piece joined sheet that covers the top layer of my trailer (a 13 foot completed sheet). Also note the orientation of the 4 foot panel to aid curve bending on the short side:

Image

That's 1/8 inch luan using epoxy, but any glue could be used. One key is not dry fitting before you put it together--you will destroy the fingers if you try to take it apart. You stack the two sheets on top of each other, offsetting one sheet for the half finger, and being careful to make sure the finished, joined sheet will have the finished side on the same side (if that is of any importance), so you stack with the finished side or the rough sides facing each other when you make the cut with the router. This technique will work with any thickness of ply.
Still graced with two eyes and ten fingers (due in no small part to luck!).

Just when you think a problem is solved, an uglier result replaces it.

TonyJ,

I think you were onto something way back when, we just didn't know it then.

Do you have a link to your original post?

Found it--appropriately titled "alternate plywood panel joint."

Oh, man. I sure wish I'd found this thread a lot sooner. I'm building a 5x5x10 Benroy and had a heck of a time finding 5x10 sheets of plywood. In fact, all I could find were sheets of 3/4" exterior grade. Is it my imagination, or is the exterior grade a LOT heavier (not to mention more expensive!!! :shock: )than other plywoods of the same size? Sure as heck feels like it. I was looking for 1/4" sheets, but couldn't find anybody that carried it, nor would be able to order it, so wound up with the 3/4". All of which caused a rapid re-evaluation of exterior and interior skinning. :cry:

For those of you in the Dallas / Fort Worth area, there's a great place in Fort Worth for all kinds of hardwood and softwood plywood, and bending luan and bending birch. Plywood Company of Fort Worth. http://www.plywoodcompany.com/application/home/main.aspx Their prices are posted on their website, and the guys in the warehouse are awesome about going through an entire stack of whatever wood you need, so you can pick which sheets you want. When they found out I was building a TD, they made me promise to bring it up there when it was done so they could see it. :lol:

I got my 3/4" 5x10 Plywood for my walls from the same place, they were super to work with.

2bits, did you get the exterior grade stuff? Is it just me, or does that stuff seem a lot heavier than regular plywood panels? I swear, these darn things weigh a TON!

Maybe it's just the fact that their "oversized", and bulkier to move around by myself... :thinking:

I know I got the best one and the right one, so if there was an exterior grade, I would have gotten it, but I can't recall. They did seem heavy, but not more than I would have expected for the extra 2 ft of length honestly.

Stretching your plywood...just 1 technique

Postby aggie79 » Thu Apr 19, 2012 6:03 am

Lena,
I purchased almost all of my plywood from them. (It would have been 100% but they're not open on Saturdays). As you said they are very friendly and as Thomas said they have a multitude of products. Plus their higher quality products blow away the BORG stuff.
Take care,
Tom

That was a large part of my build: Sourcing materials like aluminum, wood, trim, the axle, etc. Then once you've done the research and you know where to get the stuff, it makes the build so much easier on #2 !
