I'm making several 15 foot counters that are to finish at 32" wide.
Not having a supply of 15' boards, I'm forced to butt join some of
them as I assemble and glue up the panels. It's quite an operation
trying to even glue half of that panel together before any ordinary
glue sets up. I'm probably going to go with epoxy. IAE, what I'm
wondering is if there's any sort of barbed connector that I could use
to butt-join the ends of the boards. I envision drilling a hole or
two in the end of each board, sticking the TAMB (thing-a-ma-bob) in
one end with some glue, then shoving the other board into it and
having it stick snug without clamping. Sort of like a domino or a
biscuit, but that doesn't require clamping. I feel like I've seen or
heard of something like this before....

Thanks.

So you want to join them and then carry them round at 15' long, 32" wide?

Good luck...


Can you use the butt connectors that are used for joining kitchen
worktops? You have to route out the right shape slot first, but jigs are
commonly available. Once you have the jig, the connectors are only a few
cents each and you can clamp it together on site with a joint as good as
glue.

*But* you can carry it there without dinging it as well.

These should work.

half lap the end-grain joints. Glue up the 15 footers first, then
edge joint the panels. Or use finger joints like the paintable moldings.

You're looking for 'dog-bones'. A 1/2" straight bit and 3/4" bushing
and a simple template. Don't go too deep.

Then biscuits for alignment and lots of good glue.

You still can't lift this whole thing without bracing it first.

Don't use those too close to an edge.

The kind of hardware you're talking about is standard in the PLUMBING
dept -- a 'double barbette' connector for various diameters of flexible
plastic/rubber/etc tubing. I _wouldn't_ recommend using them for wood
working.

If you _really_ want to do the way you describe, the "classical" method
is to use dowels -- just like any joint on shorter stock. More on this
below.

The alternative is to use 'invisible' joining hardware. A dowel-type
hole drilled in the panels, with some _large_ (circa 1-1/2") diameter
blind (flat-bottom) holes drilled up from th bottom surface.
A section of threaded rod goes in the hole, with washer and nut(s)
added to each end, through the blind hole. Tighten to suit. For
stability, use a a 2nd jam-nut on each end, or some lock-tite or similar.

This approach has the advantage of flexibility -- the panel _can_ be
disassembled at a future date, if necessary. 7-1/2' sections also go
around corners, and through doorways _better_/_easier_than a single 15'
long section. Subject to where 'other stuff' goes, I might make it as
3 five-foot sections for that specific reason.

The secret is in clamping up the joint. You _don't_ have to have clamps
that run full length of the stock. See the ASCII 'art' below. Clamp
(_firmly_, with a reasonably large C clamp) a couple of medium-thick chunks
of scrap stock (one on each side of the counter piece) near the front edge
of _each_ panel, a few inches back from the glue edge. Do the same near the
rear edge of the panel. Now, use pairs of bar clamps "above _and_ below" the
panel at both the front and rear -- using the above scrap-stock blocks
as the purchase points -- to pull the dowel joint closed.

Maybe one of these biscuit substitutes?

If this is only temporery and can not be seen have you thought of making
some staples to the right size and nailing the boards together with them?
Another Idea is to take a dowel and drill two small holes in each end at 90
degrees and inserting a small piece of wire in each hole and driving it in
to hole in the wood, sort of a like a dowel joint but with no glue. neither
is very strong but good for a temporary fastener.

That's funny that you mention that - it's exactly what I came up with
myself, but haven't yet tried. Having discovered that it's ok to have
a not so perfect bottom to the counters, I used Dominos and pinch dogs
at each joint. But I may yet experiment with what you mentioned.

Thanks to all for the responses.

That's exactly what I was looking for. Thanks much, Jim.

What about creating an oversized tongue and groove and then using screws
from the underside - at an angle in opposing directions - to help hold it?

*cringing & ducking, waiting for the resounding CLAP as someone whacks me on
the back of the head*
I doubt you could carry them like that but you might be able to join the
like that on site if you had them all layed out first.

The Powers That Be want monolithic tops - otherwise I'd definitely be
gluing up in shorter lengths. Designers...feh!
