Well, I think I'm ready to glue sets of 3 3.5" boards for my intro project
to make the sides, top, bottom, and shelf. I think I understand the
basics - apply a healthy amount of glue to each adjoining edge (enough glue
to where just a bit squeezes out when clamped), clamp about every foot of
so, and let dry per mfg specs (preferably overnight, if possible).
Any advice of tips on gluing the butt edges (I've decided to follow the
majority of the advice here and pass on the dowels, by the way)?
On scraps suggest try two things, (1) "healthy" amount to see what
this quantity is as I'd expect you'll get more than anticipated and
(2) try the brads into one edge then cut off leaving a sharp point for
aligning the other board. On longish assemblies alternate clamps
above and below to avoid cupping from clamp pressure. To help this
approach I made a couple of supports to set the glueup on from scrap
3/4" ply with plastic glued to top edge to avoid glue sticking to
I would suggest a dry run, try clamping the assembly with no glue; the edges
should close perfectly. If they don't, plane them until they do. It is
best if the edges meet first at the ends of the boards so that the clamps
can bring the middles together.
I don't think it makes too much difference whether
or not you use biscuits. I have done it both ways
many times and you will be ok either way.
I would definitely "joint" the edges before
you glue. Be sure there are no visible spaces
between the boards - don't rely on clamping pressure
to try to squeeze them together.
Plane the boards to the same thickness to avoid
excessive sanding later - don't assume they are
the same unless they came from the same long board.
If you are using pipe clamps (which I do), I place
wax paper over them where the pipe may contact & stain the
Alternate clamps (top/bottom). For your 3 boards, you
prpbably won't need a caul, but it something to keep in
mind if you ever do bigger glue-ups.

I do have a few hairlines of space between boards when I hold them up to the
sun. Worth waiting another 5 days until I can try jointing them again at
class (I'm kind of falling behind, by the way - there are only 3 classes
The pieces are from the same long board. But there still is a little (very
slight) thickness variation. I'm hoping not too much that I can't just sand
out once glued up.
If one board has a slight bow (maybe 1/16" across 30" of board),
could/should I run it through the face through the jointer (these are only
3.5" boards) instead of a planer (don't think I have access to a planer)?
I just found out the hard way about the clamps touching and staining the
wood during my dry run. I won't lay the clamps across the wood now. I
don't have pipe clamps. All I have are the "quick clamps" that have the
Not sure how to go about alternating top and bottom. If I have a clamp on
bottom, won't the panet "sit" on these bottom clamps? I'm having trouble
envisioning how this would work. I get what you're saying conceptually,
just not visualizing it. I'm also not seeing how I'll keep the boards flat
across if I'm trying to put clamps underneath too. Won't the pieces shift
around while I'm switching from working on top and bottom?
Hi (again) Corey,
At this point, I think you have more information
than necessary to glue-up a few boards.
Try it and use whatever hints that
seem right for your situation.
Remember to have fun-that will keep you

This isn't necessarily true. In fact, I've read in more than one place
(Kelly Mehler comes to mind) that suggests to have just a slight amount of
space toward the middle of the boards. When clamped, this creates
additional tension at the edges where a glued joint would be more likely to
fail. At least that's the theory. Personally, I joint them flat,
I noticed this with my black pipes. This weekend I went out looking
for the extra clamps that made up enough to clamp a plant stand
together. In my searches I stopped by Rockler and found that they
sell zinc pipes that seem less likely to discolor the wood than the
black pipes. Sale price was $60 for 4 3/4" pipe clamps with 3' zinc
Rather interestingly, these cost the same as pony clamps and black
pipes from Home Depot, Menards, and Woodcraft. When I searched
the wreck for the Rockler clamps, they seemed to be liked just a
bit better than the traditional pipe clamps.
