"Don't Stress" glue ups

I got so tired of fighting with glueing up cutting boards.
Is everything lining up ? Is there slipping ? One clamp at a time !!
So I spotted these flooring jacks in the HF catalog
...and I began to wonder.
I bet that I could use these to clamp cutting boards together in hopefully one shot.
I haven’t tried it yet, but I will let everyone know if there are problems.
I am thinking this is going to work just fine.
I may need to add regular clamps at the corners, we’ll see.



I did have to modify the clamps a bit so that they function in the manner I intended. They are bolted to 3/4” melamine. I still need to put a protective coat on the cauls, then I’ll give her a try.
The way I have it set up right now is for gluing up a 12” x 16” cutting board-
specifically the woven board which is a nightmare to glue up !

Thanks for looking,

So how are you going to mount the top cauls to keep the strips from slipping up?

The top cauls are bolted to the melamine
from the underside.
Those are fixed, but can be removed
to be replaced or longer ones put on.

Should be a good Idea! How about taller cauls and maybe a degree or two of taper on the face of each for downward pressure?

the only thing i see that i would change is the holes in the melamine.i would insert 3/4 in races through the holes to strengthen up the wood.but that is a cool idea makes the glue up faster and you dont have to keep adjusting a bunch of clamps.i have seen something simular to this but they used pnumatic rams.this looks like a cheaper way to go

There is an accidental taper on the cauls on the jacks.
When I noticed it, I pitched them downward just as you suggested.
I actually shimmed one to tip downward. I free hand drilled the hole for the bolts,
and you might know I don’t have a very good eye for level or perpendicular. LOL
The cauls are 1 1/2 ” tall, I usually don’t make boards thicker than that.
I have two boards waiting for this clamp jig….

Thanks tunk – There is a washer on the underside bolt for surface area strength, and the jack plate on the top. I think it might be strong enough. You may be right though…

Cool idea. It seems like there might be several variations on this theme for other situations. I’m looking forward to hear how it works.

Looks like they will give good, even pressure on the board and ease the pressure on you!

You just had to throw in that bit about the woven board being a nightmare after I just spent the day cutting the pieces for one!!! LOL

Larry (degoose) doesn’t sweat over his glue ups,
You might check his glue up blog.
Sorry to scare you…

Hi Lisa, I’m concerned about how the force is transmitted to the cutting board pieces. I’ve read that the force from the clamps is transmitted at a 45 degree angle eminating from the outer edges of the clamps. If there is too much distance from the ends of the clamps to the end of the cutting boards, like it appears on the long side, the pieces at the far edges may not get enough clamping pressure. I think the solution would be to make the board that attaches to each clamp wider. I don’t know if a curved caul solves this problem or not. What do you think?

Larry’s blog is what got me started thinking I could do it. LOL
I still have a few more narrow slices to cut, but I hope to get back to it tomorrow after dropping the dogs off for their Beauty Parlor Day.

(I, on the other hand have not had a Beauty Parlor Day in years!)

I love your ‘necessity is the mother of invention’ approach. This looks great for glue ups.
I bought these a couple of years ago. You can make them any size you need and they are now on sale at Woodcraft. They are a bit awkward to maneuver initially, but you get 4 sides of holding power. They probably
work better on strips while yours works better on the basket weave.

Lisa, I like the idea, my question though, is, after looking at the teeth on the ratchet, they look like they may be a bit coarse for adjustment, so you may apply too much pressure or not enough, sometimes you only need to tweak a clamp to finish, I guess you won’t know till you try it. let us know how they work.
