Let’s talk dried glue. I’ve done some dumb things in the shop to which I’ll take the blame every time, but I get more cuts from dried glue than anything else. I’m talking regular PVA yellow glue. I clean up as much as I can when it skins over, but it’s usually the squeeze-out from the underside of a panel glue up or a bent lmination in a form or somewhere I can’t get to it to clean it up with the work in the clamps. It has sharp edges especially where the glue flowed around some tape or a caul.

These little buggers are a huge annoyance. For me, the cut is usually longer and deeper than a paper cut, and as little a deal as it is, they almost always bleed which needs a band aid so you’re not messing up your work. I have more shop time lost due to finding band aids for these than any other injury. So annoying.

Anyone else have this problem? You all probably clean up your squeeze out appropriately though…

I’ve never had a problem with cuts from
dried glue. I am very careful about handling
lumber though. The habit of sliding my
hand over material in the workshop was one
that took a few years for me to break.

I could see that. I’m usually careful with rough lumber but get splinters anyway – but I expect it so I watch how I handle it. After a glue-up the wood is usually milled or surfaced so I don’t even think of it. Slide your hand along a joint when picking up a panel and ouch! ugh.

No, somehow I always get cut on sharp dried glue. It’s really annoying.

You are definitely applying too much if you have squeeze out. The chisel effect shouldn’t really effect you. You can use heated glue to make a bond, but this is shaker. You have to specify more because what you got is what you call shaker jam…

While yellow glue is more of a traditional way of joining wood, the more modern white glue adds to the more tech way. You can do a lot more with more modern glues in this form. Pictures would help…

I disagree with the opinions of the previous poster. If you don’t have at least a little squeeze out, you haven’t used enough glue.

I don’t know what kind of glue AxkMan is talking about but PVA glue is usually yellow or tan and it is so universal that only a few people I know of ever use anything else. About the only white glue I am aware of is Elmer’s and it is just an inferior PVA glue.

I’m using titebond 2. Don’t have any pics of this glue up and it’s all sanded down already, but it was a simple butt joint panel glue up with 2 cauls I made out of 2×4s and packing tape on the jointed edges that came in contact with the work piece. The problem is the packing tape has almost a capillary action with the glue and it makes a sharp edge around that spot where it squeezes out of the butt joint and is pressed around the caul. I very well could be using too much glue, but it’s not extremely excessive. I’d just rather err on the side of too much than too little.

Here’s my cut from earlier today, just took the band aid off. It’s about half an inch long, slid my hand down a butt joint when I went to pick up the panel and sliced my thumb. Nothing serious but very annoying. Maybe it’s just my dumb luck too.

Carloz, hahaha now we’re talkin.

I did find some pics. Nothing out of the ordinary for me here… Kind of hard to see the glue. And excuse the mess.

How is Elmer’s white glue inferior? I use it sometime when I want a little more open time. I’m still waiting for the first glue failure.

I’m not alone either,

Although I’ve pulled quite a few splinters from handling exotic hardwoods and rubbing my hands down planks for possible builds over the years, (wenge comes to mind, nasty splinters), I cannot ever remember cutting myself on a glue squeeze out. I admit, they are there, but I’ve broken off many, and never been cut.

Maybe your hands are still too soft? You need to do a few hours of hand sanding, that will toughen them up!
