Topic tags/keywords: cutting board end grain question

So I just recently made my first three end-grain cutting boards (one for myself, one for my girlfriend, and one to sell), and I am having a problem that did not turn up in any of the online research I did before I started. Here’s a picture of one of the boards. It is about 12” x 18” x 1 1/4”.


The design is one of the aliens from the Space Invaders arcade game.

I used Titebond III and finished the cutting boards with a few coats of mineral oil as was widely recommended online, and when I washed the cutting board after using it for the first time, it raised the grain of the wood (which was more or less expected), but I was surprised to find that the glue lines were raised as well, as if the expanded wood was squeezing the dried glue out of the cracks (which I wouldn’t have thought was possible).

I took my board back into the shop and sanded the whole thing, then raised the grain a couple more times, and sanded it smooth again until the grain and the glue didn’t raise anymore when wet. I finished it with several coats of mineral oil again, and it looked great. I took it home, put it away, and left town for a week. When I came back yesterday, I found that some of the glue lines looked like they had begun to split or pull apart. When I left it, this was not the case, and I am sure it hasn’t been used since. I didn’t soak the board in water when I was raising the grain, but just ran some water over it, and then towel-dried it. The copy of the board that I made for my girlfriend was made with exactly the same process, and has been used and washed a couple of times. Her board also has raised glue lines when damp that seem to go down most of the way when it’s dry, but I have not had the chance yet to re-sand hers like I did to mine, and her seams don’t seem to be pulling apart at all, so it seems logical that this step caused the problem, but I don’t understand why, and would like for the boards to be nice and smooth if possible. I also would have thought that this would have been mentioned as a potential problem on one of the many websites/forums that I checked before I started my project.

I posted a picture of my board on my website, and have had about a dozen people ask if I would sell them one, and I would love to be able to do so (woodworking is a part time job for me, and has provided a little less than half of my income for several years), but I want anything I sell to be high quality, and would not feel comfortable selling them something with this problem. Has anyone had this happen to them when making end-grain cutting boards? Does anyone have any idea how I can fix/prevent this problem on my next set of boards? Thanks in advance for any advice.

i have never used titebond III for cutting boards, but i have made a about 30 with the original titebond, it took 23 trips through a dishwasher for one of my boards to fall appart (wanted to know)

initally i had a similar problem with the glue and the grain rising but i found that if in the sanding process when i was doing the final sanding with 220 sandpaper if i got the wood a little hot with the sanding the problem dissapeared. i dont mean hot enough to burn the wood but warm enough that you can feel it as far as i can tell this seals the pores in the endgrain and hardens the glue to where it doesnt melt as easily when wet.

hope this helps

The glue should be fine but I’m no cutting board expert. Get more advice on that if you are going to sell it. The main point I would like to make, though, is with regard to coronet’s comment: Maybe he was just testing his, but you should never put anything wood in the dish washer.

The same goes for your salad forks and wood-handled knives. This warning should go with any cutting boards you sell. They should only be hand washed and immediately towel dried. Food-safe oil should be re-applied after every few uses or every couple of weeks. This simple occasional care and maintenance is crucial if you want your wood cutting board to last.

A dishwasher is a great way to destroy wood projects. You may as well put your cat in the washing machine too.

I have researched Titebond III, and at least you can take comfort that is is food safe. It won’t harm you.

I make a lot of end grain boards and I had one recently that did exactly as yours. It is walnut and maple. I use Titebond III. I finish them with mineral oil and melted beeswax and put it on the boards while warm using about three coats.. A couple of days after oiling the board I ran my hand across it and noticed that there were ridges at every glue line. I resanded at 220 until smooth and put another coat of oil. The next day the ridges were back. I sanded a third time and they never came back. Now this board never came close to water so I haven’t a clue why it happened unless the moisture content was higher than normal. It is the only one that has done this out of about 50 I have made in the past few months.

As far as the grain raising when wet, I saw this happen with my first couple of boards. I solved the problem with the mineral oil and beeswax and putting a least three coats on it. The beeswax makes water just roll off. I have been using one in my kitchen for about three months, usually everyday. I wash it off in the sink, and it stays smooth.

Hadn’t had that issue yet. I’ve used TB III and it’s clones on simlilar boards. Not sure what the deal is but wanted to post and say that the Space Invaders design is classic! Brings back some DOS/Atari memories! Laughed when I saw it. I’ll expect to see some Galaga and Asteroids in the future??

Second thought, Dennis might be on to something. The moisture content of the board seems like it could be an issue. It makes sense at first read, but what do I know? Good Luck.

Yes, did you have a chance to moisture meter the board before working it? I suppose there’s a possibility that perhaps it was unusually dry beforehand?

After the big Xmas run on endgrain boards, with warping during shipping, raised glue lines etc., I wonder has anyone out there in LJ land made a board with Gorilla glue?

Thanks to everyone for the feedback. Sorry to say that moisture meter is a new term to me, so no, I did not do that. I have however made several more boards since that first one, and have not had the problem with any of them. I am wondering if I might not have let the glue cure long enough on the first one, and maybe it reacted to the water where it would not have if it were fully cured. I let these newer boards sit for four or five days before sanding them to their final state and finishing them. Problem seems to be solved for now anyway. Thanks again!

Oh, and here’s the next design I made. It’s the triforce from the Legend of Zelda game series. Both boards are walnut and hard maple.
