Just to add, that any comments or questions are appreciated. I’m looking to not repeat this problem again.

Thank you,

Ummmm….. 0% humidity in New Mexico, 95% humidity in New Jersey.

You also don’t know how the owner cleaned it.

Humidity will make a 16” thick butcher block do strange things, let alone a 1 1/4” board.

If the owner lets the board sit for awhile, it will probably acclimate to it’s surroundings.

The breadboard ends probably didn’t have anything to do with it, except they don’t do anything on end grain boards except look pretty.

I was figuring that the humidity might play a big part in the problem. I just didn’t think about it prior to sending it. I put the ends on the one for more length, since I broke a couple of pieces. I will tell the customer to give it some time, if that doesn’t fix it I will just have to send another one.

I appreciate the response, not really sure what to do if I have to send another one to norther parts. Maybe wait til monsoon season here. I will have to make a disclaimer, ONLY SHIPS IN JULY AND AUGUST. Wonder how that will go over.

Again thanks for the help.

Air drying a board after cleaning is a big factor in warping. A board freshly cleaned needs air on all 6 sides for hours. Such as setting in a rack. Or at least tipped up on one end. If not done, a cutting board will warp most anyplace.

I agree with rustfever above. I will also add that I have seen endgrain boards warp by applying more oil to one side than the other.

More air flowing over one side than the other after wetting will also warp boards. Rule one: whatever you do to one side, do to the other or it will arch it’s back in retribution.

Hey thanks for all your responses. I really do appreciate all your inputs. I will digest it all. I was probably in to much of a rush to ship. Most of my work doesn’t make it to the coasts so I don’t take these things into consideration. Asking for forgiveness doesn’t always work for customers. Luckily I have other boards I can ship them if all else fails, I would probably just refer them to someone in their neck of the woods next time. Doesn’t make sense to take the risk if someone closer to them can do the same thing. Plus shipping is horrendously expensive now a days.

Appreciate all your responses,

Arching ones back is not always a bad thing, but point well taken.

I have made several end grain cutting boards and sent many of them to NJ to family members; none have ever warped. I doubt humidity was the culprit. Sounds more like someone got their board very wet and just let the water soak in or even worse, put it in a dishwasher.

Doesn’t sound like any of the issue is related to your construction or finishing.

I haven’t made a lot of boards but I use the same principles as any other project so I guess I have to question my technique. I did do a lot of research, mostly from the talent on this site. SO I do feel my techniques are solid. But with all the variables involved one can never be sure. All being said, I will continue building as I have been and consider this a learning experience. Kind of like Basic Training only with out the marching and yelling. I do question the customers complaint and or truthfulness but who am I to repute their morality. I have to question both my techniques and their truthfulness. Either way if the customer isn’t Happy, Happy, Happy, neither am I. I will take all into consideration make adjustments to any technique that may need it and drive on with my bad self.

I do appreciate your confidence,
Thank you,

Either way if the customer isn’t Happy, Happy, Happy, neither am I.

That is an excellent work ethic I try to live by.

Most of the time I will just eat the problem and give the customer a new piece. I also pay for shipping both ways, so I can have the old piece back to see if I can tell what went wrong.

Sometimes it’s me, sometimes it’s materials and sometimes, (gasp), it’s a customers fault.
I don’t say anything, just check mywork more closely or check the material more closely, or put that customer on a “Do Not Sell To” list.

Bill, I am sorry about this mis-adventure. I sent my son a CB from ABQ to DC. If he cleans it and lays in on the counter, it warps. When he flips it over on the counter it flattens out again. Now, he leaves it on edge after washing until it is dry and it is okay. I suspect that eventually, it will totally adjust to their humidity level and it will stop misbehaving in this way. Maybe you can send your customer a box of green chiles as a piece offering. :)

By the way, great looking boards.

I’m not sure if this is a viable option or not, but if you wanted to acclimate your boards before shipping them to a known humid area, here’s a trick from my old cigar smoking days. If you mix a bowl of table salt and water into a slurry and put the solution into a sealed container, the relative humidity inside will stabilize at 75%. I used to use this process to calibrate my hygrometers. Here’s a link if you’re interested:

If the cutting board doesn’t have feet on it, a damp counter top could have been the problem. My wife left her’s set over night on a damp counter top and in the morning it looked like an end grain bowl. A couple hours in the oven- at the lowest temp- flattened it back to level. After that, I’ve installed feet on all my cutting boards.

Just my 2¢

I also put feet on the boards I have made. The rubber ones from woodcraft work well and make the board sit well and don’t slide around. When I clean mine I wash the side I used then rinse the back so both sides get wet. My though is that it will equalize the water absorption, haven’t had a problem yet.

I figure if it not a great big deal then it’s not worth the headache. I like the no sell to list, “NO SOUP FOR YOU”

Not a bad idea, who can argue with Hatch Chili’s. I always dry mine on the side so I didn’t even think that everyone else in the world wouldn’t do it the way I do, who knew.

really nothing is off the table if I can figure out how to fix the problem. I try to look at all options available to me so I will definitely look into this thank you for the link.

Truthfully I’m not a big fan of the feet some reason I just don’t like them. Not that it would be off the table if that happens to fix the problem. It does bring me to an idea about making stands for them and selling them as a set so they have something to dry them on.

I always seal my boards with GF salad bowl finish. It’s a varnish, basically. Also use rubber feet on the bottom.

Anyway, it does a great job of sealing the board completely. Do both sides equally. I’ve never had a board warp, but there’s always a first time, I suppose.

Leaning here also as mentioned by someone else that you don’t really know what the one board was subjected to. I did have my daughter-in-law call me once to tell me that one of the small test boards I made for her 2 years ago cracked. After some questions about how she stored it, she finally told me she had put it in the dishwasher every week to clean it. LOL, I was surprised it lasted as long as it did.

My daughter doesn’t even know what a dishwasher is, oh wait it’s me, so count yourself lucky.

You don’t say when you shipped these boards, but the northeast in winter can be as humid as the desert, so the 95% comment is simply inaccurate. Did you test your wood with a moisture meter first? Friend of mine made her first batch of cutting boards and they all warped – she didn’t know how to set the meter for the ambient temperature and she thought the wood was dryer than it actually was. After she figured that out things went much better. Just a thought.

Have your say...
