Help Repairing a Bowl
Apr 17th, 2016 at 10:58am
 
I repaired a large Apple salad bowl for a client. It had small cracks on the rim that we're getting larger. The bowl is several years old and used every day.

I turned the top to flatten out the cracks, sanded and used thick CA with some of the saw dust to fill in the cracks. I then soaked it overnight in walnut because it was very dry.

When they used it, the CA didn't hold so I'm left wondering if I should have used epoxy or something else.

It was the first time I repaired a bowl for someone. Any idea what I did wrong.

Thanks,

Jenn

I would guess that the walnut oil loosened the bond with the CA glue. If they regularly used oil on the bowl, then the oil, especially on end grain may have saturated the wood and again, made the bonding weak. So, if you try again, maybe cut out and refresh the edges, then use a solvent like acetone to remove the oil, then glue up again. I would make extra sure to let all of the acetone evaporate before putting any more finish on it, and that is a day or three.

What kind of finish had been on the bowl before you started the repair? 

I don't think CA adheres very well to wood that has been soaked in oil.  But if that was the problem, then the same thing probably would have happened with epoxy.

Let me start by saying that Apple is prone to cracking.

Typically the oil used in the salad should help to keep the bowl from cracking. I can't help but wondering how they are cleaning the bowl and how it is stored afterwards.

Its been my experience, and I hope your mileage varies, once applewood wants to crack there is no stopping it.

Sometimes drilling a hole where the crack is the smallest with your smallest bit will stop it from checking any more.

Jennifer,

Sometimes the cracks need mechanical strength added.  A "Dutchman" or bowtie shaped insert will make a difference.   

Bigislandengraving.com in Hawaii sells bowties and router templates should you want to try a commercial product.

I would propose that if this cracked bowl has been in daily use, then the material in the cracks is contaminated with oil and no adhesive will bond to it. Letting in a bowtie or butterfly (basically a double dovetail tenon) is the way.
