   One of the hard things about repairing cracked bowls is to close the crack. It i hard to clamp most of the time. For this reason, it is nice to have a really fast setting glue. If I am doing a turning that may have a check already in the wood, or maybe I let it dry too fast causing a small check that I want to repair, I like to use CA, or caynoacrilate.

   If you have never used CA glue, it can be tricky, in that it is so thin. If you can hold the crack closed and hold it in a position so that as you touch the tip to the top of the crack, it can run down-hill toward the rim. Capillary will draw this thin glue into the crack, and if you have the accelerator, and can give it a quick spray, you will see it boil within about 10 -15 seconds. If the crack needs a little filling you can sand the surface some, then hit it with another shot of glue, and sand some more while that one kicks.

   Be sure to do this with good cross ventilation. The fumes from this glue will really burn your eyes, and it is pretty easy to get it on your skin, and getting burned.

   What Keith said. It's the perfect stuff for your problem.CA glue comes in three different viscosities; the thinnest is good for hairline cracks, the thicker stuff works a treat on larger openings. All three have extremely low surface tension, meaning it will pull itself into cracks and openings. The accelerator is key - it will cause the stuff to set up hard in seconds. The big drawback is the fumes, which really are nasty, and you can develop a chemical sensitivity if you use it regularly."Everything should be made as simple as possible, but no simpler."  A.

   sounds as though this is the solution I was looking for. Is  CA glues food safe ? Thanks for the info. This bowl is very old. about one hundred as near as I can tell and would like to keep using it. Thanks again

   Good question since you may have this thing glued to your hand for the rest of your life. Kidding I hope. There are better more qualified places to ask than here. Here a couple of links.http://www.e-zbond.com/Product.htm

   Barney,

   If the crack goes all the way through the bowl, you can persuade the glue into the crack with a vacuum cleaner, then spritz with accelerator and it'll set in a jiffy.

   If the bowl has enough curvature, you may be able to close the crack after you've applied the CA, but before you apply the accelerator, by using a few well-placed spring clamps:  the ones I'm referring to are commonly used when gluing-up miter joints, as when installing crown moulding or assembling picture frames; they have very sharp points that you spread apart with a tool supplied by the manufacturer.

   Good luck,

   Thanks for the info. Will try that. It should not be that dificult. I'm still concerned about the safety of food after using CA glue. Ihave not been able to find out any concrete data as yet

   What about epoxy?-Jazzdogg-
