Repair a Cracked Bowl Blank

Duration: 4:21

If you’re a woodturner, CA glue is one of your best friends. It’s perfect for doing spot repairs on your bowls and spindles. There are a variety of viscosities of cyanoacrylate glue available. I typically use medium or thick for these repairs. Accelerator for the glue isn’t a must, but it’s handy to have.

In this case I was turning a three-cornered bowl and was pretty far along in the process when a weak spot in the bowl blank showed up; a split right along the grain. Instead of discarding the bowl, I grabbed CA glue, accelerator and some masking tape and started the repair.

Sequence of Events

If you’re using an accelerator, that should get applied before the glue. Accelerator has a long open time, CA glue has a short open time. So it makes sense to apply the accelerator first. You should also be careful about how much accelerator you use. If you’ve used it before and seen your CA glue crystalize, that means you used too much accelerator. This weakens the joint.

Spritz a little accelerator into the bad spot in your bowl blank, followed by applying your CA glue. Have masking tape (this is your clamp) nearby so you can move quickly once the glue is in place. Use the tape to “clamp” your repair, and in a few minutes you’ll be back to working your wood bowl blank.

    I have also used my shop vac to pull the glue through the project. On one particular bowl I was refinishing i could tell by the sound there was a hair line Crack, with the shop vac I was able to draw the glue threw the Crack.

    Do you know if the glue goes chemically in contact with food? Is it safe to use such glued bowls for liquids and food in the future?

      Hello Daria,

      Here’s what the experts had to say about your question:
      If the glue will have contact with food, be sure to use a glue that is FDA approved for food contact. I do not believe that CA glue is considered to be safe for food contact. Titebond 3 is a good choice for this.
