I’m new to woodturning after 4+ decades of being a “square woodworker” and I discovered how much I enjoy natural edge bowl turning. I have a question about CA glue that I didn’t find an answer to in previous forums (if this has been discussed already, let me know).

I know that CA glue is good for shoring up the bark. Which is best: thin or medium CA glue? I used medium on my first natural edge bowl, but it seemed gummy looking. Will thin CA glue give a more natural look?

Thanks in advance for your responses.

I would use thin CA. It will penetrate much deeper. You probably will use quite a bit, depending on the amount of bark.
Remember though, that CA excels in its static strength, not its dynamic strength, so it would still break if hit. It also should put a bit of a shine into the bark.

That shine is why it is the overwhelming choice as a finish by penmakers.

when one works with CA glue on a regular basis, it is a good idea to keep
a bottle of ” CA Debonder ” close by….. just in case you get your fingers
stuck to your – - – ear or something. There are several brands available.

Very helpful advice. Thanks.

By the way, what’s a good source for CA glue in bulk?

Probably the cheapest I have seen in bulk is on Amazon.

When wood havested in winter sap not running bark supposed to stay on without any glue. Nice rule of thumb but not always the case. I think any CA glue medium or thin you find will do a good job for you just buy what you find locally.

You want the freshest CA can find due to recommended 2 year shelf life by manufacturers. Not sure ever seen a date on the stuff, but my eyes are old too.

I have found that temperature changes in your shop can affect CA more than time. They both take a toll, but I lost a lot of CA last winter when I let my shop hit 40-45’.

I always use poly instead of CA glue… mostly because it’s way less expensive, and that is typically what I finish the pieces with anyway, so I always have some on hand. Thinned 50/50 with MS and let it soak in. Of course, regardless of what you use, you still need to have that ginger touch around the bark when turning to keep it from catching and throwing off a chunk or two :) Good sharp tools help with that more than anything else. I’ve been doing a lot of spalted live edge crotch bowls lately, and those can be a bit touchy.

Cheers,
Brad
