Brilliantly Stupid

So I was turning this walnut bowl, and the blank that I started with had some minor cracks in it. Once I got it roughed out the way it wanted me to have it, the cracks were a bit more obvious than I anticipated. I started to fill them with some thin CA, but I don't have the CA hardener spray, so I had to wait a while for the tiny puddles to dry all the way.

I'd fill the crack, then leave it to dry for 20 or 30 minutes, then come back and put some more in. I wasted a lot of time on it. Then it struck me. If the CA in the crack is wet, and I rub some fine dust into it, then put more CA on that, it'd fill in faster, dry faster, and probably look a whole lot better. I felt like a genius for a second! Then I felt like a dope , because this is probably what real turners always do.

I thought I'd share my story to see if this is how anyone else does it, or, on the off chance a new turner also didn't know about it, maybe I'd be helpful.

complicated??????????

I don't want this to sound too technical, but

When I'm turning a particularly nice piece of burl, and see a small crack or two, I almost always fill/line these cracks with Turquoise bits, small nuggets and dust. Line the inside of the bowl with duct tape. start lining the crack with turquoise bits and the medium thickness CA until the crack(s) are filled. Remove the duct tape. The technical part is that the Turquoise is much harder and needs to be worked by hand with a small sander because when working the bowl, the turquoise will rapidly dull your tools. sanding as a unit is impossible because the wood will sand away leaving the Turquoise. It is very satisfying to see a bowl peeking out with these cracks filled with the turquoise. It does take patience.

Turquoise is readily available for much less money than you think. I purchase mine over the phone from a jewelry supply shop in
Santa Fe NM. There are many 'turquoise suppliers' available on the internet. Have questions?? [email protected]

Real turners don't turn bowls with cracks. :) Just kidding of course. As you turn more you learn more about getting wood that isn't cracked.
When you do get them most turners do fill them with some sort of dust or other material. One of the things I use most for cracks expecially larger ones, is a product called Inlace. It's not cheap but really fun to play with. It comes in different colors and some premixed stone looking colors. They also sell all sorts of fillers, such as turquoise and other stone looking things. These fillers are great to use with CA, epoxy and of course Inlace. You can get them from Woodcraft but I buy mine from www.turtlefeathers.com
The only problem with patching a crack is that you can almost never make it invisible. Consequently what is best it to highlight the crack. Most of the time if it's small I just use epoxy with a colorant. I add India ink to the epoxy.

You might want to wear a latex glove when filling in with CA glue. Don't ask me how I know.

C A Accelerator

Baking Soda is sometimes used as an accelerator for c a glue.
I have used it a few times, worked pretty good.


The model airplane guys use it to fill cracks and seams in their projects.

Google Baking soda and c a glue. A lot of info on the www.

Dano,
the other thing you can do when filling cracks with ca glue is to start out with the first coat using the thin ca like you did. It runs down in the crack and coats everything. Let it dry for a few minutes, then use the medium ca. It's a bit thicker and will fill in the gap. Let it dry or use the accelerator and you're ready to go.

I too use dust and ca glue to fill any cracks. I'll usually fill the crack with glue, and while it's still wet, I'll cram dust down in there, and repeat till it's built up. And when i'm finishing the bowl, i'll run a small bead of ca on the crack, and then sacrifice a small piece of sandpaper, in order to sand the crack and the surrounding area while the glue is still wet. This seems to really even everything out, and ensures that the crack is filled on top with the same color as the surrounding wood.

Dave

I figured it out the same way as you......
