I've done a couple pens. It seems simple enough but the other day I realized that I have this little piece of buckey burl that is not a shape I would consider using for a bowll. I took a couple slices and cut some pen blanks.
This morning I tried one and noticed a couple things. Buckeye seems to suffer tearout. This in itself should not be a problem I just needed to stop earlier and sand the rest of the way. Then before I stopped with the chisel a big piece broke off.
So much for that attempt....I decided to experiment with ways of holding the buckeye together before I cleaned off the brass tubes and took out a piece of cherry to make the pen with.
I tried coating the buckeye with CA glue then turning it (mainly because I had the CA glue handy). It seemed to work but I'm not sure how deep it penitrates into the wood to strengthen it against tearout or breaking.
I've seen 'stabilized buckeye' for sale on the net but if you already have the wood how do you stabilize it yourself?
