Greetings All,
I mentioned in a reply to Carole's post that I had just completed a bowl from spalted birch and that I had had a heck of a time getting it firm enough to turn. Well, here is a picture of that bowl. It is about 5" in diameter, 2" deep, and has 3/16" walls.
As mentioned in the earlier post, I first tried soaking the blank in a mixture of Elmer's glue and water, which was marginally successful. After starting the turning, I got into very soft wood and tried to use CA to firm it up. Big mistake...the CA reacted with the residual PVA and started foaming, like I had sprayed the piece with accelerator. I chucked it back up and turned off the foam, then soaked the bowl in Minwax Wood Hardener. What a stench!! That did the trick though. I finished the turning and sanded to 320 grit. So far, I have one coat of Minwax Tung Oil Finish. It will get a few more coats, then a good buffing.
Sorry, no picture...I screwed up and uploaded it in another thread, then deleted it and I can't upload it a second time. I don't know how to find it after uploading.
