Ok all you Guru's of Pen Turning, what am I doing wrong?
I cut the blank I am using to size, drill the right size hole in it and then use CA and glue the tube in .
Then I put them on the mandel and tighten it properly. start turning and I get it down almost to size, and one of the pieces will split.
I not using excessive force when I turn them or taking big cuts. Help, getting tired of throwing away 3 bucks worth of Wood (I am usinig Plnk Ivory,And I have used it all up now)

Are you trimming the blanks after gluing the tubes?

Are they separating from the tubes when they split?

How thin is the wood when it splits?

Are you having this same trouble with other woods?

Yes Doug I square the ends. It is like about a quarter of the tube of wood splits off. the part that splits comes unglued I guess.
And Yes it has happened before with different types of wood? I don't understand it my tools are sharpened proir to start turning??

I've always had good luck with CA, but you might give epoxy a shot and see how well it works. The other thing is to leave the wood just a little thicker and of course, take light cuts near the end.

Is the CA glue the medium stuff? Are you scuffing up the tubes on a piece of sandpaper before gluing them in? Richard I'll be around Sat. night if you want to come over, just give me a call.

OK guys, We, that is Dave and I, discovered that I wasn't scuffing up the tube. Causing the glue not to stick on part of a tube, letting that part of the wooden tube to move allowing it to split.
Oh well, you live and learn.
