I was thinking while I made that last tool handle that I wished I had a jacobs chuck. I realized my lathe would be too short, so this way I can pre drill the hole and then turn the handle. Even then I'll still have the problem of keeping things line up correctly.
Also, I've been working on turning suspended bowls. If I keep them small enough I can just reverse them on the chuck to turn the bottom, but I've got a few too big for my chuck. I'm thinking the cone center will allow me a little more room turning the bottom between centers. I see some possible issues though, so I'll have to be careful.
