Step 15: Mistake #3: Unexpectedly Snapping Off the Lathe

I had issues with turning the wood too thin in the middle before shaping diamonds at the tailstock end. This caused the thin section to snap off the lathe.

I avoided this later on by shaping the tailstock end before going back to make the portion before as thin as I wanted. To at least savage the pieces that snapped, I sanded them down with my drill press.

To do this, I mounted a sanding wand in the chuck and used corresponding sanding pads to smooth out the jagged end. Again I used the same grits, up to 400 grit, before wiping with oil.

Since I can't do the polish and wax finish on the lathe, I just wiped on a paste wax: Tree Wax

And here is the final picture: not as long as I would've wanted, but savaged at least.

Very Good! I like the pens you filed the flats on.

Just a couple of points, first any ¼ inch rod or even the unthreaded
shank from a ¼ -20 bolt will work in place of the barrel trimmer rod. I have
even tried filing teeth on the end of the rod to make it a micro-drive spur. Adding
a little piece of blue painter’s tape will make it a jam chuck.

On your wooden jam chuck, instead of mounting on a drive
spur, just turn the end of the jam chuck to match the Morris taper in the head
of the lathe. Then the jam chuck can’t shift around.

Penn State Supply has a “Turn Between Centers Mandrel System”
that solves this problem.

I have glued projects back together after they came apart on
the lathe. Also try hardening or strengthen the wood with thin CA glue.
