I have a quick question regarding turning an inside out Christmas ornament. I glued the initial pieces together using a paper joint like many have advised. I then put it on the lathe and I am having an issue. It is not coming apart, but the spur on the head stock is spinning and boring a hole in the head stock end. It doesn’t matter how tight I crank the tail stock, it always does it. Is there some certain thing to put into the head stock other than a spur drive? If so, what? If not, does anyone have a clue what I could be doing wrong? I’m trying to get ahead of the Christmas gift rush for family members, but this stoppage has got me frustrated and time is ticking. I’m open to any and all advice as I am a novice woodworker at best…v/r Brad

Not enough info.

What species of wood are you using?

What tool(s) are you using?

Does this only happen when you present the tool to the wood?

Are your tools sharp?

A glued block is no different than a solid one, it just has a glue line in it somewhere. It should behave just like all blanks do, and should mount the same way. If your drive spur is spinning, then you don’t have it set well enough. Getting them set, particularly in hard woods, usually means drilling a small pilot hole for the drive center, and possibly scoring an “X” across the end for the flutes to fit into easier.

Cheers,
Brad

If paper glued joint is not coming apart the paper was not thick enough to prevent all sides becoming one! My wife still bring groceries in those brown paper bags which work well for paper joints! Today cannot always get those bags so turner resort to craft thicker craft paper.

Are you installing a dead center single point drive center, 2 or 4-prong drive center in the wood & headstock?

When using my 2 prong drive center the point will penetrate the wood deeper than those prongs. Always allow for waste on each end of the ornament so can use a parting tool to part from between centers. My waste allowance little bigger if using my chuck.

So try thicker paper, make sure you your prongs on your drive center penetrate wood too.

Good luck with!

I just wrap packing tape around the ends where I am not going to be turning to hold the pieces together when doing an inside out turning. I just don’t trust paper joints on the lathe.

Have you tried just drilling a slight pilot hole to help the spur center teeth to completely engage? You can also find spur centers with spring loaded center point so you don’t need to drill a hole. If you still cannot get it to grab, Try using a rubber or wood mallet before mounting on the lathe to tap the spur center into the end grain. I assume that you have the end squared up.

Look for “steb center” ... here is a listing from Packard Woodworks: https://www.packardwoodworks.com/lathes-acc-cent-steb.html

Thanks everyone for all the great advice! I finally got it to work. I tried several of the pieces of advice and finally got it to work after cranking the hell out of the tail stock. I also ordered a steb center that is spring loaded. I still screwed it up by cutting it to deep, but at least the initial problem is fixed. Now I guess it will just take repetition and practice…v/r Brad
