Topic tags/keywords: spring pole lathe split spinle question

My next Prie Dieu will feature a a split spindle. I’m aware of the brown paper glue-up to achieve this, but I’m concerned about stressing the glue joint with my spring pole lathe. I do not have mandrels, just metal centers from a weaving shuttle.
 

 
I’ve considered driving cut nails from opposite directions at the ends of the turning blank, or even a leather strap of sorts to keep the blank from flying apart. What say ye? Any experience with a split spindle on a spring pole lathe?

Thanks in advance for any and all comments.

run the blank long and short sheet the paper. cut the end back to length when done then split. I dont run a spring pole and use cup centers typically though.

I think I saw someone wrapping a few turns of packing tape around an inside out turned ornament. If I remember right they skipped the glue altogether and just relied on the packing tape. That was very small scale though. I bet between the glue and the tape you’d be fine. But I’ve never done it so it’s purely conjecture.

Why not do a test before completely dismissing the idea

Thanks, guys! I like the packing tape approach. This would hold as well as the cut nails, I guess. I do, however, think I’ll need to do the glue-up. The spring pole lathe only allows cuts on the down stroke and offers not a lot of torque. A misplaced tool has caused this thing to stop dead in its tracks or even dislodge the work-piece, sending it crashing into the wall. Without the glue I’m afraid the blank might crack or at least have a chunk of wood go missing. Guess I’ll glue things up with brown paper, bind the “extended” ends, say a little prayer, and see what happens. Thanks, again!

You might also want to consider using automotive hose clamps.

Thanks, Rufus … I’ll look into that as well!

UPDATE … Turning a split spindle on the spring pole lathe was rather uneventful and required no special preparation. I simply glued the two halves together with brown craft paper in between. I did do as REO suggested and ”short sheet”  the paper about 1/2” from either end. This proved sufficient in keeping the blank from splitting on the lathe. Check out my blog to see the results.
