Back to the drawing board

The club challenge for October in inside-out. I had an idea to incorporate my multi axis turning on the inside face. So I chucked up a piece of Home Depot redwood and turned a prototype.















I had to leave the ends square so I had some area to glue once its turned inside out. Normally I would turn all the way to the ends of the blank. Because this is only a prototype I didn't do the preliminary glue up.














Instead i turned it as a solid piece and then quartered it on my band saw before turning the sections inside out. The results weren't what I had in mind so it went in the recycling bin and I went back to the drawing board.














My second idea was more successful and closer to what I had in mind as my concept. I started by gluing 4 pieces together with a paper joint and turning a wide cove.











The paper glue joints were the split apart and the 4 pieces turned inside out and glued together permanently. I opted to turn on 4 axes with a 90 degree twist to match the 4 diamond shaped openings formed by the inside-out process.









It's not perfect but it proves the concept. The glue joints could be much better; that's one of the reasons I'm not a segmented turner. I'm also not sure how this concept could be incorporated into a finished piece. For now I'm just happy that I was able to get my proof of concept done.

Proof of concept

I've had this idea kicking around in my head for a while, a different take on a hollow form.  Donut shaped and hollowed from the inside edge.

 I'm still refining my approach, but I think it has promise.  This is my first attempt and the piece was secured to the wooden jam chuck with hot melt glue.  In order to hollow it out I will need to flip it over, the last time I flipped this sample I didn't use enough glue and it was torn free from the jam chuck.  I either need to rethink my approach or use more glue (or both).

As it sits it's only partially hollowed, about 1/4 to 1/3 done, but it will remain as is for at least a week.  I'm headed to California for work all next week.  I fly out first thing Monday morning and return late Friday night. Longest I've been away from home in close to 3 years.
