This will hopefully be of interest to some folks.
As some of you know, yari poles often come cut here in the US, due primarily to shipping costs and storage issues (see pic 1). I wanted to display the pole as a single piece, however not by doing a permanent, blended repair (may come later). I also didn't want the fix to look completely out of place (e.g., clamps, duct tape, etc.).
I decided on a quick collar that resembled a kaburamaki to somewhat blend in with what would normally be on a pole (I know - its position is too low but that's where the cut was). See pics 2 and 3. This attaches without glue or fasteners so the pole can be disassembled for storage or shipping.
Here was the process for those interested in doing a similar fix:
1. get a pole of larger diameter. In my case, a wooden curtain rod worked.
2. cut to length and drill out the center. I used a 1 inch forstner bit.
3. Sand to a barrel shape to represent the kaburamaki
4.Wrap with cord. In this case, I used yellow hemp cord that I dyed black.
5. Slip over the ends without glue or fasteners. It will hold for display and allow the pole to be quickly taken apart and shipped/stored.
