Cutting a cylinder lenthwise
I have spindle- turned four 2.5″ diameter cylinders 36″ long. I want to cut each cylinder lengthwise into four pieces. Thoughts on how to make the lengthwise cuts?

billy,
if the workpiece had been 4 parts glued together with paper between the glue joints, you'd be home free. the cylinder needs to be attached to a flat board that can ride along the fence of a bandsaw for cut #1. cut #2 will need to be made with the 1/2 cylinder attached to the same flat board that now has a piece fastened perpendicular to the bottom edge of it.

If you have a BS
As someone else mentioned you could glue up the quarters and redo on the lathe and seperate. You could make a sacrificial sled with a 90 v notch cut in and then run it through the bandsaw with the caul against your fence. First cut it in half and use double stick tape to put the cylender halves back together (or the caul) it back together and run it through again and bam done. I used an example of a 2x4 but you could use anything that's strait with a v notch in the center. I did a mock up in sketch up to better explain.
That's a nice simple solution Bones. I would have done something much more complicated, and have.
One suggestion: I would add a 3" square piece of 1/4" plywood to the end and put two small screws in each half of the cylinder and each half of the sled to keep everything from shifting while cutting, being careful not to place the screws in the cut line.
Thanks, Bret
