Mike,

Are you asking about splitting a long in half, making two half-rounds? 

or

Are you asking about once you have a half-round, cutting the corners off so that rough turning is quicker?

In case 1, I use a Shopmate table and make my cut 3/4 the way thru first then stop, rotate the log, and complete the cut.  I have the shopmate top open about 4-6 inches so the log will not roll.

In case 2, I use a bandsaw, but if I wanted to nick the corners with a chainsaw I guess I would use a rachet strap to hold the half-round in place on the shopmate table, hanging over the corner to be cut.  But honestly, that sounds like more work and time than just putting the thing on the lathe and going at it with a roughing gouge.

Most of all - Be careful.  No piece of wood is worth getting hurt  Sad .

I posted my cutting stand before but it really works well. Keeps my back and works great for trimming half logs as well as whole round sections

This is what I do to hold them to trim the corners off. Very quick and holds super well.
A $12 bench holdfast works just a well, I already had a fancy one.

Generally, I will put the log blank up on another log stood up end grain wise, and chock a couple of cut offs on either side to keep it from rolling. I use a level to mark a plumb line through the center, or to either side, and have a number of plywood strips in various widths to mark off how thick of a blank I want (no measuring). If I am going to cut off the corners, I make sure to cut off the bottom outside part of the bowl blank before cutting down the center. Mostly this gives a flat spot on the bottom of the blank for it to sit on so you can mark a circle, and then trim off the corners. With the flat spot, it will not rock and roll when trimming. When trimming the corners, start cutting on the left side, so the teeth on the side of your chainsaw can dig into the log and hold it still. If you cut going to the right side, the log will want to spin into the saw. If you have a really big piece, and are going to cut several blanks out of each side of the pith, cut about 90% or the way through, then roll it half way around and cut the rest of the way through.

Thanks Ron, I got the basic idea from someone and improved the design to be stronger and fit my needs. It is very functional, you can trim the edges from the 1/2 rounds while on the frame that is on the ground. Or you can trim them from the half-round holder to the left of the stand. My stand doesn't look anything like the picture anymore (much more worn) because I have used it to cut so many trees up. But still very functional for pieces that you can actually pick up and put on the stand. Splitting the extremely large rounds(those you can't pick up) you must do on the ground.
