Log Processing Center
Robert....Our Minnesota Woodturners Association club recently had a project making "LPC's" for our members to purchase at cost. We made 30 units and our members paid $30 each -- which included all the self tapping screws and complete assembly instructions. The LPC "safely holds" any size log so that the chain saw can both cut the log across the grain to length and then longitudinally, cutting the log in half. It eliminates the inefficient struggle of trying to cut the log in half down through the end grain.
Go to our Minnesota Woodturner's website at:
www.mnwoodturners.com/newsletters and find the October 2010 newsletter.
On page 8 you will see a brief article we submitted, describing our Log Processing Center. There are several pictures so you can see how it works.
It is a variation of one that Emmett Manley of Lakeland, Tennessee originally designed, built and described in the June 2010 AAW magazine. Our version has a few improvements that allow for a wider range of varying sized logs for processing bowl blanks safely. (Emmett has since advised me that he has incorporated these improved features into his LPC.)
The reason the device works so well is that when cutting the log in half, as the chain saw bar passes through the center of the log, the kerf behind the bar begins to close, keeping the chain saw from binding as it finishes the cut.
In addition, the saw drops free of the log into the gap between the vertical side boards so the saw never hits the ground or other wood as it finishes.
Our club members all love their LPC's!
If you email me your postal mailing address I will send you a set of assembly instructions for our LPC and a sketch of an optional trim shelf which allows the cut bowl blank to be positioned securely in a simple pop up cradle for trimming the blank's corners at 45 degrees with the chain saw.
Happy Trails,
