Thanks to all who participate in these useful and entertaining forums.
Here is my new project for your consideration.

I am planning to build a large X-shaped sawbuck for the purpose of
cutting firewood on my property. I am still in the pre-planning stage
but have a few ideas I am ready to share. I want to be able to
gang-cut multiple logs or slabs in this device. I want to be able to
load it either by hand or with a Bobcat grapple. I also want to be
able to pick it up and move it around with a Bobcat forklift. I want
the uprights to be spaced so that I can cut a given length of wood by
cutting at the location of the uprights .

As to the materials and methods. I have 4/4 rough sawn oak on hand but
am willing to consider something else. I have my own sawmill and can
mill oak or poplar to any dimension. I could also buy treated. I
think I can make the uprights by using a lapped joint. Each upright
could be a sandwich created by using one full lenght 4/4 board and one
board cut to create the joint. I could also mill or buy some 8/4
stock and then just notch the uprights to form the joint. What do you
think? What thickness and width of boards should I use for the
uprights?

I have scrap plywood on hand that can be used to brace the lower half
of the uprights and also between the lower uprights. I then plan to
use 1x4's or similar as braces between the upper uprights. This will
allow me to access the sawbuck from the sides or the ends for the
purpose of moving it with the fork lift. I am planning to pick it up
from the sides by putting the fork under this bracing and from the ends
by puttng the fork under the X itself. Screws and liquid nails are
what I have in mind for fastening. How does it sound so far?

I think it should be 8 feet long which is the length of logs I am
cutting. What should the overall height of it be? At what height
should I make the X where the uprights cross? It should be short
enough to be hand loaded and easily used but it should be tall enough
so that it will hold a generous amount of wood. I am six feet tall.
What should the width of the base be? It should be stable on uneven
ground. I am planning to do a drawing to finalize the details.

Please let me know how these ideas sound to you and if you have any
questions. Please also offer any ideas or sugeestions you may have. I
plan to scan and post the drawing for the group after I get some
feedback but before I finalize the details. I also plan to post pics
of the sawbuck. Thanks again to all for your participation.
