Panel Saw Construction Project ---- Enhance Safety of Shop Operations.
Submitted by Ed Buell
One of the things I’ve noticed as I spend time with the
WOODCRAFTERS in the Mustang Shop was that Herm Finkbeiner always seemed
particularly concerned whenever we were breaking down whole sheets of
plywood. On our big DELTA saw, even with
the large table extension, this is a marginally safe operation. We spend a lot of time talking in the shop
about what things we do that are, either unsafe or at best concerning to our
welfare.
A couple months ago I suggested during a Saturday
WOODCRAFTERS meeting that we consider getting a panel saw for the shop. This would alleviate the safety concerns and
make that work much easier. After some
discussion, I sought out panels saws to procure or build. I prefer to build stuff for the shop in the
shop. That’s the best way I have to
learn about how to get projects in the shop and at home completed.
Commercially available panel saws are very expensive. Those that could cut plywood both into 4 X 4
and 2 X 8 pieces were very long as the support has to hold the pieces up to 8
feet from the saw location soothe piece can be slid through the saw. In my researching, I found a set of plans in
WOODSMITH SHOPNOTES issue 88 that had a traversing saw carrier, that would cut
both sideways and up and down, and the whole thing is only 10’ long.
After discussing this with several WOODCRAFTERS, we decided
to go ahead with a PANEL SAW building project.
Charlie Goddard signed on to co-chair this project with me.
The one big problem we faced was where to put it. The design is intended to be permanently
mounted against a wall. Well,,, we don’t have much empty wall space. We thought about putting it on the outside of
the sheet good storage bin, but it is not square and wasn’t made to support
anything else. So, we are making the saw
basically to plan and then we are going to design and produce a portable base,
so we can move it around for storage and use.
I also found a modification another woodworker made to
extend the height of the saw by one foot in height so that it would handle the
5 X 5 sheets of “appleply”… so we have
modified our plans accordingly.
Charlie sourced materials from our stash in the barn and
milled materials for the main frame. The
original plan was made with 2X2 material.
We’re fortunate to have good stable Ash and mahogany for our
project. We’ve been working the project
for a couple weeks and on Tuesday, May8, with Wayne Distin’s help we assembled
the main frame. I the pictures below the
frame is actually upside down. Our next
task will be to begin to manufacture the carriage and carrier for the saw. We will follow on other articles as the
project proceeds.
You're right about the danger involved in ripping 4 x 8 plywood sheets, especially with a circular saw. I once had a summer construction job and saw (pardon the pun) a serious accident: a carpenter had leaned a full plywood sheet against an object in a corridor and was ripping it with a circular saw when someone tried to squeeze by behind the sheet. The blade must have been set deeper than necessary, because it ripped the person's leg. Messy!

In our shop the problem is heightened because we have many people who come to work on our projects or for classes and we don't always know what their experience level is and whether they understand the risks associated with the work.
