Hi,

I need to cut some 20" x 17" plywood panels on a small table saw
whose fence only goes to 12". In the past I rough cut them then
trimmed with a router. That was messy - I don't have a sawdust
vacuum system. Can someone point me to a homemade jig I can add
to the saw that will allow me to cut panels of that size?

Thanks,
Gary

Maybe rough cut to one inch oversized using a skill saw. Then trim one
inch using table saw. Be careful to include width of blade.

Or

Build a table out of a large piece of ply covered with hardboard to
make it slick. Maybe use saw horses. Bolt table saw under it square to
the front edge. Raise spinning blade to bring it through the top.
Clamp a 2x4 across table as fence, squared to front at 20" from blade.

I don't know of any "jig" to drastically expand the cutting capacity of a
tabletop saw. Most folks just clamp a straight edge to the plywood and cut
with a circular saw. In fact a lot of guys who have big table saws will do
this and use the table saw to trim to size. Make sure you have a new, sharp
plywood blade on the saw.

Classic way is to clamp a straight-edged board on the bottom of your
panel such that it rides agains the edge of the saw table and guides
the cut.

Another technique is to use your circular saw. Throw some rigid foam
insulation on the floor and put the plywood on top of that, set the
circular depth of cut to cut the thickness of the plywood plus 1/8
inch. If you have enough floor space it probably the safest way to
cut.

Under the table near the edge I screwed a 2ft x 3ft peice of plywood.
Drilled & conterbored holes through the top of my 10inch cheap
benchtop.& clamp on fence.

Put your saw on the hardboard and run it down the length with the plate
guiding on the plywood. It will make a perfect cut on the extra hardboard,
which you can later line up with a line you want to cut on the panel, door,
or other piece you want to cut straight, and clamp it to the workpiece.

What you've done is almost an exact replica of the various tracksaws
on the market. Who says you can't save money if you put your mind to
it.?

What you've done is almost an exact replica of the Festool and DeWalt
track saws, including building difference lenghts of these jigs. Who

Forget the subject line and make several of
these jigs:

I have a 50" and a 96" for plywood.
