I just set up my new shop, dust collector, air filter, assembly table, table saw at the heart of it. I even did a kitchen cabinet fab job already. A friend wants to make some cuts for a project of his own. “Of course you can.” Turns out I am not set up to cut big pieces of plywood. He needed something like 82×22. How do you accuratley cut 82″ length (or about)? I love jigs. I like a big work table. That does not change the fact that my rip fence only goes out 52″. I don’t want to gauge against the waste end of my material. Short of a panel saw, what do I need?

The easiest and cheapest way is to make a jig out of plywood and your circular saw to the length that you need. Rip a 3" long piece nice and straight, and attach it to your jig piece. Running the circ. saw with fence along the newly cut piece, you'll cut your jig to exactly the distance from the blade to the edge of the fence. Align this newly cut jig on the line you wish to cut on the plywood sheet. Make sure you cut with the good side down, as tear out will be minimalized on bottom side.
Many tool companies also make these jigs ready made out of aluminum, or you can get a plunge saw from festool for some more $$$.

To net a 82" cut from a 96" panel set your fence to 14" to the outside of the blade and with some form of support simply crosscut it . A sled will also work .If you don't want to use the factory edge then rout a 1/16th or so off first .
good luck dusty
This is the way I have done it in the past, that is, cut the smaller end to the right size to leave me with the larger piece at its correct size. I just don't like gauging from the waste end of the board. Maybe I should just get over it and get used to it. Thanks
allisgood,
I have done it the two different ways already suggested. The issue becomes support for stock extending beyond the crosscut sled. I've never done it, but there is an idea out there for building a left side support using the end of your fence rail. Basically, you fit a piece of stock in the end of the rail(in front, make it adjustable)and tenon that into a vertical piece that goes to the ground. On top of the vertical piece is attached another piece of wood that runs parallel with the TS and has a 'T' base on the other end. (hope this it not too confusing). The nice part is it can be taken apart and stored while not needed...
I like the sound of this. I may spend some time today working on this one, thanks.
Add this smart base and you have a "system"

I cut 1/4" ply with no chips and with a framing blade.
You can use the smart base without the ez smart system.
good luck

I have both the guide and the smart table - works great. I know Dino would give me grief but for most stuff I cut 1/4" greater than I need and finish on the TS (really helps to make sure my pieces square up). Of course you wouldn't do that on the TS with 88". Of course the smart table works with a shopmade jig as described above as well.RogerI'd rather be making cabinets and friends....

cut it a little over length with a circular saw and clamp a straight edge across and make the finish cut with your router, that is the way I have done it many times
It sounds like you didn't put your assembly table behind the TS. If they're both the same height, you could move the assembly table so it could act as an outfeed table. I use saw horses on the infeed and outfeed sides to cut it to width. They work great and I rarely need to cut the piece oversize and recut to clean up the edge. For the end cut on a piece this long and narrow, I would clamp a guide across it and cut with a circular saw or jig saw, then clean it up with a router and straight bit (no spiral up or downcut here- it would chip the edge on one surface).
