My table saw has capacity on the table to cut the ply panel but the fence rail does no have the capacity to lock the fence.

Has any one clamped a straight edge to the tabe saw extension wing and used it as a rip fence? Would this be safe?
I would use my track saw but it would be difficult to set it up and keep the kerf in the 1/4 inch waste.

Thoughts opinions...... would you do it?

Thanks
