It just seems like not much extra work to go full 4x8 size plus if you are cutting out of sheet goods it all going to come in at least 8x4 foot sizes and it would likely be annoying having to rip them down each time, not to mention you would be able to cut two long skinny parts at a time instead of one. I know you are decided on 2x8 but it's just a thought.I need to mill long, skinny pieces out of MDF and/or plywood (primarily patterns for boatbuilding), hence the odd size of this machine.
