I’ve been using the Northwest Short Line “The Dupli-cutter for years.
It is a great product for cutting styrene.
Now that I’m making things for large scale I needed something heavy duty.
I need a dupli-cutter on steroids!
Found some parts at Tractor Supply (½ X ½ X 12”), and the rest at OSH.
The plywood base is from piece of scrap.
The brass threaded rod is 10-32, as well as the brass nuts, and washers.
The knobs are 10-32. The clamp is from a block of delrin that I’ve had since the 80’s.
The T-Slot usually takes ¼ - 20 bolts, but I made some sliders out of 1/8 X 1/2 flat stock drilled and tapped for 10-32.
With the T-Slots I just slide the clamps wherever I need them.
With the dupli-cutter I would have to unscrew the clamp and screw it in the other set of holes for longer pieces of styrene or PVC.
