I am selling a set of 2 brand new riser blocks for the Powermatic 3520C lathe. They will give you an additional 4" of height for your lathe. I took one of them out of the box for the photos here, but otherwise these have been in the manufacturer's boxes since the lathe was received over a year ago. These are made for the Powermatic 3520C lathe, so check compatibility with other models if interested. Located in the Philadelphia, PA area. Price is $120 for the set, not including shipping.
