FILENAMES: Punch-Notch_cart_1.jpg Punch-Notch_cart_2.jpg Punch-Notch_cart_3.jpg DESCRIPTION: These are pictures of a cart for a punch and notcher. Posted by Ernie Leimkuhler . The following description was provided: ================================================================= These are pictures of the cart I built for my Roper-Whitney HP520 Hydraulic punch and Diacro#1 Corner notcher. The cart is designed so the die height and notcher platten are at 34" from the floor which matches all of my work tables. This means I can lay a full 4' x 8' of sheet metal on a table and simply move the cart around the sides to notch corners or punch holes. The punch is a 20-ton punch capable of a 1/2" hole in 1/2" steel, or larger holes in thinner metal. The Punch came from Boeing Surplus. The Notcher I got from eBay.
