Put the pin into the Arbor Plate hole and push it all the way down. Dab the JB Weld onto the pivot pin in the scratched up areas. Mix up a small dab of the JB Weld, a pea-sized amount is plenty. Clean the pin with alcohol or naphtha to remove any oil. If it’s loose, I grind around the circumference a bit within ¼” of the rougher end. If it’s tight, I grind the rougher tip (end) of the pivot pin just a bit to give the JB weld something to hold on to. Depending on your drill bit, your Pivot Pin may be very tight, or a little loose. It’s much stronger with ¼ or so of the plate depth intact and Cast iron, when used in this type of application, can easily crack if that hole goes all the way through. We want the top surface of the arbor plate to remain unbroken for looks and for strength. ![]() Don’t drill all the way through the arbor plate, just go to the same depth as the roll pin hole, maybe a 1/16th or two more. There is a 5/16” solid steel pivot pin in your kit. Also, drill out the hole in the arbor plate that the roll pin came out of, again 5/16”. The whole press sits nice and flat on my drill press table upside down. Turn the whole press upside down and drill out the arbor plate pivot hole with a 5/16” drill bit. Then, using a big screwdriver or pry bar, just pry upward on the arbor plate, leaving the pin still clamped in the vise.Ĥ. I’ve found the easiest way to remove the roll pin is to clamp the pin in a bench vise with the split pointing out sideways. ![]() The tolerances of the arbor plate pivot are sloppy. Remove the roll pin from the round arbor plate. I made mine out of 5/16” round steel one inch long, but you can buy them at McMaster-Carr. I’ve had them with globs of stuff stuck to the bottom that kept them from sitting flat on the bench.Īt this point you have 2 choices: You can keep the loose-fitting roll pin that serves as a pivot or replace it with a solid steel dowel. Also, check for crud stuck to the bottom. Scrape off the mill shavings, casting slag, mold sand, and whatever other crud is stuck to it. ![]() You also need four m6x1mm nuts.Ģ.Ĝlean it well. If you want to replace your fasteners you will need six M6x1mm 25mm long and two M6x1mm 30mm long. I don’t use the adjustment shoe so I just toss them into the scrap bin. I replace them with new, quality bolts and nuts. Take it all apart, I always throw out those ratty black bolts. These were available from Harbor Freight but they seem to have been dropped from their lineup. Here are the instructions along with some suggested parts sources.įirst, buy a ½ or 1 ton Arbor Press. I have been getting requests for rivet presses, press kits and guidance since we closed PinRestore in 2021.
