Step 1 is pulling the motor from the drillpress, though to be honest I probably could have installed the new plate without unwiring it completely. Here’s an example of how the setup will actually affect my spindle speeds using the slowest pulley combinations: The idea of being able to drop these speeds in a cost-effective way was very tempting. as we all know, REAL metalworking drill presses are a LOT more money than the woodworking ones (I think I paid maybe $300 for this one brand new). This is a woodworking drill press, so the spindle speeds are substantially higher than what you really want for metalworking…. Here is the original speed chart for my Delta. It consists of a large offset pulley mounting plate, and a set of 4:1 ratio pulleys that will cut the speed of the motor down to a fraction of it’s previous setting (about 25% of original, I’d say!). Here’s the holes I am trying to drill, and the kit that I received: (Diet Coke not included) He suggested a 4:1 reduction kit based on my particular drillpress (Delta, Model 17-965) and a few days ago the kit arrived via UPS…… it gave me some motivation to get back into the shop and start spinning a few wrenches. Fortunately, Joe over at RogueFab saw my previous thread posts and contacted me about my drillpress issues, and we talked for a while about his reduction kits and how they would be a low-cost way to give me better cutting capabilities, and finish up all of those 2″ speedholes in the monolith crossmember. probably weather-related, time change….whatever. It’s been a rough few weeks and I haven’t been making any efforts to get out into the garage to work on the truck project. The belt size of the kit doesn’t need to match your drill press at all.Ĭlick here (new tab) for Drill Press Reduction Kit tech (way more info)! Also, it is very important that the shaft size of the kit you order matches your drill press motor. If want your drill press to go slower and have more torque, this is the kit you should order.The 4:1 is our most popular kit, and the one we almost always recommend. This kit uses cold rolled steel shafting, high quality cast-iron block mounted greasable ball bearings, and ships raw (the main plate is not painted).
