The question above is asked a lot and I can understand why – drill presses can make accurate holes. Surprisingly though – DO NOT USE A DRILL PRESS WITH YOUR POLYMER80 JIG! How’s that for an emphatic answer – now let me explain why this is so.
The cool jig that Polymer80 came up with is designed to be clamped from the bottom and three holes on each side to be hand drilled. All of the stresses and what not on the jig were planned so the holes would go in the right place. Laying the jig on its side to use a drill press has led to alignment problems and frames that don’t work so don’t use a drill press.
While we are talking about drilling – do a hole at a time and do NOT drill straight through. The reason you do a hole at a time is that you can afford the angle to be slightly wrong on one side but if you go straight through and the angle isn’t perfectly true then the hole on the other side will be way off. Trust me, do a hole at a time. Yes, do take your time and try to drill a hole that is perpendicular to the frame – meaning not at an angle one way or another off the center of where you need the hole.
Use 3 & 4mm Drill Bits
The frame needs 3 and 4mm drill bits and the jig is labeled for what size goes in what hole. If you need the bits, we sell nice drill bits that are perfect for this. Click here to go to our Polymer80 tool page.
So, you don’t need a drill press but I would recommend a vise to hold it vertically nice and steady. You can get pretty good deal on little 3-4″ removable vises that will work just fine or you can use any woodworking or metalworking vise if you already have one.
No, you don’t need a drill press and for that matter you should not use a drill press because the jig was not designed for it. However, you do need at least a 3-4″ vise, hand drill and the right size bits to do a good job drilling. From there, you still need to trim your top tabs, remove the barrel block, clean things up and then you can install the parts of your choice.
