80% help needed

[OneShot]

Destroyed my drill press milling an 80% lower. I was using the Harbor Freight milling vice with a Delta drill press. As soon as I realized the piece was not secure it was ejected from the vice. Resulted in bent spindle and shattered variable speed pulley in the drill press. Parts are no longer available for this discontinued model.

Would someone with the tools and experience be willing to help me complete this project? Preferably near W/S or Greensboro...

Drill presses make horrible milling machines. They usually use a morse taper to secure the chuck to the spindle but its just a pressure fit and not secured with a draw bar. When you side load the chuck it creates unequal force on the taper and loosens it from the spindle. If you must use a drill press for milling, you should drill out as much as possible. Then you take extremely light cuts with the milling cutter.

Try searching ebay for the parts you need to repair your drill press.

how much did you pay for that drill press?

you could have bought the proper 80 jig and avoided destroying your drill press for the same price. they don’t take lateral loads very well. even if your lower was properly secured.

you’re gonna be hard pressed to find someone to loan you their jig. might be just as hard to have someone help you cause then you start getting in to the weird area of manufacturing a firearm.

best bet, but the jig kit and use it a few times and sell it.

When a friend wanted to do some 80%’s, I did a little research and quickly found that drill press jigs are less than ideal. Using a compact router yields MUCH better results. The first one came out really good, only a couple minor imperfections, and the subsequent lowers came out nearly perfect.

How did you set it up?

We just put it in a bench vice. The jig helps you make sure the lower is positioned perfectly and is easy to use. The jig was very similar to this but I think it was the red brand (can’t remember the name).

I've used my 40 year old Black and Decker cheap-o router and some patience with good success.

Before I purchase any new stuff, would anyone be interested in showing me their set up. I would need some instruction and do all the milling myself. I would bring beverages for you and snacks for your firearms (as long as it's a normal diet, like .380, 9, .45acp or colt, 7.62x39 or 51, or .223, or green tips).

Preferably within an hour drive from Winston-Salem.

To avoid a flood a gay porn, I'm not posting my phone number. PM if you can help me out.
