Polymer Paperweight

Has anyone finished a JMT 80%?

Thinking of doing one of these in the future if the fair wind blow in my favor, and wanted to know if anyone has had luck doing them using just a drill press?

Absolutely. i did my poly80 lower with a dremel. the press will make it easier and faster. watch some videos and take your time. good luck

What mnichols said X2. Take your time. The videos that have been created don't show a bit or end mill "chattering". Make sure you have a good vise and have it securely anchored to the drill press table. Check, double check, then triple check before you drill or mill anything. a messed up lower and a pregnant woman have this in common - you can't unscrew either of them.

If you screw up the trigger or hammer pin holes, like someone I know did, KNS anti-walk pins are your friend. You can hog out the holes a little and the KNS "dog bones" will retain the pins much closer the correct position.

Hope this helps.
