well, i ordered a drill press from harbor freight. nothing fancy, nothing special, really cheap. the reviews were decent and the video shows it seems to work well. it isnt a big one but i dont need anything huge or fancy for the things i will use it for. https://www.harborfreight.com/8-in-5-speed-bench-drill-press-60238.html?_br_psugg_q=drill+pressshould have it in a week. works out just about right timewise with the parts coming.

That drill press was only $50 something when they went on sale a month or 2 ago (?).
You want to see a cheap drill press how about this. Got it at a yard sale for $10 on half price day and as you say "miles ahead of a hand drill" for some jobs. I keep it in the garage so I don't have to go to the shop every time I need to drill. It's even a variable speed model cheaply made but strong and accurate.
Aluminum has it's place in a gun but not the best choice for a valve.Arguably, one of the best low cost upgrades for a 13xx might be a brass valve.They show up on eBay regularly for around $10.Some are 70 years old and look like new after a little cleanup. Stripped screws and migrating valves are a thing of the past.
Got mine pinned using Gary's diy. The valve gets chewed after a while even if i keep the trigger screw tight and decided to add an opposing set screw as per Wyoman. Stayed in place ever since.
Robert, you'll probably need to finish with a bottom tap or grind a bit off the (1/4" long) screw, or both. Otherwise the screw may not go deep enough to sit flush with the tube.You can make a bottom tap by grinding the tip and chamfer off a regular tap.Keep in mind that you're using a small tap, in a blind hole, with 100% thread, in metal... use caution - reverse the tap often to break the chips, use some light oil for cutting fluid and have your compressed air ready to blow out the chips... hth-Wyo

You need to start the threads with a "plug" tap (a "tapered" tap has too much taper for such a shallow hole).... and then finish them with a "bottoming" tap.... You can grind almost all of the taper off to make a pseudo bottoming tap.... Look at some pics of them online to get the idea.... They are often sold in sets of three, one of each type.... Do not try and start the threads with a bottoming tap, you will almost certainly get them started crooked, or just strip the hole.... Bob
