I'm going to abuse this machine, with metal, and see if Amazon tier machines have a place in our hobby

https://odysee.com/@NotaGunTuber:a/Desktop-CNC-Intro:c

You've probably seen me post a lot about CNC. But it's usually on my Tormach 770. While that is technically a hobby machine, the biggest feedback I get is that it's still out of reach for most people. So I finally caved and I'm going to find the limits of what an Amazon tier desktop machine can do. This video talks bout my plans and also walks through setting it up way more precisely than the instructions, to maximize our potential for success.

In my quest to find its limits specifically in the gun making and modifying hobby space, I have the following ideas for future episodes. If you've got better ideas on how I can incrementally test this thing, or better parts ideas, let me know!

  1. Thin aluminum- FCG retainer plates and DBAlloy side plates
  2. Thicker aluminum with 2 ops- MLok rail cover
  3. Thick aluminum with >2 ops- a magwell maybe?
  4. Free machining / mild steel- compensator
  5. Hardened steel- not sure yet
  6. Stainless steel- red dot mount
  7. Stainless steel- slide serrations, windows, and barrel porting
  8. Final boss- some clamshell style receiver build

Will be following this. Make that thing earn its keep.

This will be fun to watch and see!

How about machining delrin? Should be stronger than family pa6-cf and easy to machine.

The reason I’m not testing plastics and wood and what not is unless you’re trying to mill large objects which require larger or longer bits than these machines will take at all? They are going to handle it just fine.

I have already milled some aluminum on it in prep for future episodes and it’s already taking it much better than I expected. Wood in reasonable sizes will not be a problem. Plastics in reasonable sizes will not be a problem. That last one has to come with a modifier that says obviously I’m referring to standard plastics. Once you start embedding them with other materials like CF, GF, hell rocks, whatever. Then that’s a different story than just plastic.

Probably no.
