Machining
This 8-minute video uses a simple project to demonstrate basic metal working skills and tools. It probably tries to teach too much in too short a time but we think it’s still a good video. You’ll learn how to accurately layout and drill holes, the proper way to use hacksaws and files, a variety ways to use digital calipers, how to safely use a drill press and and much more. Unfortunately it doesn’t mention center drills. <p style="text-align:right;color:#A8A8A8"></p>

Grinding Lathe Tools on a Belt Sander – For the New Guy | MachinistBlog.com
I’m a believer . As a new guy I totally sucked at grinding lathe tools. It’s almost painful to admit how many stubby, misshapen, multi-faceted, overheated and just plain ugly lathe tools I made back then.
First complete job … completed I finished a little Air-app to stream complete jobs to the Grbl and render the result. This is the first “full scale test” running some 7000 lines of sample G-code I scrounged from this thread on CncForum . The Air-app feeds g-code to the microcontroller one line at a time, while the microcontroller generates the steps and feeds them back to be simulated in the Air-app.

CNC Router Build – The Stand | MachinistBlog.com
The stand for my Solsylva 25x25-inch CNC router is made from 1x4-inch pine boards. Two of the supports are hinged so you can fold the router down so it takes up less storage space. Building the stand for my Solsylva 25×25 CNC router was pretty simple. The hardest part was attaching the hinged support. I also had some trouble finding straight lumber for it and the rest of the router.
