Retracting Key Ring Corrals Chuck Key. Noticed this write-in tip from Matthew Hakeman in the most recent issue of The Family Handyman.
Googling discovered the title image in a thread over at GarageJournal.com, from user evintho. Looks like he’s put a metal strap around the key between the handle and the teeth. The illustration to right is from WoodworkingTips.com, and shows an alternate method for attaching the key ring to the chuck key using a short wooden dowel. I like this tip a lot, and I happened to have one of those retracting spring-reel key rings lying around, so I tried it on my own small drill press, as shown in the picture below.
How-To: Center Stock in a 4-Jaw Lathe Chuck. Tools, Parts, Kits for DIY'ers - Curious Inventor. Basic Metal Working « MachinistVideos.com. 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.

Grbl development log. 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. The stand for my Solsylva 25x25-inch CNC router is made from 1x4-inch pine boards.
