Lantern Chuck

I needed to modify a lot of 5mm to 8mm stainless bolts, cutting them to specific lengths with a domed and polished end. I was inspired by the lantern chuck posted a few years ago by Shelly142 which included a hex socket to hold driver bits to hold screws and bolts firmly against rotation. I dug out some bar ends form my metal store and made myself a lantern chuck, using a black-finished hex driver socket with a magnet and clamp ring. Rather than pressing it in as Shelly142 did, I milled a groove in the side of the hex holder and locked it against rotation using a dog-point setscrew. To give me a bit of flexibility, I used a setscrew in a threaded bore behind the holder, and machined another setscrew with a cylindrical point to fit inside the socket of the first one to lock it in place without it turning.
I posted the video on YT a couple of weeks ago, but the audio mix was terrible so the link below is to the new, updated version with much less machining noise.
Huge thanks to Shelly142 for the inspiration.
