I need to make a large number of different custom screws and bolts, so I thought I'd have a go at making a big Lantern Chuck. *** WARNING - LOUD MACHINING NOISES *** Sorry I'm rubbish at using PowerDirector so the sound balance is a bit wild. Earphone users take care please.
The tool needs to handle 8mm stainless cap bolts as well as the M3 and M4 screws and bolts. I took inspiration from a video by Shelly142 in 2017 at homemadetools.net, which used a magnetic bit-holder that takes 1/4 inch screwdriver bits. Huge thanks to Shelly142 for the idea.
The other spur to action was that Emma from Emma's Spareroom Machineshop runs an annual Tool Fest, with this year's tag being #toolfest2021. Makers make a tool and share the video with a common hashtag. It's very jolly.
I was suffering from The Big Sad too much, grieving for Caroline, my wife of 34 years, who died in June 2021, so I missed the deadline of course.
Anyway, my OTHER excuse is that the Chihuahuas ate my homework. Honest...

sorry they are not complete, but there's a lot of flexibility in the design
*** IMPORTANT NOTICE - GLOVE SAFETY ISSUES ***
Please be aware that OSHA and other bodies mandate NEVER wearing gloves when using rotating machinery. I wear flimsy nitrile gloves to control raging dermatitis and because I understand and accept the small but finite risk of additional serious injury from wearing those gloves and from being careless. My shop, my rules, my life, my risk appetite. Please don't tell me I'm taking unwarranted risks. I'm taking a very carefully calculated risk between a 100% certain outcome of painful dermatitis and a near-zero likelihood but huge impact of an accident caused by wearing gloves and the rather higher, but still tiny risk of me doing something careless and the resulting injury being worse than if I had bare hands. I have no dependants and no life insurance, no employer or insurance company who needs to avoid legal or regulatory action. I see all of the anecdotal reports and a few horrific cases, and I am entirely aware of the potential impact. I do real risk mitigation and impact analysis professionally and I would genuinely be interested in statistics and research papers to help evaluate the elevated risk level I am accepting with my potentially inappropriate risk appetite. I'm not some sort of pro-glove fanatical evangelist, I just use them sometimes with cutting fluids and some metal types containing exotics or fine sharp particles.
