In the final stages of moving from the deep south to a northern state.
I used to run a shop under a corporation. Long story, but I integrated the shop, and built something beautiful. I had to use a temp service to do a lot of my hiring, I hired lots of black folks because they were undervalued and I could give them a good environment and pay. Was just starting to hire women. COVID and Qanon blew it the fuck up.
Tomorrow I'll be having lunch with two of my former crew. One of them is the only man I've ever called brother. He was my neighbor and best friend for years. I would have trusted him to help me hide a body. The other feller was a kind and gentle guy, had a bad divorce but was a teddy bear, was on the road back up.
They both went down the rabbit hole real bad.
I miss who they were and the shop we had. It was fucking jazz. I protected all of them from corporate. We made shit happen. I fought to get them more money and got fucked over myself.
I've lost my parents, my grandfather, my aunts and uncles and cousins to the insanity. Thank jeebus my grandmothers and one grandfather are dead.
Tomorrow I'm going to hug my brother and tell him goodbye. He isn't really my brother anymore. I don't trust him. I love him. He's not the man I knew.
It hurts a lot. It broke my heart.
Hey folks, pardon the rookie question. We need to build a few hundred of these per year, so I thought I'd tool up, and wanted to figure out how to do this "cheaply".
Parameters. Stainless steel rods, with one end sharpened to a point, and the other end deburred. Typically 30cm long with no real tolerance issues, and no real parameters on the point other than "if you hit it with a hammer, you should be able to drive them into the earth." Typically made of 3/8" or 1/2" stainless.
My main problem is: stainless is fucking hard and destroys my bench grinder when grinding tips onto it. Is there a better grinder I could be using? Or perhaps I should be cutting these on a small lathe?
Also, when I buy stainless stock, I usually have the metal wholesaler cut them to length for us, but they charge quite a bit. The stainless destroys my bandsaw blades, so perhaps there is a better option? Is there a mitre saw blade that is rated for stainless? Or should I also be using a parting tool on a lathe here?
Thoughts are appreciated. Such a simple thing, but stainless so...

Hey Folks, Designed and constructed in 2016-2019 as a companion project to the Antikythera mechanism, this video series is an alternative look at the second oldest geared mechanism from antiquity: The Byzantine (London) Sundial-Calendar. I designed the project as a sort of 'gateway' project into more complex horological work, especially if you're already comfortable with model engineering, and maybe feel like tackling something a little unusual. I've seen some outstanding builds of this project over the intervening years and would love to see more. So, if you'd like to build along with the series and help me make these videos, the plans for the project are available as part of the $1 tier on Patreon, find out more here: https://www.patreon.com/clickspring/about Those of you who are Patrons will notice that for this YouTube release of the series I've spruced up the intro card and soundtrack, and also combined a few episodes together to make it all a bit more efficient for the viewer. For those who are seeing this narrated build series for the first time, do please enjoy! Cheers. Chris. ________________________________________________________ A very special thank you to Patrons: Sinking Valley Woodworks Glenn Trewitt Christopher Warnock Guy Loughridge Charles Frodsham & Co.
