Machinist

I really like this guy.

Hi guys, for reference I run 2 Prototrak lathes, one 3 axis bed mill, and a few other 2 axis retrofits. My company is big into Prototrak for my semi-manual repair side of the shop. I was just wondering, with how unique the programming experience is on Prototraks, will I be able to take what ive learned to other machines? Before these I was only manual so this is really the only "CNC" experience I have so far.

Thanks in advance!

Currently trying to come up with a way to make them more than one at a time.

About an inch deep all along one side of the sheet, it split in half.

Haven't turned anything in a while. Chips!

This is a really good 3 part series on measuring the error motion of a precision spindle that I found really interesting and wanted to share.

Barfeeder again! About a minute per.

About 1:30 each on the bar feeder, 6061 Aluminum.

It's o-rings and spacers stacked and compressed, pushing the o-ring out like an expansion collet.

The pain in his face as he remakes it a fifth time.

From 1" 12L14, about 20' of stock. Barfeeders are great.

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...
