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...

The company didn't pay the mortgage for over a year, and our nearly new lathe got very rusty.

Pretty nifty. Using several clamps, I could see this working just fine for short run aluminum jobs.

You can really see the difference few inches in

If it's stupid but it works it ain't stupid

So for the last month-ish Ive been working at my new job as an injection mold operator, which has been rather interesting. I first thought of injection molding as a basic concept of hot plastic gets shot into a mold and gets ejected. But there is so much more that goes into injection molding. There is back-pressure 5 heating zones a TCU which helps the plastic cool in the mold before it is ejected. Then the eject pins extension length and speed. There is probably a lot more as-well but that's just to name a few. There is so many variables into running a injection molding machine, luckily the company i currently work for is teaching me everything and im trying to learn as much as i can (which is slightly overwhelming).The only real annoyance is the plastic smells quite a bit and i read all the MSDS's i can. Something i learned that was a neat tidbit is that plastics like Acetal and TPV, and many other co-polymers is they have alot of nasty stuff in them, and the nasty stuff is only released if it gets above the recommended plastic temperature which is rather important to keep it with a safe range.

On a side note the last place i worked, i liked the people but hated the job and lots of people said the equivalent of "same shit different pot" aka the job you had is going to be alot of the same even if you move. And there mostly right, instead of carbide and kobalt its plastic. The only big diffrence is this place is full time and actually doesn't bully you for wearing PPE, as-well the people there are also rather nice just like the old place.

also any other injection molding operators in the community, and if so do you like the job? as-well as any experiences with it.

also huge thanks to everybody in the thread for helping out and getting me to this point!

its an enco and i cant find much info on it is most likely not more than 2 horse. i dont plan to do any crazy pocketing and REALLY WANT A MILL to match the sexy tractor lathe and use it for hobby projects.

whada u think machinists? i cant imagine it going for more than $500 as its not a knee mill
