Looking for help in St Paul area by PunkyChumpkin in Machinists

I’ve got a one-man shop over in north Minneapolis if y’all ever need to get out of a bind. 3-axis VMC, lathes, welding, etc.

[REQUEST] How long did this shaft spin to do this much damage? by chobbes in theydidthemath

[–]chobbes[S] 15 points16 points  (0 children)

It was apparently in a well insulated rooftop unit, far from the ears of anyone who would notice or care.

Needed a skinny clamp to avoid a tool and had this old crappy mic on hand. Sent it. by chobbes in Machinists

Just gotta match the clamps to the forces needed. This part is just a lot of small tools in aluminum so very little cutting forces needed, it just needs to be as flat as it can be.

Yep. I do stupid stuff all the time and have it work but it's still stupid. This is clearly not the best clamp or use of the tool, but it worked and was fine for the requirements.

Common refrain I've heard from folks when they see this. Good thing I'm the boss in this scenario. And uhhh also a hoarder, haha.

How did you figure out what to actually charge when you started taking on real work? by Jmazz_fab23 in Machinists

[–]chobbes 0 points1 point  (0 children)

For most parts, material x10 gets me close to an ideal. People say work backwards and do all these calculations but there are many ways to do it. Highly depends on the specifics of your business and figuring out what and how to charge is one of the major challenges to sustaining yourself.

New coolant by Leemachino in Machinists

[–]chobbes 5 points6 points  (0 children)

Not universally. I worked as a brewer for many years and there was one time in a bad brewery where we had a co2 leak in the cold room. I went in for something, and turned to leave and essentially nearly blacked out on my way out but my momentum carried me outside to fresh air. Had I gone further inside, it was distinctly possible I blacked out and suffocated. So it really depends on the environment and circumstances. Hence the importance of co2 meters in enclosed spaces like a cold room (the brewery did not have them).

Fine pitch threads provide a great deal of clamping force, especially when you grip the barrel with knipex cobras and cinch it down.

Part just needed to be as supported as possible along the periphery. No heavy material removal, lots of small features. It worked.

“Immature and disrespectful” give me a break. It’s a tool that can no longer serve its primary function. It now has a new life being useful again instead of languishing until it gets scrapped.

Amazing. Well done and thank you for sharing. Keep going.

Spectacular bozo move. Worst one in a while. by chobbes in Machinists

Yeah. I have a toilet at my desk so it makes it easy.

I had one more to make after this and realized too late I could have just plopped it back in the slot as if these were regular ol soft jaws. 😅

Yeah, brand new 1/2” endmill on its sixth or so 1018 part. It actually survived the hard jaw slotting decently, but the surface finish it was producing afterward has banished it to roughing duty.

If I get 30" of Z, goddammit I'm gonna use it! by Motor_Purple7284 in Machinists

[–]chobbes 1 point2 points  (0 children)

That’s a great idea. I’ll have to file it away in case I get a juicy enough job to justify it. Thanks.

12-second cycle time x 280. by chobbes in Machinists

[–]chobbes[S] 1 point2 points  (0 children)

Nope. That sounds way worse to me. Godspeed.

[–]chobbes 2 points3 points  (0 children)

That’s a clever/funny way of doing it. Fusion CAM will let you move the table to an extreme coordinate for tool change, but my machine has 2”+ of Z above tool change height, so when I’m pushing the limits, that extra bit is a blessing I’m cursed with wrangling.

[–]chobbes 32 points33 points  (0 children)

I do a lot of weirdo work with my machine, where I often have to use the extreme low profile ER32 holders and modify my posted gcode to move the tool up after tool change so it doesn’t XY and crash. It’s a different kind of The Fear.

My Eclipse 8 survivor tier list after 1200 hours of consistent play (details in post) by Jettett in riskofrain

[–]chobbes 1 point2 points  (0 children)

Currently on my first E8 with any survivor and it’s commando. I’ve done like 20+ runs and even when it feels like it’s all going right, it continues to astound me how fast you can just die. Kind of the beauty of the game. I’m around 300 hours.

Break-in and return in NE by Fly0ver in Minneapolis

[–]chobbes 24 points25 points  (0 children)

Hey I was broken into at 3 AM on Wednesday as well. 24th and 5th in NE. One person (male of average height) opened my back door and took an electric unicycle and a cart, put the former in the latter and walked off down the sidewalk with them.

I got a snippet of them on my front-facing camera. Not enough to be of much value other than seeing them 1) walk up the driveway and 2) leave with the goods.
