I have an interview for a shot peening engineer position tomorrow. Send me your best advice!

I am a female fresh mechanical engineering graduate and tomorrow I have an online interview with a local manufacturing company for a shot peening engineer position. I have only just known about this particular machine for the past three days, I have done some studies for it so that I’ll be able to understand the mechanism. I have no prior work experience nor an engineering internship. I think I have prepared myself for about 60%. How about some extra advice from you guys? Thank you in advance!

Looking for a way to test shot peening media humidity

I'm currently investigating on a shot peening problem. Our first guess right now is humidity in the media (round metallic particles with a diameter around 0.010"). I'm looking for a way to test the humidity in the media on different samples we take in different spots in the machine. We could make a lab analysis (that's what we do now) but we want something "on the spot". What would be the best hand-held instrument to test the humidity in a "powder-like" material?

For now, I found those : http://www.rotronic-usa.com/products/water-activity/hc2-aw/ It looks like it would do the job but what do you guys think?

Update: seems like I've been banned for 7 days for spamming, good luck and do your own DD to all those who DRS-ed your IRAs with custodians, hope you don't get screwed

I won't be able to reply, so DM me or tag me in another sub. I'll continue to update this post with evidence gathered by other apes so if anyone wants to carry the torch to make a new post, you will be able to

>She had a hard time understanding why I was asking all this so that’s the best answer I could get. I was unable to get the chat bot to connect me to a human. I’m going to send an email to them now asking the same questions. I did ask about talking to someone higher up, but she wasn’t able to.

>This leaves the question can shares that have been withdrawn from the DTC but held by the custodian be somehow lent out by the custodian? I’m not sure how they could be if they’re in book entry form and not at the DTC. I will try to get a better answer by email.

EDIT6: /u/Parris-2rs (context) and /u/_foo-bar_ (context) have taken it upon themselves to check with ComputerShare and provide evidence to the contrary. Let's patiently await to hear from them on Monday. I'll update this post (and likely make a new one) once they share their findings with us.

A Theory on Barrel Life and Throat Erosion (Long-- no TL;DR)

If you're a high volume shooter, you should care about barrel life. For many calibers barrel life is second only to projectile cost for per-round cost of shooting. (Amortize a $600 barrel across 2000 rounds sometime).

Even if you are financially positioned to not care about per-round costs, you should care about keeping a fantastic shooting barrel alive, and care about it shooting with that load you worked so hard to develop instead of having to swap barrels and redo your development with fingers crosses the new one likes the old load or similar loads.

I'm neither a metallurgist nor an expert on high pressure dynamics. But my engineering job involves working with extremely high pressures (up to 3000 bar at times) and dealing with how parts fail when exposed to heat, pressure, and flow. I know a little bit of metallurgy and how pressure vessels fail. I wanted to offer a couple points to think about, several of which I'm sure are review.

  • Barrel life varies a lot even within chambering. It's not as inherent to the chambering as many want to believe. You can kill a .308 in half the 5000+ rounds most will last. And you can baby a 243AI to 3000+ rounds. It's not necessarily true that the .308 is always a long lasting barrel and the .243AI is a goner in <1500 rounds.
  • Barrel life varies a lot with the opinion of the user and the application. I promise you that the barrel life of a 6PPC SR benchrest champion is a lot less than what a .243 varminter will get, even though the former uses less powder and is more efficient. The BR shooters buy many barrels at once.
  • Load matters a LOT. The choice of powder, the pressure it is loaded to-- can make a difference of 50% or more on barrel life. Don't expect your high nitro PowerPro40000MR loads to give barrel life like single base N165.

Now to the theory: barrel wear is mostly cause by microscopic tearing of the metal (microcracking) associated with expanding under pressure. Heat degrades the properties of the steel and exaggerates the effects of pressure.

The shiny bore we like to think is nice and smooth really isn't. It has tiny scratches in the surface visible under magnification. Each of these scratches is a place where the pressure can "pry" apart the metal at the scratch and open up a microscopic crack.

At work, we pressure test tubes ramping pressure up as high as 4500 bar (Higher than 338LM pressure) and down. With enough pressure change and enough cycles, you can make that tube split

Methods for Increasing Surface Roughness of Stainless Steel?

Hello - I’m working on a project involving 304 stainless steel sheet metal panels, and I need to increase the surface roughness of one side while maintaining the finish on the other. My google-fu is failing me, and everything I am coming across just points me to ways to decrease roughness/polish the surface.

My best thought at the moment is either shot peening or manually abrading it with a wire wheel or similar, although I will need to process a lot of these panels so scalable would be good. Are there any common processes I’m missing for increasing surface roughness of metal?

TIFU By revealing my Cock length to my family

Alright, so here’s the dealio.

I have a large Italian family with many cousins, uncles, aunts, nephews, et cetera. Every once in awhile we’ll all gather up to celebrate the anniversary of our great grandparents’ wedding, a special occasion marking the creation of our family. They’re long gone now, but it’s the memory that counts, and we celebrate by cooking a feast for the ages, rivaling thanksgiving dinner.

Now upon the eve of this anniversary all β€œda boys” (as us men in the family affectionately call ourselves) gather up and go to a famous local bar in downtown Boston. They only accept cash, very β€œold school” feel to the place, but it makes for some great stories. Usually the place is a blast, with all sorts of banter and drunken shenanigans occurring, but not last night...

Now before I divulge the details, I ought to give some background as to how I fit into this family. Where my father and I are well integrated into the family, my mother is quite the outsider. She comes from wealthier, southern origins, around the mid-Atlantic part of the country. Because of this, she’s always viewed the family as β€œworking class”, with her posh accent sticking out like a sore thumb at gatherings of Bostonians. By extension, I’ve always felt I had to prove to my family that I can β€œhang” with them so to speak, and in a way I worry that they see my mom as the woman who pulled my dad away from their tight knit circle.

Now let’s cut back to last night at the bar. Laughs, drinks, and stories all around the bar as we enjoy ourselves. My cousin Vinny invites me and some of the younger guys to play truth or drink. At this point I’m already quite drunk, but accept for the fun of it. A few questions in and Vinny asks me β€œhow big is your dick? I know you’re packing a huge one Anon, right?”

Of course my other cousins all groan with embarrassment, but I foolishly answer instantly, unaware of the ramifications of my response.

β€œ4.5 inches” I say too confidently, and suddenly all eyes are on me.

β€œDrink anon, I know you’re bullshitting me man!” says Vinny, with a twinge of nervous angst in his voice.

β€œI’m serious Vin, that’s all I got, haha”

Dead silence. I gaze across the bar to see my entire family looking in shock and awe at my response. Vinny attempts to get everyone focused back on the game, and everyone resumes at a quieter tempo, but I knew that I had just majorly fucked up.

After leaving the bar, my uncle Paul pulls me aside, puts both hands on my shoulder and says

[WTS][CAN] CG Shot-Peened Copper L2G2

Pictures

CG Shot-Peened Level 2 Gen 2 anchor handle

This is a one of a kind razor. Brian at Charcoal Goods has only produced a small (less than 10) batch of copper razors in this finish. He has mentioned he may do another run of this finish at some point. This is the only anchor handle razor that exists in said finish.

The first couple photos are of the razor when I first received it. The later show the patina that has been developing. All original box and materials included (as shown).

Selling because I prefer the level 3 shave (but the finish and material on this is better than my brass level 3!)

Paid $295 USD followed by taxes and duties at the border. Asking $300 USD and I will cover the cost of shipping and tracking from Canada. PayPal F&F or you add 4% for G&S.

SERIOUS: This subreddit needs to understand what a "dad joke" really means.

I don't want to step on anybody's toes here, but the amount of non-dad jokes here in this subreddit really annoys me. First of all, dad jokes CAN be NSFW, it clearly says so in the sub rules. Secondly, it doesn't automatically make it a dad joke if it's from a conversation between you and your child. Most importantly, the jokes that your CHILDREN tell YOU are not dad jokes. The point of a dad joke is that it's so cheesy only a dad who's trying to be funny would make such a joke. That's it. They are stupid plays on words, lame puns and so on. There has to be a clever pun or wordplay for it to be considered a dad joke.

Again, to all the fellow dads, I apologise if I'm sounding too harsh. But I just needed to get it off my chest.

Your IRA "DRS-ed" shares held in custody ARE BEING LENT OUT BEHIND YOUR BACKS? Find out for yourself

EDIT: Read my comments in the new post with new info by /u/Existing-Reference53

" to abide by reddit admin rules this post is missing lots of links, feel free to check my post history for links in another sub"

This post is gonna look very unworthy of it's flair, so feel free to do your own DD on the claims. If you know where to look ;)

Claim: Your IRA shares that you thought you DRS-ed with ComputerShare are not registered directly in your name if they are held For Benefit Of (FBO) you by a custodian. They are registered in the custodian's name and hence, are available for lending fuckery, and may not actually count towards the 5.2m shares revealed to us during GME's latest earning's report.

As long as the shares are not in your name, they can lend out your shares with or without your permission. See FIDELITY VS AER ADVISORS LAWSUIT

It says DRS invoice #: 0000000000000, so it's DRS-ed and the shares are registered in your name!

Yes, I hear you. Aside from the shady invoice number you're given that you should think about, the statement is provided by Ally.

Why does the statement being provided by Ally matter?

Ally was one of those brokers that turned off the buy button back in January. Can they really be trusted for what they tell you? Are they incentivized to convince you that your DRS-ed IRA shares are
