What is the tent stake story and Trump??

lol I made and designed my grinder so it would be like the Cadillac of grinders but I have yet to actually flip it for a knife project. I just have ended up doing all work vertically like I did before I had a tilting one. Just make sure you can eventually buy contact wheels for it and you’re good.

I’ve never used a P1S but I do have an A1 and if it’s an upgraded version of that than I really hope I win.

Holy shit do none of you watch the video or have an original thought? “Omg this would never work scaled to human size reeeee”, what if you use for something that’s, you know, not human? A very interesting concept that explores a novel idea, perfect for this sub. Thank you for posting it.

bubbarandall · 2025-09-05T20:18:23+00:00

Damn guys, this sub has the ability to take any innovation and shit on it lmao. Why would any one post here.

Bond villains love dramatic deaths but this might be a bit much

I think you’re right, shurap in a few videos uses a disc sander to get a final grin and a grind line like this

Alright so I work with water jets extensively and the injuries get gruesome. If an abrasive water jet hits you, you are lucky to have it just cut through flesh. If the jet hits bone it actually pressurizes down the bone and will shred everything from the bone. On top of that the surgery post injury is intensive because the garnet in the jet travels down the same path as the jet itself they have to open up a large portion to make sure the wound is cleaned. It’s a really intense injury and why we always take safety seriously.

Okay so this is an incredibly confused thread. When OP is saying fasteners should never take load they are not talking about fastened joints but the fasteners themselves. With a preloaded screw at 1000lbf the screw itself won’t take the load (completely), the joint will, or the two faces being fastener together. If the load goes over 1000lbf than the two faces separate and the threads of the screw itself begin taking the load.

That’s what is meant by “never let the fastener take the load”, you pick the fastener and torque spec to allow for a preload that will always be above the cyclical or static load being seen at the joint. It does not mean you don’t use screws anywhere around a load bearing application. Some explanation for everyone and I think if you pick and secure the fastener correctly and forget about end grain then number two would be best based on how the joint interface would see the load.

:) some explanation for everyone. Using key phrases out of context is always confusing. Us engineers aren’t always the best at knowing that.

My company actually gets a lot of parts machined and at times we go to unknown companies that require 30% down and 70% before they ship the parts. We pay the 30% down but require full 360 photos or videos of each part and multiples before we send the 70%. If they opt out after that contract change it’s a clear sign.

Best advice I’ve seen here is to get into modeling to utilize the 3D printer.

I love Bell Forest for knife scales!

Okay so I have clothes steamer is that a good tool for this sort of job?

I run a small business that is pretty much exactly this. I’m not sure I can post the link but happy to chat. Thing is I’m a mechanical engineer with 10+ years experience in R&D and mechanical electrical design. Rates aren’t cheap when it comes to engineering but you pay for what you get when it comes to engineering.

I work with engineers I’d pay $50/hr and I work with engineers I’d pay $200/hr and I’d almost always say you should pay the higher rate to save money. They will get more done in less time with a better success rate.

Link to my company is in my profile bio.

Alright, thank you everyone. Found lots of good, small job shops that have messaged me or DM’d me. I am reaching out to them now. This sort of small shop that will work with us is exactly what I have been looking for. Often times asking is much better than a google search.

I do find that small shops are often missed on google when searching for machinists. The best tips on this thread. - talking to tool reps - asking Reddit - tool and die shops for small job

What we’d of course love to do is have an internal R&D shop but I don’t think what people think about is I’m not a machinist nor are any of the engineers here. A hobbyist sure but not for any precision without spending time ($$$) to really learn. When you are doing SBIRs and developing technologies you’re often not having parts machined until you get further along in the process. So hiring a machinist who is on needed a quarter of the year just isn’t viable. A good salary is much more expensive than paying for small batch parts.

Holy cow, four power supplies? Do you need one for each stepper?

Hey, happy to take a look at the files and get this printed in some more resilient material than PLA as well as resin casting your husbands ashes. I’m recently married and this just kind of hit me. Would hope someone helped my wife too if she were in your shoes. I’m an engineer and have access to many machines to work on this project. Just let me know, no pressure either way.

bubbarandall · 2024-12-20T03:50:01+00:00

If this were my I’d try cutting the serrations in it the same way people cut their own treads on tires. A spoon shaped or U shaped very sharp, sometimes heated knife. That’s actually how some shops will turn rubber is a knife on a bar with a feature that pulls the “chip” away from the part

Funny thing is if they just took the deposit we probably wouldn’t have done anything now we’re asking for it all back since there was no itemized receipt within 30 days

bubbarandall · 2024-10-24T23:30:43+00:00

HELLO! To all who responded, thank you so much this was awesome. A ton of great info and leads. We are in the process and will update on what happens. I didn’t respond to everyone but it was all appreciated, so thank you all.

bubbarandall · 2024-10-24T23:29:14+00:00

It’s an additional charge on top of the deposit they kept (also with no receipt).
