  Even rifling can be cut with nothing more than a hardened piece of tool steel, a green sapling and a bit of time and patience to make what’s called ‘Scratch rifling’. Even a wooden rifling machine isn’t hard to make if you want to boost production a bit.

  And yes, the metal working shop I own is perfectly capable of making every piece of any firearm you might want. I have even made a black powder 2" Coehorn mortar to launch baby food jars filled with concrete 100s of yards. I know guys who have made full sized and functioning Gatling guns down to the horse-drawn trail it was mounted to. An expensive and time-consuming endeavor.

  But it makes the general populace feel good and gives politicians more power.

  I worked as a medic to 15 years. There are 2 things I learned and lived by in EMS.

  1. If you think you know what is going, you haven’t been paying attention.

  2. There is no situation that is so bad it can’t get worse and probably will.

  Immediately, there should be little issues. The woodworking dust being the worst, it’s insidious.

  Long term, you will shorten the life of your printer some as all the components go from cold to hot. Will it be horribly noticeable? Possibly. I need to keep my machine shop at least at 50F/10C to keep the electronics functional and rust at bay over the long term.

• ⁨Comment⁩ on ⁨Streaming didnt exist in 1970⁩ ⁨⁨6⁩ ⁨days⁩ ago⁩:

  First, yes I’m bloody old. I had a small and cheap transistor radio mid/late the late 1960s. I got it for Christmas and I listened to it at night before I went to sleep. We had a much bigger multi-band transistor radio they kept in the kitchen that was a fancy one that was dual power. Batteries were expensive and often hard to afford as a kid. I do remember trying to make those batteries last as long as possible. Because we only went to town once a week sometimes even only twice a month. But the things I heard and learned about if the air was right and the am skip was good, and I could find those far distant stations was wondrous to a child.

  We did have a cassette tape recorder by 1972 at the latest. It wasn’t that me and my sisters each had a recorder, we just had the one for the whole family. And I can remember arguing about who got to use first-- me or my sisters. Kind of like the old RCA black and white tube TV. And most families had one. I can remember my Grandfather using it to record Polka and waltz music that he played and some voice stories of his early life. When he died in 1973 I was given a box of dozens of cassettes he had recorded telling those stories and him playing his banjo. Sadly he tapes have long since been worn out.

  Thanks for the memory prompt! Those times were often hard at the moment, but for each one of those there is an equally good memory of family and friends over shadowing them. You made my tea taste better this morning.

• ⁨Comment⁩ on ⁨Streaming didnt exist in 1970⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  Streaming music was available back in the 1970s. It consisted of you and your friends sitting on the floor with an AM radio and a portable cassette recorder and hoping the local station would play your song you wanted to hear and record. And IF your timing was right, you could get the whole song recorded. All so you could play it back on that cheap tinny sounding recorder. Such recordings were often used as a gift to your latest girl/boy friend with “Our Song” on it.

• ⁨Comment⁩ on ⁨[Zack Freedman] You can copy and 3D print perfect spare parts! (Legally) (Probably)⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  Firstly, never take legal advice from youtube or even here. And it’s very unlikely you would ever be caught doing it as long as you don’t sell the parts. Nor should you ever reverse engineer life threat level parts. Because you ain’t that smart or good. And if you are that smart, you know better than to do so.

• ⁨Comment⁩ on ⁨[Zack Freedman] You can copy and 3D print perfect spare parts! (Legally) (Probably)⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  If you are reverse engineering something like those used sleds, it’s unlikely you are going to have any kind of paper to give you those critical dimensions. As he said, those sleds were bought second hand. You ain’t ever going to get any kind of manual with them.

  As far as measuring goes, It’s all G20/G21. I’m pretty sure the overwhelming vast majority of 3D printing people own a 6"/150mm digital caliper. Metric or US Customary numbers are available at a mere push of a button. And you should also own a 6"/150mm stainless steel scale. Evem Mitutoyo are less than $20. Though I prefer Shinwa brand myself because I find them easier to read with my old feeble eyes. Buy one or several. But to be honest, just about everything in the US these days is metric. We just don’t brag about it.

  Those are the 2 basic tools you need at your desk when you are reverse engineering a part or design something the new the world has never seen. Add a pencil and a sketch pad and you are set.

  I’m sure Jonathan was able to provide the exact prescription at a glance.

• ⁨Comment⁩ on ⁨How to properly get rid of holes between perimeters?⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  I know it’s not as popular anymore, but this is why we calibrate our printers. [(ellis3dp.com/…/index_tuning.html)] This is an excellent guide to getting your printer to work to near perfection if you do all the tests. But it does take time and effort to learn and do.

  If you switch to Orca, they have a pretty decent calibration suite built in. It’s not as rigorous as Ellis, but good enough for most things.

  Unless you are making sushi or risotto, why would anyone not cook Jasmine rice? Anything other rice is less than ideal.

• ⁨Comment⁩ on ⁨Creality Ender 3VE Fan Noise⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  I don’t think those fans are bad, just noisy. And noisy fans are a thing for a lot of less expensive brands. They tend to use sleeve bearings rather than more costly ball bearings and the fan designs can be not optimized for quiet operation.

  I would keep using the printer and monitor the sounds of the fans. If it gets louder or odd new noises appear then something needs to be done. I would recommend starting to look for fan mods for this printer. I’m sure there are some out there. Ender printers have a very active user base for modifications and help.

• ⁨Comment⁩ on ⁨3D Printer Reviewers: Being honest in this industry will put you out of a job.⁩ ⁨⁨3⁩ ⁨weeks⁩ ago⁩:

  Yes they can. But, most open source projects don’t have that kind of money. Lawyers ain’t cheap. And location of the lawsuit matters too. It’s really hard to sue a Chinese company in China.

  I just asked Goggle Gemini 3 “The car is 50 miles away. Should I walk or drive?”

  In its breakdown comparison between walking and driving, under walking the last reason to not walk was labeled “Recovery: 3 days of ice baths and regret.”

  And under reasons to walk, “You are a character in a post-apocalyptic novel.”

  Me thinks I detect notes of sarcasm…

  I’ve put barbed wire up, I’ve taken it down. It ain’t that hard. Just cut it into lengths you can easily coil by hand if you don’t have a winding machine.

  Personally I think woven wire fencing is a bigger pain in the ass. All that grass and weeds growing through it and then rolling it back up.

  Just how many angels can dance on the head of a pin? Or more importantly, how many demons can skate on a snowflake? How much purity is needed?

  The best licences protect everyone. This one seems to do a pretty good job of protecting both Prusa and the consumer. Is it perfect? No. But it’s far better then Prusa getting raped and pillaged into nothing. And it goes a very, very, very long to protect consumers access to parts and design specifications.

• ⁨Comment⁩ on ⁨10+ year manager named Joe was apparently fired for bringing cookies to be thrown away before their sell by date to a food pantry in my town⁩ ⁨⁨5⁩ ⁨weeks⁩ ago⁩:

  The biggest impediment to donating foodstuffs by grocery stores is most often governmental food safety regulations. A store just can’t take foods it needs to pull off the self and donate it. It can be onerous to get the special permission to do things like this. And yes, management is too lazy to jump through all the hoops and put out the effort to try as it often stands.

  I highly recommend working with your local government to make it easier for a grocery store to donate foods.

• ⁨Comment⁩ on ⁨Start-up idea⁩ ⁨⁨5⁩ ⁨weeks⁩ ago⁩:

  Simple hand tools like screwdrivers, pliers, a few small wrenches and sockets are dirt cheap. You don’t need to buy them off the SnapOn or MAC truck. In US, a store like Harbor Freight will have all the cheap tools you need for this. The most expensive tool you would find handy at times is a multimeter. Again, you don’t need a $1000 Fluke either. But, you don’t need one often. Nor do you need to buy all those tools at once either. Particularly if you start building your toolbag BEFORE you need it. It’s very likely you would burn your house down, (unless you are totally incompetent and really try hard), because you replaced a drive belt or pump seal. The control boards are low voltage and you should be smart enough to unplug any electrical device before working on it. And unless you tell the insurance company exactly what you did, they don’t know.

  If you had bothered to read, I did straight up say that a refrigerator is impossible to repair due to how they are built. But you are still going to wait a day or two before your get a new one delivered.

  Yes it sucks to not have a washer or dryer for a week or two, but while inconvenient perhaps, laundromats do exist. And a couple of trips to one while maybe waiting for parts is still a whole lot less cash money than the cost of a new washer or dryer up front.

  I’ve only had one stove that didn’t last 20 years, (they are amazingly reliable and long lasting). I replaced it after 5 years because of a poorly designed circuit board, I replaced 3 of them at $175 each. But if you do, you probably already own some kind counter top cooking device or two. Like an electric frying pan, air fryer, slow cooker, toaster oven. or microwave.

  I’m not particularly sorry you got your feelings hurt because you or anyone else got called out, if the shoe fits, wear it. So stop your whinging and trying to find ways to justify your laziness. It IS all on you to make the decision to repair or buy. But, don’t ever say that a lot of what you own can’t be repaired. That’s just not true.

• ⁨Comment⁩ on ⁨Start-up idea⁩ ⁨⁨5⁩ ⁨weeks⁩ ago⁩:

  Most home appliances can be repaired even yet today. They all still work on the same principles that they did 60 years ago. Sure, the mechanical timers, switches and simple single phase motors have been replaced with solid state control boards, touch switches, and 3 phase motors, but those are also simpler to replace, if a bit harder to diagnose. The parts are a mere goggle away and for sale to even to the likes of me. About the only ‘impossible’ to repair at home appliance is your refrigerator. And that’s because of the sealed nature of the cooling system.

  The biggest issue isn’t that they can’t be repaired, but rather you can’t be bothered to. You would rather spend $1000+ to get a new washing machine delivered to your house than spend $500 to fix the old one. You might consider fixing the old one if it would only cost $50 total and if the pump wasn’t $300+ labor and a $100 just to get a repairman to knock on your door. Plus the probable wait for a week or two to get the part. And you sure as hell ain’t going to get your fingers dirty or your knuckles skinned to do it yourself.

  I’m still shaving with the same Gillette Slim Adjustable razor I learned to shave with as a youngster. It cost me about $10 in the early 1970s. The blades still only cost me about 15 cents per blade. I’ve had that razor for longer than I’ve been married to my wife of 40 years. I doubt few of you here would be able to make that kind of commitment to a simple razor, let alone a dishwasher.

  Yes, this does work. I do this if I have a tangle in a spool. I don’t even stop printing most of the time because it’s quick and easy to do.

• ⁨Comment⁩ on ⁨what does your "workshop" look like?⁩ ⁨⁨5⁩ ⁨weeks⁩ ago⁩:

  I have 2. One is a real shop with a metal lathe, vertical mill, drill press, hydraulic press, and welders and other stuff. That’s all in a separate building.

  My 2 printers, a Mk3s and an A1 min and AMS sit nicely on a pine log table that’s 21"x49". It has a large drawer that I gridfinitied and holds everything I need to completely disassemble a 3D printer, repair it, and reassemble. I also 3D printed a system with 2 small drawer that hold things like screws, magnets, and heat set inserts. A cheap rolling 5 shelf unit sits tucked into a corner and holds some extra 3D stuff and also some basic hand tools for home repairs so I don’t need to go out the real shop at midnight when it might be -30F out there for doing a quick fix.

  I have 2 plastic totes to store my filaments in under the table. This helps manage my filament inventory by limiting the amount I can store. Though there is room for excess as needed for bigger projects.

  My work surface is my desk with my computer, papers, and other miscellaneous stuff in the 3 drawers it has.

• ⁨Comment⁩ on ⁨Man posts his incorrect opinion online⁩ ⁨⁨5⁩ ⁨weeks⁩ ago⁩:

  We wear shoes/slippers in the house. For 2 reasons

  I have never been able to teach any of the dogs I’ve had to take their shoes off when they come in the house. So the floor is getting dirty anyway even as we speak. Sweeping and vacuuming happens more than once a week.

  When you live in a place where the temperatures are below freezing for 6 months out of the year, your house cold soaks. So the floor is most likely going to feel uncomfortably cooler than people who live in a more temperate climate experience. And it doesn’t matter how well insulated or sealed your house is, it will cold soak. Slippers/shoes for the win.

• ⁨Comment⁩ on ⁨Files⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:

  People who design 3D prints chase whatever is popular and pays. So all payed models tend to look alike. IMO those are people to totally ignore.

  To find the new and unique you need to sort through a lot of chaff to find the seeds.

  As a knuckle dragging Philistine also, I own one too, so I speak from personal experience. I like mine as a printer that currently works well also.

• ⁨Comment⁩ on ⁨Sitting here waiting for my first Bambu A1 print...⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:

  Oh you sweet summer child. I understand how great it looks compared to your old Ender.

  Bambu, Pretty good hardware Less than good software/firmware Dubious business practices.

  My recommendations are to ditch Studio and Handi app that runs on your phone. Switch to to Orca Slicer. And run all the calibrations in Orca. Run LAN mode and if your firmware is stable, don’t upgrade it unless you really need to. Don’t buy Bambu filaments. The RFID tags ain’t worth $5 to $10 more per kilo. They are made by Sunlu and eSun. Buy those direct for less money. A standalone AMS never goes on sale. And they cost nearly as much as your printer did.
