would something like pic related (1/8" carbide bit) work to help me cut a 5mm aluminum plate? i have a 24 tpi hacksaw but it didn't go very well, probably due to inexperience and my vise being an undersized piece of crap. i have a dremel with a router attachment so i was thinking an end mill style bit, single flute to avoid getting clogged by aluminum, might work.
why not use a cut off disc?
>>2959314go to the junk store and buy a $5 jigsaw
>>2959356i just realized my hacksaw blade is 32 tpi so no wonder it plugged up. maybe i'll try 18 tpi.>>2959358heard they plug up easily and arent suited for aluminum. i only have the cheap shitty dremel cut off wheels which are barely usable on 'hard' metals.>>2959359thought about this as well.
Too much schmoo in your kerf, bud
Use wd-40 or diesel fuel as cutting fluid for aluminum. Helps keep the aluminum from gumming up your teeth/flutes.

I live in a place with a lot of fossils, but boomers have already picked up almost everything decades ago. Is there a small and portable set of tools I could bring with me on my hikes to split open small rocks or break away parts of bigger ones?

Now that winter is starting to settle in I'll be focused more on inside projects for a while. But one of my next big stone projects is going to be building a stone bunker to serve as a turbine pit. I'm currently designing and building a piece of equipment that will rotate a 1 foot diameter component at 50,000RPM (picrelated). I'll be double checking those burst pressure calculations, but would rather not find out I was off by a factor of 10 or something the hard way. So current plan is-stone walls for exterior-stone walls for interior-dirt bags in between stone walls-steel I-beams for roof support-deck-planks to bridge gaps between I beams-dirt bags on roofGoal is to maximize blast protection per $ spent without looking like WW1 warzone. I considered things such as felling trees and even unironically free pallets, but quickly came to the conclusion the latter was too labor intensive. So if anyone has other ideas I'm interested.I realize I could probably start a new thread, but have a feeling it would get derailed quickly.
Where can I find a decent kit for mounting an antenna to a chimney?Because I can't find anything that doesn't use the same exact stock image copy and pasted over and over again, with reportedly varying quality, and almost none of them even contain shims or plates for the corners of the chimney.I would've used pic related t-style brackets, but any listing I've found of this doesn't even have a way to tighten the steel straps to the chimneys.
>>2959349It's a really big TV antenna I need it to support.
>>2959212Unistrut sandwich?
>>2959375I don't know if this can be better tightened than steel straps to the chimney without it sliding around or damaging the chimney.
>>2959383>damaging the chimney.That's the bigger risk IMO. I've never had a real brick chimney so I couldn't tell you
>>2959386It might even be easier to just buy steel strapping tools, all my neighbors appear to have their antennas attached to their chimneys with steel straps anyway, and some setups are over 50 years old.You know why I can't find brackets with ratchets built in? My guess is there was probably one company that had a patent for them, and they're probably out of business now.
Twenty years ago, I was a kid and wrote a bunch of mean shit on the walls of my relative. It still existed - and upto this day, and I just learned that you can remove paint/old shit from your walls by applying toothpaste and perfume along with soap onto the affected area, and rubbing it with a great intensity with four fingers. Just thought this would be useful in case anybody encountered my issue. I'm a fucking adult today, and I wouldn't want anybody walking into the room and reacting to it like what'd happened to me. Godspeed.
>>2955943Which kind of perfume, does it actually matter?If it doesn't, then is it just really the alcohol or whatever solvent that's in it that matters? You could probably buy that separately.
>>2958069>big paint HATES this trick

I have slightly overfilled the oil on my car, how would you go about draining only a slight bit of it? Remove the oil filter and drain it a couple of times?>pic related
>>2958994the excess will burn offtoo high a level of oil in the pan splashes extra oil on the cylinder walls, which overcomes the designed oil flow capability of the rings, which means extra oil is left behind on the cylinder walls as the piston moves downwards. This extra oil is then exposed to the combustion of the fuel charge, and it becomes smoke and goes out the tailpipe. The extra carbon residue may darken your oil a little prematurely, but it's not worth changing your oil change schedule over.
>>2958994thats nothing. dipsticks vary in length more than thati bought a b5.5 passat a bunch of years back to commute in and the 1st oil change it took 2 pans to drain. so i check the book and it says 5.3qt or something and i put it in and its not even on the stick. wtf? so i think for a minute and then look at a yootoob and the finger pull on the vid stick is completely different. somebody had put a wrong dipstick in it at an unknown previous point. i ordered a new oem one and it was like 2.5" longer than what was in it. that engine had been chugging along just fine with like 3 extra qts of oil. and the milage went up about 4mpg from the reduced windage
>>2959020This. That’s nothing. Start the engine and check it after shutting the car off and you’ll be at “full” with some oil spread around.Or go hot rod it and try to brapp off some oil

When I try to remove severed bolts using a regular drill bit and bolt extractor, it almost never works. It only works like 1 out of 10 times if I’m lucky.Do left drill hand drill bits work? How many times out of 10 would you estimate does it work?
>>2957161>They drill holes when you can't use a right-hand bit for whatever reason.Name one reason you couldn't use a right hand twist bit and could instead use a left hand twist bit. They are sold specifically for removing broken off bolts.

Absolutely NOT a "tech guy". 45y/o tradeworker, left off at DOS & Qbasic in '93. Found some 2016 tech during eviction remodel: 2016 Galaxy Tab-A and 2016 HP Stream 11. Do not be fooled; all the "tekkie lingo", specs and processes I will be citing are new to me, learned over the course of these projects. I knew absolutely fuck-all about it before I started.SM-T580 tablet has 2gb ram. when found, it was running Android Oreo. slow as shit and no storage space for anything. I could surf the web and shitpost on Chan, but had no space for memes, Pepes and/or videos. did lots of research and relied on Grok for a fair amount of process. that said, NOTHING was easy aboot this... for me. I found the tablet and craptop last December. tablet has been in a bedside table since it had no storage and was too slow to be of practical use. I will try to outline the entire 2 day ordeal (15 fucking hours) as succinct and condensed as possible. I found a 32GB micro SDHC card while tearing oot the carpet & padding in a remodel. my first thought was "COOL! I can double the eMMC storage on my Linux Stream Craptop!" however, after a quick discussion with Grok, I decided my first use of it would be to flash a new OS onto the Samsung Tablet. did a little research into available OS options and learned aboot the basic hardware/software that operates little phones, tablets, etc. quite different from "regular" computers, it turns oot. Decided on "LineageOS" for what is essentially a clone of Android 13 but with full current patch and security support. I found the Lineage file on some website, perhaps Github, unsure exactly where. I was also told that I needed to I stall "MindTheGapps" to access Google app store and run anything other than basic web browser on it. I started my questionable journey at 8:00 Saturday morning. I wrote the aforementioned files onto SD then connected tablet to craptop via USB data cable, which I used to install something called TWRP by "TeamWin".

since this post came back from the dead, I'll update with my latest freebie score: FINTIE folio keyboard folio FREE from Amazon Vine. it's not for my exact model, so the tablet clamp brackets are ~1mm too wide, but it has a mediocre magnetic hold and I added two 2cm squares of velcro tape on one side, then just use the clamp brackets on the other side with a bit of added magnetic assist. works perfect. no one would ever notice its not an exact match. camera cutout does not line up, but whatever... I can pop the tablet out in .2 seconds and I rarely take photos with it anyway. The Bluetooth keyboard works perfect.perfect timing for zombie post to come shambling back to page 1, since the folio protective case and keyboard arrived tonight.as for>>2957247that's fine. we are 90% debt free. we only owe $75k on our mortgage. when that's paid off, I'm scaling back.

>>2959047>PayingSomething having a high monetary value doesn't imply that somebody is paying that monetary value. In fact it's better that they get it for free because people all fucking retarded and would gladly let a trojan horse into their homes if you sell it at a discount. Unitree makes the robots and part of their funding is from the Chinese Communist party. Article 7 of the Chinese National Intelligence law requires all organizations and citizens to comply with state data collection demands. That means if the CCP wants to access the various sensors of the network of robots, they can. And so the question becomes, how much is a bipedal remotely controllable robot that can self destructs at will worth to an intelligence organization? The answer was provided by that poster that you think needs to be Chinese. In reality you just need common sense. Honestly it would be better if you were ESL. Now you're just being obtuse at best and retarded at worst.
>>2959051It's a nice sounding bit of conjecture, but where is your proof that these values given are based on anything at all?Where are you pulling this "self destruct at will" stuff from too? How do you suppose that will work, and how will it be better than just sending a person to cause harm?The truth is, it would be fairly easy for a state to kill almost anyone on Earth. Just look at the United Healthcare CEO assassination as an example of how you don't even need state-level resources, then look at some more extreme cases like Iranian scientists being killed by Israel, which can get very advanced. The problem is it's usually easy to trace that killing back to a state, which has significant political implications, and is generally more trouble than its worth.The CCP using a Chinese made robot to somehow (unspecified how at the moment) kill a person has got to be one of the most traceable methods available.>Honestly it would be better if you were ESL. Now you're just being obtuse at best and retarded at worst.There's no point in trading petty insults.
>>2959051>>2959065And a bit more as well because you still haven't addressed this. Why is Unitree, the CCP, or anyone else, making this password stealing killer robot stuff known to anyone at all, and why is that person then posting what would be a globally significant secret here?Use Occam's Razor. Which is more likely? What you are proposing, or a fake post?
>>2959007No I'm a White American who's a contractor and works in robotics. That estimated value per robot was taken from an investigation on companies selling humanoids at a loss like optimus, unitree and neo. We cannot even come close in price ours will be close to 50k (industrial market who need a larger and stronger bot over other offerings), which is almost double from others. BTW almost everything on that list is illegal, but if you really think that's going to stop anyone even someone like Tesla, I have a bridge to sell you. Tesla/Amazon/Google/Apple already siphon insane amounts of data, much of which would be considered illegal. Unitree doing the same is no different. The killer robot stuff is a meme but it's still a real possibility. If you can't realize this, you deserve to be robo executed. >>2959024>MUH LAWSDo you realize no one gives a fuck? This era is literal silent WW3, the information war. If you think adversaries who want nothing more for your country to fail and for you to die are going to follow your laws, I have a second bridge to sell you.>>2959066>Why is Unitree, the CCP, or anyone else, making this password stealing killer robot stuff known to anyone at allIf you actually look into it, it was discovered, Unitree/CCP weren't advertising they have security vulnerabilities and are siphoning data. You're arguing against strawmen. They were caught doing it and didn't fix it. This proves the security stuff is intentional and when questioned on the data being sent back, they never responded, which proves they don't want to talk about what's being captured at all.that list is just a bunch of stuff that CAN be stolen via a robot, not that this is exactly what was found to be stolen.Comment too long.

>>2959205>No I'm a White American who's a contractor and works in robotics.I believed that to be so. The clause about you being Chinese is part of the question posed to the other poster. I think that might be part of why he and I were not able to talk properly, because he thought that was something I was claiming, and only the second part was a question.>That estimated value per robot was taken from an investigation on companies selling humanoids at a loss like optimus, unitree and neo.This would have been a lot clearer if we knew these were speculative values rather than planned values.>The killer robot stuff is a meme but it's still a real possibility. If you can't realize this, you deserve to be robo executed.It's a possibility in the same way that any type of assassination is a possibility. People get all worked up about robots because they've seen too many scifi movies. If a state wants you killed, they already have a way of autonomously moving and firing a gun. A man with a gun. They're not going to be mass executing civilians with these things anyway. Maybe they can clumsily execute one or two people before everyone catches on, and then we all switch off our robo maids. It's a one and done technique that requires a whole industry to be built up and then knocked down again after use. There are far easier ways for a state to assassinate basically anyone that already exist and are in use. e.g. Novichok assassinations.>This era is literal silent WW3, the information war.Metal Gear Solid.Sure, China isn't going to follow laws it doesn't want, and I found most of the rest of your post believable because of that, but after a point in a BCA breaking the law has a higher cost in terms of detection, reputation loss, and product disuse than benefit. The password stealing one crosses that line, and when I replied about laws it seemed your post was purporting to contain actual budget values rather than speculative ones. That was the claim that was unbelievable.
Can you cut down a fiberglass handle like this, or is it going to perpetually shed off bits of fiberglass after that?If so, would throwing tape around the handle and some epoxy on the bottom fix the issue, or is it just structurally compromised?
>>2959084Anything carbide or harder should work. Remember that glass (and carbon for that matter) are ceramics, and the cut should be handled the same. It's slightly easier, because the epoxy matrix prevents crack propagation much better than pure ceramic.
>>2959099Thanks!
>>2959084Any standard abrasive metal cutting wheel sold for an angle grinder will work just fine. I dunno what the other anon is smoking saying you need a carbide blade...
>>2958459Can't you just get an adz and cut down the handle on it? What are you gaining by doing it this way?
>>2959189If you use a softer abrasive, you increase the risk of fiber pull-out, and your cut won't be as clean.

>>2958858These welds are cold as shit. The hole is definitely not your major problem. Any load on these and they will crack just right off.>>2958931You'd need to cut out the tube and weld a new piece in. The material you are showing is rust only.For someone who has never welded before I say forget it. You are going to inflict more damage than you'd be able to repair.You'd have to weld overhead on rather thin material. Clean and cut it thoroughly. Know your parameters and your technique well, or the heat might spread on and set your car on fire. Definitely not a noob job.

Asking here because bepis has an autistic knowledge of power tools and deals Anything decent in the ridgid lineup for Black Friday this year? I know 2024 was all about ridgid using tabless 21700 cells in their 4ah Max output exp line But I’m just on their cheap ass brushed tools so I won’t see any benefits probably Anything else that’s a major pickup ?
>>2957693Because you called my name…The Octane and other Max Output packs have the second set of + and - contacts. The lower draw tools typically don’t have the second set of contacts to match the high demand packs. So… I have no clue.Better cells = less voltage drop under heavy loads = more powah. That’s a big ol’ bit they’re running in that test though. I don’t even care anymore. I’m currently fighting the battle to make them buy OE DeWalt packs because Chinese 9.0Ah packs are never really 9.0Ah.

I’m the buyer for a company and they just don’t let me buy good shit… they make ass backwards decisions they will risk damaging tools to save $3 But then a “emergency “ part order where they overnight a part and leave it on a desk for a month
>>2957711And thank you for the info, I did some digging and I missed the deal… 2 of the old octane 3.0ah batteries for $49.95 which is the only battery pack from the octane line that used 21750 cells apparently? So was hoping I don’t miss on anything else since every battery I have right now is just a basic bitch 18650 cell

Long time listener, first time caller here; I am in the process of relocating my hot water heater. It's a 1920s house with crawl space and all copper piping. In my picture, I have taken a length of 3/4" copper pipe and annealed it along about 18" and have used a conduit bender to no success here. As you can see, it has been a bit flattened on the radius. My thinking is that having a gradual radius vs a 90 degree fitting will alleviate any water hammering on the corner of a 90 degree fitting, therefore lengthening the life of my new pipe. Thoughts? Is this completely retarded of an idea? Nothing has been installed yet and I want to make sure this pipe lasts.

>>2959120Most of the problem has been with “plasticizers” not the plastic itself.As far as I understand, pex doesn’t have any plasticizers.Polyethylene and polypropylene line milk cartons, drinking boxes, and your main water line is probably polyethylene, too.The main constituent is ethylene gas, which plants emit and are involved in the fruit ripening process.I’m worried about a lot of other things: super chlorination, bpa/s/f, teflon precursors, legionnaire’s disease, but not pex. I did quite a bit of research.
