Those things are terrible. I’ve used them on a toilet paper holder and that’s about as far as it goes. The main appeal to them is not having to drill, but they leave a fuckheug hole and seem to hold less weight than pluge because they crumble the drywall while going in. Also they never sit totally flush, best you can do is like 1/16” off the wall, which hurts the strength more when you want to hang something that should butt up to the wall for support.

studs are under compression stress. replacing a section of the stud with a contiguous piece of metal would not impair its ability to withstand stress.

Nope, pretty much every TV I've seen still uses a direct to AC plug into the TV.

>>2896957
+1 on this. It’s always one of those PC style plugs. A couple recent ones have been a 90deg angle AC plug to make it easier to keep flush with the wall.

I want to get a shed in my yard to use as an office since my house is pretty small but I have a ton of land.

Now I am wondering if buying materials and building it myself would actually be cheaper than prefabs.

Obviously there is no upper limit to how expensive and intricate either can be but I'd like to keep it under 8k. The only thing I really care about is having enough room for a desk and for it to be waterproof. Windows would be nice too.

I am a construction worker and have worked on pretty much every part of house building but I'd be doing most of it alone.

I just feel like by the time I buy all the material for a small shed I'll be in the range of 10k anyways since I don't have the ability to bulk buy from cheap sellers like prefab makers.

>Also a great built. How weather resistant have you found it to be?

I built it to be well ventilated since my old shed sank into the mud and rotted. It has soffit and ridge vents and i probably over ventilated it for the hot months.

I have been in it quit a bit this winter with a kerosene heater but i plugged off the ridge and soffit vents to try to retain heat better. If it;s in the 40's the kerosene heater can get it about 60*. But if it's a very sunny day with sun coming though the windows it can get it up to 60* without the heater on. If it's colder than 40 i usually don't bother trying to work in it.

Nope, had a basic idea of what I wanted and made it up as I went. Don't do what I did.

Started mid-July and stopped end of October. Zero prior construction experience and mostly solo except for the roof. Probably would have saved a lot of time if I at least had drawn up some plans.

Infinite money glitch in the 80s if you can get permitted insurance is grandfather, couple big senators over the years brag about their beach properties not being fit for living in. Couple weeks of plywood work and a dehumidifier bring in a mold abatement team and get it appraised. Next storm that floods it you get like 70% of the home in rebuild funds rinse and repeat state tries to buy it off you to demolish it, but if you can keep it standing not livable just standing the state gives you its value in like three years. Major scam, I think the laws were written to stop utilities from undoing/breaking contracts on the edges of their territories, but the insurance companies get screwed and pass the buck to the state safety net who pays and pays.

Hey /diy/,

My current job involves a lot of designing and building control systems for machines, something I came into the job knowing nothing about. I've done a pretty good job of getting up to speed, but I'm constantly finding out about better solutions and hardware and best practices that I wasn't aware of.

Given that I have no formal education in automation, does anybody know of any good resources for learning more about the hardware side of things? I'd like to step my game up.

If so, you know practically everything you need to get a job as a PLC programmer. There's some other stuff you should learn, like how to use power control modules to control motors and solenoid valves, or how to connect a PLC to a network, but you can easily learn that on-site (either with the aid of a helpful mentor or watching YouTube video tutorials made by Pakistanis), so you really don't need a lot of math or knowledge of electromagnetic theory. If you don't know the bare mininum, I'd suggest at least taking a course or two on Basic Electricity and Electrical Machines at your local community college. I got my practical lessons on electricity when I had my first job, all taught to me by an extremely patient mentor, and eventually decided to learn other topics on my own, mostly from books and online courses.

I fucked up, I didn't cut this clean out down before pouring concrete. I tried removing concrete around the PVC with various methods but nothing is working well.

Several plumbing supply places say there is no flush clean out cover for this type of PVC, which is 4" DWV. They only make them for the belled end, which seems ridiculous.

Any good ideas on how to unfuck this?

We run across this all the time.
Chisel out around it, cut it off, and glue a threaded flange on it, then back fill it with concrete.

Although, I might back fill it with something else. Concrete shrinks a bit, you don’t want it to crack. You could pack it with caulking mixed with sand or something, as long as your excavation doesn’t look like a dog trying to exscape out of the backyard under the fence.

It's for a project that involves making precise adjustments by hand. And yes, the input shaft will have a knob to turn it. It will be similar in operation to a dual-speed telescope focuser where one speed is for getting the telescope roughly on target with the second speed for precise alignment.
>>
Technically possible, since a planetary can be driven from either side. However it really depends on how much force is required by whatever is connected to the output.
Might have to make the knob a substantial diameter for additional leverage.
Also, since high speed sounds like it's not an issue in this system, may be a good idea to open it up and replace the thick grease with a low viscosity oil to reduce the effort of operation.
>>
>>2896830
I have possibly that exact gearbox, or a very similar one, and it's easy to turn it just by holding the shaft, on either side. The only question is how much force you want coming out on the other side, since that's obviously transferred over.
>>
>>2896843
It's less about force and more about speed. I want to be able turn the knob 5° to make the apparatus turn 20 arc-seconds or, at most, 5 arc-minutes. I already have a 1:13 reduction using a 1.57-inch wheel to turn a 20.5-inch wheel by friction (or pulley and belt if friction between the wheel contact isn't enough). The added gearing will reduce that down even further.
>>
>>2896851
What does that have to do with speed? It's purely a question of gear ratio. The 64 ratio level 3 gearbox would get you right about there, with a total reduction of 1:832.
Ther's also some consideration for backlash, what they spec as backhaul gap, only that they don't say what unit the backlash is in. Possibly arc-minutes.
>>
>>2896854
>What does that have to do with speed?

A large gear reduction slows it down so you don't overshoot your targeted setting.

Generally you can do anything you want as long as you don't get caught. Don't go around bragging about your redneck engineering skills.
Anything you do that is sketchy will make you liable in case someone gets hurt. You should also remove anything jank you do if you plan to sell whatever on.

Do whatever you want - but there are reasons that planning permission and permits exist.
>>
Go for it. Worst case scenario a neighbor reports you for doing work, and the local permit authority comes out and slaps a stop work order on your project and tells you to go get a permit. Fines typically only come into play if you continue the work after they've told you to stop.

anyone do this and have tips or suggestions? I'm tired of paying $30+ for a shitty haircut and being forced to small talk.

i give myself an almost similar haircut to this.. I learned myself because I could rarely find barbers that could do it properly and also bc of the 35+ bucks every two weeks you spend if you care about your appearance.

I have normal clippers with left and right tapper, and use #10,8,6,4 and 1.

basically i fade the top part of the crown from 8-6 and then use the taper guards on the sides, then use the #4 to fade the line into the top part.. then I do 1 on the taper.. its probably 7/10 approximately to this one..

for the top I am still trying to find the right tool to get it right but for now I just eye ball it with the scissors and aim for all uniform length

I started cutting my own hair during covid when everything got shut down. It's a little intimidating at first but I got the hang of it pretty quick.I start out with a #6 (3/4") and get everything and then slowly fade down to a #1-1/2 (3/16") on the sides. When I started I had some crappy clippers from walmart, used them for a while and then got some nice Wahl cordless clippers and trimmer. It's nice not having to go to the barber once a month and I'm saving around $300 a year

Most of the tools we buy today are all manufactured in China, and just imported, assembled, local logo slapped, and marked up for 3 x's the price. What are some tools or gadgets you've bought from Chinese websites that turned out better than expected for your DIY projects and hobbies?

Post pics or screenshots of the item you bought and the price and whether it was good or a ripoff.

Optional: What else were you able to afford for your DIY because of the money you saved by buying from China? Can be more Chinese tools or something western made.

Yes, It was sponsored ad, with reviews that are 100% fake.
I said what the hell, I needed tools and if I got them individually it would cost around the same.
In reality you only need pliers, hammer, screw driver for most simple task around the house.
The drill was a nice add-on so I got it.
One of the batteries stopped charging, I opened it and the Li-Ion was corroded.
Several fine screwdrivers tips got bended when trying simple but torque heavy screws.
The drill bits are cheap metal, didn't do anything for a slightly sturdy surface.
All in all you got what you paid for.
I looked to the page again to try and get another battery, they blocked me.
There are new pages that sell the same stuff, under different names, but it's the same even the seller is the same guy.
My guess it's someone buy those at alibaba and re-sell it here
https://www.alibaba.com/product-detail/Professional-Factory-Cordless-Hammer-Drill-Machine_1600567860803.html

I have that one as well; got a keyless chuck for it (0.3-3.4 mm m8x0.75). It barely can cut through hard plastic/hard(ish) wood (it does, but you can barely put any pressure on it); battery lasts for mere minutes, and you can't use it while charging (mini usb, btw). Most importantly though, is that you better use some (very) heavily padded gloves (picrel: lambskin winter gloves); that shit vibrates like a bitch and you'll get your forearm tingling for quite a while...

I need to open up little ~1" holes in metal to get a recip blade started in it without cutting from the edge. Is a hole saw or a step bit being going to be faster/preferable for some other reason, or is there something else even better for this, that maybe doesn't cut a whole circle when I really just need an oval slot?
2 replies omitted. Click here to view.
>>
>>2894860
How thick of metal? If it's very thin, a step bit would probably be faster than a hole saw. You'll have to drill a pilot for the hole saw anyways, or clamp a guide to your material. If it's thicker material the hole saw will start to shine more. Also how many of these do you need to do?
>>
>>2894860
depending on the metal thickness:
- oscillating tool with metal-cutting blade
- plunge cut saw
- angle grinder
>>
>>2895822
- oxy acetylene with cutting attachment
>>
hole saw is easier and faster
get a 7/8 carbide saw and go slow with it

usually pop out a hole in 4-5 minutes. could make 100 holes without it getting dull. sheet metal ofcs

Seems like plunge cutting with a grinder seems like the best option
