Its that time again boys, knife fags stay out.

Today's question, Does anyone here dislike the smell of metal?

Got a small box of a few pounds of brass I intend to cast into parts later. I've removed anything non-brass as best I could, but there are a few small bits of steel that are press-fit or otherwise permanently affixed to large chunks of brass.

What happens if I just say "fuck it" and toss those in as-is? Steel's melting point is much higher than brass, and its density lower. I'd imagine it would just float to the top to be skimmed off once the brass melted. At the same time, zinc outright boils before copper even melts, yet brass, you know...exists. Will I have any problem with the iron dissolving into the brass at a lower temperature than expected? Or any other issues removing iron from brass this way?

Oh, ok. Sorry, traction "high power compact" and drone-scale bike/skateboard "high power compact" are in different heat classes. I was convinced you were making a vehicle-sized hub motor. Yeah, using an existing stator and a custom rotor (mind the air gap!) With some good Neo should get you a good custom hub motor.

As for good magnet wire... unfortunately I know of the supply chain sources for industry and the "custom rewinding" shops where you sorta have to know somebody since they are doing this for very specialized equipment modifications that OEM rarely support. Turns out you can buy a $50k motor and rewind it for $20k+$1k in GOOD bearings to get a $200k motor

Are triple pane windows a meme?

>>2269268
The problem is if your windows are better than your walls the condensation happens at the next coldest thermal bridge ... the wall, which is great if you are a fan of "the last of us".
but if you don't like to mold, it's better to have condensate on glass instead inside the wall. so walls first windows second.

Also with some tile different lots do not match perfectly, so if you buy just enough planning to go back later if you run out, you might wind up with visibly different tiles, and the average autistic home owner will have a hissy fit.

Welcome to /wwg/! Here we discuss the working of wood and the tools and techniques used to do so. General carpentry question such as framing/decking/general construction might get a better response in /qtddtot/ or /sqt/.

>essential /wwg/ books

Tage Frid Teaches Woodworking, gives you everything you need and shows you how to do it multiple ways, from hand tools to power tools and gives you the knowledge to determine which is best, and then he teaches you how to apply what you learned. The PDF of the second book can be found in the usual places, but the other two are MIA.

I should mention, ALL WOOD ON THIS PROJECT IS PINE.

I then put the whole thing together with some bed hardware from amazon.
https://www.amazon.com/gp/product/B07GQRL7B8/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Then sealed it with water based polyurethane.


At that point it was time for the backboard which was painstaking no doubt.

The backboard is 6X4. measured everything out in sketchup and then printed out the primary pattern I was working with. I had bought wood that was 5/8 X 2.5" semi scrap from home depot. The wood was very rough cut, which was perfect. That was burned and brushed. All angles are 45 degree cuts. Some of it ended up being a little free form as I ran into issues. But generally I would just cut a few pieces up, fit them all together, glue and staple the most critical pieces first after measuring it all out. Then proceed to glue/tack it all down from there. It was a very pleasurable experience. Ad hoc at parts, but still very orderly. Getting everything to fit just right was challenging in a good way.

In the end I had very little waste, just a bucket full of 45 degree cut offs and 3 feet of remaining sho shugi ban'd wood that I was using for the parquet.

Sorry for the shitty picture. How would I go about making something like this? I can imagine how I would cut the vertical piece of wood but I'm not sure how I would mount it to the bottom piece. I need to make a few of these and make them look very good because they would be displayed in my locksmith shop with various hardware attached to them. For tools I have a few different saws (hand, table, circular), drill press, hole saws, and wood router with various bits.
I can buy the one pictured for ~$80 but that seems pretty steep for a couple of pieces of wood and maybe an hour of work.
>>
>>2269004
>I'm not sure how I would mount it to the bottom piece
Two screws, run in from the bottom.
>>
>>2269004
Cutting out a door for a lock chest requires quite a bit of skill or specialized jigs. If you cant figure out how to put two pieces of wood together you are better off just buying them.

Unless you really just want two holes. Then it should be ezpz.
>>
>>2269398
The slanting on the bottom piece will be tricky. You could use a router and a jig but trust me bro just give up and buy.

I'd recommend getting good tools. Generic micro-drivers deform and destroy things really easy.

Wiha ones are all made in Germany or Poland, and aren't too expensive for not being made with slave labor.

my master bath has an old outdated shower diverter knob like such. sorry for shitty picture just copying something off google.

It's leaking behind the wall. I unscrewed the handle under the index button but the knob won't pull off so I can access the cartridge/valve. I pulled pretty hard. What should I do now? Really don't feel like paying plumber $400 for what looks like an easy fix.

perhaps there is confusion. I want to swap my video receiver antennas while the quad is airborne. from my understanding, there is no power from the video receiver to the antenna (as it is just a receiver, not transmitter or tranceiver) so swapping antennas should be fine but radio waves are wacky and I'm too retarded to know if there's some funky shit that will screw my video receiver.

Not necessarily but taking the shot closer to a target provides more accurate information due to the relative temperature gradients.

Getting them from china can be much cheaper and they use the same thermal cores as the stupid addon cellphone sensor.

Everybody today is bitching about how expensive housing is. When new houses are built, that increases the supply of housing, which helps to reduce the price of houses. Econ 101.
People should be thanking craftsmen in general because they help cool down the housing market.

About Essential Craftsman specifically, sure, he's a boomer, but he built a new house. I've watched many of his videos, and he cares about doing good work. Not everyone is like that. There are too many people alive today who don't give a shit about quality, don't try their best, are lazy, scam others, and are just trying to see how much shit they can get away with.
Hats off to Essential Craftsman for giving a shit and producing educational videos to help the rest of us develop knowledge and skills.

Yes. And don't forget: having air ducts in your house is horrible for another reason: you have all these air ducts which collect dust and possibly mold and you have no idea what is in those air return vents.

On the other hand, forced air is great because it easily dehumidifies and circulates the air in every room of your house. Important in the summer time in warm/hot & humid areas.

based. "Architecture school" typically succeeds only in convincing ignorant children they know everything about housing and building and gives them a piece of paper which they use to inflict their stupidity upon the world of real estate.

I knew this one dumb cunt who was $140k in debt, not even finished with her architecture degree, was talking about how she was so much smarter than everyone else because she understood how walls create privacy and most people don't understand how walls block views of bedroom and bathrooms. She said her plan was to defect to the UK where she would not be legally obligated to pay back her student loans. I also remember her saying (about the UK) "there are cameras everywhere! nobody is doing any spying". Unironically. She had no qualms with big brother watching and tracker her every move. Thought it was quite natural in fact. God I hated her.
