Gives me some good ideas. Thanks.
Hey guys, I'm thinking of casting a beer mug with aluminum.
I already have a furnace and aluminum, but I'm trying to figure out the casting method.
So far, I have a card board sleeve over a pringles container, and a handle carved out of styro foam.
I'm also thinking about wrapping the sleeve with layers of paper to make a pattern like pic related.
Feel free to post other castings for examples or for shits
Why not pewter?
>>899022
I don't have access to much pewter
>>898980
Update, I'll have the pringles on the outside and have a few coke cans inside stuffed with sand.
the aluminum will fill the blank space between.
After, I'll make a separate cast of the handle and place the body on top of it, the heat will join the aluminum where they touch.
Hi diy!
I'm kinda new on this board.
For introduction here is my latest project, I call it NEO. It was made from an Acer laptop, the best CPU temperature was 40C at the summer.
Sadly I poured one glass of water on to it, and it caused instant death :(
Btw how do you like it?

G'job OP
Are strap wrenches useful?
Im an apprentice plumber and my teacher says they dont work cause they never grip but he has the ridgid brand strap wrench with a cloth like strap.
It seems to me like a rubber strap wrench would be immensely useful. I hate the thought of putting a tool with teeth on faucet trim that has no flat surfaces for a crescent-like wrench or is too frozen to be hand loosed. Also i would imagine it could be useful for gluing larger sizes of plastic pipe. If youve ever tried to push schedule 80 pipe and fittings together of a large diameter you know what...

they're absolutely shit for anything more then hand tightened fittings. if a fitting is smooth as you say, it will be even worse. we're instructed to remove pump impellers off motors with them in my line of work, and never has it worked. strap wrenches are the result of an engineer saying 'hey, this should work,' testing it in a perfect setting, with all new fittings.
Strap wrenches can be very useful. I use them in my line of work and although I'm not a plumber, they work very well for certain things at my job. I work with instruments and equipment used in subsea surveying (ROVs etc) and when I need to bust open the endcaps of some equipment I just apply some heat and go to town with a strap wrench.
Tl;Dr yes, I find them useful

>Im an apprentice plumber and my teacher says they dont work cause they never grip but he has the ridgid brand strap wrench with a cloth like strap.
If you need to tighten something not-very-tight, and if it is too big to grab with your hand, strap wrenches (with decent straps) can be helpful. But they're not high-torque items.
A strap wrench is a girly version of a chain wrench--pic related.
(I am not a plumber but anyway) I would recommend that you also get a chain wrench--either...

I'm having trouble at work with Engineers 'improving' things while making them worse.
I'm just a grunt so they don't really think we know what we're doing.
Talking does nothing. I want to write some sort of proposal document that will be taken seriously, with a list of the problems, and how to feasibly(financially/time) fix them.
Is there some sort of generic Engineering proposal(Purpose, Scope, Cost etc) template to follow?
Anyone else have any experience trying to /diy/ at work and improving things? I figure this is...

I'll jut tell you my experience as a process operator at my plant. They do not care what you think and they think you're just trying to get out of doing your job. They will tell you to just try it out and no matter what they say they will not change it.
>>898151
If you decide to make said document, do not, in any case, hand it over to the engineers. as >>898164 said, they don't give a shit. Tell the people above them who care about the money where they could save. You might want to read up on some papers about kaizen and continuous improvement, maybe even six sigma. Refer to those and the managers will get instant boners. (Source: college student with engineering bachelor and business master.)
>>898167
And by the way, some context of your company might help. In the end the problem and its solution lie in politics, not in how bad the actual problems are or how genious your solution to them is.
Can we do a Homeowner General? I just thought I'd like to hear from other homeowners and different projects they're tackling or successfully completed. We just bought a house at the top of our budget. It's got all the space we need, upgraded kitchen's baths, and well-maintained throughout, but it's got some minor electrical issues, and it's going to need a new roof in 5-7 years absolute tops. Neither of us had parents who were homeowners, so we're not very handy.
Post stats on your house, projects, etc.

Just bought a small home in California, LA area. Needs to have the floors jacked up, foundation retrofitted, landscaping, painting, kitchen update, bathroom update, windows restored (wood), new electrical box, cat6 installed, interior exterior painted etc.. I have a bigass list.
Quite a bit of work for a first time home I have very little experience with this.
So far I have had the floors jacked up, foundation retrofitted and the stucco repaired professionally.
Getting quotes for bath and kitchen this week (they are pretty small spaces).

This is all very interesting and inspiring! I am also in LA county, but I'm in Pomona, so you couldn't really call it "LA Area" Our list isn't that serious, but it's still daunting. We have a hand full of useless light switches and ceiling fans that don't work. We had an electrician come out and he told us that it would be about a thousand dollars for him to install a motion light (which we've already purchased) over our garage. I wanted an outlet on the back porch, and the the...

tbf if they found that sharpened stick in a box with a whole bunch of knives and shit, or it was hidden under someones bed, they would be right to call it a weapon.
And for all we know, the picture crops out a whole bunch of other weapons they found on the scene, and the post isnt only about the stick.

Does being around black guys make me a black guy? I'm scared.
Any Carpenters here?
I'm planning to get into the coffin making business, you see, I rent a warehouse to a bunch of carpenters who make pallets and they say they'd like to make coffins but they need some kind of expensive, special, cutting machine so I'm considering on providing it if the business is lucrative enough.
So, is a special cutting machine it really necessary to make coffins or can you make them with with basic power tools?
Also, what general advise would you give to someone who is thinking on getting into carpentry?
>>897078
maybe they want a CNC router for embellishments
CNC router would run about $20k, maybe more. You might want to look into regulations surrounding coffins/caskets in your area. I don't know if hermetic seals are a requirement everywhere, but in some locations it is. Don't want corpse juice leaching into the groundwater, do we?

Btw, that wetness in the pic in my OP is just WD-40. I've had the head off for a bit now, and I wanted to insulate against moisture. Here's a bit of moldy interior for anyone interested.

Okay. Does that mean I can rob parts from my old mower? I have one lying around. It's a '97
I need to be able to interfere with or jam a certain FM radio signal within a few meters from my place.
Anyone got good information on a DIY jammer device?
And don't worry about legality, that's my problem.
Just broadcast noise in that range with more power than the signal you want to block.
1. build FM transmitter
2. pump power into it
3. ????
4. FCC

I'm dealing with a concrete ceiling. What sort of power would I need to disrupt a popular radio station in the unit above me? This is in a city, but not in the US, so don't worry about any FCC.

I was thinking of getting like a 0.5 W transmitter and rigging up a dipole antenna, but I don't want to spend $100 only to find out it has a range of a few feet LOS.
Anyone up for a workstations thread?

Don't forget to connect your ESD mat.

Im trying to make a home made electrolysis rig that I can use to split water into H2 and O2, and then direct the two gases into separate balloons for storage. The whole rig will be a closed system, thus allowing it to pressurize itself enough to inflate the balloons. I already have a pretty good idea of the design and how Im going to build it, with one exception. I cannot for the life of me figure out what to use for the electrodes. From past experience, I have determined that it must be both conductive (obviously) and also completely non-reactive. If copper, aluminum, steel,...

Good luck, OP.
>>895285
that is why it is sealed. so the increase in total pressure keeps that from happening.

I'm an idiot though so I have no idea what sort of vice will fit the damn thing.
it sits very sexily and glares at me for using 2"X4"s and clamps in lieu of a proper vice.
what reasonably priced vice can I get for it?

You can use any sort of machinist vise. I'd get a 6-inch angle-lock Kurt style. Also you could just use a hold-down kit.
That thing isn't really for machining though.
