Welcome to /diy/, a place to:

Post and discuss /diy/ projects, ask questions regarding /diy/ topics and exchange ideas and techniques.

Please keep in mind:
- This is a SFW board. No fleshlights or other sex toys.
- No weapons. That goes to /k/ - Weapons. The workmanship and techniques involved in creating objects which could be used as weapons or the portion of a weapons project that involves them (e.g., forging steel for a blade, machining for gunsmithing, what epoxy can I use to fix my bow) may be discussed in /diy/, but discussing weapon-specific techniques/designs or the actual use of weapons is disallowed. Things such as fixed blade knives or axes are considered tools, things such as swords, guns or explosives are considered weapons.
- No drugs or drug paraphernalia (See Global Rule 1). If you want to discuss something that could involve such things (e.g., carving a tobacco pipe from wood) that's fine, but make sure it's /diy/ related and doesn't involve drugs or it will result in deletion/ban.

Some friendly suggestions for posting:
- First ask Google, then ask /diy/. Your question will probably be better received if you do so.
- List available resources (tools, materials, budget, time, etc.)
- Try to use pictures and explain the goal, if possible
- Be patient, this is a slow board; your thread will be around for days.
- Share your results! /diy/ loves to see problems solved and projects completed!

Have any of you ever started a pirate FM station before in the United States? I really want to DJ some electronic music on a vacant FM channel next year. I've read it's a good idea to buy an expensive but well-made FM transmitter to avoid interference, and keep the FCC off my back longer.

I've got access to multiple rooftops around campus, so I could erect antennas remotely. It would really suck to have my equipment stolen/damaged/confiscated though.

It seems like so much fun, just screwing around on the airwaves and playing good electronic music. The FM radio in my state is such shit, it's all either cumulus or iheartmedia regurgitating the same top 40 garbage.

sup diy,

i recently got a cheap ass stove and the thing gets so fkin hot it melts the wire that is connected to it...

is there a diy way to protect wire from heat? i covered it with aluminum from a can but i guess that still conducts electricity so its as good as leaving the raw wire naked...

any ideas, besides buying the protecting sleeves?
>>
>>1514669
Just separate the wires so even if the insulation melts off they never touch.

Was driving through the state of missouri today and stopped to fill up. All the gas pumps have this fucking plastic sheath thing over the nozzle that needs to be depressed by pushing hard against the filler pipe. Is this just a missouri thing? Do other states have this?

It is mostly that people watch the meter trying to put in exactly what they have in cash or get a nice round number, they see it at the number they want and yank it out not realizing they still had they trigger squeezed in their fingers, gas goes everywhere and I had to go out with the kitty litter to absorb all the spilled gas. The cost of the gas is not much for any single spill, but add in the cost of the kitty litter and the time and it starts adding up. If it is a good sized spill beyond what a bag of kitty litter could handle, have to call 911, if 911 gets too many calls within a set amount of time for spilled gas they start sending bills to the owner, it really does add up.

Most people immediately let go of the handle when they see gas spraying out, but every now and then you got someone who just panicked and would not realize the reason the gas is coming out is because they were still squeezing the trigger, have to shut down the pumps and the station, call 911 and wait while all the business goes to the station across the street.

Stupid panicky people make the 'safteycucks' somewhat of a necessity.

I never saw a person spill gas either, then I worked at a gas station. When you are just there to fill up you are there for maybe 15minutes tops and see at best a dozen people, so a fraction of a percent of the number someone would see if they worked there for 8 hours a night 5 days a week.

Never met a single person from the UK that would say anything other than 'petrol', certainly not 'fuel' as you did, and I have spent a fair amount of time in the UK.
>>
Haven't seen these in Finland, but we do not have the "toggle" pumps either(on petrol pumps for consumers. Unsure about tanking stations for lorries). You need to pull the trigger and hold it down until you're done. Very hard to spill unless intentional.

Barren _plots_ in my county are worth more than that.

The house I live in is a 60-year-old Suburb Special, thoroughly ordinary by US metrics.

It's worth like seven hundred thousand fucking dollars, in a shitty (though not full-on ghetto) part of the city. The ONLY homes in that price range here are out in the middle of nowhere, mobile homes, projects, or a combination of the above. The current median price for a house in Orange County is $720,000. Beyond the fact that I don't like living in a population center in the first place, based on price alone there is no way in hell I'll be anywhere even near here if/when I move.

This is ignoring the radically increased cost of living, perhaps most notably, insurance. As an example, my mother recently moved to Idaho. She was paying like $60/month for bare minimum liability coverage on a 16-year-old car. I think she said she pays like $15/month where she is now. At a cursory glance, staple groceries were like 40% cheaper there, too. Admittedly, not totally sure what the job market's like, but, based on what my sister and cousin there make (neither have any special skills beyond being competent beyond a basic level), it's nowhere near what that sort discrepancy would suggest.

Realistically, right now? The only good solution for living in a coastal city without a good job is to leave the fucking coastal city.

>What do you use for shaping the handle and pins?
For rough shaping I used a grinder with a 60 grit flap wheel. From there I smooth it up with an aggressive file, before switching to progressively finer sandpaper.

I've made serrated bread knives in the past, but never really made the leap to an actual saw blade as there really wasn't anything I could feasibly do with one that was worth the time/money.
What I have thought about recently was making a hunters trousse with a small bone/horn saw on it for work in the field making whole animals into smaller bits of animal, so I'll keep that it mind. My original thought was just to do some serrations with a triangular diamond file and a fairly tight pitch of about 12-15 points per inch (think thats how they're measured) so its kind of like a hacksaw blade... a very classy hacksaw!

Finished up one of the N690 blades with a wire-wrap handle (304SS and Brass)
Not inordinately happy with the ability to polish N690, it does get 'fairly shiny' but not the true mirror finish I was thinking of.it getting, but that may just be down to what I've got to work with rather than the steel itself. For a little workhorse knife anyway it doesn't matter if its a mirror, some gronk will just bin it in a washtub and scratch it to shit!
What I was happy with though was the stain resistance, basically no rust even when abused to shit, swimming in all kinds of nasty crap in my workshop, left for a couple of days wet and abused and it simply just doesn't give a fuck.
It also gets scalpel sharp, like outrageously keen to the point you'll fillet yourself doing the arm hair test- doesn't hold it for ages like some other steels but it sharpens/re-hones very easily as well.

So, I'd call it a 'compromised success'
Some good points, an excellent point and a couple of not-great but ok points in there

Aren't you concerned about dirt getting between the wires ? It will be hard to clean. Also what is under the wire? Also isnt the knife too heavy with this wraping ?

On the other hand It realy looks cool and I think it will provide nice traction with the hand.
>>
>>1514639
Its a tiny bit heavier than a G10 handled, hidden tang knife: which is essentially what it is underneath the wire. Just some 5mm G10 shaped to suit and the wire run over the top of it, I also run a thin coat of epoxy, with black ink in it over the whole wrap and then clean off the excess with some light sanding, bit of wire-wheel on the grinder and then a polish. That sort of helps stop anything from sneaking down between the strands and makes sure nothings going to wander around.

Do have some fine titanium wire squirreled away I might use next time to knock a bit of the weight off, but its pretty bomb-proof for the most part and will have a fairly long service time. One of the few hand made knives that would survive a dishwasher trip... not that it should, but it could

Second to that would be an offset mortise a tenon with the tenon wedged, much easier to execute an almost as strong.

Draw boring the tenon instead of wedging may be better, or even making your own cut nails from one of the very hard woods like lignum vitate, hornbeam or osage orange and driving them through in place of the draw bored dowels.
