I forgot to mention! I will definitely try any recommendations, and would be more than happy to bring back any results, with pictures of test tiles, notes etc

I've seen paperclay which is pretty cool.

What would happen if you included iron filings or something like that?

Wat?

You're trying to make a hand crank forge blower?

Hand crank, gearbox, and a squirrel cage blower fan...

Or, just go to the junkyard and pull any blower motor assembly out of a dashboard and power it with 12 VDC. You'll be able to move plenty of air with one of those

trying to keep it around the house stuff for now untill i start my new job. but i have heard the good in it.

>>970807
it's like $2.50 a can at walmart

the busted ass controller must have had some system to switch the load, see how they did it.
then again that might have been why it failed.

if its higher power try contactors but it might actually be more expensive

>>970759
What about a solid state relay? A 100A SSR from China can be found on the internets for ~$15 cdn, and should be big enough to withstand the inrush current. Full disclosure: I don't really know what I'm talking about.

>>970782
Solid state is good for rapid switching, not so good for continuous load unless you way oversize the motherfucker.

>>970759
A: look at the motherfucking unit
B: find the continuous amp rating on the motor
C: Go to Home Depot, get a thermal circuit breaker rated to what you found in step B
D: wire the line lead to the breaker and the neutral straight to the motor

This gives you over current protection (a must if you're fucking around with mains power) and an easy way to turn the motherfucker on without melting an outlet.

Mix it with your gas. Also run the mower until it runs out of fuel.

>>970748
Youprobably hae some gunk and water (from condensation) in the fuel tank. Before you fit the filter, disconnect the fuel line and let the tank drain completely, toss away the waste gasoline (or use it for bbq starter) and fill it up with 90%gas and 10% ethanol. That shoul clean most of the shit out.

Also; since you wrote that you already cleaned out the carburettor twice, I'm assuming you already checked all valves, et c. If you didn't, et an air compressor and start working. Inside and outside.

>>970748
Not to insult your intelligence but I'd consult your owner's manual. Simple machines and engines can have really finicky requirements most of the time. If you're not adding enough engine oil, or the wrong grade, or too much, or you're not doing the choke right, or you're priming it wrong with a return line valve that should be open when it needs to be closed, ect. A lot of shade-tree mechanics will overlook shit like that.

Without ever having meeting you or seen your shitty lawnmower I'm guessing it's the fuel mix.

Those goofy snake-oil fuel cleaner things might be a 4th option, after everything else has failed.

I would just buy a used guitar which is what I did. With musical instruments, especially guitars, buy one, learn to play a few chords, learn 'Smoke on the Water' get bored with it and either let it sit collecting dust or they sell it. Most used instruments are barely-used and relatively cheap. I dunno if there is some weird tax on guitars where you live but a used, basic Squier Strat should'nt cost much more that 200-400 euros. I bought my in Alaska used at a music store for $170 and it included an amp.

If a kit is incomplete don't be surprised if the cost of the piece that's missing doesn't sum up to be about what you'd have paid if some guy in China assembled it for you.

>>970734
"Recently got interested in customizing and making guitar myself."

>>970743
Sorry I tend to skip the first few sentences of whatever I read.

That being said, I don't know why you'd try to assemble a custom electric guitar with the cheapest possible parts from some made-in-china kit from online unless you just want a cheap guitar.

Just get a good guitar that's used.

Please learn English, I'll try to help you the best I can, try running a snake down the pipe and pour CLR in it at the same time.

>>970674
I will give a try. Thanks for the advice

>>970677
Also, when you are done, be sure to let the water run for like 5 minutes to get the CLR out of the pipes.

>Hi guys I have a piece of garbage, what can i do with it? btw no tools, ideas, or desires

Give it back to the vendor you got it from or place it in the trash.

>>970572
Use a new, sharp bit, preferably brad point. Use jigs/channels to line up the bit. Check your setup and accuracy about eight times. Advance fairly slowly, clearing chips often. Pray.

You are approaching this all wrong. Your only hope is to start with a small diameter pilot hole. Unless the grain is perfectly straight, drilling won't work and even if the grain is straight, drilling is a 5% chance. I make tomahawks and the pipe ones have the haft holed for smoking. The only thing that works is to use a small diameter steel rod heated to cherry red and plunged through the center. It's slow go, an inch or so at a time but it will allow you to stay true and centered. Once you have the pilot hole, you can use slightly larger diameter drills to enlarge the hole as big as you need.

depending on the size of the piece, consider turning the piece and keeping the drill still. That way it centers itself. Only possible if your piece fits into your chuck though.

But it's likely a mechanical switch

Op here, no need for primer then?

>>970497
uhh, you need a university degree for that. it's an associate engineering degree at the least. there is more to surveying than just putting down a theodolite. you need to understand geology and trigonometry.

>>970499
okay thanks. makes sense really. didnt know you needed an eng degree though. thats what im studying at the moment and thought i might be able to pull some small surveying role at the same time (i think i'd understand the geol and trig).

but just looking up qualifications and it says to become a registered surveyor takes 2 years practical experience.. by that time i'll have the eng degree anyway.

and i'm guessing that no one wouldn't take on any unregistereds

>>970502
no one would*

Also the metal seemed to be getting contaminated as fuck by all the charcoal ash floating around. How do I deal with that?

>>970412
I think the problem with this type of forge is that most of your heat is blown out with the jet of air. You need an insulated lid with a little hole in the centre.

I think you would have better luck with a graphite arc or resistance furnace.

>>970419
Alright, thanks for the advice, I'll try making a lid first as its the least work and if not I'll look into those other things.

How much money would they take to put together. Trying to be as cheap about this as I can.

When did /diy/ allow images over 5000x5000? Why wasn't I notified. This is life altering.

What? No dragon dildos? Fucking kiddo.

Best you could do is a spring loaded magazine at the bottom and a stopper on the top to keep the bolts from just flying out. Probably less accurate.

Trying to improve on the manual cranking isn't going to happen. You don't just pull the string backwards. You are transferring energy from your muscles to the crossbow limbs.

And these repeating crossbows were quite weak compared to "real" ones, otherwise it would have been unusable.

If you want to improve on it while keeping it a crossbow, add some pneumatics.

>>970290
Yeah a lever-action crossbow would involve your feet and you leaning most of your body-weight on it to cock it.

Otherwise, a stiff lever pulling back a string would have about as much energy as you throwing a brick.

If you need a gun, OP, just go buy a gun.

well what you have in your picture is a "Chu-ko-nu"

it fires an arrow in one motion by using the arrow magazine to draw the string, pre-knocking the bolt

they were made to fire a voley of tiny arrows very quickly, and were used en-masse by relatively untrained archers to hinder an enemies pike formations

they were neither accurate or powerful, because the draw is relying on a single action lever fired from the upright position
you COULD make a powerful version, but that would lower your rate of fire and at that point the whole design looses effectiveness

you could make a pump action version easily by loosing the lever and attaching the magazine to a slide, but it would be even weaker because it would be a bad position to draw with bow arm from
https://www.youtube.com/watch?v=zEuIwpYv3P0 (terrible video, but good design for a toy bow)

you could also hinge the lever under the bow instead of on top, but physics dictates the length of the lever is proportional to the ease with which you can apply force to it

I think some kid made one here that is probably close to what you want
