Very light touch and dunk it in water all the time. It's almost impossible to not over heat the blade edge. Even if the knife isn't hot to the touch, the edge you're removing material from (and going to cut with) with be hot enough to anneal and get weak.

KORG 9V pwr supply.jpg

Hey guys, I'm looking to design a power supply that will give me a good + and - 5V output. Probably only about 1A at most would be required.

I'm thinking the easiest way to do this would be a linear supply with the appropriate voltage regulators clamped to a heat sink at the output. But, this design is rather boring and requires a large transformer.

I've never designed a switched mode power supply (like pic related) but I like the idea. They seem to be generally safer (?) due to the incorporation of an optoisolator.

I'm just wondering...

Given that you have to ask id imagine paying a handyman will work out a lot more financially viable than doing it yourself.

Buying quality tools to do a lot of jobs is costly. You have to consider how well and frequently are you going to do these jobs so the tools in effect 'pay for themselves'.

These (especially light duty electric ones) go on sale a lot. Just wait and eventually you'll get lucky. A light duty one is almost a good thing sometimes because it's a built-in idiot limiter (you won't etch a penis into your siding accidentally).

Im building a metal shed to store some gym equipment. It's nothing large, but it will be used daily.

I'm at the final stage of planning, I have a few questions though and would appreciate any help.

1. I'm going to buy a battery powered LED Lamp to light the shed, what should I consider when buying one of these? I want to mimic natural light, I don't want anything too bright or straining to the eyes.

Should I put up a little insulation? It's a metal shed so perhaps it will get too hot in the summer?
If sol what kind of insulation?...

It won't necessarily get hot in the summer but you'll probably find it will hold a lot of moisture during winter. Personally I'd insulate the roof lining if anything but that's if I were to bother.

As for lighting, battery powered or mains? If you have mains power I'd look for warm white LED lighting strips, the self adhesive ones. They're as good as anything.

If you mean like a pre-packaged battery solution then the best will be something from a tool company but most will be bright and cool white.
>>
>>1056663
Insulation is better than no insulation. Insulation foam panels is easy to put up. Finish the inside with plasterboard like any interior.

Lamp could be anything. Normal led bulbs on a usual fixture will work like any other rooms in any other houses. Just wire it to a battery. A shed is not much difference than a room in a house in terms of lighting.

First DIY project but I've run into an issue. The wood I bought (mostly 2x4) had a slight warp/twist to it. The headboard frame I've built has a slight wobble in it that I'd like to correct before continuing on.

How the fuck do you correct wood that I've already screwed together. Currently trying to weigh it down. If that doesn't work, I'll try to apply water + weight and let it dry.

Got a bench band saw super cheap, but it didn't come with anything else. Suggestions for making a fence, besides just clamping a piece of wood, or preferably angle iron, to it?

You're trying to over complicate things. If a piece of wood or angle iron works then use that.

If you make a mitre guage out of two pieces of wood fixed at right angles to each other and it works, then use than.

The type of bandsaw it is, won't be as accurate are you're hoping for anyway.

I just saw someone on youtube who made something like the op pic, with one end fixed and a toggle clamp on the other....that was pretty cool.

It will at least be better than trying to cut it by hand

I could see a miter gauge from 3 pieced of wood, a cheap school protractor, and a screw on handle of some kind working really well.

Long thin piece of wood for the slide. A piece of wood to hold the protractor and handle assembly. The last block of wood at 90 degrees standing as the pushing block, Attached to the last block. A bolt going through the guide, protractor block, and protractor. The handle screws down on the bolt clamping it all together.

Set up a static IP for your phone on your router then have your esp ping that every few seconds. If it can't ping you, you're not home.

This'd only work if your router is close enough to the entrance of your house to connect before you make it through the door.

Mansfield toilets: why don't they have "normal" flappers?

This design just seems, well, over designed. It's not difficult to replace (I just did so this morning) but it's more complex than just swapping out a flapper.

Lets more water out at the first opening, full 360, rather than with a regular flapper where it's peeled up slowly, starting with a trickle increasing until fully open.

Think of it as an early version of low flush toilets, by combining the low material contact, wear, and replacement with the original power of a flush ball or disk.

compare it to the newer lower flush kohlers with a bucket similar to that, but with more buoyancy to raise quicker, or the toto or american standard version with a ring around a plastic flapper that moves straight up on a guide like...

I think Mansfield style designs are the norm in Norway, and unless there's something wrong with the float assembly or clogs in the exhaust line somwhere, they never struggle to dismiss even the largest of dumps.

Has anyone tried to make a bismuth monocrystal ?
I'd like to make one during next holidays, but there is no website referencing how to get a single crystal.
What I did learn however was :
- Molten bismuth oxidizes quickly, so you have to keep a surface in contact with the air as small as possible
- You get a ~70% yield in crystal(s) because you have to pour the molten metal when the crystals have formed at the bottom.

Cool it as slowly as possible.
Use larger volume for bigger crystals (obvious)
Dont disturb it while it cools, vibrations cause small crystals to form.
Cover the crystals from oxygen when you pour the liquid off.
Use high purity bismuth, otherwise the crystals wont be colorful.

There is usually a thread dedicated to 3d printing, you would probably have more luck there. You probably want to replace the component that's been overheating and then modify it with a cooling device (just point a fan at it or something if you're not creative). It's also advised to research the bed, and the firmware you're trying to use to heat it, to make sure they actually play nice, and also make sure that the controller board is configured...

Thanks for the reply m8, the /3dpg/ thread is dead, already replied there to no response. yea the bed is reprap 12v bed, standard. I'm thinking maybe they cheaped out on my ramps board. It was a sainsmart from microcenter.

I donno sheet about 3D printing, but I doubt it.

I do have machine tools--and the kinds of poly-whatever thermoplastic that I have sawed, drilled or machined always come out real stringy.
They don't cut smoothly at all. Only Delrin or acetal does that.

Acetal vaper good works with 3D printed parts.

>>1055916
Absolutely not

3 MB,
My crank arm/set makes a noise whenever I apply my weight to it. Not sure if my bearings are bad or if the bracket holding the bearings needs to be tightened.

In any case I'm having trouble removing it. What tool can I use to remove it? I've used one of those cheap tools that come with the bottom bracket but it's just tearing up the groves.

if the spanner is tearing shit up you can use a hammer + chisel and tap each notch in the nut

you'll need a different spanner to get into the dimples.

do you have a tool to get the crank arms off, you'll need that to replace the bottom bracket

Also, keep in mind some parts are reversed threaded. You could be turning the wrong way.

238 KB,
$5 angle grinder. Probably goes without saying it's cheap. But if you dont abuse it i got one from there over 5 years ago and it still works like new. This is in store and u have to spend $50. But lets be real. Every one of us could use $50 worth of shit from there and a $5 grinder. http://images.harborfreight.com/cpi/emails/3716/b/images/AngleGrinder.jpg

AvE just did a teardown on these. They're not professional grade, but for occasional home use they seem to be a pretty good deal even at regular price. And shit, for five bucks? Why not?
>>
just use the normal coupon and get it for $12

>>1055814
That was the higher end model. This one is even crappier.

Well worth $5 though. I have one with a diamond wheel for sharpening tungsten.
