I make charcoal for pyrotechnics and home forge use. A kettle grill will work but it will limit the volume that you can do per batch. The standard small scale method is to use a paint can with a few holes as a retort. If you want to use multiple trees, I'd look into getting an old 50 gallon steel barrel for your retort. Otherwise, the old method of using earthen pits and covers and such is more suited to large scale operations. Retort cooking affords the user better control over the conversion.

Another possibility is the TLUD (top lit updraft) method, whereby the wood being converted is also the fuel supply. This method is much more efficient in terms of fuel use, but yields a potentially inferior product. However, it is used by many with great success.

You can make an above ground coal "pit".

It just requires some stakes (could be green lumber) and box all the dry logs and wood in with green palm fronds, banana leaves or elephant caladium. They need to be fresh cut and packed densely or the whole thing will blaze.

Here's the one side with the screw undamaged.

Exactly what is the screw?
Bolt, machine screw, tapper etc. Post a picture of the one you got out.
If its any kind of cross head screw I would get a right handed (is that right? The opposite to normal) drill bit that's slightly smaller than the minor diameter (the troughs or valleys of the thread) and drill it out. Use the middle of the cross head to centre it and go slow. As it drills out it will loosen and hopefully catch and just unscrew. Otherwise then its a good start for an easy out screw remover.

Obviously replace with a better quality screw. Really you should do this with anything outside (or inside!) if you doubt the quality.

The reason you get two images is because there are two layers reflecting the image.
A mirror is some reflective surface like silver or aluminium maybe I don't know I'm not a chemist but if it was left out in the air it would oxidize which is just rusting basically except rust is only things with iron in like steel. Oxidised silver isn't reflective so its a shit mirror.
So what happens is they put glass in a vacuum chamber and microwave a block of silver so it turns into a gas and sticks to the glass. Because the glass stops the air getting to the silver it stays shiny.

A thinner mirror will make the images closer together but won't get rid of them exactly, I'm not sure about plastic mirrors but I think maybe of you can get a material that is the same refractive index as air it might work? I think? Fuck.

But what you can do is get a 'mirror' where the back side is used and instead of silver it's coated with something that doesn't tarnish so stays shiny, but you buy them from science shops and they are expensive and sometimes a funny colour.

You need a first surface mirror. IE the reflection doesn't go through the glass. There are first surface mirrors in old laser printers, scanners, copiers, etc

>>1220797
Gah...

What you are looking for is called a first-surface mirror.
The reflection/refraction/ you are getting is 1) from the glass surface and 2) from the mirrored surface behind the glass.
First surface mirrors are hard to find and really easy to scratch. Might check an old overhead projector or scrapped projection TV.

If you think about how a drill works the thickness of the material isn't a particularly important factor, it doesn't go through all at once.
The power required is a function of the speed the drill rotates at (depends on material) and the size of the chip being removed. If you think about a drill bit rotating a larger bit is traveling faster at the edge than a smaller bit at the same rpm so straight away we can say that a bigger hole requires a more powerful drill, but also the size of the hole means a larger chip, more material being removed per revolution so more power required however! You can mitigate this by starting with a small pilot hole and gradually working your way up slowly you can get away with much lower power requirement.
So, it kinda depends. But 1/4, 1/3 hp is pretty typical I think for a bench drill?

>>1220608
Thanks for the insight. I really don't know too much about this sort of thing.

There are some local sellers selling their used machines and many have a 1/4 or 1/3 motor. It seems that a lot of the 1/4 motors get 1750 rpm. That enough for metal?

Here's a quick sketch of kinda what I'd imagined, ports would obviously have to be on the back of the case.
I'd probably also get a few hinge joints so it can be opened, and maybe some sliding doors to cover the ports later but this is it so far

>My main question is: should I sand&finish the undersides and the sides that will never be visible? Does it make a difference to how well the wood handles time? I should probably assemble it first, only then sand and apply the finish, right?

You should always backprime the hidden surfaces to keep the wood from dry rotting from the inside out.

Where might one acquire large walnut panels like that?

>>1220725
I assume you're just asking generally and not where I plan to get them, but just in case I'd be fine with 250mm wide. I'm sure there's boards that size.

>>1220243
It'll reach this one and the one farthest back.

The red tubing is what we used to make a ring along the inside of each box with pin sized holes about 3-4 inches apart all around. On this first one the pressure is great and water flows 5-6 inches from each hole.
> Pic too big I'll upload at home
The PVC pipe is half inch and plant box is 8 by 3 feet

I'm thinking we're missing something because the pump is connected directly to the outside faucet and then the PVC hose to the pump. We've never done this before and I know the pump isn't meant for this. I'm thinking it's either pressure, pump, or missing part related. The missing part being some kind of regulator or reserve tank.

>Any knowledge from /diy/?
looks like a drill. this one looks a bit heavy and cumbersome to hold so probably put it on a table or 'bench' (technical term for table).
if you plug it in the bit at the front should spin around. pull on the handles to make the spinning bit go up and down.
used for making holes, the bit at the very bottom of the spinner can be swapped to make different sized holes but you need a special key.

Personally, I add a tablespoon of baking soda every week, sift it around and let it sit overnight, then dump it. Also, a light dusting of Gold Bond will help.

Another friend of mine keeps a dryer sheet in his when he's not run in to absorb the smell.

Last thing would be odor absorbing insoles, but those are terrible for ergonomics.

UV light or ozone on the inside

Wash yo feet mohr, and do it right (SOAP and SCRUB every last millimeter of your feet before putting on AND after taking off shoes, making sure they're 100% dry before putting on fresh socks). Change socks every day (if yo feet sweat a lot, change socks 2-3x a day depending on how long you gonna be working). Also, do not wear the same pair of shoes every day, have 2-3 pairs to switch between every day so yo foot sweat and bacteria don't build up to make them bitches stank.

Aside from that, try any of the following:

Black tea bags (specifically) inside the shoes.
Baking soda inside the shoes
Kitty litter inside the shoes
Baby powder inside the shoes
Use a spray bottle of rubbing alcohol to spritz inside the shoes

Let that shit set in the shoes for a few days or until the stank subsides.

use a oxy-acet cutting torch on full blast directly aimed at your sample with your graphite crucible

or use propane and a better refractory

ummm, no.
Look into arc furnaces, nothing else that's DIY-able has any chance of melting tungsten.

>large acetylene burner

seriously though - don't do this shit, any malfunction and the oxy/acetylene mix will turn your furnace into a bomb.

Also - graphite crucibles oxidise very rapidly in an oxy/acetylene flame, they won't last long.

I hope you mean 'chop saw', or 'mitre saw'. not circular saw...just my first point...
cut up 4 or 6 pieces of the material your using for your base...cut 2 with 45 outside and inside mitres...the other 4, cut them at 44 and 46 inside and outside mitres, so that what you get to either an inside or outside corner, you can now see what will help in keeping your mitres closed...
As an alternative, you can also cope the joint...

i meant circular saw, only tool i got i work with that. It has a very nice guide for making 45° cuts but it cant go beyond that.

would sanding the edges be unrealistic?
i insisit on this because its the only tool i can easily borrow and dont have to buy

also what tools do i need to cope the joint

>>1218994
A coping saw. Or a jigsaw if you have talent.

Seriously though get a miter saw.

And invest in some wood filler and sand paper.

Perhaps you could engage the castor's locking mechanism? The thing that is designed to do exactly what you're asking?

Replace the wheel if the lock doesn't work, don't be a nigger.

What're you upto?

Causing trouble?

Get some thermite place a cast iron engine block on it and melt the engine block to it.
