possibly. lots of windows have pic related in that area, except I couldn't find a pic that shows the little ribs on the part that goes in the groove that keep it from falling out.

If your sash does not have some sort of seal on the front edge where it seats below your interior sill then you might need something to stop air flow if it's all wood next to wood.

Hey /diy. I need som help. Im a blacksmith whose used coal and charcoal for many years. And im switching to propane for a more efficient smelting method. Problem is the pin hole for the gas to escape. Whats the correct drill bit to use? Ill have oxygen control. So i can get the ratios right. But i dont want too much propane. Ive heard 1/32, but i dont know it thats just common hearing because its conveinient. Is there a more efficient size? Thanks~

P.s. pic is my current setup.

>> No.1281412

>>1281406

I AM NOT AN EXPERT.

but. a few years ago I replaced the main burner in my propane (LPG) furnace. the old one had an orifice of about 0.093. (1/32 is 0.031, and keep in mind that area is proportional to the diameter squared).

the optimum orifice, I believe, is when the flame is mostly blue, and not yellow. Yellow means too much gas or not enough oxygen.

I reduced mine to 0.062 (1/16 drill bit) and the flame is nice and blue and looks to be the right size for the combustion chamber. This was 4 winters ago, and it has seemed fine since.

So, if 0.031 gives you a nice sized blue flame then it's fine in my amateur opinion. If you can go to a larger diameter and still have a blue flame you might get higher temperatures with similar efficiency.

And someone who knows will eventually tell us both what we need to know.

>> No.1281417

>>1281412

I should add that my furnace has a plate that says the orifice should be #41 which, if it's a drill size, is 0.096 and I measured the old orifice to be very close to that.

However, the plate also says the manifold pressure should be 11" W.C. which I think means 11 inches of water on a manometer.

So I made a manometer which you may already know is simply a U shaped tube of water with one end connected to the pipe leading to the burner. In my case the valve has a plug you remove and install a standard pipe fitting. The other end of the tube is open to atmospheric pressure, and the water will be pushed by the manifold pressure and the difference should be 11 inches for me. I could not get the pressure that high which is part of the reason I went to a smaller orifice, but the main reason as mentioned above was that the flame was rather yellow before.

Does manifold pressure matter to you? I don't know, but it's easy to rig up and test if you are the type who likes to do that sort of thing. Maybe some HVAC guy will tell us. Back when I was trying to burn my place down I asked on an HVAC forum but once they figured out that I was not licensed they banned me.

Basically I have a couple nice pieces of wood left and being the upcycling madman I want to make a folding desk for the occasional pyrography work or a guest table for lan parties.

However I'm kinda braindead today after last night's outing so I can't figure out a cool way to do the folding mechanism. I know there's a way to do it with just one additional piece connecting the table surface with the black piece. The surface piece is 6 cm thick and has a 4 cm deep hollowed out area underneath - the border is also 4 cm wide. I can sketchup the individual pieces in detail if that's of any help.

The green piece is a pair of prefab table legs that I already know how to do.

Pic related, it's the rough folding idea with a stabilizing aluminum U-piece that would rotate and snap onto a bolt or something.

P.S. some might consider this cringe tier making but right now i'm broke and I hate throwing away workable wood.

I'm the other guy with the folding table. I made it foldable to get more space.
In the end, despite the folding mechanism being really convenient, I never folded it up, because there was always something on the table I would have to put away first. The lack of rigidity was becoming a problem in some cases on the other hand. And designing the plans, assembling it, etc was quite some work compared to just a normal, sturdy table. Additionally, I had shelves below, which were hard to reach, and I could only access the table from 3 sides.

In my new apartment, I just took the same table plate and made it a sturdy work surface with 4 large legs and a skirt. And now I can also move it somewhere else, walk around it, etc.
I'm not thinking that a folding table is never the right solution, but you're often overestimating the usefulness of a folding mechanism compared to the seemingly miniscule disadvantages.

Awwright. I figured out what I'll do. Shit's gonna be neat.

It'll be a 3-piece quick-assembly table. I'll use heavy duty hooks from my old bed assembly for the surface<>sideface connection and a leg piece that will stick into the surface piece from below into a big, snug wooden groove.

This way I can make the surface slightly slanted towards the user area for enhanced comfort. And it should still be possible to add a small foldable shelf into the sideface for my pyrotool.

Alright DIY I guess I didn't need much help, just time.

I don't understand the kinks in the legs. Seems like an unnecessary point of weakness, unless the most you'll be doing on it is electronics/very light duty work.

2000 naked people in an unknown jungle, that sounds like a recipe for disaster. But let's be optimistic, let's say they make i the 1st few days. Let's say they find water and improvise a shelter.
What the fuck are they going to eat? It's 2000 fucking hungry mouths to feed, imagine the logistics of that. But let's say they somehow manage to kill a fucking large herbivore every couple of days so they get to eat.
Let's say they find a clean field and edible plants and roots and they start farming. Have you ever seen the outcome of an elephant herd getting into a farmed field? There's nothing left but elephant dung. They won't have the manpower to guard that field, they won't have the resources to fence it properly, it'll be an open buffet.

well, creating farmland isn't THAT hard, pioneers did it all across America with hand tools.

the real issue is landing in a region with the correct weather, flora, and fauna to allow the time travelers to survive off the land long enough to build shelter and tools augment their productivity.

yes, early pioneers to America had a strange habit of dying of starvation and disease. it's not fucking easy. but once you can establish a large calorie surplus, creating farmland is a breeze. at least for annual crops. the real issue is the centuries of selection required to breed grains and vegetables with large fruits. ever seen wild carrots and onions? they're tiny. the grass seed in your yard is tiny. imagine trying to harvest that shit to make bread.

It only seems to do it when I'm printing something with a small diameter like the legs of an animal or the chimney on the Benchy

The area it's printing becomes overheated and gummy/pliable, then sticks to the print head or gets dragged around.

My printer seems to "spazz out" halfway through prints. Pic related. It's a brand new monoprice mini. It seems to always happen at the same height and the extrufer will move to the bottom left of the fab surface and flip out. Help.

Increase cooling / install cooling fan, add more parts to the same print so the print head has to move elsewhere is all I can think of

Sup /diy/,

I just got this direct vent propane heater to install in an 8x16 shed I'm converting into a music studio. I'm connecting it to two 40 lb propane tanks outside of the shed, on a changeover regulator. The manual says I have to have this unit professionally installed or else the warranty is invalid.

LIMITED WARRANTY APPLICATION AND COVERAGE:

- 1 year coverage from defect and/or workmanship on all parts
- original owner: lifetime replacement coverage of the combustion chamber
- not covered: all labor costs

Do any of you have a direct vent heater, and did you install it yourself or did you hire a licensed contractor?

It's a direct vent heater. That means the waste gas is vented out the wall behind the heater.

sorry didn't read. gas and flue routing are really simple. make sure to pressure test the gas line. it's really simple. use your head.

Do I need a pressure test or can I just test for leaks with soap?

Does anyone know where I can get this Chroma/QAM demodulator/decoder chip or a cohesive schematic for one I can make.

Took some digging but I believe you're looking for a NTE705a. It decodes svideo's chroma signal and output B-Y and R-Y.

Here's another more complex but complete solution. The datasheet even has a schematic.

Bamboo splitting advice? I have a problem with some bamboo project. I wanted to try and make a small hydroponic resevoir for a PVC set up I already have. Just wanted to try bamboo to make it more aesthetic. I see a lot of people doing this on youtube, but when I try it, I get split bamboo. I get the bamboo pre-cured, so I'm going to try and get green bamboo and cure it myself through heating. However, even still, I am told this may not work.

Any bamboo workers out there can give me advice on how to prevent/reduce drastically the splitting of my bamboo?

Knock out the diaphragms maybe? If you're going to heat cure it you'll want to do this anyway to prevent pressure build up.

Since it's going to be outside and wet you should coat the bamboo in a UV resistant spar varnish if you want it to last.

>I have splitting occurring in both punctured diaphragm culms and non-punctured. Neither seems worse than the other.

I'll take a look at the Spar Varnish. Do you know a brand that is food safe off the top of your head? Just googled it and nothing immediately pops up. I know most finishes once cured are food safe, but what about for constant wetting and drying with hydroponic equipment?

When I have worked bamboo I always worked it green and just let it air dry, it dries quite well on its own and fairly quickly. Some bamboos are fairly fragile, the thinner walled light weight varieties that are often sold for garden stakes and the like are quite brittle once dry.

My guess would be you either have a poor quality bamboo or they are not well seasoned.
