Recently made this flower press for a girl I've been seeing. she absolutely loved it and I'm really keen to start a few a few more projects we can do together. I own a machineshop so I'm not really limited in what I can make but I love using hand tools. Will make a drawing up of the flower press if anyone is keen on making one themselves.

I want to spray paint a plastic case, and I want to do it well. Problem is, I swear every time I paint with spray cans, it turns out horrible.
I know the basics (like numerous thin coats, not one large thick coat), but in the end, it still turns out like shit.
How the fuck do I paint using Rustoleum spray cans?

Here's the steps I have in my head of what I need to do. Somebody please fucking correct me if I'm doing it wrong.

This guy goes against the grain of what I always assumed to be the right way to do it.

1.) 1 thin coat, followed by 2 thick ass coats.

2.) Dry for 2+ days. This causes shrinkage and "orange-peeling"

3.) Spray on clear coat.

4.) Wait a few more days.

I definitely want to have a high-gloss result when I'm finished. Not just for the aesthetic quality, but to have a force field to protect the paint underneath.

So I assume it's:

1.) Sand object until it's a smooth, flat surface.
2.) Clean with soap and water, mineral spirits, anti-fungal cleaner to prevent mold from ever appearing under the layers of paint.
3.) Spray primer
4.) Wet sand in between primer coats (?)
5.) Wait for it dry.
6.) Wipe clean with soapy water, and wipe with tack cloth to rid any settling dust.

So I have 1/6 sheet sander like this.

Whenever I try to hold flat on the work piece, it keeps jumping around like crazy.
It vibrates at 12,000rpm and I feel like its way too much.

I don't want to push down too hard on it to keep it in place because I fear it will bog down the motor.

Lately I've been lifting off at the back and just having the front part of the paper in contact with the wood. But that is slowly wearing down the backing pad.

Am I using it wrong?

this is for light finish sanding... what are you trying to do with it? if your trying to remove a shitton of old paint, or smooth down extremely screwed up surfaces then this will probably not be enough... maybe look into a belt sander with some 80 grit..
I'm using it as a finishing sander. Tried it on a dozen things and had the same result.

Used it with 600 grit and water to reduce orange peel on a freshly varnished table top.

Used it dry with 320 grit to finish another coffee table before staining.

Even tried with 1500 and 2000 grit wet to color sand my truck.
Don't push down so hard? The weight of the tool is almost enough to do the work.

Or get some more strength in your arms. I haven't used one of those in years because I bought an orbital, but it doesn't jump around at all. If I push it hard enough that it binds and would jump, it just stalls because my arm is stronger than its little motor.

My main job duties involve 3D printing but thats not really the part I like, it's the design work (I'm studying mechanical engineering). If you are only going to be printing things, you will be extremely bored 90% of the time because you go through the process of setting up and starting the print, then you sit there and wait for it to be done. Unless you have 10+ printers, you won't stay busy.
Honestly, 3d printing is pretty boring when everything is working.

When things aren't working you have to figure out whats up and change it, but after you get things dialed in that's kinda rare.

When things are working you just click print and make sure the first layer goes down right and then check back in on it a couple hours later.
Thanks. I think I could live with that because I'd be doing the design work too and I figure I'd be able to justify a massively overspecced computer in the budget for 'designing at work' (his setup budget is 4 times the cost of the printer + a separate budget for filament) so I can also do some CGI on the side, which is a hobby of mine but is sometimes called upon for promotional videos (the last one landed me a 4K prosumer camcorder for production that was mine to keep by way of payment).

2. I like peace lilies, they do really well indoors and clean the air
Spider plants, philodendrans, mother-in-law tongue, parlor ivy, and parlor palms all do very well inside.

I have a philodendran my grandmother gave me when I got my first apartment. It started out as three 6 or 8 inch vines.

Twenty years later I have hundreds of feet of vines wrapping around my living room, kitchen, bedrooms, bathroom and basement.

Spring, summer, fall, winter my house is a stable level of humidity.

I've also noticed that the air quality is amazing. When I've painted, or stained anything in the kitchen the smell is gone much quicker in the house than if I do it in my garage. When i painted four years ago the paint smell was gone from the house days before the garage was clear.

My philos are awesome I water them about every other week and they thrive. The ones in the bathroom don't even have a pot. They're just loose vines hanging from hooks around the perimeter of the ceiling. They also grow the fastest from the skylight. The pot was cut away during a remodel and the vines were left in place to die. Still waiting six years on for that to happen.
Could you maybe post some pics?

Once a relay starts sticking, is it toast?
Maybe my problem isnt the relay at all

>microwave makes loud popping sound during cooking

>open door, everything stops, close door it starts back up by itself again.

In the repair manual it says that problem is caused by relay 2 not closing and to replace the control board.
I cant find a board to replace it if I want so im gonna try and fix it.

I unsoldered both relays, both normally open relays
Relay 2 works as it should when I bench test it
Relay 1 was stuck closed when I initially tested it with just multimeter. It also seemed like there was something loose jiggling inside.
When I put power to relay 1, it made kind of a weird noise, I checked and the poles were closed.
After I took away the power away, the poles opened up. It works perfectly now, bench testing it. It also isnt jiggling inside

The control board isnt burnt smelling. There are no obvious signs of heating, no obvious signs of a failed component.

Does that sound like a failed relay?
If I put this relay back in, will it just stick again?
It was a huge pain in the ass to get the board out. And I cant find anywhere but Aliexpress to get the relay, suck to wait 30 days for it.
Using transfer paper and a laser printer sounds a whole lot easier than that.

Does anyone here know about plumbing? I'm having a problem which is perplexing me. I'll try to explain it as best as I can.

My bathroom sink is giving off foul sewer gas but only for a few seconds when i run the water. I've come into the practice of stopping the sink with a rubber stopper before I turn on the faucet and then removing it after a couple seconds. I'm led to believe that when the water from the faucet shoots straight down the drain it creates a turbulence that allows gas to escape, and when I stop the sink and let it fill a little bit...

Sounds like your sink plumbing vent it is blocked. It happens. The P-trap in your drain is preventing the gas from getting into your bathroom (good) but the gas is unable to vent because the vent is plugged (bad). When you run the water gas sneaks in past the P-trap. Running a snake from the roof down the vent stack can clear it, but it can be tricky if its not a strait shot.
My gut told me to say check your vent as I was reading, and then I got to the part where you said you'd heard a vent can cause this. So have you checked the vent? Also, how many drains use this vent and what diameter is it? It's possible the plumber installed one that is too small.

I live in a condo, so am not able to do it. I did ask the people who live below me if they had the same problem and they said no. But they probably didn't have a clue what I was talking about.

I can ask the manager if he knows of any issues with the buildings.

Hey /diy/, first time doing plumbing here. Tail pipe got torn from the sink and when I went to remove the s-trap the slip nut also broke. Any advice for attaching a new pipe to this part? I'd have to cut the pipe if I was going to pull it out because it goes down so far inside of the other pipe. Alternatively I was wondering whether it would be wise to use some sort of hose clamp coupler here instead of removing it. Any advice is appreciated.

Now most of the info I find online is either branded or really vague. Is there no good radio based video systems? The idea of app based systems really looks appealing because I can just buy cheap tables and put them all over this house provided I have a good enough wifi signal, the house itself is big and that would be realy handy because many of the areas where one spends time are very far apart, but after such a shitty app that keeps crashing and requires you to set up again I'm concerned of that side of the product.

Well given this is a diy board, why don't you look for a wireless ip camera that has IO ports and rig your own doorbell. Most Axis cameras have onboard IO, two-way audio and a fairly decent api.
depends what you actually want, there is a number of systems where the doorbell acts like a IP phone (you can run a DIY PBX out of an old PC) and the camera is ONVIF capable, so you can connect it to a surveilance system.

But they aren't exactly cheap and quality does scale with price. Really neat though, the doorbell dials a phone, if nobody picks up, it can dial a different one and the ONVIF camera means it's easy to have it record onto a server.
This would actually be ideal, was my first idea, probably cheaper and actually be more of a learning experience than most of the stuff I could buy. But sadly, and even though I know this is the diy board, an actual diy solution does not fly well with the owner of the house. And he insists in buying an out the box system.

Does pvc sink in concrete?
Laborers form it after they pour the general shape of the concrete. Make sure your forms can hold and try not to fuck up.
No. As concrete sinks and tries to level it will lift the PVC unless it is also filled.

Why cut pipe in half? Buy a length of PVC guttering and use that. Dig your trench, drop the pvc in and pour concrete in around it. You will have to span timber over it to stop it from lifting. Make sure you use a relatively wet mix to fill all voids.

In all honesty, probably not. Best suggestion would be to heat it up closer to the melting temperature of the glass (another ~300-400ºC beyond the melting point of aluminum) and see what happens. If you try, please post results (I'm curious now).

what can wet glass to aluminum?

...the difference in thermal expansion rates can't be good tho
You want more molten glass and less aluminium, I've seen glassware which had some sort of artsy alu inclusions put into it, but the difference in melting points probably makes this fairly difficult to do.

>put water in motor
you have to be 300% retarded to do this
but it's easy fix, just take it apart and clean off the oxidised areas and re oil it
for future reference, a $30 steamer machine works better
Why didn't you use a hair dryer?

Ramp thread.

>Are there any ways to get materials cheaply?
I've thought about going to a construction site at like 3am and taking some of the wood they leave laying around. But that's obscenely shady and I'm not certain the potential repercussions would be worth the potential benefits.

>How to warp wood to align to a curved ramp frame?
I've heard of people using pools, dipping plywood in the water and bending them but this sounds horribly inexact and I want a quality product...

Yeah that's what I was getting at.
Go to a construction site, where they dig water pipes, heating or sewers. Ask for the manager, and then ask for used materials.

They often use plywood to prevent soil from collapsing down in to the trench. Some plates might be scrapped even though they are fine.. I have salvaged 20 plates this way, often in 244x122cm

Otherwise ask where they mold concrete.

I making the plans for renovating a bus to live in and I'm thinking of converting the engine to run on compressed Bio gas so I can use my shit and wasted food as fuel. Was wondering if anyone knew anything about the conflicts and safety hazards of installing an anaerobic digestion chamber in place of a septic tank. Also, advice on converting internal combustion engines would be great.

I already know about the compression process and the need for filtering for sulfates, CO2 and particle matter. I more so need to know about dilemmas involved in trying to fit the chamber under the floor and the possible efficiency drawbacks in the size limits
If you want enough gas to cook some food yes but run the engine nope. You would need a lot more shit for that than one person can produce.
do you know of any sources that elaborate on the ratios of waste to produced methane? I'd rather not test this myself

I'll be starting an apprenticeship in a couple weeks with a local union. I hear this is terrible idea due to no work and monthly union dues.
How'd you learn it?

I didn't/haven't learned carpentry but at the construction company I work for they send you to night school for 10 months or some shit to become a carpenter apprentice. Not really sure how the field guys work their way up from apprentice to carpenter foremen though. I think it's the smarts, people skills, and computer skills which separates them from the rest. The carpenter guys that work for the concrete department here generally build the formwork.

I'm just a couple years into the industry...

I foolishly quit my job.Then, when it got time for me to find a new one my friend told me to just work with him as a laborer for a framing company.

It was that easy.No interview, nothing, just ok, you want a job, well here you go.
If you just wanna learn framing carpentry. it'll probably be a waste of time and money joining a union.

Honestly I'd look around your area and try to find builders that survived the last housing recession. (If you wanna do residential). These are the people that have smarts about them and usually won't lay you off in 3 years cause work dried up and they ended up spending their nest egg.

I became a finish carpenter with no prior experience. I just happened upon it after losing my previous...
