drill a hole in the very center, stick a toothpick in it, tie a string around it and attach the other end to a glass knife, score the glass in a circle. I don't know if this will knock out easily, but you can always get a very small diamond drill bit and cut small holes all the way around the circle, then try to pop it out. Then you can sand the edge smooth. Sounds like a lot of work though.
>>920642 This is a great idea, thank you. And it took forever to find that 2-1/2 inch drill bit on amazon, but I did find it. I think I'll take the expensive and easy route instead of the cheap-but-hard route and buy the bit, lol
I would like to make myself a small lift to lift my computer tower from underneath the window to in a direct line out the window.
My plan is to just have the actuator mounted on top of a box that's on wheels that is just small enough to hold the tower underneath the desk when not in use. The actuator will be fixed to the top of the box and a plate on the other end for the tower to sit on.
Do I need something to stabilize the platform seeing as the only thing holding it will be the single actuator shaft?

>>920617 >Do I need something to stabilize the platform seeing as the only thing holding it will be the single actuator shaft? From the ones I've handled, yes. You would need some kind of rack arrangement that would move up and down, and then the actuator just does the lifting. >I am also having trouble finding how loud these things run, is the motor constantly running while under load or just while lifting? loudness depends. The motors only run when they... Comment too long. Click here to view the full text.
>>920617 These things are just a geared down DC motor that drives a worm drive that extends and retracts a rack unit. They also have a limit or reed switch at each end of it's stroke to disconnect the supply to the motor. Also bear in mind that you reverse the direction by the polarity of the DC voltage applied to the motor.
Hey guys I have a sickness and the only cure is more anvils ringing. Post pics of current projects you may be working on, favorite tools, techniques you just learned, inspire others to make something great. That being said, I'm currently a newbie and I'm thinking way ahead, I'm really not sure what anvil to get. Refflinghaus, peddinghaus-ridgid, Turkish/Czech anvils, cast steel Nimba, or the relatively new cast steel Blu anvils.
>>920608 Lokomo. I don't know where you live but here on the old continent old Soviet states have good blacksmithing shit. There is still lots of stuff available as it wasn't that long ago they were used. Aren't as expensive. I bought an eastern block anvil for my friend who is a blacksmith. Was cheaper and as good as a lokomo....
>>920603 Bomb proof home backup system? You probably use 5kw/day at most and assuming I lowball the batteries (50 usable batteries * 70 Ah * 12 V * .80 % efficency) you'd have around 35 kw of energy to use and I'm really lowballing this. You could use the rest to make a kickass car or a really strong welding setup. I'd talk to someone who does home backup/solar stuff.
>>920601 I'd use it as part of an off the grid electrical system for my house (48v 1283.7aH in series-parallel ), until they died in around the 5 year old mark.
How old are they? They might be worth more just as scrap. If so you can make a DC stick welder out of them or a furnace. Make an electrical car or a few electrical gokarts. They'd be great for one of those solar-powered Elf vehicles/bicycle hybrid things. There's lots of plans online for similar vehicles.
Everyone wants to go off the grid with solar panels and such. But how viable would it be to make your own little coal powered electrical plant in your back yard? Its a simple process, and I live in the middle of nowhere and have access to coal. Thoughts?
>>920582 High-pressure boilers of a size practical for your application are not Amateur Night projects; they're dangerous as fuck and could explode with the force a a thousand suns if not maintained and managed very carefully. Might also involve a permit/license.
Like another anon said it might not be cost effective or easy to source coal. Might be better with a sterling engine that will run off any kind of fuel. Bio, wood, coal, charcoal etc. Probably not very efficient though.
Could always pull out a diesel engine from a car or truck and repurpose it as a diesel generator.
>>920550 Can you explain? Is it possible to somehow link two displays together like a dual display monitor setup for PC, and offset the main signal enough to one side so that half is displayed on each? Then just lengthen the controller cables?
hey /diy/ ive go some EPS foam (kinda like the stuff in the image) and have to make 4 miniture sculpture like peices/models that represent hierachy, chess pieces ar out of he quesion, I was temted to do differnt stormtrooper helmets,but they would be hard to carve with only a file and sme sandpaper, pls help guys??
>>920501 pick up a hot wire foam cutter to get a rough shape of what you want to make and then go from there. You can get one for about $12 USD that takes 2 D batteries, but it is limited on how deep you can cut and how big of the piece of foam you can cut. I use one for when I cut stuff out of 1" to 3" pink insulation foam for molds when i cast stuff out of aluminum.
so I've decided my next project is going to be building a basic 4 piece drum set (2 tom toms, a snare and bass drum)
I'm hoping to use pre made shells, as i havent got the tools or space for those tools to make them myself. Im struggling to find a place to source the materials i need. does anybody know where I can source drum shells, lugs and hardware of custom size in the UK?
also anybody who has built their own instrument would be great to hear about it, any advice on my project would be appreciated
>>920448 Why does the hardware need to be custom? Why not use "replacement" hardware? It seems asinine to get a 14 inch rim custom made for a pre made 14 inch shell. Same thing with the lugs and tuning screws. It's just going to be a lot of extra money to get this stuff machined when parts that do the same thing will do the same thing.
You're probably not going to find this stuff locally, an if you do it'll cost more than what you can find online.
Since you are buying the shells, you can... oh, you are buying the lugs.... oh, you are buying the hardware. I guess you will diy the skins? If you are buying the skins too, you may as well just buy a used drum set on ebay that has the kind of shells you want, and do some finessing/finishing to make them sound and look great to you..
afternoon folks! I've been doing a lot of projects that require the use of a respirator and have decided to invest in a reusable one (where you replace the filters) as opposed to the inexpensive one time use masks. I've been trying to do some research but I'm still not sure I'm making a good decision. Rather than try to talk to the folks at the home goods stores, I figured I'd come here first for recommendations on both what kind of respirator would be good for me as well as a good market to purchase it from.
From what I've read, all manufacturers... Comment too long. Click here to view the full text.
>>920446 every box of filters i ever bought had a table on the back showing the protection levels required for pretty much any activity the finer the filter the more it will protect you, but if you buy a really fine particulate filter and then use it for something that doesn't produce really fine particles it will just clog up really quickly and you will have wasted money on a filter you didn't need. so sometimes its better to buy a couple to cover the different jobs you need to do.
closest store to me only does one kind of filter anyway and its cheap so i just use whatever, as long as i can't smell anything and my boogers are green instead if black at the end of the day i'm happy.
>>920446 Prolly you have somekind of specs in your country. Just read the labels and you'll find the correct level of filtration. And if you buy a cheap one it might not be that comfy. We have a chain called biltema and though it has the same specs as my M3 the M3 kicks ass as it is so much nicer to use for longer periods. Costs 5 times more though.
one of my peers whom I was speaking with on the subject said that his beard factored into the effectiveness of the mask too. Is there a way around that, short of shaving? In the type in the OP pic, it seems that any longer facial hair would allow particles into the mask.
I'm moving to a new apartment, and in my new building, each apartment has its own corresponding "basement" which is basically a single room w/ door found in the underground hallway, accessible by the stairwell. Most people use these for storage but I've noticed mine is fully equipped with electrical outlets and heaters. It's big enough to set up some sort of office or vidya center (inb4 cuckshed) but I'm not sure how I'll get my wifi down there.
I've seen these wifi repeaters... Comment too long. Click here to view the full text.
>>920365 Just like property management won't let me set up a repeater in the common areas, they certainly won't let me run cable from my front door, down the stairwell, through the basement hallway and into my basement unit.
I have a side by side fridge in garage that's acting up. The refrigerator side isn't working right... it's drifted up to 60F in the compartment. The freezer side is fine.
I've dialed up the cooling setting on the fridge side and gotten that side down to 40F (was set at 4/7, now 7/7).
Something's obviously wrong with it, but I don't know enough about how these units work. The cooling / compressor's functional, or it wouldn't cool at all. Thoughts on what I should look at appreciated.
