/k/ here. I humbly request your shared knowledge on hydraulic shot presses. I could always just buy one, and still may, but I like to build things for myself. Can anyone provide schematics, or a parts list, or any other advice for building a 20 ton shop press? Will be used for bending sheet and plate and pipe, but also to press the occasional barrel into the odd trunnion, and who knows maybe I'll rebuild a bearing or two.
Going for basically pic related, but much taller, and possibly on a cart or with its own wheels.
My biggest obstacle here is that I am shit at welding. So my question here is can a build like this be done with just nuts and bolts and bushings? Are there any deal breaking cons to building a press which is held together with huge nuts and bolts rather than welded joints?
Additional questions. What gauge rectangular tubing/ channel/angle sock should be used for the frame to withstand around 25-30 tons of load. I want to overburdened it in case I someday decide I need more dakka.
>>935269 >What gauge rectangular tubing/ channel/angle sock should be used for the frame to withstand around 25-30 tons of load. I want to overburdened it in case I someday decide I need more dakka. The AISC has a very handy resource available that details exactly how to calculate loads. Start from the beginning of the code book and you might actually learn something useful. It will answer all your questions. If you want to just be on the safe side then i'd go with 3" thick solid steel square stock.

I lie to myself that I'm looking for the "perfect work glove" but I know that no such thing exists.
One of my favorite though is pic related: Rig Lizard Oasis 2022

Uhh, mechanix. Whichever I see first that have impact protection. I buy them on a pcard, so I'm not ordering odd-brand shit like 'rig lizard', and every other glove brand available in stores besides mechanix and monkey grip are shit.
I got bored and decided to do the math on what it would take to make a moon base out of modified intermodal containers.
First, some basics:
- An unloaded, stock 40 foot intermodal container weighs about 2.5 tons, a loaded container can usually hold up to 8 tons - 1 atm of air inside it is about 14 lbs/square inch. Using that as a baseline, a container that could remain airtight in a vacuum would also need to remain watertight at a depth of 10 meters (where PSI is 30 lbs/square inches) - The Apollo program spacesuits each weighed about 145 pounds, with eight...

Hey /diy/. I've been wondering... how hard is it to convert a gasoline car into an electric car? Unfortunately, I have this Bora in my backyard taking up space, and the engine is completely blown. However, someone did the favor of taking out the engine and now it just sits there with no engine. I've been wanting to convert it to an electric car since it is very lightweight and the trasnmission ( I think) seems to be okay. How hard is this, and has anyone done it? I have some skills in circuits, but by no means am I an electrical engineer. Thanks for any advice!
Average cost of conversion is 10K. It won't be practical and it'll take a lot of time, unless you know your way around a wrench. Google around for conversion kits and figure out how you'll get power steering and brakes again to start.
You set up 'zones'. Each zone is run for a particular length of time i.e. 1 hour. You can then use different emitters to control how much flow you get out the end. usually 1/2, 1, and 2 gallons per hour.
You're also limited by tubing size. for example my lines I buy, the 1/4" tube is limited to a 30' run and can supply 30 gallons per hour. So I can take a 1/4" line and put a couple T's in and get 15x2gph emitters.
The zones... Comment too long. Click here to view the full text.
Using only rudimentary aluminium casting techniques, is it possible for me to make a mechanical system that causes a large (2m across maybe) parabolic dish to track the sun, without using electrical power? Also, how easy is it to make solar-powered thermoelectric generators?
>>936291 a small solar panel, a battery and a linear actuator and levers. using a solar panel would be cheaper and easier than any other option. although, if you wanted, you could build some kind of complex orrery powered by hamsters or the suffering of mortys.
>>936293 Even when dealing with extremely concentrated sunlight, is a solar panel superior to a thermoelectric generator? Pi square metres of sunlight is a lot of energy for a small solar panel to take...
>>936296 no your problem is that you need power to be input to the system. equal and opposite force. laws of physics here. so one way or another, you need power. a small solar panel say a 40w and battery will give you enough power to shift a parabolic dish across 60 degrees once a day for sun tracking purposes and return to starting position for tomorrow. now what is your dish for? why do you think a small scale thermoelectric generator is better than a solar panel for your application?
Hello /diy/, I was directed here from /mu/ I plan to order a white pickguard for my strat and put some art on it. How much work will this be? What materials and products will I need? I was planning to use acrylic paint and just put some clear coat on it. Will this suffice? Tips, suggestions, experiences? Obviously, I want the art to not wear away from my fingers constantly touching and scratching at it.Any help is appreciated.
I'm thinking about setting up a bitcoin farm at my workplace (free electricity, privacy) starting with a 1000-1500$ budget, anyone has any experience in bit mining? I'd like to know some good equipment/setup for this
>>938328 this, make a sanding bow. you wont get the crisp tight curves, but should get something usable. also, round off the edges as much as possible with a knife or chisel, will be much faster than sanding it down. (don't use knife with drill and with drill press only if you have a centerpoint on the bottom too. too much sideways force otherwise.)
Sup /diy/, welderfag here. I'm looking to start doing some metal fabrication at home. What are the basic tools I'm gonna need? I wanna build stuff similar to pic related eventually. Also does anyone have any recommendations for a tig welder that can run off household power?
After years of apartment living, the wife and I are finally moving into a big-boy house. I want to start investing in some decent tools that will last for a little while but not break the bank.
The first one I think I'd like to bring home is a table saw. Any suggestions as far as what brands to avoid, models to consider, or if a certain tool has been especially good to you that you can recommend to a new buyer?
I guess what I'm really asking is what someone starting a tool collection should prioritize
