Hello fellas, I built this "workbench" today from a couple pallets and liked the result, but it's kinda flimsy and I'm thinking of ways to reinforce it (It doesn't need to be pretty). I'm not into woodworking, that's why it may look amateurish.
I don't know if many housebuilding type people are one here much but I'd kinda like an opinion on something, do ya'll think a small A-frame second story would look good on a 4:12 roof? I was never happy with this roof pitch, and the damn place is too small already.
>>928283 But it's kinda the only way, all exterior walls have the (also expensive) siding up; an a-frame could be put directly on top of the existing roof so nothing would be wasted unlike if I tore off a wall of siding or a whole room.but all that being said I'm open to all ideas
Hey diynos, I had a party at my place and woke up with pic related. I had an older leather couch pressed near the wall, didn't know the corner was exposed and the steel edge dug into the drywall something fierce when one of my buddies laid back into the wall. So now I'm stuck with this, coke can for reference. Best way to fix it? California patch wouldn't be ideal, but I will do what I have to do. Thank you for any advice you may have.
So I bought this 105 year old house. Its still got trim up from I am assuming the early 70's or earlier. Its all really wide and thick trim. They have been painted over atleast two or three times with white paint. It looks good and has a clean modern look, my wife and I prefer that dark chestnut wood stain you find in old homes. I got two floors of this trim/baseboard, about 6 doorways, and two large archways. It would be a big, messy, and tedious task.
What I want to know is how long wood it taketo strip paint, sand, stain, seal. Keep in mind I got kids too. I dont... Comment too long. Click here to view the full text.
I come to you with a vocabulary question and a terrible illustration.
I am looking for something much like a pogo stick, but a great deal shorter, perhaps four to eight inches. You could also consider it a shock absorber, but I thought those were hydraulic. It would need fasteners on each end, plus some mechanism to keep it together.
They'd come with a variety of spring constants so I could Hooke's Law out how far it would move under a given force.
Does this thing exist, and if so, what is it called?
I guess that'd just be called a spring. A spring and a shock absorber are two fundamentally different things. A spring reacts with a force proportional to how it is compressed or tensed. A shock absorber reacts with a force proportional to the speed with wich its end is displaced.
Why do you need to encase the spring in these cylinders? Depending on the forces involved you could use pvc pipe or perhaps get a telescopic fork from a crashed motorcycle. When bent the fork tubes are basically scrap metal, but they're usually bent within the top 6 inches or... Comment too long. Click here to view the full text.
The price to buy a wind mill to generate electricity is outrageous. I don't understand why they cost thousands of $$$$. Why cant I hook up an altinator from a car to a wind mill to charge a battery? It seems like a simple idea, and I have the ability to make the wind mill.
if you wanna connect the blades directly to the alternator, it wont work coz the rotational speed is too low. you'd have to rewire the alternator to compensate. however if you have a windmill, then presumably you can use gears or belts to obtain the necessary speed, so it could work unaltered.
This house is a bit over 100 years old, there is a living space in the attic, however it gets over 100 degrees in the summer, and cold in the winter (California). I've gutted the old Celotex walls and ceiling and haven't found any moisture issues or a drop of water even with all the rain we've been getting so the roofing is in good shape. There is no plywood or any sheathing on the roof or walls, just planks on ceiling with an inch space between them,... Comment too long. Click here to view the full text.
So I decided to build a oven for various projects, heat is always needed! The plan is to scavenge the heating elements from a sauna heater which are abundant here in the land of glory and heroes . The oven itself is easily created out of fire bricks. But is there some thingamajig that could regulate three phase heaters? I presume these heaters work with phase to phase voltages that translate to 380V. I can follow the heat inside the oven with some probe so no automation is needed, just a knob to turn which regulates the heat inside. The amount of power needed to be regulated... Comment too long.

>>928031 I'm building one too, but mine uses normal wall outlet electric. Just 124v 15A 1850W maxes for the outlets it would use. It will be heavily insulated so that only a small amount of power will be needed to build up a lot of heat.
Since you are using fire bricks, what will this oven be used for? Normally you only use fire bricks for some heavy duty, high temp use like a foundry & furnace or kiln. Otherwise, the bricks will take forever to heat up for lower temperatures.
Mine is just for food cooking... Comment too long. Click here to view the full text.
>>928159 My friend is a blacksmith (that earns his living with smithing) and we were talking about steel one day driving around. I unfortunately don't know the vocabulary in English but certain shit you do to steel needs specific temperatures. You know what I'm talking about. I want those temperatures and it won't be too hard to build the oven part. But to control the temperature one needs a way to regulate it. And this is something that is new for me. Three phase regulation.
And with the option to turn... Comment too long. Click here to view the full text.
if you can into schematics and datasheets, look up this regulator chip, or similar: AP34063
otherwise, ready made circuits can be found by googling. one easy way is to use a Blackberry car adapter (charger) with takes in 10-25V and puts out 5V. $3 at the thrift store. other brands may work, but are not specifically rated for 25V.
>>928027 It's not 'milliampere-hours', it's just milliamps, and it's not '0.28mA', that would be 280 *microamps*, it's 280 *milliamps*, or 0.28A.
Now, then.. what you need is a step-down (or 'buck') switching power supply. Since you need 5V (not 'around' 5V, it's *5V*) you can get a module that does this off-the-shelf -- which in your case is a good thing, since I don't have much faith at this point in your being able to actually construct one.
>>928027 ..oh, and since you're confused about it: 'milliampere-hours' is a unit of measure you'd use for a *battery*, not a solar panel of any kind; it's a unit of measure with regards to *storage capacity*.
