I know this thread is 10 years old, but I figured I'd post the info here for future reference. From astm f1807 standard

You can probably trace the wires for alarm, fan, compressor etc & hook them up. Schematic is on the control

I don't have the drier on mine. You should be able to email oppair for instructions.

Yah, thanks for the input. I was trying to work out the basics but I keep getting lost in the calcs. Those prints aren't meant to be final but to explain the concept. Culvert is shown for elevation, it will actually be on an end wall, with a sealed blast door.

Here is the entire Swiss guideline. It is a design manual for approved shelter construction. In other words, shelters have to be built to meet these guidelines. The Swiss are considered the experts in this field, and they went to a whole lot of trouble to write these guidelines. There are many...

The Swiss guidelines have formulas for most of what I need. I just have to figure out how to apply them. I may well end up having to hire an engineer.

Here is a design example from Swiss guidelines.

These drawings give some idea of what I'm working on. Existing house on left, new addition on right. Includes "root cellar" as shown. Pretty good with walls at 10in thick. Ceiling should be ok at 12 in thick with the right rebar reinforcement. Thinking about casting a beam as shown for...

Anyone out there have a little time to talk about concrete engineering? Mostly need to calculate proper rebar amount for loading. If this is your area of expertise and you're willing to share it would be most appreciated... Thanks, Bryan

Thanks! Inside is ratty, but I don't care as long as it is dry! And it looks OK on the outside.

drawing i sent to spring company. You have to weigh the outside edge of the door when level. Because of the angles involved, the tension needed to lift the door is higher than this weight. Plus, you need to have the proper size pulley to accommodate the cable length when the door is up.

Like many others here, I have too much stuff and not enough room for it all. It's gonna be a few years before I can build my shop. So I figured I'd buy a shipping container for storage in the meantime. However, they aren't cheap, they are very heavy and hard to move. For my needs, I decided...

But what do you need for EMP/HEMP protection...

Personally, I'd rather get the compressor set up for single phase. Setting up a VFD can be a challenge especially to optimize everything. I do believe other manufacturers offer single phase options, usually 3 phase machines where the VFD will work with single phase input. So far I am pleased...

We use Prusament PLA filament for our parts by default. It is plenty strong, and resistant to oil and gas. SInce the letters are printed in color, the color won't wipe off. If someone has a need for very high heat resistance, we would use a different filament.
