Interesting. My city just implemented a new fence ordinance. All NEW or REPLACEMENT fences, MUST have tubular metal fence posts set in concrete. The size of the tube and the depth of set and the diameter of the concrete surround are specified by the ordinance depending on height. The ordinance...

Glad to see that you are back in business. We have missed your updates and your fine craftsmanship.

Since both tanks have dished heads the math is not trivial. Defining the intersection on dished heads of two different sizes would probably take longer than the "cut/fit/repeat" method. I can think of two shortcuts: use a short piece of six inch pipe to join the two tanks, much simpler to figure...

This. Least amount of work to set up, so you might actually use it.

Incorrect. The expander IS the regulator. The drop in pressure results in a drop in temperature. The Joule Thompson effect is a standard tool used in industry to cool gasses. Most of the commercial oxygen and nitrogen are separated by cryogenic distillation after cooling the gasses to liquid...

The device in question uses a Joule-Thompson expander as a regulator, coupled with a coalescer to bring the micro water droplets together into larger drops that will not be carried out of the chamber. The science is sound, it could work. Note that the example calls for 50-60 psig pressure drop...

Your Dad put in half the hardener, not no hardener. You yourself said it seems to be hardening. Heat will accellerate the hardening, so if you have some way to add heat to the floor, that will speed up the curing. Don't be too quick to give up on your floor. If you are up for some crazy advice...

Or an Instructor.

Bull Frog Vapor Corrosion Inhibitors. Open the package, put in toolbox, vapor coats metal, stops corrosion. No greasy film.

Let me add a cautionary note: I bought some PVC brickmold at Lowe's three years ago and used it to replace some old pine molding. I painted the trim a red oxide color and it held up well for two years. Not the paint has spalled off the P avac in many places. The worst problem I have with the PVC...

It's not horizontal either.

You mention local sawmills as a source for your wood. Is it a requirement that you use locally sourced wood for your project? If not, then red cedar or redwood will be the longest lasting and most economical choices. Since both these woods splinter as they weather, they should be painted with a...

So you know my friends Squint, Lefty, and Nine Toes!

Thank you Ryan for showing us the video of an awesome home hobbiest woodworking shop. It was fun seeing the typical Architect's building techniques: celestory windows, single pitched roof (think 50's tract houses), self designed details (wood storage brackets, french cleats, dust collector...

Once again everybody is talking apples and oranges. The Eastwood Concours gun is $160 with one orifice/metering rod. There are 4 orifice/rod sets available, from lacquer to primer surfacer. The Sata 5000b is $500 and you cannot buy it on the internet, you have to find a real store that sells...

Here in the DFW area the authorities want the insulation left on the wire so they can identify where it came from. Several youth ball fields have had all the wire for their lights stolen, including the wire inside the light poles. Therefore, by definition any wire with the insulation burned off...

That particular Chraftsman vise has made the rounds on Ebay at least twice that I know of. He is essentially charging $100+ for the polish job. I have three of the same model in like new condition sitting on a shelf waiting on my spray gun. I prefer paint to polish.

The C clamp looking tool looks like an early brake lining friction material riveting tool.

Excellent finished project. You have shown us that you have an artistic eye.

Technically, you built a welded steel tube fence. Nice enough, but I would have been really impressed if you had built a real wrought iron fence. Your steel fence should be good for 10-20 years, but a wrought iron fence will last 100 years.
