Foketry: I really like the valve covers. Are they 3D printed plastic, or are they cast like some of the other parts? Also is the raised container on the right-hand side in the video, is that the fuel tank or something else? Don

From the number of anchor bolts you must be expecting to lift some serious tonnage with that crane. It looks good, might need some counter-weight though.

Most electrical equipment - circuit breakers, switches and wiring, is rated at 75°C. The better stuff, read more expensive, is rated at 90°C. Most electrical equipment manufacturers don't want to see their stuff running at more than 40°C above ambient. I'd be concerned about the plastic parts...

If the temperature of the pressurized air was hot enough that you were concerned about your plastic bottle, what about that poor motorcycle fuel pump? Isn't it going to get cooked in there? The temperature's gotta be way above the design rating of the the pump. It would seem to me that pump...

Slow-blow fuses have been used for many years for motor protection. They are a time-delay fuse that will tolerate the normal in-rush current of the motor, yet still give some overload protection to the motor. There ARE many better ways of overload protection, but a fuse is always the simplest...

Steamchick: I would normally say that no, one SHOULDN'T affect the other. But then again you never know what kind of tolerances were designed in, or weren't as the case may be. My Wanhao D6 clone 3D printer originally had a relay rated at 10 amps controlling a circuit that routinely had more...

Don't know why I never found this thread until now, but I'm glad I found it. I USED to think that I was the only one with a shop that has almost every flat surface covered in stuff. And not just any old stuff, it's important project stuff. I can usually find a square foot or two to work on...

Hot water heating systems or in your case that's more likely to be chilled water systems, would have similar problems. You might check with Heat-Ventilating-Air-Conditioning companies in your area to see what they would recommend.

If by chance there's any leftovers, let me know. I live in NE Iowa and could easily do a day-trip out that way.

When you say 2mm wall thickness, does that include the top and the bottom? My slicer has separate settings for perimeter walls, and the top/bottom. When I have a print that needs to take a beating, I never go below 40% infill. When watching the printing of parts with various infill...

The wall thickness MIGHT have survived if it had more infill backing it up. How thick were the perimeter walls, the top, and the bottom? What type of an infill pattern was used? It looks like it could have been rectilinear which would have good adhesion between layers where they cross, but...

Congratulations on your first 3D printer??? Welcome to the nut-house/rabbit hole? 3D printers should all come with an "Abandon all HOPE ye who push the start button" warning label. I'd have 3 warning labels now. If you are saying, like I think you are, that Layer 1 when printed is wider than...

"I had to look up VWPBL ..." Don't feel bad about that Andy, I had to look it up too.

So I take it that you gentlemen have no qualms about watching videos of the guys doing aluminum castings of fire ant nests? That is, other than the fact they're pouring molten metal into a hole in the ground?

Anybody else on here visit thehomefoundry.org? I haven't been able get access to that site since the first of the year. I keep getting a server timeout error, I'll try later tonight to see if I can get on-line. Hopefully it's something simple like there been a tremendous up-swing in the...
