    3D Printed Metal Engine Parts

    I haven't tried either of these ideas, but..... Printable waxes will also need supports for most overhangs. If you have a printer equipped with 2 extruders then one of those could be the printable wax and the other could be a water soluble material used just for supports. Telling the printer...

    What Determines the rpm of a engine?

    I had to go back and look at it myself. That's a nice looking block, but you've got to admit that not everybody as access to the kind of equipment required to do that.

    Anybody else having trouble logging into thehomefoundry.org? Or know what's going on there? I haven't been able to get logged in there all week, I keep getting a Network Error message when I try. Don

    Welder

    A laser welder that has the capacity to weld more than thin sheet-metal is probably going to be either in the KW range, or the kilo-Buck range, or more likely both. Welding takes practice, I was taught to gas weld sheet-metal about 50 years ago and there is a learning curve. I can stick weld...

    18 Cylinders Isotta Fraschini (straight six-cylinder x3 )

    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

    Not an engine! More a "function model" of a machine.

    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.

    Monotube Flash Boiler Design

    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...

    Monotube Flash Boiler Design

    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...

    Protection to Micro lathe power supply?

    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...

    HELP, my shop is a MESS

    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...

    HELP, my shop is a MESS

    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...

    Which Spindle coolant to use?

    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.

    What Fillament, wall thickness and Fill Percentage for Patterns

    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...
