Re: 8hp vs 16 hp

5D57CDF1-ABB9-4922-8D66-25B188C7C063.jpegYeah I didn’t think it necessary. Well built I guess but will gain a lot of real estate taking one motor and pump unit along with hoses out. Not to be too pedantic, but the correct term for those two oily things with the fins that make noise and horsepower i...

Even the largest 1.6 scale diesels generally just have one motor/hydraulic system and typically 16hp is more than enough.
What do you mean by "one motor/hydraulic system?"

Re: 8hp vs 16 hp

Probably not enough info, but in a generic way in 1.5 scale how much difference does it make? I have a PA that is set up with twin 8hp kohler engines driving twin hydraulic pumps which come together in a tee before passing through the valve and on to the truck mounted motors. My track is not ready ...

Might be interesting to hear from the original poster. I think he was looking for a welder, and with the currant direction of the thread.....gave up.
If you use a big enough audio amp you might be able to strike an arc somewhere. :D

Re: Welding Machine

The amazing thing to me is that it's a transistor amplifier. I didn't know McIntosh made those. McIntosh started producing solid state gear in the 1960s, around the time production yields on NPN silicon power transistors substantially improved and wholesale costs came down. Their principle competit...

Re: Welding Machine

On NEMA motors that's called the "service factor". IIRC 1.15 is typical. According to Wikipedia the standard says the each hour at that load takes two or three hours off the motor life. However considering that NEMA motors are rated for full load operation 24/7/365 you aren't likely to see the moto...

Re: Welding Machine

Could be a marketing ploy... like buying a 110V vaccuum cleaner that says it's 5.5 HP. It along the same line as claiming a home stereo amplifier produces 1000 watts output. Yeah, right... :D Have you checked McIntosh of late? They offer one that exceeds 1,000 watts. https://www.mcintoshlabs.com/pr...

Train mountain has very large turn radiuses if I remember correctly. On my 12" gage RR I'm stuck with ~40' radius turns and expect some wear.
Just oil the wheels and you'll be fine! :D :) :shock: 8) :P :roll: :wink: :lol:
