Re: Energy Rotary spool valve
don’t quite understand the drawing What you are seeing are ANSI fluid power symbols . Ports A and B are the load, P is the discharge from the pump and T is the return line to the oil reservoir (tank). The object below the valve spool schematic is the internal relief valve. If it cracks, it divert...

Re: Energy Rotary spool valve
Good evening, I am trying to understand the operation of this valve, the valve has what I assume to have 3 positions, right (forward) left (reverse) and center position which I assume should have no flow and act as the stopped position, I am correct. The valve P/N 10240 . See attached. It should a...

Re: SB chucks rotary table and misc.
You might get more interest if you post about your stuff here, instead of making forum members go to a social media site to read about it. I, for one, don’t do Fakebook, Twatter, Instagarbage, etc., as they are intrusive and fill the screen with advertising and other malarkey in which I have no int...

Re: 30 amp alternator
The way the alternator is physically connected to the V twin. Thanks The alternator is driven from a stub PTO shaft that is bolted to the face of the engine’s flywheel. A jaw-type “flexible” coupling (aka “Lovejoy coupling”) is used to make the connection. I don’t recall precisely how the couplin...

Thanks
You referring to the electrical connections, or the way in which the V-twin drives the alternator?

Re: Left handed lathe, for lack of a better name
Us lefties wish there were more tools built for us... Yeah, it would be nice if there was such a thing as a good-quality, left-handed micrometer. The Roman Catholics tried to beat the lefty-ism out of me, but weren’t entirely successful. :D :evil: I was young enough when exposed to them to learn ...

Re: Aquarium Air Pump for chip clearing?
I don’t use air to clear chips while cutting. It’s darn near impossible to get them to go where you want them to land. I do use a hand-held blowgun to clear chips after stopping the machine. Been doing that for as long as I’ve been making chips, which is about 65 years. Yikes! Is it that long???...

Re: Timing belts
Unfortunately, designing a reliable timing belt drive is not a simple engineering exercise. In another life, I did such design work and can attest that there are quite a few variables to be considered. Also, timing belts are best used in moderate torque, elevated RPM situations. Low RPM and high ...

Re: Drilling holes in brass, should I pilot hole?
Here is an image of a twist drill dulled for cutting brass/copper alloys. I use a diamond file to carefully dull both edges. The drill might squeal some during cutting, but I know it is drilling correctly. I don’t do much work with brass, but when I drill it, I usually use a little WD-40 to get rid...
