Re: Is spudding dead?

Funny, I only stopped by here after a year to see if anyone was still around as I was throwing out some half-finished pneumatic builds that were cluttering the workshop. The political climate here makes builds, whether pneumatic or hybrid pretty much impossible. For those Stateside, imagine all your...

Hi fellow machinists. I am adding a 4th axis to my CNC mill and need some advice on sourcing parts. I have the motor, gearbox etc, what I need is a 80-100mm self centring chuck that is mounted on a straight shatf, not MT arbour, so I can fit it to the gearbox. I also need a tailstock to suit. Having...

PIA but there it is. New firing plan Press button on Arduino, digital pin 1 goes LOW LOW state on pin 1 enables HIGH state on pin 2 Relay on pin 2 closes and solenoid trips P-A now enabled, chamber fills Ignore pin 1 thereafter, only needed to prime system Look for pulse on pin 3, that means FIRE bu...

Exactly the same way at 120psi The funny thing is, the solenoid has a manual trip switch, you can see the red button in the photo. P-A under pressure from the compressor, the manual switch makes a nice click and works. R-A which is what we want, manual does nothing, you have to use the volts on coil...

Yup
And a nice tingle from the 12v supply if you are not careful.

Are we going to need to get a room for the next bit ?

Three ports A, P, R, on each bit of kit. QEV A is chamber QEV R is breech block QEV P is fill side Solenoid R is compressor Solenoid A is fill side going to pilot of the QEV Solenoid P is vented Chamber fills, evilvet trips solenoid, nothing happens, evilvet considers the merits of tall buildings in...

Well dang it, it don't work. 1. Air line into NC port. Trip solenoid NC port opens and feeds QEV Chamber fills just like it should Release solenoid NC path is closed, pilot vents through the NO exhaust Chamber dumps out the R port just like it should 2. Airline into NO port Chamber fills Trip soleno...

@JSR
So if that's the case, the N/O solenoid will allow my chamber to fill form the compressor as if the solenoid was not there at all, yes ?

When the solenoid actions, the N/O port close, sealing off the compressor and the pilot of the QEV is exposed ?

More like my favorite airframe ever the undeniably beautiful A-10 How can you argue with an aircraft that "The A-10 was designed around the GAU-8 Avenger, a rotary cannon that is the airplane's primary armament and the heaviest such cannon mounted on an aircraft. " The sole purpose of the airframe w...
