This is turning into quite the elaborate project! I'm waiting to see it in operation...

Hooks to hang the vacuums controls wherever is best. The level sensor cable is kind of special and is 15', so in order for the sensor to reach all the drums as I move the primary separator to empty drums, the 15' is going to be a limiting factor for where this box can be, so I made hooks.

These are 3/6" x 1" SS flatbar. I used heat and a big hammer and a larger vice to fashion the hooked ends. Drilling the four holes (to mount the hooks to the cabinet) and countersinking them took me a stupid long time today.

Cutting 3" SCH40 PVC pipe

I used a chop saw for my first four cuts . . . and what a mess it makes. Perfect cuts, almost no deburring req'd, but plastic shavings everywhere, even with a vacuum plumbed to the saw's exhaust. A huge mess, and I've a lot more cuts to go, so . . . I bought more tools, of course.

PVC pipe cutter, Ridgid 154-P (31657) will handle 1.5-4" IPS.


When combined with a big pipe vise (which I don't own) or a strap wrench (yeah, I've got one of those) it works really, really well.

No shavings to chase! I crank the knob about 1/3 turn for every revolution around the pipe, and it requires around ten revs to part the piece. However, it does leave a significant burr on both the ID and OD . . .

. . . more tools! Reed Tool DEB4 works perfectly for removing the OD.
This thing works SO slick on 3" SCH40 PVC. Snap it onto the end of the pipe (takes a bit of force), then a single revolution removes 90% or more of the OD's burr, leaving a beautiful, consistent chamfer. I am a novice, so I make two passes, but hardly anything is removed on the second pass.

That leaves the ID's burr, which I handled with a standard deburring pencil with swivel head (I don't own that one, but one similar).
A couple of swipes of the ID, and done!

Some pretty neat tools there, and nicely photographed too, by the way...

Ref. post #10

I got to thinking about the vacuums sequencer, and decided that I need to design for the situation where the ultrasonic sensor decides a burst of heavy dust or whatever is "full" and sends a one-second "turn off" blast, shutting the system down and then immediately restarting it. Today, I installed a 5th TDR on the sensor's output that delays turning off the system until the sensor outputs "full" continuously for 10 seconds.

Two hours to figure out how to use Inkscape again and update the drawing, two hours to add the relay, change some of the internal wiring, including adding a couple of segments, and bolting down that diode. The outside looks the same, but five time delay relays instead of four, and some cute labels on them:

It's getting kind of crowded in there, and my lack of controls (building) experience shows, but then nobody will see this, so who cares?

That IS getting pretty full in there. Reminds me of when I re-did the console wiring for my boat...
