QUESTION:I do vacuum forming in my garage. I'm currently using 2 shop vacs in
line, which is producing 8" of vacuum. I would like more vacuum for
better detail, but don't want to spend thousands on a vacuum pump. I
would appreciate any suggestions for obtaining more vacuum.
ANSWER: Its the ultimate electrical equipment restoration/repair tool - hook
one up to each piece of electrical equipment to catch the smoke they
run on if it escapes. Now if we can just find a practical Gas
Injector (and no, before you ask, Lathe Dorks, at least the ones young
Jim Harvey has for sale, can not be use for this).
Besides, you (and some undeclared stealth vacuum pump hoarders) have
the Ghast vacuum pump (I'm seriously jealous - I have no need at all
for one but I "want" one just-in-case - so not having pumps we are
gonna archive the tanks for the same reason you have the pump!
Actually, I have no use for a vacuum tank, I just couldn't resist the
mental exercise of understanding this small corner of MMS a little
bit. Actually, its all the fault of whoever brought up that
compressor stuff the last time - I was finally motivated to punch the
equations into mathCAD for the compressor so I could study them a bit
- and that lead me to upgrade my home copy of the SW to MathCAD
version 8, which is why I was on their (dead this weekend) WEB page
where I read about the Explorer and that gave me opportunity to have
the idea, looking at that nasty buckling general case formula, to put
it in MathCAD and post it for the group because they"should" be able
to get this free reader SW and "play" with it. Or at least those
moved by doing such things would.
Then the thread on the electrical equivalent of the 100 mpg carburetor
came up - I was for the second time misunderstood to be a NASA
employee - which I am not. I got over that and went down to measure
my pool pump current and discovered low filter pressure. The pump was
all plugged up - had ingested pepper tree leaves ... again (I wanna
take the excavator to that tree!) - long and skinny, they snake
through the strainer and fold themselves double in around the entry
edge to the volutes of the pump and reduce its efficiency to zip.
BTW: It needs 5.8A to spin its impeller in a water bath and do little
pumping - not anywhere near the power it consumes at full load, which
an alert obeservant person might note for later reference.
