Topic: 1250W Pumper air flow (13 msgs / 206 lines)
1) From: Peter Elkins
Hi.  I've mostly been a lurker here, but I did post a while ago about P1
mods.  I recently found a Wearever Pumper (1250W), and have been trying to
increase air flow.  I read here (I think) about prying open some of the
vents.  I did that, had some difficulty getting everything back together.
However, in the end, it helped dramatically.  I'm now able to do 1/3 of a
pound.  The can I use for my P1 fits perfectly in there too.  However, I do
have to shake it some at the beginning, so I was hoping to increase air flow
some more if possible.  Someone mentioned drilling holes in the bottom/side
of the plastic casing.  Is this worth doing?
Thanks much,
Pete

I just completely remove the plastic and metal covings on my P1.  I don't 
bother with drilling.  I can do 190 g in mind this way.

Hmm...  an interesting idea.  Does everything stay together?  I've never
taken the P1 apart.  I think that idea wouldn't work well with the Pumper,
as the bottom at least seems to help hold things together.
Thanks,
Pete

Sigh, I just read my own message and "got" your joke. MINE MINE MINE :-)  I 
hate spell checkers some days.

I don't know for sure on a Pumper actually.  The P1 does stay together.  It 
actually takes a few other tools (2 different sockets and another 
screwdriver) to get it all the way apart.   It is really built like a tank.

I have a couple of 1250W pumpers. They are much like the WB poppery II inside.
The fan housing is made out of plastic.and much narrower than the 1400W.
Although there is a tripod mount as in the WBII there is no screw hole
through from the base to fix it through so it would be difficult to keep
together without the top.

Thanks, John.  I've got to try this.  Do the coverings come right out (once
you disassemble), or do you have to destroy them to remove them?  Ideally
I'd like to put them back in come winter time.  I roast outside, and
wouldn't want the extra air flow then.
Thanks,
Pete

Have you tried drilling a bunch of holes in the bottom (and/or top) to
improve air flow?
Thanks,
Pete

I did that on my 1400W but with the low voltage motor poppers like the
1250W pumper I just use the radioshack transformer and give it plenty. But
be warned you can burn out the motor trying to loft too many beans... They
will loft 7 or 8 oz but only for about 5 or 10 seconds, then poof, 3rd
crack before 1st or second. If you do burn it out I may have a spare...

Yes, you can completely take a P1 apart without destroying it.  It is fully 
held together by screws (12 I think)  Apparently the Pumper though is like 
a P2, so that may take hole drilling.  OTOH, the Pumper may not be inlet 
restricted.

Hmmm, just took three P1's apart the other week...
There's the four with flat washers through the feet that hold the bottom 
plastic on,
there's three small guys holding on the metal plate behind that,
three nuts for the wiring, with split washers, (watch for the screws falling 
out, seperate the switch wires now...)
followed by the three screws up top, (the body comes off now...)
two more hex-head screws holding down the plastic upper chamber, (flip it 
back over...)
three  looong hex head screws holding the rest together,
three teensy screws holding the fan together,
and two nuts with star washers holding the motor in. (now where did the 
screws these came off of just roll off to...?)
23 screws, 9 washers, and 5 nuts. It really helps to have a long counter top 
cleared off, set down everything in order, in a specific orientation so you 
can guess better how to reassemble, and if all else fails, have a spare to 
reference by!
