 | Eva, i really like your web site - the repairs are quite incredible.
anyway, i have a question: are you familiar with the electric pumps tha women use for saving breast milk? would one of those pumps be suitable for vacuum bagging?
the pump is exactly the one in this aspirator, without the collection thing, and without a gauge. in other words i have the pump only.

 | Eva,
I have looked through your repairs and am in awe....keep my eye out for a hollmann on yachtworld...!
I have a question and its about the polystyrene I have seen in your pictures..It was my understanding that better boards were made with 2psi, B or C Grade styrene which I gather differs greatly from the Blue or White styrene one sees at hardware stores....But in some of your pics, some of the boards do seem to have the white styrene with large 'bubbles' similiar to hardware grade?
What are our boards made out of and what is reasonable to expect?
Thanks!
Ben

Hi Jeff: vacuum pump is vacuum pump. What matters is not its originally intended application :) but rather its capacity, both in terms of vacuum level (22"Hg is a whole lot more than your board can sustain) and flow rate (28lpm is quite respectable - in a pinch one can draw down large bags with a supplemental shop vac). And I like the strainers and such on this model, to prevent stuff from entering the pump - in our case salt water Go for it! Eva

 | i will buy a gauge for my pump. it looks like there is a valve or something on top of the pump that might be for reducing the vacuum. so, it appears that breasts are a lot stronger than boards.

Wait, don't forget it... I don't know about your lactation machine but it appears very similar to the medical Gomco suction machines that are prized by home vacuum baggers. Try it, slow but steady, it will probably do the trick. Refrigerators have issues: Unless rigged carefully, refrigerator compressors will work for only a short time before they run dry for lack of lubricant (in the closed loop system they're designed for, machine oil is mixed into the freon and is constantly lubricating the system). Refrig compressors are awkward to handle and tend to be filthy and oily. Still if finances are limited - here's why I'm writing - pick a refrigerator motor where the freon has been properly reclaimed first! There's around 10 cubic feet of freon (read: Chlorofluorocarbons) in a twenty year-old, undrained, discarded refrigerator. Most states mandate that transfer stations reclaim the freon before scrapping their refrigerators, talk to your dump operators. The closest I ever felt to being a Republican or a common eco-nazi was when a buddy and I needed a compressor fast and we dissected the motor from an abandoned refrigerator. Think about it. Use the breast pump. BL
