Coming to the cattle forum to get more opinions on backyard dairying. I've been doing a lot of research over a few years on putting together my first milking machine. I'd really like to get it going before March because we will be freshening 4 goats. I'd like to milk 2 at a time. I've got a complete 2 goat bucket setup from Parts Department. (http://www.partsdeptonline.com/COMP...TS-70-W_62997-CLUSTERS/productinfo/962685G-2/ THIS ONE to be specific) I am looking for a vacuum source that won't break the bank. Tried keeping my eyes open used locally, but many need repair, aren't sure if they run, and having no experience or time, didn't want to go that route. Tried emailing Perry's milkers about a vacuum source but received a snarky reply after sending them a link to a pump I was looking at at amazon and then following up with "will it work and if not, what would you suggest that you sell?" Received a snarky response I think due to the email formatting with the link, and they missed the "sell me something" part to my email. I replied to clarify and haven't heard back yet... But don't really appreciate the instant slightly snarky response as a customer either. This is the one I'm looking at on Amazon, a 12cfm 1HP: https://www.amazon.com/gp/product/B00XFLA2MC/ref=ox_sc_act_title_2?ie=UTF8&psc=1&smid=A2QSX0WT38UK5G I would be making a PVC balance tank with a vacuum gauge and pressure regulator and shut off. The response from Perry's made it seem like it wouldn't work because it's a constant vacuum, but without further explanation - I have a pulsator on my bucket? I'm just hoping to not eventually get fed up with figuring this out and buying the mobile 1295.00 vacuum source from Parts Dept on a payment plan. I'd really like to not spend that much money if possible, but maybe it's worth the ease factor for someone like me with zero experience in milking machines and quickly getting frustrated with conflicting information. I know I've seen other systems with a vacuum pump similar to the one on Amazon and just don't see why it wouldn't work. This DIY uses a 6cfm: http://smallholderhollow.com/projects/diy-milking-machine/ Anywho, just looking for some advice. TIA!
