It sounds kinda like you're arguing with Bob . I'm not going to get in the middle of a debate about how capable the oil pump is.
My bigger question to all of this was- will this machine do what I need it to do, even at a slow speed? I'm new to using industrial machines, so the ins and outs of what a particular machine is capable of are outside of my realm of knowledge.
I have talked to three different dealers, one of those being Bob, and all have said that there should be no issues sewing at very slow speeds with the machine. That is regardless of whether or not the oil gets pumped. All three have said that either unthreading the machine and flooring the peddle for a couple of minutes, or winding a bobbin once a day will easily do the trick and there should be absolutely no issues. Wiz, even you said that above.
It was reinforced by the dealers that the machines can actually go for quite a while after being oiled (I'm sure this depends not the amount of use of course), but Bob said that he knows people who will only manually oil their machines once a month with no issues. Another dealer said at a high work load, it should only need it about every 8 hours. Thats about a full days work. I even saw a manual for an older Consew machine that recommended oiling every 8 hours of steady use.
So whether or not the pump will get oil up into the machine at a slow speed, it sounds to me like an auto oil pump will be no issue at all as long a regular habit of running the motor once a day at high speed is established.
Now if you guys want to continue to debate the abilities or shortfalls of an auto oiler, be my guest. Thanks for all of the advice though guys. I appreciate it.
