New info from Grizzly tech support -pulsing at low rpm
Hello everyone,
I heard back from Grizzly tech support on the "pulsing at very low rpm" issue that I and another owner have reported to them. The engineers have said that they got the specs wrong, even in the catalog and online.
They say that the Low rpm specs should be 100 rpm, on the low belt setting, and the high belt setting low rpm spec should be 330 rpm.
I pressed the tech guy as to why some owners of the Laguna model report no problems with their version, and the reply was that they cannot speak to the machines of other companies, but that this lathe was made to their specs. I then said that even the labeling on the lathe itself is wrong; they said "correct." Even when I asked about the inverter being reprogrammed, the engineers say that is not the problem, it is simply their specs to which the machine is built.
For me, in the grand scheme of things, this "pulsing at very low rpm" is a mostly minor annoyance, and not a true hindrance to achieving good turning success. Most of my years of experience of turning have taught me that it is very rare to need anything below 100 rpm, and sanding and finishing on my previous lathe was limited to a minimum of 400 rpm, as that was the minimum speed for that lathe.
Most machines [except Oneway and Robust] are manufactured in China, and I have noticed as of late that there are owners of Jet and Powermatic that are speaking of problems with their machines, so I guess that it is a "try to do the best you can" deal. The other problems are being discussed on "another forum" [runout on a Jet(spindle, bearing issues) and shimming tailstock to align with headstock on a 3520b]
Grizzly has a return policy, and said they would pay the shipping back to them, but as of now that is not what I want to do. Again, I see this as a very minor annoyance rather than a problem that hinders me in turning projects, as I would most likely have very rare use for less than 100 rpm.
My bottom line - for me personally, is that I still believe that I have a good machine with good features for a good value. That was what I was looking for when I made my decision to purchase, and what I want for the future is longevity, performance and availability of parts and service in the future if it is needed.
I hope that my perspective helps any out there that may be considering the purchase of a new lathe, and had this one in mind to look at.
