I also have a Logan 927 that I recently cleaned up. It's pretty beat up but works for me
. I had a spare 1HP Yaskawa servo lying around, so I rigged that up to replace the original motor/belt system. I was getting some belt slippage, so I started running 2x 1" flat belts at the same time to see how that would work. Haven't used it much yet since installing the servo(2 days ago) since I seem to have messed something up when re-assembling the clutch and power feed does not work anymore. This model uses regular deep groove ball bearings which I'm not thrilled about, but I replaced the original ones with some Nachi bearings and it seems to work very well with the bellville washer preload. Still have a good number of things left to fix, but this is where I'm at now.
