Hi All:
I just bought a Jones and Shipman 540 AP.
I've never run one before so I know nothing about how they're supposed to feel and sound.
Three questions for all you experienced J&S drivers out there please:
1) The cross travel is heavy...it's quite an armbreaker compared to the Kent I just sold whose saddle must weigh twice as much as the J&S but could be moved with two fingers.
Cross feed backlash is around 0.050"
It's smooth and not lumpy or crunchy but wow...I'm going to have muscles in my shit running this machine...is this normal for a J&S 540?
(this is after the hydraulics have run for a while...I'm aware these machines use hydraulic oil to lube the slides)
2) The cross feed ratchet is noisy; and when I reach in under the travel increment adjusting cover to feel the ratchet wheel, it's bone dry.
Would it benefit from some grease?
(the power downfeed ratchet is nice and quiet by comparison)
3) The machine is leaky...I'm told they're all like this...is this true?
It's not a lot...but when I commissioned the machine I noticed Kitty Litter in the bolt holes of the base (the ones you use to bolt the machine to the floor) and I typically have a half a teaspoon sized puddle on the floor after the weekend.
So please let me know your experiences.
Other than those minor disappointments, it's an awfully nice grinder, and it is in awfully nice shape for a 50 year old machine.
Cheers
