I recently purchased a 16in Gould & Eberhardt universal tool room shaper from a fellow member on this site. I wanted to change the oil in the sump before I started running the shaper but got somewhat confused when deciding what oil to use. The manuals I found online (http://vintagemachinery.org/pubs/2111/19571.pdf) recommended oil with a viscosity rating of 450-600 saybolt units. When I checked the list of suggested oils I recognized Mobil DTE Extra Heavy as being a ISO 150 oil. I went to Mcmaster-Carr to order a 5 gallon pail of ISO 150 oil (McMaster-Carr) and noticed that it had a saybolt rating of 750.
At the local farm store I can get 5 gallons of ISO 100 trans hydraulic oil, but it has no ratings marked other than ISO 100. According to a viscosity chart I found online, (Viscosity versus viscosity index) 80w90 falls right in line with the correct viscosity ratings and the stuff currently in the machine smells like gear oil.
Does anyone have any experience or advise on what oil to use in this shaper.
As a side note I'm having issues getting the table to move vertically, it seems something may be jamming the bevel gears that appear to drive the nut on the screw. It looks like there is a access cover behind the horizontal screw but I can't get to the screw heads without removing the lead screw. If anyone has any suggestions I may have missed I would be happy to hear them.
