Hi all,

I picked up a Boyar Schultz 6-18 1953 Surface Grinder over the weekend. I found the sales brochure on vintagemachinery and it appears that the spindle is supposed to have an oiler and not a plug. Anyone have an idea on which type of oil dispenser I should seek out of this? I was thinking that a "
Oil Dispensers with Needle Valve" from McMaster might be the way to go.

Also does anyone have a manual for a Boyar Schultz 6-18 1953 Surface Grinder?

Thanks,
Ben

Is the spindle plain bearing or ball bearing?

Good question. I have not torn it down that far. The Sales info says "This Spindle is of improved design. It is engineered and built to use 8" x5/8" and 8"x3/4" wheels. This size is heavier than is usually recommended for this size Surface Grinder. The Spindle is equipped with pre-loaded superprecision bearings and operates at 3,000 R. P. M. Ample lubrication is provided; accurately ground spindle is perfectly balanced which accounts for the Grinder's smooth, quiet operation. Work is illuminated with two lamps." Not much help there.

pre-loaded superprecision bearings
Ball bearings. The oiling system may be set up from the factory for total loss oiling of the precision bearings, thus constantly purging the bearing wear byproducts and any other contaminants in the spindle housing. In a closed system, it gets dirtier and more gritty over time, even if it started out pristine clean. The drawing you posted also looks like a drip oiler, adjustable for flow and for on and off. If my thoughts are correct, the oiler needs to be filled with an adequate oil supply _of the correct oil per the user manual_ (very important). The oil also needs to be refilled before the oiler goes empty while running.

Of course, I am only guessing. You really should have the correct factory operation manual for this machine prior and have read it carefully before hooking the grinder up to power or actually running it. Do you have the model number for the machine?

Thanks for you thoughts Bob. If I had a factory manual I would have read it. I only have the information that I provided in the subject "Boyar Schultz 6-18 1953 Surface Grinder"

Look the machine over for a data plate or model and serial number stamping. Or anything else that might be useful...

Bump to see if anyone has anything to add. I was not able to locate a data plate or serial number. I have torn down the machine to remove the cylindrical way as they were quite dirty and causing poor movement. I found that they appear to be total loss oiling like the spindle. The oil ports on the way are open to the air. I am thinking that I will need to build some kind of drip tray as one has not been included.

I am thinking of running light spindle oil in the spindle and way oil on the table/head and "carriage" ways as I do on my vertical mill. Really I am wondering about the rate of oil that needs to be going in to the spindle. I will be purchasing a drip oilier, probably from ebay. And a few oil cups that are missing as well.

Missed your earlier post Ben. My Boyer Schultz is the early version that is belt driven, can't remember if I ever came up with a date. It has sealed bearings so no spindle oiler. It uses a drip oiler at the top to lube the vertical ways for the spindle and the thread. The linear ways have a cup with a reservoir that feeds them. I use way oil on all those points.
There is a can in the cabinet that catches the waste oil from the ways
Hope that helps.

Thanks Greg! Does yours look like this one? The drip oiler is in the spindle housing? If I take the back cover off this one it has oil cups on each side of the column that feed the vertical ways. I am guessing this may be different.

This one is driven by a flat belt as well.

Sorry Ben mine is different. Mine is a 6x12. The oil cup on mine is at the top of the column. I'd still check for sealed bearings on yours.
