Gentlemen,
For those who have a Brown and Sharpe No 13 Universal and Tool Grinder prior to 1952 that uses oil cups and drives the spindle using a flat belt powered by the motor in the base (i.e. before they changed over to ball bearings, gear driven table feed selector, pump-driven lubrication, and spindle powered by an adjacent motor). Your machine should ideally look exactly like this (as close to 1943 as possible):
I wish to convert this machine BACK to a flat-belt-driven spindle but the pulleys (and tensioner?) upon which this belt rides have been removed. I have some or possibly all of them in a box that came with the machine, but lacking any kind of documentation for this model, I don't know what is needed inside the base. I have one pulley that rides on an oil-cup lubed journal extending from a flange with three screw holes, and the side of the machine still has the fasteners in the hole in the casting from where I believe this pulley was removed. Beside that, there is another hole in the casting where likely another pully goes, but I don't know what that one should look like.
If you would please, could you take a photo of the pulley arrangement inside the base of your machine so I can piece back together the belt-drive mechanism? Also, one parts manual I believe described the belt as 1-1/4 wide and 118" long;
Does this single belt loop around the motor and up through the column using two pulleys to guide the belt basically at right angles from the motor up through the column? How does the belt remained tensioned as the spindle rides up and down on the column?
Thank you for your help.
