Cincinnati No 2 Cutter Grinder Restoration

That is a bummer. Mine is a 240 three phase. My cutter/grinder came from a small sharpening shop near Brantford so perhaps the motor had been changed? Since you need a new motor you can just go with a 120 or 220 single phase as the grinder should only run in one direction and the belt rail offers 2 speeds.
 
I have a pdf of the manual and several other manuals on the tools. If you PM me with your emails I can set you up. I should be up and running mine in a few weeks. Sorting out the shop has taken quite a bit of time and the sharpener took a bit of a back seat.
 
Thanks Brent, the easiest suitable motor to source here is a 3 phase. All the single phase ones that I could find are only 1400 rpm unless I go 2HP or bigger. We have a very small market in Australia so our choices are always limited.

Hi Brent, thanks for the offer. I had to look on line what a #2 tool sharpener looked like, only to realize that I have #1. Apparently these being smaller were often purchased for school training purposes and I
the fellow that I purchased it from picked them up from Barton High School on the Hamilton Mountain. With that in mind I started looking for the manual that it came with and found it in a filing cabinet at home.

I took pictures, see below. Judging by the condition, I don't think anyone ever looked at them as there is not a dirty finger print to be found. The sharping instruction, well that is a different matter.

Hi Brent,

Still a couple of weeks before I get the Cincinnati delivered, but I did grab all the loose accessories and brought them home. The work head was in pretty bad shape and wasn’t rotating very well. I stripped it down enough to give it clean and noticed there wasn’t any grease in the bearings (not even old dried grease). There was a fair bit of grinding dust inside. I’m not sure if you have had yours apart or not, but do you know if yours has grease? Interestingly, the bearings were engraved with the date I assume they installed in 1949.

Here is a few shots of my #1 with some tooling that it came with. I don't have a set of centres for it. There is also an electro magnet surface plate for it I forgot about. I managed to find a vintage 600 volt twist lock cord cap set and install it so that I could move the work head motor away from the machine. I will say the worst part of a tool grinder is the amount of grit and grindings it spreads over the machine. The work head uses 5C collets and also there is a MT #4 3 jaw chuck with both inside and outside jaws. My machine is 600 volt 3 phase and uses a 240 volt to 600 volt roto phase converter. Built on electrical theory it self starts with the use of a 1/4 HP motor that drives the monster 5 HP motor sitting on the floor. That motor I found at Triple M Demolition that had been rewound bolted to a skid for $50. When turned on the 1/4HP motor runs up the main 5HP motor by way of a drive belt and pulley. After 5 seconds a timer disengages the 1/4HP run up motor and a contactor closes putting 240 volts across the low voltage winding of the 7.5KVA transformer and now produces 600 volts single phase that goes across 2 of the 3 wires of the 600 volt roto phase motor that is sitting on the floor. The 3 terminals of the roto phase motor are now producing 600 volt 3 phase power to run the grinder head motor and the work head motor. Commercial units normally use a 208 volt 3 phase motor and then use a 208/600 volt 3 phase step up transformer to now produce 600 volt 3 phase power. The single phase transformer is cheaper and easier to find used than a 3 phase unit. I found that too at the Triple M yard for $50. I built this unit in 1992 and never had issue with it working. I have not used the machine in years and it really needs a good cleaning and some paint. Hmmm, I am retired, I will put that on the to do list.

@JohnH - yes, I took the work head all apart and then some. I had to weld the base all back together and I have mine filled with oil, not grease. Spins very easy. Mine is a 50 taper and I have a number of adapters- the main one is an OZ 32 collet set. Also other adapters for saw wheels and other cutters.
