Grinder Control Question

Yeah I figured it would definitely need to be modified. I purchased it mainly cause I figured the wheels were worth 28 bucks if nothing else.

I think your mostly right about it's original life although the handle leads me to believe it may have been manually actuated instead of pneumatic. I'll have to take a closer look.

After looking at the pic's again,you have all the parts to make a good horizontal grinder.You would need a piece of plate to mount it all on and a con troller.But you got way more than 28 bucks worth of parts.

That's exactly what I was thinking
 
Where would he put the platen? There is only inches between the wheels.
I agree all the parts are there, but it would require tearing it apart and building one from scratch...which I don't think he has the equipment or skills to do. It also would run a good amount of money.
 
A couple of photos and a short video with the guard/dust collector removed.

Its a 2 X something belt.

Oh and Stacy you were absolutely right it looks like an actuator type screw is driven to push it side to side as well.

Sterling-
Are you sure about that motor? A 2.5HP motor running on 110VAC will be drawing a huge load. It will require 8 gauge wiring and 30-40 amp breakers. I calculate the draw at between 23 and 32 amps, depending on the motor efficiency.

Stacy, your right about that I just missed typed didn't mean to put the two in there, my grinder runs on a 1/2 horse and grinds just fine.

Yes, a 1/4HP motor on 110VAC is no problem...about 3 amps.

Ryanol;
OK, that helps.
Unmount the grinder from the forward slide and keep all that sliding and feed hardware for some neat future project ( or ship the slide/feed to me and I'll build something with it).
Mount the grinder plate on a work table with the motor downward.
Place a platen behind the upper part of the belt . The platen can be made from a piece of 3"X1/4" angle iron. Drill holes and tap them in angle iron, and mount from the plate side with bolts. Make the holes in the mounting plate slotted to allow adjustment of the platen. A pyroceram face would be a good idea,too.
Mount a 3/4" thick by 6" wide by 12" long piece of steel on the mounting plate in front of the belt. Use hand wheels ( bolts with knobs) and slotted holes from below to move this plate in and out so you can change belts and adjust the belt clearance.

This modification will make a low power horizontal grinder that will do sanding on scales and such. At .19HP it will stall if any real pressure is applied to the belt, though, so you will have to change the motor to do much with it.

The motor looks like a "C" face, so hopefully that can be changed fairly easily. You can change it to a 3/4HP 3Ph and a VFD controller for about $250-300 plus about $50-100 for the above modification....or buy an entry level 2X72 knife making grinder for about that.

Its a shame you live so far away, I might be willing to set you up with a motor and controller in a trade for that rig. There are some possible applications for it as is.
 
Here's what I am thinking in my head

Whether or not I could build it with angle iron, drill press, some taps and an angle grinder remains to be seen. Then replace the motor with a simple 3/4 1 horsepower 110 number. I'd rather keep it in the garage and not have to dig a trench for the conduit to run 220 if possible

Obviously I need to take some measurements and try and wrap my head around geometry to make sure it would all fit but what do you think?
