lots of ideas and questions I've pondered myself are posted here.
dressing up a cutting edge, most times is just to remake the bevel and remove round over, from the continued honing... that occurs normally,
If a feller or gal wanted a portable tool to grind a knife back into shape and power hone it while running on battery power?
this question has been posed many times here on the board.
f
rom my junkyard days spent as a youth, the first thing that comes to mind is a heater or air conditioner motor for the same vehicle voltage,
cars trucks and them big rv's are not the same voltage, so before running out and buying a fan motor check your rv's voltage it could be 12 VDC or 24 VDC,,
tell the attendant you need the wiring color code intact and the switch if its obtainable, or go to a u pull it junk auto salvage yard and get it yourself for $10.00 or so. if you got the tools
take the motor to a machine shop and get them to thread the output shaft('s) to whatever you need,
the shaft may have to be adapted to make it bigger to fit the wheel, with a shaft arbor, the machinest can make. or just make a home made wheel to fit the shaft, use the heavy fender washers to strengthen the binding force of the shaft nuts and on the shaft that tightens the wheel(s) and use rubber glue on the shaft under the wheel to shaft connection this will aid in a non slip connection. and help lock the nuts in place
most air conditioner motors are double shafted, (a shaft on each end,)
they can be threaded, left and right so the direction of rotation will aid to tighten the nuts,
these are low amperage motors and they wont last forever, they wont take a really big load but you don't want to hog off that much steel when your doing touch ups, so it should be ideal. for a quick fix on a dropped tool or just reconditioning a rounded over edge.
build your rests out of wood and label them as to what they are for,
another nice thing about using vehicle fan motors is they are multi speed. and should be readily available at a auto wrecking yard.
switches and such should be available from there as well or an auto parts store. wiring can be researched from a repair manual for the vehicle it come out of...
WET GRINDERS.
the small delta or task force wet grinders are great for touch ups at home, hard to wear down a straight razor, to a carvibg knife with though, Although great for touch ups i found my small delta wet grinder wheel getting out of round, and there is not any replacement parts, for them there designed as toss outs after the wheel gets too bad.
Harbor freight tools:
has 2 wet grinders now in stock, the 35098 for 59.00 i own this one and i don't like that it has a plastic gear that turns the wet wheel i returned it and bought the extended warranty for $10.00,
as it was replaced with a new unit, im going to use this baby up making razor knives,
this unit has no rest on the vertical wet wheel. its nor reversible. the other wheel a dry 3/4" x 6" 3350 rpm has a rest like most bench grinders, i would say its not a good choice even at 60.00bucks.
HFT: also has another model looks like a tormex, with all the different rod based tool rests and some jigs im looking at, its at

but at $100.00 , its a 150 rpm 8" wet/dry wheel with a hone built on..
but lets all face it, us as carvers are just looking at it as a conveniences to get the drudgery of sharpening over quicker, but a real sharpening of our single most used tool probably shouldn't be done but once a month in most cases, we tend to wear out our tools prematurely due to over sharpening, when honing or a touch of a Arkansas stone would be better touch,,
