My MKIII Power Sharpener

[Johnny Kleso]

This is my version of the LV MKII Power Sharpener..

I started this last year or so you can see what it looked like here
https://home.comcast.net/~rexmill/sh...III/MKIII.html (https://home.comcast.net/~rexmill/sharpening/MKIII/MKIII.html)

I have been using it with just the wooden sides and a plastic top for more than a year for flatten chisel and plane iron backs..

The plastic got to hot and would melt and grit would get down into motor and bearing area, so it needed a redesigned top..

I always had plans to wrap it in steel and after getting a good deal on some stainless steel I when with that..

Feet and handles where made on my 9" metal lathe..

In the next few days I will finish the design of a tool rest/holder and style it close to LVs and I will make four or five 8" platters to mount PSA sand platter to..

I added the feet and air vent as motor gets really hot and with no air gaps flattening a lot plane and chisel backs and worry I'll burn the motor up..

This type of machine excels at that flattening, I have not found any thing better..

The top got to hot and would meat and grit would get down into motor and bear area so it needed a redesigned top...

I wonder if putting a fan blade on the shaft inside would help with air movement to keep the motor cool.

I have the LV MKII power sharpener and like it a lot when there is a lot of work to do on a blade.

Hi Jim,
Great minds think a like :)
I has the same thought, but figuered I need to start with a few places for air to get in, before the wood box with no feet made it almost air tight when on a bench..

I also thought of a small box fan like computers use but for a 120v they are about $20

Not sure how much direction of air movement would effect the debris getting in to the box and motor. Maybe have it blow out the holes on the side and have a baffle at the bottom or a filter like those used in furnaces.

Just some thought.

Wow, the steel and handles really dress that up over the last version.

I am working on a painted plywood version myself, inspired by your design. I have an idea that I can use a piece of angle iron across the top of the platter that will allow for me to use my Veritas honing jigs. If I can get the angle iron set to a specific height then I can just offset the settings with the jig.

I will post pictures of it someday but it will never look as good as your current version.

If the bottom is open, then try using higher legs to encourage better air flow.
Nice looking job.:)

Scott,
I have some brass angle and just debugged a design I have been knocking around..

Eddie,
I hoping these feet a tall enough with vent holes, before it sat flat on a work bench and was pretty much a sealed box..

Thanks for your input
