Default Anyone have ideas on a home made reel type lawn mower sharpener?

I'd like to achieve a little hollow ground effect. On the mower would be nice.

Head over to the groundskeepers shack at the local golf course with a six pack or some other suitable bribe. They are totally setup to sharpen reels and know how to do it right.

It’s like trying to sharpen an endmill, but on a large scale. I’ve seen them done once at a golf course years ago, it was a large, purpose built grinder in a cabinet.

They took the reel off and mounted it in the grinder.

I'm pretty sure you are tight about that but here in the Sewer by the Sea they keep everything including the personnel behind locked gates. I can't speak Spanish either so it would be point at this and gesture about that.

I was actually thinking of doing this for others knowing that reel mowers are dinosaurs. I used to at one time own a Trimmer but I don't have enough lawn to back it up and turn it every pass (not that many). We frown on lawns here because of the lack of water. Water is still cheap, but more than almost anywhere else.

My dad had a Porter Cable portable planer at one time. The sharpener in the video could be scaled up with quite a bit of effort. I don't think you could do it on the machine unless you had some kind of cam follower and then you'd miss/lose one end or the other.

Thanks for that video! The PC planer was the best but the spiral cutter was expensive to replace. I've never seen the sharpening attachment and I've been a carpenter for 50 years. Used PC planers sell for what they sold for new around here. With a good cutter you can't get a better finish on a door edge.

I still have the attachment in my shop. I don't recall when Dad sold the planer and he's no longer with us to ask where the grinding wheel and other accessories went.

My 2 cents is that you need to build an attachment that would bolt to the height roller mounts. It would have two rods that would slide through a block mount. This mount could slide left and right on the rods, and a cutter or grinder could mount on this block. Very similar to a silage chopper sharpener.

Now, if the reel is power driven, you mount a carbide cutter on the mount pad and slide it across and clip the high spots, then advance the bit.

Or if it is a hand job, then a die grinder would be used instead of the carbide.
Probably this explanation is confusing as hell, but I can draw it if you need it or are interested.

But the bottom line is that the sharpening device has to be held at a standard distance right across the reel. To do the bar you would have to have a sharpener that could hold it in a fixed position, or have it clamped onto a mill table to sharpen with a milling cutter.

That's s pretty complex mechanism. No wonder I seldom see reel-type mower anymore.
