Nice to have when needed

Plan on using it to help balance lawn mower blades.

I have these on standby to turn regular 1/2 bits into pattern/ flush trim bits.

Saved several bits. Had them sharpened and with new bearings better than new.

I mounted this horizontally on some shelving next to my bench grinder. I just drilled a hole slightly smaller than the shaft and then hammered it in. I use it to balance lawn mower blades while sharpening them. It just happens to have a bearing that fits the center hole on my Craftsman lawnmower perfectly. I trust this way more than those cheap balancers that have the blade rest flat on top of it. Those you have to eye ball level. Theyre probably good enough, but this thing doesnt leave much room for error. Either it rotates left or right and needs more metal removed, or it doesnt rotate and its balanced. I got the idea from seeing those ridiculously expensive wall mounted balancers and then going on youtube to see if there was a DIY version. Sure enough, some guy had a video using this item. Im sure you could fabricate some sort of magnet to keep the blade from falling off like the expensive ones, but Ive never had my blade fall off. The bearings are wide enough that the entire width of the blade is in contact with it. I only put it up there for a couple seconds, take it off and grind and then re-check until it doesnt move. The blade is never left there where it could be accidentally bumped off, I dont have anything I care about under it and I keep my hands close so i can grab it in the center, if for some reason it did pop off. Those magnets are pretty cool though. ;) Hope that helps you.

Used bearings in the construction of mower blade balancer. Worked well for the project.

These perform well enough for me. I use them for routing binding channel for guitars where even little mistakes are not acceptable. They work in that situation just fine.
