Blade Sharpening Jig...

I have not made any contributions to this site since I am still acquiring knowledge from all of you and I thank you all for that.

I built a contraption to sharpen my blades for my angle grinder and I think it works extremely well. I mow about 35 per week and do some crappy commercials props so sharpening a few times a week is a must. This little jig has been the bomb since its inception a week months ago.

It cost me 4.00$ but I already had the plywood and the grinder.

It could be made with a circular saw, a drill and some drill bits.

Any feedback would be greatly appreciated, if anyone wants more info just let me know...I would be happy to share.

Looks pretty cool, I have thought about trying to do the same thing. I would rather give something like this a try before forking out a ton of money on a dedicated grinder. How well does it work and what angle do you have it set at?

Well, I took an adjustable angle finder and locked in the angle, I took it to my table saw and set the angle on my miter gauge and cut some exact pieces to match that angle.

I think it works great. The blades get razor sharp in about a min per blade. 3 swipes down the grinder wheel and good to go. Much more fail safe than free hand grinding.

Best of luck,

Grub

That looks simple and workable. I will be building one of these. Can you take a detail pic of how the grinder is attached?
Thanks for posting this.

blade sharpener

I'll be building one this weekend design looks great thanks for the idea. Did you think about hinging either the grinder or plate or make the plate removable to make changing the grinder wheel more accessible. harbor freight or northern both have these grinders for under 20$ they will last more than a year under hard use I have a few so I don't have to switch heads from grinder to wire brush,flap wheel saves a lot of time when working because you usually use both. has anyone found a more aggressive grinding wheel than what in normally available in most stores?

I will upload a few more detailed photos later. The guide for the blades is just screwed to the base so it can be removed to replace the grinding wheels.

Best of luck, I hope you have the same successes that I have achieved with this jig.

What a good idea. Can you email the dimensions of the 2 blocks holding the angle piece, the dimensions of the angle piece, and how tall is it overall?
