Howdy all! Anyone have leads on a good jig or set of tools to make Forstner sharpening a breeze? I have a set a honing cards and a triangular file I can do a fair job by hand, but after 5 or 6 sharpenings I can see that I'm rounding the edge and the point develops a slight wobble so I know I'm getting off center. I've searched around and haven't found any services to sharpen Forstner bits or guides or tools. I could just buy more, but I hate to just recycle the steel when it seems like there should be life left in it.

Is everyone just sharpening by hand? Thanks!

I use forstners mostly to drill the initial hole in hollow forms, mostly endgrain, so I abuse the heck out of them. I dont care so much about the precision of the them as how fast they cut. I present the cutting surface of the bit on the flat side of the grinding wheel on my grinder, and touch it just enough to freshen the edge, I will try and get a pic when I go out to the shop...

I lock them in a vice to keep them steady and go at it with a diamond file . Two hands on the file and hold it firmly.

Thanks! I'll keep looking. You'd think that in a big city like LA there would be more options. I've only found one shop that will handle my router bits and they don't do Forstner. There are 3 professional barber scissor and clippers sharpeners within 5 miles of me. I may reach out to them to see if they are interested. Plus I need a haircut. :ponder:

Yeah, I think you're right. Based on their pricing structure, I'm guess that most of their business is industrial. When you offer a price break at 25 or more 12'' saw blades, you're probably not very excited to see me stroll up with a dozen forstner bits in my pocket. :cowboy:
