Has anyone ever actually seen it done? Was it a surface grinder, or maybe a water cooled mill?
How are blades sharpened?

Sorry,
Should have said chipper blades/knives. That's an interesting looking machine, it's kinda the same as a surface grinder but the head moves instead of the bed. I think you could probably do just as good with a surface grinder, and I see them come up for under $1000 sometimes. I'm thinking you could fabricate some kind of holder pretty easily to get the angle right.
I was thinking of doing my own blades, and maybe do some for local companies at the same time. It's not that time consuming, setup a couple blades, then go sharpen some saws, come back and flip the blades, go do something else. You could leave a set and go off to work, or leave a set and go to bed. Doing a few sets for other guys would bring down the cost of running the machine. Every dollar counts!

company i worked for had a small but ok machine set up and did the knives for crews all over the state.
Problem was I'd send up a real nice set but get sent back a worn out hacked set, so I stopped usin the servcie
You could do ok on selling the service but check how much and how long the abrasive wheels are as high wear n cost may chew into profits.
What you pay now for a set? My little bandit 65 2 knife set gits done for only $22 both knifes both sides hard to beat

Dont cry, just do it
Just make sure you have cooling fluid running over them while you are grinding or they will lose there temper.

I can totally relate to that. I lose my temper without cooling fluid too!
I haven't get a chipper yet, but have been looking around the last month. Going to look at a couple more on the weekend and hoping to buy before christmas. One big present sitting under a tree. It'll probably be a mid 90's bandit 250XP, 4 double sided 7 1/4" knives. Talking ot buddies they seem to be paying all different prices, and depends on how bad the knives are. Average price seems to be about $80 with weekly blade changes. That adds up to about $5k/year by the time you include some bolts. That's money I wouldn't mind keeping in my pocket.

Growing up my family owned a tool grinding business. I worked as a tool cutter/grinder for years as a youth. We made precision tools. Sharpening a chipper blade would be a piece of cake.
I always had the feeling they dont use the best steel for the job in chipper blades. I think they're using just high carbon steel, a better grade of tool steel, maybe with some cobalt would cost more but last a lot longer between sharpenings.
Maybe even Carbide inserts using the old blades for holders. Grinding out a groove and putting a set screw in to hold the carbide. That would keep costs down.

Weekly blade change? I never heard of anyone changing their blades weekly. I might change mine every 3 to 4 months.
I would feed myself into my chipper if I had to sharpen it weekly
I have a hansa blade sharpener, works really well, but since you dont do it wet you have to be careful about keeping the blades at a reasonable temp. Does our big and small chipper blades.
