Home Built Sharpener

[GF]

I would like to be able to sharpen my own bandsaw blades for my sawmill, does anyone have any good ideas or photos of sharpeners?    

[Jaws]

I built a blade sharpener last week and I am not try.
I built a guide and use a radial saw as grinder.
I post 2 pics.

Hey I've got one of those unused radial arms saws just takin' up space in the shop. Maybe I'll go into competition with the local chain sharpeners, they sure need some.  8) 8) 8) ;D

The commerical sharpeners operate with a cam that lifts the grinding head to maintain the tooth profile and tooth spacing. It also allows for grinding the face of the tooth, the back of the tooth, and the hook angle.

I was planning on milling a template that a camshaft is tied to, this would allow the blade to automatically feed using the camshaft and as it feeds it follows the the template that moves the sharpening head, this would allow the entire profile of blade to be sharpened.

GF: I'll try and remember to take a couple pics of my woodmizer sharpener when I get home tonight. That might give you a few ideas.

Jaws,

That is a good idea to use a radial arm saw.
If you do not already have one, a guard between you and that stone might be helpful. I have been sharpening blades since 1986 and have had one stone come apart. It happened when the grinder was turned on and was running up to speed. The stone separated and flew out. I was standing to the side and nothing happened except surprised that it happened. Now I always stand to the side when it is turned on. ;D
Good luck.

GL: Here's those pictures.

This is the cam (timberwolf) and tooth pusher. The cam lifts the grinding head and the rod pushes the tooth forward with each revolution.

This is the vise and the end of the tooth pusher

The bearing at the bottom follows the cam

So what I need then is a sliding miter saw?  ???
