Home made sharpener pics

[cat man]

These are pics of a sharpener I just built. All of the parts were hand built with welding machine,drill press and hand tools. A neighbor wanted me to look at a store bought sharpener he had.After I seen how it worked I thought I could build It.This thing works great 8) Enjoy

Cat Man, I am impressed with the sharpener.  I have been trying to get back on the one I started but haven't gotten to.  You and I live near each other.  I'll send you a pm.

Very impressive. I love seeing someone conquer a challenge. Have you used it enough to know all the kinks are out?
I didn't realize you 'posed to sharpen the back of the tooth. Course I never even seen one of these things in action Menominee loves me so far.

Nice work and great picture details.. 

The only thing is I think the gulleys will need to have a little material removed to get rid of the small microscopic cracks...

Kevjay,

The whole tooth profile needs to be touched by the grinder.  The face needs sharpened to retain the square corners necessary for the cutting, the gullet needs touched to remove any accumulated stress cracks, and the back needs touched to maintain the profile of the tooth so it doesn't grow in height.  Lacking any of these may not hurt much in the short term, but over several sharpenings they add up.  Failure to grind enough away in the gullet will lead to band breakage.  Changing the height off the tooth changes the way it cuts too.

kevjay, yes I have worked out the kinks and now its ready for a coat of paint.

jerry-m & Minnesota_boy, I think you should dress up the gullett and tooth profile.With  a little more cam profile this sharpener should do it. This is just a start for now .With my hobby milling if  I can get three or four sharpenings before breakage I will be happy.

highpockets, I will check your pm

Everyone Thanks For The Comments

That's a pretty neat setup you have.  How do you get the face with your sharpener?  I've sharpened probably thousands of blades by now.  Done them all sorts of ways for customers.  Face only, face and top of back not touching the gullet, face down all the way through the gullet and up the back.  Depending on what kind of grinding stone we're using and what kind of burr is being left is how we do it.  Since we'll sharpen any manufacturer of blade the gullets are all sometimes a little different and we only have so many cam's.  One thing I've found is the gullet isn't as important as you may think to keep a full edge on.  Yes it's important, and if you get too much of a radius then dust spill becomes a problem, but the main point is to make sure the face is good and sharp with no radius and the set in the teeth are proper based on the type of wood your cutting and frozen or non frozen wood.
