Really nice set up. In particular you have the 'pusher' indexing the actual tooth to be ground. Many I have seen index the tooth before. If that tooth is somehow different in shape/size it will impact on the tooth to be ground. I am about to make one and will incorporate the method you use. Thanks for putting this out there.
You are observant. That is the reason I did it the way I did. I will day I have resharpened a lot of blades with this setup. It works very well. You just let it go, take your time and you'll have a nice new blade.
Congratulations for presenting a clear and useful view of your machine; one of the best for this kind of machine. l so noticed that it sharpens blade a bit differently and this is useful for my purposes Thanks
There is some good information on the internet on how to develop a cam you have to know first the geometry you're trying to copy which you can get off the saw blade and then there are slick easy ways to develop the cam. It consists of drawing some concentric evenly space circles and some radial even space lines and then connecting the points with a line called a spline which represents the geometry of the sawtooth that line then becomes your cam. I still made three before I got exactly what I wanted but the first one was close.
Looks great! Been kicking around the idea of building one to sharpen blade for my Woodmizer sawmill. I like the idea of using a tool post grinder for the spindle unit and building it all on a vertical plate. Using a full radius wheel like that would make it easy to find a CBN wheel to fit it too. I may have to steal your ideas.

@@woodintheworks3275 good luck on the build. Also you can find good info on how to generate the cam on the net. I then used a cnc machine to cut the shape

Can you tell me what model Themac grinder you used on the machine and what size spindle shaft it has? I'd like to find one that would accept a standard 1 1/4" wheel adapter but that might be difficult. I've been looking around at grinders but unless you get a really large one they mostly have pretty small spindle shafts. Thanks
Have you seen how much these things cost? I am making my own, not just because of cost but more to the point because of the satisfaction in the journey of the build and being able to watch your creation in action!

Everything this guy does is amazing.
Thanks. Your too kind. I like to do this sort of thing and share it in the hope that it helps our someone else.

Your welcome. Thanks for the comments
Beautiful, I love it when a plan comes together! Now I'm thinking about changing how I sharpen chainsaw chains! 😂
You could build a similar setup for chain saws. Would actually be a little less complicated.
This pink aluminum oxide grinding wheel looks good to sharp the bandsaw teeth, and this machine is fantastic.
Thanks. I use it often.
Awesome! You are quite the craftsman!
Tony Wadkins Thanks Tony it works well and save money on blades.
Good job how did you scale the cam for the grinding wheel up and down did you just play with it a bit or have a pattern??!!??

Home made but certainly well made!!!
Thanks

If I ever wanted a tank building you are the go to guy for sure, this should last you out and your great grandchildren too.
Thanks. It is fun to build stuff and then put it to use.
Hi, nice. What about if you need sharper a 10 teeth per inch band saw, that works? Thanks
I would have to make a new cam.
Shoot them sparks into a magnetic metal parts dish.
Awesome job
Thank you
Nice build! Where did you get your servo motor to run your cam at?
That motor is a dc right angle gear motor. I got it surplus. You can find them on the internet with the motor controller.
@@whistle3man ok thanks. I'm going to build me one and was wondering where to find those at

@@whistle3man ok thanks. I'll have to check that out

Very cool!
Thanks. It comes in handy.
You should be able to sell some plans for that. Will your current cam follower allow you to sharpen other blade profiles or just that one ?
that cam is for the lenox c sharp blade. other blades would require a different cam

D6c10K the model is a J45S. its OLD. i use a wheel from a chain saw sharpener. the grinder i bought many years ago ay an auction.
Man, that's awesome
Thanks
Buena
Do you have plans for your sharpener?
I'm sorry but I don't. I will be happy to answer any questions for you
Use WM CBN grinding wheel
Impressive.
Logjam5 thanks
that is bad ass. build me one.
Thomas Shue thanks. you will have to build your own. I'll answer any questions you have
Masterpiece :)
Ingvar Sigurdsson thank you!
Your a genius but I could buy for alot less than time and material you put in
I don't think so. I had all the materials and hardware for free from my surplus.
Have you seen how much these things cost? I am making my own, not just because of cost but more to the point because of the satisfaction in the journey of the build and being able to watch your creation in action!
Need to take more off on the face of the tooth.
Not a problem. I would just need to adjust blade position. That blade was junk so it was just a show and tell piece. Thanks for the comment.
Te machine is just!!!!.... and good.....................
The profil of the teeth is totaly wrong...... it need to change the cams!!!!!...
There's a lot of good information on producing cams on the internet how you lay them out etc.
