How do you sharpen your bandsaw blades?

[Woodworks]

I made up up a simple grinder system in the end. The CBN wheel arrived today and is fantastic. The profile is perfect for the Ripper blades and grinds effortlessly. Takes about 5-10mins to sharpen a blade so in the end well worth the effort and expense

Got fed up sending blades away for sharpening and being charged almost as much for the postage as for the sharpening.  Bought the Woodmizer sharpener and a setter and just don't need to think about how many blades I've got for whatever orders are on the books.
Normally it's 3 sharpens to one set, unless the blades been blunted with a deep embedded stone.........then it's sharpened and set

That looks fantastic. Excuse my ignorance, I’m new to bandsaws, but could you please describe the routine for using a chainsaw grinder with that wheel? How does the jig etc work, do you do all the left teeth then adjust for the right etc?

I got idea from this. Only available in 120volts though and pricy!

What setting tool is everyone using? Can I use the Woodland Mills setter for Ripper blades?

Just be aware that CBN wheels are much wider and heavier (had to add some bungy cord to stop it dropping) than standard chainsaw grinder wheels.  In that video you can see they have put a collet over the shaft presumably to avoid it fouling on the housing. I had to file a little bit off mine to get the CBN wheel to fit.

 

Something that I did on mine and have seen on other home made sharpeners is having the blade forwarding arm pushing against the actual tooth that is about to be sharpened. The tooth spacing either side of the weld can vary so you can mess up a few teeth if the guide is either side of the tooth thats about to be ground. 

 

Hope that makes sense

 

 

PS one more thing the there are no off the shelf CBN wheels that fit these grinders that I am aware of. I got one from Baltic Abrasives who drilled one out to the right size for no extra cost

I prefer your indexing system, nice.

 

Baltic Abrasives did my CBN chainsaw wheels, I'll get a wheel off them to suit the ripper. I have a lathe, so fitment no problems.
