Chainsaw grinder questions, tips, tricks, and pics!!!!

[mrxlh]

I am not a fan of the CBN wheels. I know that makes me an outlier.

I did not like the finish I got with $100 wheels off Amazon. I could still overheat a cutter, if not careful.

I don’t have a problem with good quality vitrified wheels, *** as long as they are regularly dressed *** (lightly, once per loop).

I can shape them for custom profiles. I can get them for $15 each (or free from guys who buy CBN wheels!).

They do produce more dust, but I try to grind outside.

Some guys report better results with better brands of CBN wheels, but not likely the cheapest ones.

The shelf standard offering CBN might not be your best option, Baltic abrasives will make any wheel profile/material/grit you specify. That said, chain damage and how you prep the chain affect results greatly. I have had very good success with the standard CBN offering wheels. I do have enough loops as well as a great way to clean them that I never have to push a chain where it is dull enough that I need to take big swipes and risk burning a cutter. If I rock it, I just fast grind each side 2-3X to get it even without burning a cutter.

This is the way

Here is a grinder I’ve never seen before. Picked it up locally…anyone know anything about it? Says model number 22…an internet search doesn’t pull up anything I can find

Very cool!

Does not look exactly the same, but patent number matches, so they must be related.

Note the patent describes a device for sharpening both circular saw blades and saw chains.

Yours may be a later model?

I was wondering if it was a nielsen/bell. I did see some circular blade sharpeners that were similar, but not the same.

It’s different, that’s foe show!

I did some 33rs and Oregon at 30/55/0. I'll try and get pictures up tomorrow and see what you all think could use improvement.

What saw is that chain on? Or, do you run those measurements on all chains for all sized saws?

A 462 that went by Randy's place. I'll try to get pictures and see how they cut tomorrow. Just figured I'd try no top plate angle on both and see how they do.

I run 25/55/5, from someone's recommendation in this thread maybe, and have been really happy with those measurements. That's for my bigger saws. A bit less angle on that top plate really seems to help with longevity.

My top handles I run a 30/55/5, and that seems to work good on those.

That whole ten degree tilt thing is kinda like mix oil. Lots of discussion without any conclusions. Not an option on my grinder, so it's a whiff for me. Yay!
