Chain saw sharpening advice sought

[beowulf]

I always thought a battery chargers had to be hooked to a battery to be able to power something or it might burn out a 12 volt motor, CB, radio, tape deck....

HMMM? I guess I need to check this out before I make a mistake. Maybe I will contact Grandberg and ask.

I would think filing on a harden steel plate will dull the file quicker.

I have one for 3/8 chain. I use it to check the depths of the rakers, not actually to leave in place while filing.

Don't know about using it for electronics but I've used one before to power bilge pumps.

scdeerslayer, I have sent an email to Grandberg to ask if their 12V grinder/sharpener can be operated safely from a battery charger.

I guess it would not be terribly inconvenient to pull the pick up into the shop and hook it up to the pick up battery whenever I need to use the sharpener as it will not be something I will likely be doing very often, but it would be nice to be able to use one of my old but functional battery chargers. I will post any information I receive from Grandberg on this thread.

Wow! That was fast. I had just sent Grandberg an email re using a battery charger and they replied immediately.

Anyway, this is the response from Grandberg:

"Yes, you can use your battery charger to run the unit. It draws about 4 amps at full power, but you can use a higher amperage setting without a problem. "

Kudos to Grandberg for their immediate response - great customer service.

For years I touched up my chains in the field by hand with an Oregon guide and file. Then a thought , and I took my DeWalt cordless drill motor, the file and guide with me. Chuck the file in the chuck and use the guide to determine the angle. Pull the drill trigger while applying horizontal pressure and 5 seconds later that cutter is sharp with a rotary file. Do each cutter the same 5 seconds with the same pressure. The rotary file keeps a lot better profile than stones that are soft enough to be effective grinding.

Chain saws weren't introduced for wood but as a medical instrument - bone saw.

First I've heard of that, but I have heard a story that the guy who invented the tooth shape for chain saws was inspired by the mouth of a wood beetle that he saw while logging.

Inspired by this thread, I went looking for some diamond Dremel chainsaw cutters. I was happy that these were so inexpensive. They come in all the usual diameters. I'll post back regarding their quality the next time Pa digs his saw into the rocks. For the price, I'm not really expecting much.

Thanks for chasing that rabbit down, now we all know, or atleast I know.

Yes thanks for that post, let us know how they work, I haven't tried those kind.

I posted this some time back. It might help you some.

Get the right size file for your chain and drill a small hole in a golf ball - one that the sharp end of the file will stick into. Tap the the ball onto the end of the file and you got an instant handle that will work perfectly. Don't drill the hole too big. Clamp the bar tightly in a bench vise (make sure the vice doesn't keep the chain from rolling) Using the kickback for a brake file each tooth and then take the brake off and advance the chain to file the next section of chain. Make sure the chain is fairly tight on the bar and file each tooth using a motion that pushes and turns at the same time. DON'T use a sawing - back and forth motion- doesn't work very good that way. Try to maintain the angle that is already there and get in the habit of doing this often so that the chain doesn't get too mangled up. When you're done with that side take the saw out of the vice and do the other side. After some practice you'll be surprise how quick it is to touch up a chain. Remember too that the guys that use a machine are taking off more steel than you would using a file. Filing the chains gives more use since your not grinding off more than you need to.

I'll be looking for a diamond burr but i not putting it in my dremel that runs 20,000 rpm or whatever it is. I can't think of a faster way for me to screw up a chain. It'll be going in my variable speed drill because I'm just wanting to touch up those little teeth, not re-manufacture them.

That has always been my objection to using a machine of any sort. I had one that used stones many years ago when I used saws a lot on eucalypts in Australia and soon realised it was difficult not to take too much off.

Agree! I can re-sharpen many times but if I take it to the dealer I only get 6-8 sharpenings out of a chain.

 

[OldMcDonald]

Creamer, Do you buy your chains there?

 

[JRobyn]

Resharpening 6-8 times is probably 5-7 times more than many chainsaw users get!

I typically can't get that before mine find a nail or rock. I was once sawing up a 36" DBH red oak and my buddy burnt up two chains on his 2101 with 36" bar and I got one on my 7900 with 24" bar before we realised someone had filled a hollow with concrete somewhere down the line, that was an expensive day.

This thread got long quick, I do what I'm not supposed to and do it free hand with a cordless dremel tool, I take that in the woods with me, I have always sharpened my chains this way and am good at it now.

I have tried the files with guides, I have a guide for my dremel tool but I'm not a fan of any of it, I can get it sharper, faster by hand. With the amount I used to cut I was sharpening chains almost daily. Whether I sharpened them or took them to a local shop.

I guess I got tired of swapping chains and dropping them off. I haven't destroyed a chain yet and all my saws cut quick and are always sharp.

I also have 5 chainsaws right now I use, most in the 20in bar 3/8 chain and longest is 25in .404 chain on my 660 magnum

 

[TomSeller]

On the electric sharpeners has anyone made theirs so you can spin the wheel in either direction?

 

[Creamer]

Creamer, Do you buy your chains there?

That was one reason I learned to sharpen them. It took me a few years but I figured out their system. My excuse - I was a newbie to chainsaws and didn't know any different.
