Chain sharpening difference?

[airbiscuit]

The roller one used to be my favorite file guide.

The shorter the cutter, the narrower the kerf.

May I ask what you use for a file guide? Years ago I was at a hardwood log bucking seminar and heard several logging contractors talking about sharpening. This is what they recommended...View attachment 2707787

I use it every few sharpenings, but in the woods have the old clip on file guide.

I started out using the clip on guide. It worked well enough, particularly when used in conjunction with a progressive depth gauge tool. I still keep it around nd use it occasionally.

Some years ago, I switched to the roller guide like what you pictured. Works well, and I can see what is going on as I sharpen. It's handy that it has a progressive depth gauge built in.

My old MS250 became a better performer with a little muffler surgery. It's old enough to where it has an adjustable carb, though I modified the muffler long enough ago that I don't remember if I had to adjust the carb or not. I use Oregon chain and an Oregon grinder. I'd have to look what chains I ordered, but opted for a slightly more aggressive profile. Filing chain might be good therapy for some, but not for me.

Even my ancient Stihl 028 (I bought it new in the late 60's) benefitted from a muff mod. Stihl likes to restrict their muffs even back then and even more today.

I grind a lot of chains but I charge for it.

Huh???

I’m the OP and I’m wondering if the chain on my pro saw just gets used harder. It has a bigger fuel tank and I use it on bigger wood so I may just need to hit it one or two strokes more with the file.

I'd guess since you use it more and probably in larger or harder woods, you are heating your loop up more and causing more wear that way than on your 250.
Your 261 might rev higher than the 150, adding more to its heat

Huh???

It works that way if you pay attention enough to chain on how cutter is made.

Why you think we take chain back to back rivet before making goooood chains.

Agreed. If you look down on the top of the chain, you'll see that the cutter tapers to a narrower width toward the back. As you file back to that point that narrower cutter width means a narrower kerf.

Just take a bit of practice with ginger to get your chains good and sharp! You can also change the degree of rake on cutting teeth to suit your needs. The HF unit doesn't compare to the Oregon unit, but the price and taking time to adjust properly sure make it worth the effort!

I have had the HF chain sharpener for a few years. It seems to do a really good job. My saws don't complain about it.
