With this jig you can sharpen all chain used on hand held chainsaws. Jig-filing can achieve the sharpest possible chain--equal to that of a good grinder--and much longer chain life than can generally be achieved with a grinder. You can work in the field with a stump vice or free-hand with one hand holding the bar, filing with the other hand, and steadying the power head with your feet.
1) Flat-filed, chisel chain is universally recognized by experts as the fastest cutting chain. I will show you how to sharpen this type of chain on the Granberg jig as well as the other types of chain.
2) How to file in a comfortable sitting position so you can file during little breaks.
3) Simple changes to the jig to improve accuracy and speed.
4) Setting the depth gauges with the Granberg jig.
Why the Granberg jig?
In contrast to the Oregon jig which is very flimsy because of a plastic filing frame, thin wall construction, and difficult to read black-on-black dials and a red-on-red dial; the Granberg jig is very solidly built with all-metal construction, thick sidewalls, and easy to read dials. I started off with the Oregon jig, but then gave the Granberg jig a try, was delighted, and never used the Oregon jig again. The Granberg jig provides a complete solution for all chain used on hand held saws.
The ATOP file guide is a specialized tool for flat-filed chisel chain. Too expensive at about $200 and not as good as the Granberg jig for flat-filing.Read more ›
As noted, the instructions for these file guides are poor. Some of the YouTube instructional videos are better. But if you can figure them out you will get very good quality sharpening results at a fraction of the cost for a good quality grinder.
These guides are relatively slow to use, but are a good option for someone with a few chains to sharpen periodically, is methodical, and has some time. They use commonly available and inexpensive files, and work on almost all types of chains.
I was disappointed in the quality and finish of this Granberg model. I had to disassemble it and file, grind, or buff each cast piece, and even the thumb screws, to remove sharp edges. It may have more metal than some other models, but it feels cheaply made.
I eyeball the file so that 1/5th of the file is above the top plate, per manufacturer's instructions, so the different increments in screw threads between the brands is not an issue with me. I don't use these guides for setting the depth gauges ('rakers') - this is just too easy to do free-hand using a simple depth gauge tool and file, which also lets me round over the leading edge of the depth gauge, per instructions.
A couple of tips:
- Use good quality, sharp files. If your file is not cutting, replace it - they do not last forever.
- You still need to stabilize your saw to keep it from moving when filing. Clamp the guide bar in a vise, if you have one.
- I have several chains for each saw, and do not want to mount each chain to sharpen. So, I clamp an extra guide bar into my bench vise and mount the file guide on that.
Sharpening freehand eventually leads to a sloppy chain. One of my saws is a Husky 575 and with the speed and torque on the chain I like it to run as smooth as possible.
The majority of time people using electric sharpeners take way to much off the chains and cut their life in half. With this setup you can ensure your outcome to be precise and well done even in the field.
I used to run three chains, switching from one to the next instead of sharpening in the field. When I was done cutting I'd sharpen each chain at the end of the day. Now it takes a few minutes to sharpen them instead of changing them out and I'm ready to go again.
I would suggest a second screw(B)to secure to the bar better but it's okay the way it is.
Documentation! Way too concise! The provided instructions amount to about four paragraphs, replicated in three languages, on flip sides of a single sheet of letter-sized paper. There are a few small photographs, but with minimal captions.
To use this tool you first mount a round file of the correct size (for your chain) into the Granberg and tighten it into place with two thumb-screws. Pretty simple to do! Next you mount the assembly on the saw's bar, with the main body of the assembly parallel to the upper edge of the bar. To do this you position and tighten a small pair of jaws over the center of the rivets of the chain you are about to sharpen. You then make sure the Granberg's main assembly body is parallel to the upper edge of the bar, then you securely tighten a thumbwheel toward the nose-end of the saw bar. Then you back off on the jaws enough that the chain will slide through them. IMPORTANT! There is a vertical-axis leaf spring on the assembly that is a stop, and is there to hold each tooth of the chain in position for sharpening. In order to move the chain you must swing/pivot the arm holding the file upward adequately for the leaf spring to clear the teeth.Read more ›
