How much modification was needed? I widened the rear slots slightly so the guide would slip down over the rivet but I did not change the depth of the slots. I thought that might be necessary, but on the initial use on a 'near-worn-out' chain, the file dropped into position about exactly as my hand-filing up to that point. I found my hand filing had a slightly different profile right to left that was 'corrected' using the rolling guide. I found that the file could be used easily with one hand while the other holds the guide. When free-hand filing, I use both hands on the file to try to keep angle, depth, and pressure the same for each tooth. With the rolling guide, the rollers seemed to handle the variables quite well. But the jury is still out, as I have tried many a 'guide' only to go back to free-hand filing as the preferred way for quickness and results.
Snowing now, so will plow instead of cut a tree down this am.
Oh, the Husky dealer had this guide, but seemed to have had them for a loooong time, as they were on stock that was pretty faded, and they had 'no idea' how to use them or if they even worked. For $8.42, I decided time to find out.
