Title: ATOP
Post by: Cut4fun . on February 26, 2011, 12:10:02 pm
Talking with Goran in emails and he might be interested in coming over here in a sub-forum to help you guys out and answer questions.

There has been some pretty quick chains I have seen come off the ATOP square guide for softwoods and good square work chains. This was done by another friend I know that bought one to try out.
He is using a different file then what comes supplied and likes the results he is getting.

Weird thing is we both use it different when watching each other file with the guide and get different angles. So it comes down to the user input too.

I wanted to try one of them out. I got a silvey swing arm now so I don't really need one. I still would like to try one out. It might be a good thing for someone who doesn't want to spend a chunk on a grinder.

Tried one and did not get good results. No doubt that over time I could make a chain work. Slow chains stay home.

Art something I noticed on the one the guy brought to the house. They are coming with 1 set of rollers and they are a different size then I used. Mine came with 3 sets of rollers straight from Sweden.

While sandusky was here we took a stock CL chain and then used his square atop filed chain and he was knocking off 3 tenths on his chain in softwood cuts.   We didnt write anything down so I cant get any deeper with info.
I do know he uses a different file and holds the file on the guide different then I do. So it seems a lot of factors come into play, just like user input on hand filing.
