Yep, always drop a file size.  More like the last quarter than the half way though. 

 

I been known to drop to as low as an 020  file on a 3/8 chain before 

Done this also . Tight wads we are ! not binning this chain till at least 5 cutters break off ! ?

Been doing that for years if I happen to have the slightly smaller file but its not critical . Certainly not " advanced " ! [emoji3]

We can get onto "very advanced"
(Hooking,square cut etc)
Later mate.[emoji12]
If stihlGB technical have to contact head office in Germany for advice, I'd say it's advanced for most.

That’s when the chain is cutting at its best!

No . Stihl GB are just young . ? Don't forget if you square file a full chiz its done from the outside in rather than from the inside out as pr round ground full chiz

Also when you get to the dropping down a file size stage its worth taking the gullets out as well with an 020 size file .

Whys that please stubby?

I’ve been doing it inside out with good results

Here's somthing else from a Carlton manual I have.

just chucking it out, as we’re talking dropping file sizes, what about depth gauges.

Ok . If that works for you its all good . To be honest I have not done a lot of it ( despite what people may think ) . I wanted to try it and when I researched it that was the recommended way .

That is for the same reason the top plate drops down as you file back down the slope  sooo the rakers need to be 1/5th of the file diameter below the top plate so it will be more as the top plate becomes lower .
