Square filing chains

OK, time to get schooled ............ my chains are heading out tomorrow and there will be 3 of them. RS and RSL untouched and fresh off the roll as well as my feeble attempt at my first race chain. I aint too happy with the cutters (whats left of them I mean) but I cant stand the thought of making another due to the HUGE amount of time, files, and carbide burrs that I went through.

I might just spin in all new cutters when I get this back to save time

Anyhow, I have the addy and I will send Hedge a PM with the tracking ...................... oh yeah, that school thing ................ I am sitting in the first row, up front so I can learn !!!!

That pic above aint right Hedge ............... I aint scared, but that top plate edge is nothing to laugh at ............ what are you using - a 4 side goofy ??

 

I've learned more out of this thread than any searches on other sites that I looked at

 

Me too !!!
Biggest thing I learned (besides how to file square) was to keep a file for left cutters and a different file for right cutters. The tie straps do damage to the teeth of the file, keeping one for left and one for right keeps the files sharp and no more skidding across the cut face

 

I also try to use old files to rough in, then a new one to get a sharp corner to corner.

 

I use old ones to make the first stroke or two on the cutters to try to keep from chipping a new file or my old oberg files.

 

Save edge double bevel with busted up corners... /-:

 

Should I get rid of this material? Is that called a side a beak?

 

That is the gullet. Yes get rid of it

 

Thanks. What angle should I file the gullet, 90*? I think I read it is okay to use a round file in that area. I did some timed cuts the other day with the chain on the 034 super so I can see how much I gain or loose when I file it.

 

I used a 3/16" file at a greater angle than the top plate. Approximately 40 degrees.

 

I'll do that.

 

O take it back where the file won't hit it when filing the cutter. Saves wear and tear on the files and is less resistance.

 

I'll do one and post a picture and let you guys look at it so you can tell me how it looks.

 

Got a chance to use this chain in Cabool last week.



It was all that 65cc Partner wanted... But moved some pine pretty quick...

 

That chain looks pizzed off

 

It borders on useless, but it does like to eat...
Has no business on a 50cc saw, 65 is questionable...
But I just hate moving chains around, so it and the Partner just have to learn to get along...

 

how did you get a file in there to sharpen the gullet ?

 

I usually dremel material out then file once the junk is gone... That chain has been hacked on with every tool imaginable...
It's nearing the end of it's life...

 

I cleaned this gullet out. I had to file it on a 35* angle. The file would not go in there on a 40*, it will though as the chain is sharpened more. How does this look?

 

Gullet is cleaned out fine. Is the cutting edge still RSL factory grind?
