Playing with chain

[MustangMike]

why wouldn't a perfectly square file work well? i tried the triangle file......ruined the chain, time i got it straightened back out it was 2/3 gone.

Going with a 6 sided (or bevel) file will give you the proper angles. That is what is recommended for sharpening square.

A single bit file functions the same if not better as it contacts fewer area's when getting steep. Post a picture of your chain please

It is uneventful. I just try to maintain factory angles and factory cut speed. I use a triangle (6 sided) file cuase they were most similar to round.

this is from when i first started with square. its fuzzy

double bevel

A double bevel is 6 sided and nothing like round. Post a picture making your chain better is never wasted time.

'Square ground' (or filed) cutters have 2 flat bevels that meet at a corner, but typically not at 90 degrees, due to the compound angles.

A perfectly square file don't allow you to put a 25-30 degree top plate and a 0-5 degree side plate on a cutter..
But would allow a man to file the tops, then file the side plates seperately if he chose to do so..
Would be quite labor intensive.

Question for single bevel file guys: do you file the top plate and side plate edges separately with those files?

Just curious.

Thanks.

Single bit files work similar to a double bevel, but you can and I have before.

Using a single bevel or a double bevel does not change the amount of strokes needed. They both remove material from the top plate and side plate at the same time. The amount of material removed and from where it is removed is determined by the pressure imposed and the direction the pressure is imposed from.

The single bevel removes more material from the sideplate, creating a taller cutting edge on the side cutter, not that its used, but it is there

I prefer the single bit because it allows me to make a cleaner finish and I tend to have a thinner side plate.

I found the double bevel file to distort less .......... whereas the single bevel works very well when new, as it looses its cutting edge and more pressure is needed the corner becomes less defined due to the file distorting during the stroke

You boys better get this chain stuff figured out before September....

I need a saw first..

 

[cuttinties]

I could always use more saws haha

 

[cuttinties]

So no stop watch guys around? Any interest in seeing how big of gains I can get over stock chain with a stock saw?

 

[MustangMike]

Compared to what?

 

[cuttinties]

Compared to what?

The stock chain time vs my filed chain time.


For clarification I'm talking about timing a new loop then sharpening it and comparing the time.

I'd like to see you improve on stock Stihl RS or square. Other brands, I think it is easy.

Well if you filter back through the thread I've already improved on square chain. But RS is what I had planned to use. I have 1 loop of LGX 93 dl that I could use as well.

I need to get some time to do a few more chain tests. Been busy with garden beds and that stuff right now and a few saws that are hanging around.
