Size

[woodturner]

I'm considering getting the chainsharp by Pferd. It offers filing guides 7/32", 3/16", & 5/32". It will be for the Husky 350 saw.
How is it determined what size I need for my chain?

Thanks,

You need to know the pitch of your chain,1/4 and 3/8lp = 5/32, .325= 3/16, 3/8=7/32. usually.

The pitch of the chain is stamped somewhere on the bar. What should he look for?
It's probably a .325, look for a little .325 to confirm that, right?

sedan posted what is normally the best rule of thumb. if u are really interested in possibly experimenting for better results. use the 3/8 on an old 325 chain and play some with different angles an such. ive done that with surprising results.. but its just a hunt for something that mite in cerrtain situations make for an good cutting chain. goodluck.

I think Tony meant to say 3/16 not 3/8. Some .325 chains also use a 5/32 file instead of 3/16

Ive always used the 5/32 files on 3/8 LP chains, for the regular 3/8 chain I use a 7/32file, for 1/4" .325 and 3/8LP the 5/32 is appropriate, the 7/32 is fine for 3/8 and I think .404, and a 5/16 for 3/4" pitch.I'm pretty sure that this information is right but if I'm wrong feel free to correct me here.

I meant to add this when I initially posted this, & I've been sick & still feeling poorly, so I haven't been back to site.

The Pferd chainsharp works on full comp chain only it says in catalog. What is full comp chain, & how do you know full comp from another chain?

Thanks,

Full comp has a cutter, tie strap, cutter, repeat
Skip tooth has a cutter, tie strap, tie strap, cutter, repeat

Full comp is for shorter bars while skip tooth is better for longer bars because it has less teeth to sharpen, doesnt take as much power (half the cutters) but it can cut somewhat slower (half the cutters).

You left out semi-skip.

wood turner;

Full comp chain has a cutter immediately before and after each drive link. Skip and Semi skip have cutters spaced farther apart on the chain. This would screw up that sharpening guide because part of it must ride on the top of the preceeding tooth while the raker file engages the raker and the round file sharpens a cutter tooth. It requires proper tooth placement to work right. Full comp is by far the most common cutter sequence. Hope this helps.
