Why won't it cut?

[ihatesaws]

Hi all,

I decided to resurrect a 024 saw which I left in pieces for ten years.  I found two rusty chains.  I sharpened both and filed down the rakers.  The first three images show the bad chain which barely cuts and the last two the good chain which cuts great.  I know they are not the same design of chain but there must be more to it than that????

Thanks

Its quite hard to say without a closeup side profile picture, but I'd say the first chain (top three photos) has taken a really big hit to a stone or something similar and has a few bluntened off points.  All the teeth need to go back. Get a new file, it helps remove metal faster. A good scrub with petrol wouldn't go amiss either.

Good username.

 

You haven't sharpened it enough. For example, you need to take about a quarter of the tooth in top picture off.

Teeth look a bit hammered as said above. Also that file may or may not be doing the job. Get a new file for about £1.50 and then give those teeth a really good going over. 👍

 

Hope the resurrection goes well. Sounds like a fun project.

All pictures show damage to the cutters not just the top 3 . There is top plate damage and side plate damage . You have not sharpened the damage away .

The bit that’s coloured red above is damaged…. It will never cut nicely like this.

 

 

You need to file the tooth away upto the blue line (above), in order to remove the damage.  The file* also needs to be re-angled in line with the witness mark (the green line).

 

*Not that file though… Don’t bother with doing anything until you have invested in a new file.

That has got to be the best layman sharpening guide ive seen. 👍
 

Don’t forget to reset the depth gauges/rakers after sharpening.

That's great info.  That file is new.  It never did any work.  It just sat there for years rusting.   I just need to file the rust off 😏.  If I get the saw running well I'll invest in a new file.  It will be some meditation exercise if I have to take that much off all the teeth.

That kind of damage is where you start working out the value of your time vs the value of the chain that will be left once you've finished.

 

I would suggest to get semi chisel chain to replace it, easier to bring back to cutting condition after you hit something hard.
