True up a wacked chain?

Esteemed forum of FHCers,

I have been the lucky recipient of some old chains. Plenty of meat left but the right cutters are much larger than the left. This is true on 3/3 chains.

No problem I thought, threw them on the HF grinder (only use for rocked chains) and brought them down to same length or close enough for a hack.

Here's the rub... Left cutter in pic is 0.279" long and 0.150" wide; right cutter is 0.286" and 0.162".

That width is hugely off, quite visibly so. I don't think the added 7mils accounts for that width delta.... or does it?

Is there a way to true this up? Will this be a problem? I don't want to waste time hand filing if I will just be cutting circles.

And possibly another thread, is there a way to true up worn guide bars on the inside groove??

 

As long as the angles are the same on both sides, I would run it. No need for analysis paralysis.

 

As long as those numbers are accurate I would run it. I measure my new chains and found a name brand off by .025 NIB one time. Most are in the .005-.010 range.

This isn't a precision cutting machine. Hell, the driver to bar slop is probably .020 easy.

If it cuts and curves one direction, take a little more meat off the cutters on the outside of the curve.

 

I use a crescent wrench to measure if there the same . Thats not too precise bit close enough.

And use they do make a tool to close the vids bar groove back up. I am at the end of my wifi range and dont feel like dealing with the wait or else I would link you too it. I am sure someone would come along with it though.

Test Run it to see of it cuts bad. Worst thing is you have to resharpen???

 

Like Clemsonfor said, a link to a bar tool is easy. Took me 30 seconds with Google

Yep...know that tool. The Chicago Electric grinder

 

Old man thats not the tool I am talking about. That thing flattens the rails and takes the burr off. The thing I am talking about has rollers to roll along. Let me google it.



This is the tool I am talking about (see link below this paragraph). It closes the rails the one old man posted squares up the rails and flattens them. You need both to work on a worn bar. You can use a flat file to dont he same thing as oldmans link.

Run it .

 

OK fellas, I'll keep on grinding and get it sharp.

The bar rail closer may work, the pferd link isn't going to help as the area of concern is the "V" shape and lopsided groove. I have 3 20" bars now, so this one may just be a backup.

 

Close the groove down is the only way to fix it besides grinding the groove open to .058" or .063".

 

I'd just run that chain. Cutter don't 'really' need to be same size/length as long as both sides are sharp.
