I thought i posted back. The bar cut me while trying to dress it. It had burrs all over. Wear from a loose chain i guess.You never commented on how much wear you found on the bar, particularly if there is any side-to-side flop with the chain. If you had significant burs on the edges, it is quite likely that your bar groves are worn or spread too. That can be fixed too, but it is somewhat more complicated than just dressing the rails. Regular bar dressing will prevent this problem by lowering the edges a little each time, and that removes the most worn inner part too, but if you have a lot of flop now, you have to grind a lot off to get back down to straight groove walls. If the inside of the groove is notched on either side instead of just spread in a V shape, you do not have any choice - you MUST grind off enough of the rails to get down to the bottom of the notch.
There is a special tool that uses rollers to squeeze the rails back together, but I do not have that. I have learned how to repair that type of wear with a hammer and vice - it is not hard, but it does take a while, and you have to have some finesse; if you just start wailing on the bar with a hammer you will ruin it real fast!. I have also heard of some folks putting on a thicker gauge chain to use with a worn bar instead of trying to repair the groove shape.
I would say its pretty sloppy so the chain is walking. I didnt think to check side to side but im sure its going to be bad.
This makes me wonder if this is why i get wavy cuts on my chainsaw mill now.
