pinched bar

[Johnmn]

I picked up a new bar a while back tried to put it on yesterday and there is 2 or 3 spots the bar is pinched so the chain is tight there. What do you guys use to spread your pinched bars? Thanks

Screw driver along the groove and tap it with a hammer. Keep checking it so it doesn't open too wide.

What gauge bar is it?
Quarter=.063
Penny=.058
Dime=.050

Place a flat washer the appropriate thickness in the bar grove and tap it down the length of the bar with a hammer. May have to do this several times with a couple different flat washers of varied thickness till the rails have opened just enough.

.058 penny thanks

I have used .045 thick cutoff wheels on an angle grinder before. It takes a steady hand and very light pressure but it is a very quick fix.

The screwdriver end of your bar wrench may open it back up .

If you start the saw and use it the problem will disappear.

What kind of bar?

Total super bar

Is it the grey bar or the shiney silver bar?
Any photos?

Shiny bar

*s-word. Hopefully you can fix it. They are real nice bars.

I have a bunch of total/tsumara bars and there fantastic, sure it's not the chain?

I agree with an earlier comment to grind it rather than pry it too much, maybe a little but I'd prefer to remove a bit of metal to get the groove straight than have it not for the sake of 30 seconds

Running a couple cuts with a slightly loose chain will have it running smooth and it won't wear more material away than necessary like a grinder will.
A large flathead screwdriver is probably the best way unless you have the factory rail dressing tools. Taking material away by sanding or running it that way will make those spots thinner and wear much faster.

Run that motha

I'm going to tell you right now you aren't going to run pinched Sugi true. All you'll do is make a hot spot. The harder quality bars you have to dress them back true.

If it's new send it back.
