bar modification

[chainsman1]

can i use a 9 pin rim on a stock bar or i have to modify it?

that will be my first try with something bigger than a 8 tooth

its a 3/8 with a 16 inch bar...

9 pin mostly requires taking just a little off the heal. depending on the saw and brand of bar you may need to move the adjuster hole and extend the bar slot. If you are dealing with an outboard clutch then likely need to trim and extend the bar slot more just to get the chain on.

Go to a 10 pin or more and then you really need to look at cutting a bar down from a longer one to get enough depth at the heal.

thanks timberwolf,i will try it when my saw will be done

I've found that the steel is extremely hard, real tuff to cut. I've found that grinding works better. I use my 1/4 inch air grinder with cutoff wheels, stones, grinding cylinders.

I added drive links to my "race" chains to get more adjustment, and I gorund a little off the heel of my bar.

not to fit a 10t rim you didn't. the tail of the bar needs to be shortened to get the width of the bar back so the chain can stay on.

I have one bar that is cut to run 9/10 tooth sprockets, on this size you don't have to remove a whole lot.

9 or 10, you're still removing quite a bit to get the width of the bar to match the dia. of the sprocket. way more than just grinding and adding a couple of links.

If I get a chance I'll take a couple pictures of my bars to show how much you have to grind away.

I didn't take off too much and I haven't lost a chain yet.
