fin-bore III blade angles?

[ecmilley]

my 8 inch fin bore isn't cuttiing very good so i bought some new blades and it isn't any better, been told to shim it to get it to cut properly again, anyone know what angles to shoot for or is it a matter of trail and error?

this would be reason #1 not to lend out an auger banging it on the ice to clear it is a no no

I found that when I replaced the blades, the auger goes back to normal, so I'm no help here.

 

If I was to lend my auger again, I'm gonna get the guy to drill me a hole right next to me so I know they know how to use it before I lend it to them. Sucks when your auger is destroyed before the end of the day and you can't move anymore.

Definitely sounds like something is bent out of angle as you shouldn't have to shim the blades at all.

 

Perhaps you can compare your auger to a good one and see where it might be bent and try adjusting it from there.

If anyone figures out what angle they should be at, I would like to know also. I tried shimming, no luck.

Like Jet said, sounds like something is bent. The new blades should cut like new, with no maintenance required.
