Chopmaster Blade Tear-out

[Hans Braul]

I don't know if I can adjust the alignment - will have to check tomorrow, but I don't think so. Also I could have a runout issue. I'll need a dial indicator to check that.

I'd expect a better cut. Somethings wrong with the saw or the blade or both....have any other blades to compare it to?

[Hans Braul]

The blade that came with the saw (which I assumed would be next to useless) gives comparable results. I'm thinking it's got to be the alignment or runout. I will continue to troubleshoot.

Thanks!

Check the run-out ... since you've had the problem from the start, the problem is most likely with the flange that the blade is tightened.
A dial indicator would help, but, not completely necessary to see the run-out.
Put a (perpendicular to the blade) pencil to the blade ... just touching the blade ... and carefully rotate the blade 360*.
When you come-around full-circle ... if there's run-out ... there will be a gap between the pencil and the blade.
'Lock' the pencil in-place with some tape ... use a feeler gauge to measure the gap.
Lacking a feeler gauge ... use pieces of newspaper = about .002 per piece.

Very good advice! I'll do this tomorrow. Thanks for the help.

I'll report when I get to the bottom of this.

Yep, you're on track now. If two blades give similar problems (even understanding the difference in quality of the blades) I would lean toward the saw. A quick alignment check should tell the tale.
