I sneaked out of work a bit early today. I mean it was in the 60's today, how can you be expected to stay in the office all day :-)
I have now cut my first three tubes. I know this is a small thing but it is a start.
Lesson learned today. When using an abrasive disk in a miter saw the blade flexes side to side very easily. You can end up with cuts that are not very straight. I think the trick is to not force the blade.
