I never intended to turn the bandsaw into a project in itself, but that's what it's turning out to be. This time, I upgraded to a link belt and added a dust collection vacuum port.
The link belt was from HF. It's cheaper than most others, but looks just like the more expensive one I bought from Woodcraft. Vibration at startup has been reduced, but I haven't tried cutting anything to see how well it's working.
The dust collection vacuum port was a little harder upgrade, as I had to take the lower door off and cut a hole. I placed the angled fitting in the center of the door, near the bottom. A test cut showed reduced dust output vs the pathetic dust "shoot" on the side.
I'll have to try some real cuts to see how well they work, but I think the dust collection upgrade will be most worthwhile.
