I'd appreciate hearing your experience on this.
We've been discussing the vagaries of saw top guards on the other thread, and the Ryan made the point that (presuming correct blade alignment so that it's not cutting on the back stroke) much of the dust the top guard has to deal with may be the result of the below table dust collection arrangements failing to 'empty' the blade. i.e. dust created on the downward cutting stroke being carried around and up the back in the tooth gullets and thrown into the air.
What's your experience? Are there lower dust chute arrangements fitted to some models of saw that do a good enough job that for example it's possible to work when required with the top guard removed without finding the air filled with dust - or worst still having dust thrown forward into you face?
Dust system performance is surely a factor in this, in that decent air flow should make the job easier. What's the experience in this regard?
Have you formed any views as to what the critical success factors are?
Thanks
