The poll needs more options. I don't use my SS's as a table saw that often but if I do I always use the lower guard but almost never use the upper.
I dislike the implied assumption that guards = safe and no guard = unsafe... I do not believe that conclusion is a given. I believe from from reading many previous similar discussions that many here slap on a guard and then shift their mind set into complacent mode because they then "feel" safe. I believe that "mind set" and a full fundamental understanding of the dynamics of the operation = safe... along with having the sense at times to ask "why am I using a dangerous power tool to make this one tiny cut on such a small piece?"
I think this is as far as I care to go down this road "again".
Just FYI, I did not vote.
I did not equip with Shopsmiths in spite of the setups but because of them.
