Three weeks ago I bought a RYOBI 16" scroll saw. I had so much trouble trying to get the blade to stay
in I returned it the next day. I now have a DELTA
SS350 Shopmaster. So far the blade changing and
holding does not seem to be a problem.
On another website someone mentioned a removeable
lower blade holder that fit into a cage which
allowed inserting a new blade in the lower blade
holder in the next room if you wanted to, and just
slip it through the table opening and lock it in
place. Not sure about the brand name, I think it
was a DEWALT.
