Mr Rapid Roger I did use the hot water trick and a drop or two of air tool oil the when it was heated up i used the pliers and screwdriver trick to pop it on there piece of cake when you know the tricks thank you. Now as far as the 40-694 saw is concerned. Damn I had to learn all over again how to use a scroll saw. That cheap $100 dollar saw compared to the delta is beyond night and day. Just to prove it to myself I took the two blades that came with the new saw and put one in the old saw and the other in the new saw, with a piece of 3/4 oak in hand I test cut on both saws. Seriously amazing the difference, I found I have been missing a lot in quality.
