Porter Cable PCB375SS

i just got a porter cable 18 inch scrollsaw and seem too have two issues. first i use spiral blades, unpinned and i cant seem to get the blade tightened without it twisting and breaking.second thing is the blade doesnt lift enough to feed the blade thru th holes.i normally don,t go thicker than 3/4 inch wood and the arm doesnt lift high enough to insert the blade from underneath.am i missing something or should i go back to using my old delta.

When my DW 788 started to act very erratic; I looked at having it repaired and had sticker shock. It had to be thumped to get it to start sometimes and the speed would very noticeably surge up or down while cutting with out any reason.

SO I bought one of these P-C ,s I thought that I would just use it and get the DW redone. Well I like it better than I actually liked the DW-.

Speed remains more constant, MUCH better light situation, and a dust collector too.  I have not used it quite as hard as I did the DW, but have cut 2 by (4-6) things many times and it has had excellent power too. To me the blade change is easier than it was on the DW also. 

The DW has the advantage of a 2 inch larger throat, that was the only thing better so far that I have found.

I am actually looking at buying another like it to take in the 5th wheel trailer when we go.
