Hi guys ,I've not been here for a while but I have just managed to buy myself Delta 16" Variable Speed Scroll Saw 40 - 540,it's actually on it's way to me right now. Now I know from past experience that one or two guys swear by them that's the reason I bought it . I there anything I can fit to improve it's performance like quick change blade clamps for instance . your help would be appreciated Mal (Hulkl)
