I own an 18inch variable speed Delta Scroll Saw, Model 40-601. The saw needs two original style blade grips (although, I would prefer an aftermarket set of Delta Quickset II Blade Chucks) still I am ready to accept any chucks that will work. I was interested in the letter by one of your members who was able to find a pair of blade grips that apparently did work and would appreciate where I could obtain them. Thank you. Sincerely.
