Nothing, I have maintained it forever, just completed 30 nameplates for an office. But, new Excalibur-type saws are a bit easier to operate (blade threading, tensioning, etc.), as my saw is 30 years old. Plus, the additional 2 to 3 inches of throat is enticing.
I searched for threads and reviews that might provide useful info to decide between the Delta 40-694 and Pegas scroll saws and so far, nothing. Can anyone provide some comparison or pro/con info to help me decide. The price difference is substantial, but they appear to super similar. I currently own two scroll saws (hegner and delta) that are both 30+ years old.
Thanks
