I have seen the early scroll saws (pre 1950) had a cast solid upper arm with a spring (like a valve spring) where the blade attaches. Under the table is a oil filled casting with a crank shaft mechanism to give the vertical blade movement.
The design concept seems bullet proof and having a blade with perfect vertical movement would be normal.
Anybody know why the change over to the designs of today?
