Hello members, looking at getting my first scroll saw tonight and wanted to know what key factors I should be checking to ensure a machine is good to go. I’ve been making furniture for about 8 years and have experience with all the usual woodworking machines and their setups but know nothing about scroll saws. The machine is an Excalibur of unknown model number currently, with an approximate cost of $100 (part of a package deal)The back of the saw resembles a backwards #7 (see image below)and the machine is purple. What do I need to check to make sure it’s in good running condition? Thank you for any help you can provide.
