This is not a slap against anyone because I am a guilty as everyone else but we scrollers try to get blood out of a stone. I worked in manufacturing. Machine hours / cycles were tracked and maintenance was done on a regular basis. Sometimes is was simple and sometimes it was a complete overhaul. Beyond that we knew that every machine had a life expectancy. If you are going to run a business and do production work tool replacement and overhauls have to be figured in as the norm. Most scroll saws are not designed for true production work. They are hobby tools. Hegner probably is the closest to a production machine but even they need to be maintained. Hegners cost about $1,800 new. Most of us, l include myself, are not willing to lay out that kind of money.
Devin, I wish you all the best in your search. If you are running a business I would suggest have more than one saw. Murphy 's Law is alive and well.
