@ jmbfestool, Is that motor something you can keep on the shelf and easily replace the motor in your Kapex when it breaks down?
In my biz experiences, when I have a piece of machinery that I really need every day, or nearly every day, I keep a spare. If i need a mower every day, I have two. If I need two mowers every day, I keep three. And so on. When I was in construction, I operated the same way. If I needed one tractor/loader, I kept two. If I needed one ladder, I always had three. I always did more with less labor than most of my competition and did not lose days because of breakdowns.
I am sure the answer to my original question is that the motor cannot be easily replaced. If that is so, but you are more profitable with using a Kapex than you are with any other SCMS, then go with the Kapex and look for a less expensive back up saw to keep you going should the Kapex fail. If it is not fixable to your satisfaction, then look for the next best replacement and still keep a less expensive SCMS on hand. That might even work to your advantage for the times when you need to do two different set ups for one project or operation on several pieces.
Even tho I am a oneman operation and sort of phasing myself out of biz (it'll be awhile yet, I am only 39 you know), I still keep two mowers operational. Two weed whackers. Two hand blowers (backpackers kill my back) Three heavy wheeled blowers. Two extender hedge trimmers. And etc-etc-etc........... I just accept the fact that machinery will break down. I can make more money with a lot less hastle when my method for repair is to keep working at what i do well and let somebody else do my machinery repairs who do that work a lot better and more efficiently than I ever can. If they can't do my repairs, it is still cheaper for me to find somebody else to make the repairs. Because I have spares of nearly everything, I just keep going, and going, and going. Maybe when i get to be 40, I will get rid of the spares.
