Thread: When is old too old? 2004 Shopbot PRT

  1. #16
    Most of my experience is with production-level routers. What I see is that while the frame and components can still be sturdy, the MRO costs become more frequent and more expensive: Spindle replacement, limiter stops, etc. Also, the software just becomes obsolete. I view routers like edgebanders: You should plan no more than a 10-year life cycle and perhaps 2/3rds that if you run it hard. Though many folks limp their machines on for longer. Just my observations.

    That's like comparing a USA made model T to a Nissan Acura. And by the way, my Seiko is made in Japan - world of difference from China stuff.

    That "vintage" Singer was a POC. That's why I got rid of it. Go USA!!


  6. I love my cast steel 100yr old singer
    It will outlast anything made today...its a workhorse.

    Walter, I rebuilt an old ShopBot PRT for our local high school a few years ago. I ordered a new control box, it was a snap to install and the upgrade was nice.

    If you wish to continue using the ShopBot Control Software, then your options are finding a used controller or purchase a new unit from ShopBot.

    If you are open to other controllers there are a number of options out there that you can purchase complete or build yourself. I design a number of SB replacement controllers based on the Centroid Acorn Controller that are built, sold and supported by very knowledgeable former SB users. We're pretty proud of them and they have features above and beyond what has ever been offered for the PRT. Look over the attached comparison chart.
