Hello everyone. I’m new to the forum here and am currently building a home woodshop after almost 15 years in the building industry. Thanks to all for offering such a great collaborative resource for woodworkers.
I recently purchased a Delta 37-190 from someone in my neighborhood. I probably paid too much (300) but I found that there were so few available options at this medium level of tool that this would be much better than a small bench top model. The tool is in immaculate condition and when running it works beautifully. The problem is with initial startup. When the tool is first turned on, it slowly struggles for up to ten seconds or more to power the motor. When I use an extension cord, or plug it into a 15 amp circuit rather than a 20, it actually blows the breaker and fails to start. Once the tool gets running, it runs completely fine and does not slow or stop even when removing a good amount of material. When it is turned on again right after it has been running, it seems to start up without a struggle at all. Once the machine is left alone for 30 minutes, it has the same problem again.
When I bought the tool, the former owner showed me this problem, and told me that it was solely due to the undersized and outdated electrical panel in his house. He told me that if it was run on an exclusive circuit with ample power, it would not have this issue. He also said he would take it back if I had a problem. I am running the tool on an exclusive 110v 20 amp circuit, and am still having the problem. It seems to me that this should not be happening with this tool, and that it could be a problem with the “centrifugal switch” as I have noticed mentioned in other topics here. I verified that it is wired for 110 and not 220.
Does it sound possible that this problem is really due to a lack of initial power available to the machine, or is it likely that the machine needs more power because of a problem with the motor? If so, how difficult is it to open the motor and attempt to restore the centrifugal switch? I have tried cleaning and oiling what I can without taking the motor apart. My big fear is that in a few months, it will not start at all and I will be stuck paying to replace the motor. If this is really simply due to a lack of power and no fault of the motor, I am fine with that. If I need to restore, repair, or replace something, I am tempted to bring it back to him rather than deal with the hassle. He seemed like a genuine guy so I’m hoping he will honor his word. I would likely buy a Ridgid JP-0610. I appreciate any comments and expertise anyone has to offer.
