Ok, not technically a lowrider build (but IS how I ended up with the 611) but I figured maybe more help here than elsewhere.
The 611 has developed what i consider a problem. After running for even a short time, even free spinning, the collet nut becomes noticeably warm. Running for a few minutes, it becomes uncomfortably hot. Like, i-have-to-be-careful-changing-tools-hot.
At first, i thought it was just poor feeds/speeds getting me into rubbing, heating the tool and then the nut. My OTHER 611 did the same thing and then the speed controller gave up. I have no idea if the two things are related, but that one is still under warranty so I’m sending it in for evaluation. They said they’ll check to see if i misused it, but they don’t offer any suggestions on how they define ‘misuse’ so i can’t save them any work there. That one has never experienced excessive run times or anything other than wood, generally with 1/8 bits, occasionally 1/4…smaller than i would use by hand. Max cost is a full rebuild (assuming they wont warranty it), or about US$95…which I’ll pay if their definition of misuse isn’t favorable.
The only thing that comes to mind is maybe the bearings are giving up, creating extra resistance/friction that translates into more heat? If so, maybe the speed controller tried to push more current than it could handle? If so, maybe I’m about to cook the other one? That’s what concerns me right now, so I’ve taken it out of service (time to get back on that 660 speed controller, i guess) until i can get some ideas.
Anyway, if anyone has seen this and solved it, I’d like to know because I’m sure it’s less than a full rebuild to address now. And since I’m resizing primo, maybe its a good time to get a proper spindle for not-too-much-more than a full rebuild every once in a while. I DO have other uses for these routers.
