I got this 315.174921 Craftsman 1 1/2hp. router with a router table. The good deal on the table is why I bought it, but there was router with it. (I bought it from Habitat for Humanity resale shop, so don't know the owner, etc.)
The collet and collet nut are quite rusty as you can see in the photo. I also included a photo of the router which looks ok, not like it was damaged in any way. I have not turned it on yet, thinking that if there were frozen parts, it might ruin the motor. But my guess is that the motor is ok since it was in this table.
First question: Does anyone see a problem with turning this router on with the rusty collet/nut in it? Is there a problem with turning on a router if it has no collet in place? I just want to see if the motor runs ok.
I found the manual for this router on this website
. So I have a place to start.
I haven't tried anything yet, but wonder if anyone has an idea of what to do for rehab. Perhaps a website on unrusting removing the nut/collet or what steps I should take to see if I can rehab this router. I don't want to invest much money but certainly could buy collet/nut, brushes things like that thru sears.
I've removed rust from old handplanes using a couple of different rust removers, so this is not entirely foreign. (I've used citric acid and evapo-rust and immersed the parts in these with a lot of success.) I was thinking of using liquid wrench to remove this and then immersing the parts in evaporust. If that doesn't work well, I'll just buy new parts. As long as I can get the parts off.
I'm not entirely new to routers, but not very experienced, either. I'd love to be able to rehab it, since I was considering buying 1 1/2hp a router for dovetails. Any advice is welcome.
