I have acquired a 2nd hand router, did some cosmetic cleaning and gave it a go. Runs at speed fine but every few seconds, (3 to 6), there is a clunking noise.
I did not notice the clunk when It ran up right with a load, but I only ran it about 10 seconds that way. I made a table with router upside down and started hearing the noise. Seems to frequent under load. Other wise it does its job well. CLUNK clunk ... CLUNKclunk. Any comments will be appreciated folks.
