Having a problem with my Porter Cable 7518 router that I hope some veteran woodworker can help me with. I am doing some panel raising with a CMT bit. On the first cut with the larger bearing the bit and router get stopped. I pull the piece away and the router is still on but not turning. If I turn it off and back on then the it starts turning again until it jams again. Any help would be much appreciated.
Thanks

Not uncommon with the 7518 microprocessors to do just that. Some folks have said an air blast will do it. For me it was the new Milwaukee. I ran out of patience. Use that tool as designed (x the handles) and it will never wear out.

Thanks for the reply. I will try the air for now. Is the dust getting down inside do you think?

One other thing... What Milwaukee model?Golfisher
5625, installation sample at the selection link.
How deep a cut are you taking and what speed do you have the router set at? Low speed, deep cut, high feed rate will stall it out. Shallow cut, high speed, slow feed and no problem. The router will overrule you if you make a bad choice in cutting. Hopefully, you are using a router table with a fence and taking incremental cuts and not cutting to the full depth by hand.

CMT raised panel bit using the 2 bearings supplied so 2 cuts at 10,000 rpm on a good table and fence. When is stalls it stops turning even when I pull the piece away. Then need to turn on and off to get it spinning again.Golfisher
10,000 is the lowest speed on the PC router. I know all about what the experts recommend for large bits but it doesn't work in real life. There hasn't been a shop I've worked in that uses variable speed shapers, tenoners, foursiders and so on. They turn some big cutters. An 8" table saw would run faster than a 14" if tip speed was a real factor. I've never had better results running slower. The router is telling you it's overloaded and shutting down. I'd turn up the speed first, slow the feed rate, take less of a cut than the bearing allows, check to see if you have enough electricity to the router. Running lights, a vacumn and other tools on the same line can eat up the available juice. If none of that works, take the router in for a service test. Once you get out of the low speed range, I think you will be fine.Beat it to fit / Paint it to match
