Default Pc 7518

Would like to know if PC 7518's (purchased in last 2 years) are still performing well.
Particularly interested in bearings, and the 5 speed changer.
And if the new casting (shock-free?!) is electrically safe as they say it is.

1st failure in the 1st month.. none lasted linger than 2½ months
one speed controller down and 4 bearing failures 3 of them catastrophic... Fields and armatures damaged..
purchased 2 years 5 months ago...
installed 40K ceramic bearings in the two remaining routers and bypassed controllers... their bearings became quite noisy..

FWIW... there was a recall on them...
no shocks ever felt...
these 6 routers (motors only) were purchased, installed in crude tables w/ JessEm lifts and put into extended hard production for a single large, as in really big, Tudor/trim project...

I have also had bearing problems with my PC sanders Pat. When I replaced the bearings I found out they are some of the cheapest ones you can buy. I am guessing that probably holds true for their routers also.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

That is sad to hear. My PC 7518 is older ( 10 years or so ) and it is a work horse. I am sad that the quality has gone down so much.

1¾'' rail and stile...
2'' thumbnail..
glass door bead... 1½''(?)...
assorted ogee.. edge and groove... 1''±...
*picture molding....
*chair rail...
*base...
*casing..
*crown...
*built up...
*hand rail..
*these sizes were all over the map...
mid 5 figures in LF all totaled...

never kept track of actual machine in operation hours..
some days.. all day...
other days an hour or two...
or not at all...
there were six fixed set ups w/ power feeders and two operators..
used up around 90 bits total for the project...

the idea was to use the PC commercial motors for the heavy work in the tables and 1617's and 19's for hand held..
finished the job w/ 1617 motors in the tables...
job lasted 7 months...
15 routers...
replaced the 6PC's w/ Bosch..
1 Bosch stopped working due to brushes...
1 pulled from service due to noisy bearing(s)...
when PC CS found out their motors were used commercially they wouldn't warranty them...
did notice the bearings in the PC's leaked but not till after they were torn down.....
according to my bearing wholesale the PC bearings are only good for around 16~18K RPM sustained no load...

and correction...
it was 30K RPM sustain ceramics I put in the remaining 7518's... not 40K...
also there were two speed controller failures.. not one... the caps on the board split/separated...

Pat... you having 518 issues??? considering buying one???

This would have been the week that I'd have finished chewing thru the restraints...
If only new layers hadn't been added....

I think you ruined Pat's day, Stick. Those runout figures you posted are somewhat outside of Pat's normal expectations!
