Re: [CAD_CAM_EDM_DRO] Re: Router life, getting better bearings,

Hi Ballendo;

Krytox is a very intersting material and certianly has its uses but I do
wonder if it is worth the expense and trouble.

At this point I will have to take your word concerning the better
classes of bearings. I do have to wonder how much longer they would
run at high speed to justify the cost. It becomes hard to justify
investing money into a router equal to half its cost much less the its
full cost. One must not forget that routers also wear else where,
such as the armature, so your investing heavely in bearings for a unit
that is already degrading.

Thanks
Dave
