This is going to take something more like a regular trim router if I can mount it correctly.
I knocked that elderly B&D apart tonight, far enough to see that it only needs the bearing on the chuck end of the shaft, but the collet is really a trashy collet, so if I follow that idea, I may as well start by making my own shaft to take a decent MT2 collet as I have those. Which may be quicker to call Chris at LMS and just have him send me the whole assembly from a micromill. I wonder how fast one can spin those bearings? Pricing that out comes pretty precious though. :( And its top driven, not what I had in mind at all. Maybe the B&D armature is the cheapest way to get .005" accuracy, in which case I have a newer one that may be better, I had a heck of a time tonight getting the front bearing retainer nut off the older one, the chuck wrench had burred up the threads some, and that steel is surprisingly hard. Or just go get a trim router & make the mount for it. Quicker, thats for sure, but I didn't want to carry that much extra weight. HF also has a die grinder that might work too. I'll go look again. I have not identified the bearing yet, still stuck in the plastic end cap & my snap ring pliers I still need to find. The darned thing is rusty! And I have a sneaking suspicion the bearing back on the brush end of it is a torrington needle cageless as the front bearing obviously does all the end play control. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
