I found somebody selling 2" CBN disks, but he didn't know the grit, and I'm guessing they are 10k+ minimum. So while they leave a mirror finish, but if basicly shaping the tool as opposed to just resharpening, I need something quite a bit coarser for the rough shaping. I do have a much coarser wheel, a valve grinder style cup, but it takes the G0704 and its 3k max spindle to turn it. I need a 200 grit cbn to turn in that high speed spindle for the rough shaping w/o putting 50 hours on that motors bearings. Unfortunately, even the Chinese are slow to catch on that putting a CBN wheel in their tool grinder is the only way to fly.
I just got back from wallies, found zip to clean this crap out of the motor, so I brought back two pleated paper fuel filters from the outboard gizmo's shelf but made for a huge 7/16" fuel tine, so I've got a jury rig of shrink tubing and 3 assorted sizes of clear plastic connecting the filter to the pump, and the other end to the 1/4" bore of the lines going to the motor. The motor connector is unplugged so nothing is running but the pump. I can throw water against the ceiling 5 feet above the tank, but going thru the motor to dribble back into the tank might be a gallon an hour, its just a dribble. Certainly not enough to protect the motor. I wonder if I plug it back in and give it the good gulf, if it would boil violently enough to dislodge some of that pink jell? 90-100 psi air blowing both ways doesn't do any good. I'm only getting maybe 10% of the flow I got when it was new about 18 months back. This is now fresh distilled water, which is a higher solvent cleaning effect than tap water. I'll let it run 2-3 days, by which time I should be able to tell by looking at the fuel filter if I need to play with the ph. A teaspoon of TSP maybe? Some lemi-shine? Sodium carbonate? But that's pretty brutal. Would need a hell of a good rinsing. IDK, you guys tell me. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
