Probably wouldn't do to attempt storing nasty videos being uneducated on the privacy settings. Scary thought making such a boo boo. Made a few of those rock grinders, must say this one is the fav. I keep about 15 rocks next to it. Hit on them here and there, Try to avoid burning out on any one rock. Man I wish I had that thing in the field on the Rio Grande to window rocks with. It is difficult to see the innards on those bleached cobbles. And the better cobbles down on the lake have thick alkaline coating(closer to the river the higher percentage of agates). Make sling shot balls to fend off the smugglers.

By "gone sideways" I was picturing something catastrophic, but that project's coming along nicely. Man that digests an agate quick, and surprisingly no chipping. Makes my fingers nervous but that's probably a healthy reaction.

Cutting rate for moss agate about X2 that hard pet wood. Cutting rate for Georgia granite about X4 the pet wood. Cutting rate for coral about X.8 the pet wood. Cutting rate for Mary Ellen jasper about X.3 to .6 the pet wood. That stuff is hard and dense. Way slow to grind. Awesome stone. Cutting rate for most Rio jaspers about 2-3X the pet wood. Cutting rate for crazy lace about X2 the pet wood. Glass and obsidian very fast. Of the 5 big (Mohs 7) rocks put in the 5 tumblers this pet wood was slowest to grind. 3 mosses, the pet wood and a Rio jasper This pet wood was slowest to have the grind marks tumbled off by SiC 30(slowest to grind). Roy traded me this agate. Can't remember the name, Sumatra something Flame ? It temporarily dulled every diamond wheel it ever touched when running dry. Hardest rock ever attempted. The saw did it though, thanks to slow feed and oil. Only ground the sharp edges. It polished by looking at it. Fine stone.

Mary Ellen was very slow to grind. A test for the diamond wheel longevity, such tough rocks will wear out many brands of diamond wheels in a hurry. toiv0, fine stone. Maybe the finest I have ever owned. Beautiful. It is a function of the hardness of the sintering and quality of the diamonds guessing. The diamond wheel passed in flying colors, but my patience started wearing out. Will do it in shifts. Cherts, corals, Mary Ellen and other rocks silicified by dissolution of silica rich water are the hardest toughest stones for the most part. Mary Ellen, betcha it will tumble like a Montana. Will be given to toiv0 when finished for payback: www.flickr.com/photos/67205364@N06/35413414961/in/dateposted-public/

No, only lots of single saw blades. I prefer the faster cutting and larger diamonds of tuck point blades and cups. Most tile blades have smaller diamonds to prevent chipping the glaze on tiles. Cut smoother but remove less mass. I can't tell if there are notches above 800 RPM, the notches run smooth after that speed. The tuck blade in this thread is running 3600 RPM and the notches are totally negligible. However they do help bring needed water to the stone at the cut. The water has to be cranked up fairly fast to keep up with the cut rate of the coarse diamonds at 3600 RPM. The water totally smothers the loose dust coming off the rock but does not wet the rock directly at the cut instantaneously. A short but disappearing dry spot is apparent at high feed rates viewed at the cut looking from the blade shaft.

That looks as cool as playing in the sprinklers on a hot summer day. Of course, you'll want to play in the sprinklers after to wash off the rock snot. Lynn

I have a garden hose turned on with a fine spurt hitting the blade just as it exits the slot in the table table from the back side. Aimed tangentially to the blade edge and to right looking at blade. Apparently the spaces sling the water to the right because of the spaces between the segments for a darn 'dry for operator' operation.

So far so good. No imbalance issues. Big factor in any diamond cutter.
Causes
1) shaft is not perfectly aligned or straight from the start. 2) diamond cutter is not balanced or is slightly out-of-round 3) simply uneven wear due to many reasons such as a softer sintering or high sintering 4) excess rotational weight at high speed for bearing arrangement
Others, but once the rock starts bouncing against the wheel for any reason the wheel can become garbage as it creates an increasing out of balance and/or out of round situation. Short shafted direct mounted blade to the tile saw motor is a well aligned rigid high speed arrangement. Going to be hard to beat for the money. Plus excellent ground fault protection and water proof bearings.

Next project. Hockey pucks of various sizes. Most river cobbles lend themselves to discoidal shapes.
This arrangement should whip out discs in a short.
