holajonathan - I have no doubt you'll cut that rough, and I felt bad when you guys posted pictures of all that white substance all over the ground!
It's been a while since the boxes were put together, but I thought there were at least a couple in each box small enough to cab without sawing. God knows I dug anything large enough to cut outta' the mud that day. Threw as much back - after spraying it off and looking at it - as I put in the buckets.
I had the same idea -- cabbing a few small pieces without cutting. Since a cab needs a flat back, and no pieces have perfectly flat sides, I took a few to my flat lap to give them a flat back. I either need a new 80 grit lap disc (probably) or this is some really hard stuff (or both). I spent too long holding them against the flat lap. Pressing hard, then lightly. Spinning them in circles. More water, then less water. Trying the outside (faster spinning) edge of the disc, and then the inside edge where I can press hard. Spinning, waiting, holding in place... watching TV... thinking about the snow... feeling hungry... getting bored... thinking about cats... And they never got flat on the back. I felt like I was grinding on a Montana agate. |

It came down heavy and wet for half a day with temps hovering around 33 degrees, and then the temperature plummeted. I've learned from 30 years of shoveling snow that if I don't get the slushy stuff up in a hurry, it turns into ice, and is impossible to remove. It was an annoying snow storm where it snowed at a slow to moderate pace for about 48 hours straight. How much total did you get? My sister had about a foot of it (Chicago 'burbs). Probably about that. It's hard to say since it was windy. There are 2-foot deep drifts, and other areas with 2 inches. Not the snowmaggedon predicted by the "Winter Storm Warning" (15-18"), but a substantial snowfall nonetheless. |

Yeah, about the same. Here's pic she sent me:  |

Yeah, about the same. Here's pic she sent me: Only difference is she doesn't have over 900 feet of driveway.  But I've got a tractor for that. I complain about the 30 feet or so of walkway that I have to shovel by hand. I used to shovel three or four times that when I lived in the city, just to keep the sidewalk open for the kids walking to the bus. Darn corner lots. |

Good looking material. Perfectly done cabs Thank you my friend!  Cabs are definitely easier to make look good when the material is great material! |

Cabs are definitely easier to make look good when the material is great material! meh… I’m pretty sure you could polish a turd and make it look good at this point. May be a turd at the end of the day, but you’re skilled enough to make it shine like a diamond. |

Thanks for the compliment. |

jasoninsdWas this material hard to cab? Hard as in mohs, not hard like long division.

jasoninsd Was this material hard to cab? Hard as in mohs, not hard like long division. That made me laugh. No. I really didn't feel it was overly hard. That's why I was surprised you had said you were having a heck of a time on your flat lap. I was removing material on my 220 if I added a little pressure when grinding. |

That's why I was surprised you had said you were having a heck of a time on your flat lap. I was removing material on my 220 if I added a little pressure when grinding. They were ambitiously size pieces that I was trying to grind flat. I think I need to set up a real drain and continuous water supply for my flat lap. I use the little water container that came with it, which might hold 12 ounces or so. Because I don't want to refill it ever 2 minutes, I set the flow pretty low, just enough to prevent dust. I don't think that flow of water is washing away the slurry fast enough. When you cabbed on your slant cabber, did you have a continuous supply of water, or were you constantly refilling a little container? And don't tell me long division isn't hard. Very nearly kept me in the 4th grade for a third year! |

Very nearly kept me in the 4th grade for a third year! My slant cabber had a reservoir that didn't hold a ton of water. I kept a gallon sized pitcher next to it and was constantly refilling the reservoir. At first I was using too much water. Then I went the opposite extreme and was using too little, and ran into the problem of not washing away the ground off material. After awhile, I got a little more comfortable "reading" the grind and the amount of water... I never said long division wasn't hard...but your reference was extremely funny! LOL |

Hmmmm - holajonathan - Were you trying to flatten those St Johns on your flat lap? After your very informative post on sintered wheels, I assumed you were grinding those pieces on a wheeled machine.
Flat surfaces are possible on wheels, once the muscle memory is there. I'm trying to figure out how I would explain it, if anyone here hasn't done it this way.
Easiest way (might make no sense at all) I can describe it - is to grind it any way you want until it's more or less flat. Then hold the cab firmly in the same orientation relative to the wheel as the cab back is moved in a circle over the same spot on the face of the wheel.
The angle of the cab relative to the wheel does not change. It's easiest when holding the cab with both hands to keep it in exactly the same orientation as it is moved around and around against the wheel. A dop stick can be left on to help hold it, but keeping even pressure on both "end" of the cab is necessary to make it work.
If anyone who's never done this understands ANY part of what I just said, then today is a very good day.
This method will definitely flatten a surface enough to move on to polishing on a flat lap or whatever.

It totally makes sense. It's the same concept used when doing a flatter dome...you just have to pay attention to the stone's orientation to the wheel... |
