Bikerrandy, good to see you back. Great cabs, especially that Amethyst Sage. Lynn

Very cool stuff. I've never heard of it before. Where does it come from? Looks like my 14" Highland Park saw. Yours is cleaner! Lynn

Vera, Welcome from Cedar City Utah. My grandma's name was Vera, but she wasn't a Rockhound. Sounds like your husband knows what's good for him. You "inform" him & he gets you what you want. I "inform" my wife & get weird looks. Lynn

I do 1/4" - 5 cranks on my Highland Park slab saw. Some do a little thinner, especially those who sell slabs for a living. Lynn

captbob, It's sold for sealing between camper shells & truck bed lip and other uses. I'm sure I bought some from Homer. Lynn

zarguy , looks like you have a lot of grind time on your grinder . I like the bolt together idea . I looked at a friends SG today to get some ideas . He used 14 continuous blades with a formica spacer between them for a width of a touch over 1 1/2 inch . The blades are almost touching with just a slight gap between them . He says it really eats the rock . Guess I'll try to put something together and see how it goes .
Actually I have very little time on it. If it looks worn in the middle, it's because the blades vary slightly in diameter. I could probably do something about that, like change the order of the blades or dress it, but it's meant to chew agates, not nibble them. Finesse is not part of its vocabulary. I want to get it out of my arbor & on its own arbor, or mount it directly on a motor. I cut up the lids from a plastic butter tubs from the grocery store to make spacers for between blades. They're thinner than CDs & they're what I had on hand. Lynn

that kind of food you would just bring to me no sharing lol Roy, ya know, you are going to have to fight over the chili relleno casserole with zarguy. Thanks for keeping me in mind Jean. I don't know if I'll make it this year. Your chile relleno casserole is a pretty good motivation to get me thinking about going. Let's see who I can talk into driving down there. Lynn

I run mine at 1725 RPM. Most bench grinders are double that speed. Lynn

Hey Lynn, have you posted pictures of your super grinder here before? If it's anything like that cab machine you built, I'm sure it's a winner! Probably. I was poking through a Google search on the subject. I haven't looked at all the results yet. Como se dice "The Super Grinder is out there" Lynn

I'm not sure if the continuous rim blades chip any less than notched ones. I bought notched ('cause they were cheaper & I'm cheap). I only grind to about 1/16th " from the final shape & refine the shape on my 60 grit sintered wheel. I found a liquidator on ebay that had a few listings for 7" blades so I contacted them to see if I could buy a huge quantity. Many friends in my rock club wanted to make Super Grinders. We bought 90 blades for $286 shipped. That's $3.18 per. My stack of 17 blades is about 1.5" wide & cost me $54! Bummer is that I had to have a machinist friend bore them out to 1" to match my arbor. The ones I bought had a series of holes about 5/8" in from the edge. I bolted the stack together with 2 bolts. Lynn

That second cab looks like some of the jasp/agate we find in southern Utah, which looks like some of the same from the Cadys near Barstow, CA. I think similar jasp/agates are found in many places.
BTW, where can you COLLECT Pietersite? Lynn

I remember that song well. Was it 1969 or 1971? My 41 year old father was working on his Masters degree in ceramics at BYU. I heard it there in heavy rotation when I visited him there. The much younger college students played the local AM pop radio station in the ceramics lab.
My Dad also mentioned a song that had these weird lyrics "Who wants big fat girl". It was Spill the Wine by Eric Burdon & the Animals. They were singing "Spill the wine, dig that girl".
My Dad gave up on pop music after the Everly Brothers. He didn't even like the Beatles. Lynn

People spend big bucks to get a spongy pad for polishing. Save your $ and cut up old mouse pads instead. I used to get scraps of scuba suit material from a dive shop in San Jose. It was great for all kinds of uses like lapidary. Lynn

I do a lot of hand sanding on flat stock. I got tired of the paper sliding around so I flipped over my mouse pad with the rubber grip bottom and the paper stuck to it enough to keep from moving around. Makes a really nice surface to sand on, too. I have since bought a bigger gaming mouse pad on amazon for cheap. This one is dedicated to metal working. Just thought I would throw that out there. I also use mouse pads for many other purposes like wire wrapping. Flying snips of wire don't fly as far if I aim them at the pad. I pick them up at the thrift store for .25 - .50. Lynn

Go with 46/70 but be sure to use 120/200 for first Loto round. The straight 220 doesn't do enough smoothing the deeper scratches. orrum I already have a lot of 220. I was hoping to not have to buy more grit in addition to the super coarse 46/70 or 60/90. I may also use little 6lb Lortone barrels on another tumbler. Would 60/90 be better if I'm tumbling in both of the size barrels I've mentioned? Lynn

Looking forward to your tumbles Lynn. Old timer that sold rocks at shows had a bowl of tumbles set low so kids would be attracted. Said it drew the parents in and assisted sales. Good luck. My thinking exactly. I've had an ice cream bucket of local agates for kids (of any age!) in the past. Walking around an Art and Craft show can be tedious for little ones. Give them a rock and make their day Lynn

jamesp Thanks for your input. No problem about the stud. The hole is square. I'll just pick up a new one at Ace Hardware. They have 2 whole aisles of nuts, bolts, and more. Lynn

I picked up a tumbler with 2 half sized, rubber lined, hexagonal barrels at the Denver Gem show in Sept. I say half size because they are the same diameter, but half as tall as the hex barrel I had as a kid. I think that was 12 lb. Or was it 15 lb? Anyway these half sized ones hold 64 oz of water with 7/8" to spare at the top. I'm going to tumble local agates to give to kids at the Arts & craft shows where I sell my jewelry. I'm planning to buy some coarse grit in bulk from Kingsley North. I'll do only the coarse grind in the rotary & then finish up in the Lot-o. For this barrel, would the 46/70 or 60/90 be my best bet?
