Most auto makers use silicon gasket instead of gaskets. Don't use regular silicon caulking. Working around restaurants for many years it never held up around grease. Any auto parts store would have a variety of colors to choose from. I'm sure grease would be fine too. It would be best if it is sealed up either way. Around here anything with oil or grease is a dust/dirt/sand magnet. thx for that tip John. Yes I used the black stuff specifically made for gasket making. Not expensive.

Tom, I had the same quandry. I simply put a bead of silicone caulk around the mating edge of the oil cup then attached it to the face of the saw tank. Don't overtighten. Let it dry for a day or 2 and you are all set. Pretty easy to make such nonload gaskets with silicone caulk. It has held the oil perfect for many years. HTH - Mark

I have not seen this material from Panama. Not surprising, because about the only Panamanian material fairly well know is the agate found in the dredge pilings from the original Canal. Santiago province has lot of different geology, but yours is really unusual I think.

Andy, I think you got it right when you mentioned that the water got into the bearings and ruined them. I think the saws with the bearing inside the hood will all have this potential problem. I have a Harbor Freight brick saw www.harborfreight.com/10-in-25-hp-tilebrick-saw-69275.html (cheaper when on super sale!) that I use outside with water and RV antifreeze for hacking big stuff up and for carving off chunks of attached matrix. Works really fast/well, even if it is very wet.

Ah, the sadness of someone passing or other tragedy before they got to use it. But it is good for you Roy as I am SURE it will be well used now.

A frequent problem. It has been discussed several times on here (hopefully you will be able to find the posts). Basically though I have found that when I glued a piece of truck inner-tube inside the lid it fixed the problem. For several years!!! Hope this helps.

Gosh Rob Jugglerguy, those pictures are from like a billion years ago . You should post those pictures on your kids' facebook wall. They would love you for it. JK Isn't it great to see how utterly cool your kids were, and proud of where they are now. Haven't heard much about Bryan's rock or unicycle exploits lately. I once publicly shared a picture of my daughter when she was young, and it ....wasn't well received by her, ha ha.

Those crosses are really nice. And you did a great job on the McDermitt opal. It is pretty soft and often want to disappear in the tumbler!
Is anything turning green up your way yet? Long winter.

The freeking hardest lizard to capture ever! Beautiful, intelligent, alert and fast. Another favorite! Thanks!! I can agree with that for sure Scott. This particular fellow I have named "Buster" because of his attitude. He waits by the steps and hunts insects. Darts away whenever I get too close. He is slowly getting more tame, allowing me to walk around him. The dang Roadside Hawks have cleaned out many of the reptiles around the house, but ole Buster is too clever and alert. And fast!! And I have seen a couple others of his species now, so he must be reproducing.

another from Panama. One of my all-time favorite reptiles! A yellow-headed gecko (Gonatodes albogularis) all lit up. One beautiful lizard !! Love the blue eyes.

Well, it is kind of a timely thread resurrection since there is now Howardite available . . . I saw quite a bit at Q this year and last year. Pricier even than 2009, but it's out there. Hmmm. Was it Howardite, or the more common (Royal) Flamingo Agate?

Susan, great start! I will be watching with great interest. Bravo for your courage to do this.
A couple tips that might help. 1) cut the class with a glass cutter. You won't get the chipping on the edges from the saw blade chattering 2) sometimes it helps to prevent micro bubbles by actually putting a coating of epoxy on both pieces before you slide them together. Sometimes bubbles want to stick to the dry slab/glass and by putting a coating on both and allowing them to set upright for just a short bit, bubbles are less likely to occur. Yes, you will get a lot of waste epoxy, but it is important to be generous to prevent bubble and the waste goes down with experience.
You are doing great. I hope the piece isn't too tall with all the layers.

Yes, that is the one. Okay, it is obvious now that it is coral. If it is hard enough you might get some nice cabs. Thx for posting.

Nice! Should be some great stuff to work with. I thought them calling that brecciated mookaite was pretty creative. Could you post a closeup of the one in the upper right of this picture? Looks like an interesting petwood/fossil.

Hardness of Ceramic Tiles "Water absorption rate, glazes, compression and material all determine the hardness of ceramic tile The percentage of water absorption by the tile body determines whether the ceramic tile is Impervious, Vitreous, Semi-Vitreous, or Non-Vitreous. From Impervious, where absorption rates of 15% and higher, hardness factors change Most glazes fall in the 5 to 6 Mohs Scale range. However, certain types of floor and porcelain tiles can have compressive strengths of 10,000 PSI and a Mohs hardness factor of 8" This is right on James. I have had great success using broken ceramic tiles to make my own tumbling ceramics which saves a LOT of money. Breaking them into the right size pieces is a hassle and danger(use glasses and gloves!!!) And choosing the right tile is the key. Since it is only one or two tiles, buy the highest quality porcelain (not just any ceramic) tile you can get. They usually are harder. Or ask the salesman. I have run tests of purchased porcelain media with my homemade and they wore at the same rate and worked the same. I did get a cheaper/poor tile once and it worked okay, but did wear pretty fast. So I figured it was softer and discarded it. I run them by themselves for a day or two to wear off the sharp edges a bit. The edges didn't hurt the rubber barrel at all. Hope this helps.

Look good Rob. I think you nailed it on the idea that the vibe does flats extremely well, while the roller does rounds really well. The one you ask is it Montana - I think might be AZ petwood. It doesn't look like the Arizona pet wood that I did for the world rock tumbling competition. This is transparent, but that was opaque. I don't have much other experience with Arizona pet wood though. I have quite a bit that looks just like yours. I think there is a fair range of opacity.
