Anyone have an HP 10" trim saw tank/arbor that they're looking for a table for? This looks like it's from an E2, but would probably fit the e5 etc...
Also have another trim saw table top, not sure what it's from, has a unique set of oil drain grooves, maybe someone will recognize. You pay shipping, (send me a rock - though that part is optional)
second table, feels like an 8" saw, but not sure.

I bought 3 of the Kingsley North cheap 20" blades for 37.50 each. The first one I used made 242 cuts, mostly Brazilian and a few geodes and Petrified Wood pieces. That comes out to about 17 cents a cut. Will be curious to see if the 2nd blade can last as long. I do do have one purchased clamp and one custom built clamp I always use to secure the rocks. A slipped rock in the vise seems to be the biggest enemy of a blade. Brazilians should be about the toughest test I can think of. Looks like the 20" MK is 12x the price of the notched rim, hard to imagine getting 2900 cuts out of any blade? Thanks for that data point.
Gotta go get some new superballs for the vibe

oregon Rick, that's a spectacular specimen and it deserves the vibe. You really lucked out finding such a good one during your short trip to the coprolite fields last spring. Eta... Wow, I just continue to keep coming back to look at this specimen because I find it so beautiful. I notice some nice fortification lines in the agate and wonderful lightning patterns that are far above average. Truly an exhibition grade specimen and very glad Rick ended up finding it.
yes there are some fortifications, almost a tiny druzy pocket. I still have a hard time 'reading' the outsides of these, but that keeps it interesting. This one was very smooth, and glad I went through the bother to mount it to get the big face cut down the middle of the paddy's 'thin' direction.
Thanks again for the help, wouldn't have happened wo it.

That is a very nice specimen. It would have already pushed to the front of the queue for Vibe-Lap!!! Slightly off topic, what type blade and what size did you cut this with?. If I did not know better it looks to be one of the Kingsley North bargain blades. This was on the shop's (Genuine, vintage, real?...) 24 in HP, I'm not sure of the blade. In the picture it looks like one of the cheap 'krinkle' blades but I think it actually is a segmented blade if I remember correctly. Pretty sure we've swedged it a time or two, and wouldn't have done that on a 'pressed' blade.
I saw the price of those too last when ordering a 12" blade for the shop, I think they were about 1/10th ! the price? I should look if some other thread here has assessed them vs an MK (things don't always get treated kindly in a public space)

child hood pranks might deserve an entirely new thread, we'd probably all be arrested several times over these days... meanwhile, finally went for a large turd, one near Randy quality, might have to fire up the vib lap...

a Nelson 1820 followed me home the other day, impressive.
The lid won't quite shut in the front, since the tank top half is 1/4" steel, I don't think that's changed. On the back of this lid is welded a "U" flange of sheet metal, that I'm guessing was sort of a spring to wedge behind the tank wall and the inner lip of the lid as it closed and keep oil from escaping out he back? in the pic you can see a slight gap between the inner lip lid and this 'sealing sheet metal spring' I'm wondering if this was an original Nelson feature of if someone added this on. On this saw it seems like the "U spring" would have to be clamped fairly flat to make the lid close reasonably well?
or thinking more about it, was this addon piece supposed to be flat/straight and extend further down into the tank, maybe it got bent by accident?

Definitely needed a good cleaning. Took a couple of hours, but the barrels are in great shape.
Good you could see through the rock snot... Not like I really *need* another tumbler, but enjoy trying different machines out.

Looked for a UV-18 for a couple of years and everyone was sold out and could not even find a used one. Finally picked up a new one I found at the last booth I went to. Then these were posted on here being sold on Ebay. Rather dirty and rough looking but I figured still cheaper than even buying one replacement bowl, so I figured parts if they did not work. Was out of town 3 weeks so just got them cleaned up and checked and sure enough they both run fine. One is missing a spring so I have a couple new springs on order. And want to get some wing nuts for the top. Still very happy with the purchase. Forgot who originally posted these, but thank you.
I guess the person added shipping a few days after first listed, I went back excited, but you must have already bought them! Ah well, if you ever figure two is three are too much let me know. Glad to hear they were in as good shape as I figured they were.

Thanks for all the swag Wooferhound , arrived all intact. Love the bumper sticker, I once got called a rocket scientist, I've kinda kept that on hand often when explaining seems to difficult. Some friends will get a great kick out of that. (n*365) + (n/4) days old today, so good timing!

geoinfo.nmt.edu › 201...PDF The agates and geodes of northern Chihuahua and southern New Mexico This is a wealth of info and while I'm here, not to hijack, but does this look like any of the Chihuahua agates? or anyone recognize it? I'm calling it Mandelbrot

From the looks of them, I'd say they look like they have been rode hard and put away wet! I wonder if they really work. Seems like if a person wanted to sell something they'd make it look appealing. Jim I'd venture from what else he's selling, these were in an industrial shop (they are the industrial version) and who cleans up at work when you don't have to. There are also those of us who have shiny rocks, but not-so-shiny workspaces ~$500-600 for new clean one, if you can find one that is.

Not mine, but the seller doesn't seem to want to ship so someone should get these at $60... And if you wanted to send one north I'd be happy to cover shipping...

Running out of excuses to not work on an old HP 24. It has the large top window that needs replaced. Cutting a rubber/felt one pc gasket is not an option. What do folks recommend for gasket sealer? Some sort of oil pan gasket stuff should do the trick?
Thanks.

There was blue on the inside some will question if it's ellensburg blue or not but it comes from the tanaway basalt above the fluvial plain that ellensburg is below. That sounds like where the Ellensburg blues come from as I recall. if you have time, check out some of Nick Zentner's videos on Ellensburg blues... kinda addicting to start listening to his geology talks...

Thanks for the update Dave! I've got a couple places I hound that I know pretty well that don't have cell service...but I won't be going out there for awhile. When I do, I'm going to try the other one's out to see how they do. If you find something you end up liking, please let me know. As we started this discussion, I've been on the 'net a bit and Google Maps seems to be at the top of the list for stuff like this (offline maps). If you end up going the Onx route (they do have a free trial if I recall), I'd love to see your feedback. You can Check out Avenza as well. I think they patented putting Location data into pdf's, which has unfortunately stymied the competition. Still the free version isn't bad, works without cell service, lets you have three maps currently active (I store the others elsewhere on my phone, load them when needed) there are lots of free maps available from the store (all of the USGS quads etc), and lots of governmental agencies publish free geo-referenced pdfs as well that work with this. (you do need some kind of connection to download maps) Offline satellite imagery is a bit tougher.

So, since i'm back in town until tomorrow, my dad and I decided it would be a smart idea to go explore all of the rimrock where the Bat Cave jasper was found. We were hoping to find some new deposits or unfound material, but unfortunately fell short. Making the long steep hike to the base, here is the beginning of the rimrock looking north to where the bat cave was found. No more gate across the road? That seems like an ongoing battle at that site...

I see your point oregon . Good catch. The Institution for Creation Research article is highly generalized and void of many points found in the much more detailed Nature Paper. I was able to interpret the Creation Research article, lol the Nature paper quickly exceeded my educational limits. I would be very interested in how the omissions in the creation article affect the conclusion of this subject in layman's terms. I think the Nature Paper is saying that this particular animal has been known to have communal outhouses and that this behavior is not necessarily related to being corralled by a flooding situation.
Yeah, This happens a lot. Referencing a peer reviewed scientific article to lend credence to entire speculation, unrelated conclusions. If it's on the internet is must be true. The Creation Research hypotheses are a load of dino crap ihmo. Nothing personal, I'm sure you can appreciate.

I found a coprolite deposition scenario that may interest you Randy. It suggests that a group of dinosaurs of all ages were corralled by high water on top of some hills and did their business there being surrounded by rising water(suggesting the Biblical flood or a flood). They were making deposits at rates of up to 80 turds per square yard as if tightly packed together (and perhaps in an accelerated rate fearing their pending doom of being drowned !). In Argentina silicification is so rampant due to the vast volcanic ash fields. The deposit of feces was then silicified in place with their flat bottoms pointing down suggesting their original deposit placement location and deposit patterns. hmmm. There are many new scientist that are finding merit in the Biblical flood. This article is one of many other similar subjects in a video catalog. www.icr.org/article/digging-into-fossil-outhouse/A PS: "The Chañares Formation also left another surprise. Not only did this rock layer contain concentrated areas of fossil dung and the bones of large herbivores, but it also held the remains of a fossil ray-finned fish and crocodile-like reptiles." Could it be the crocodiles were feeding on the drowning dinosaurs ? Could have been a yum-yum moment for those denisons...Just like rising lakes attract fish feeding on fresh morsels as the water rises into dryer land.
Interesting read of the Original paper, not sure I'm on board with the "Institute for Creation Research" interpretation.
Abstract
Defecation in communal latrines is a common behaviour of extant mammals widely distributed among megaherbivores. This behaviour has key social functions with important biological and ecological implications. Herbivore communal latrines are only documented among mammals and their fossil record is exceptionally restricted to the late Cenozoic. Here we report the discovery of several massive coprolite associations in the Middle-Late Triassic of the Chañares Formation, Argentina, which represent fossil communal latrines based on a high areal density, small areal extension and taphonomic attributes. Several lines of evidence (size, morphology, abundance and coprofabrics) and their association with kannemeyeriiform dicynodonts indicate that these large synapsids produced the communal latrines and had a gregarious behaviour comparable to that of extant megaherbivores. This is the first evidence of megaherbivore communal latrines in non-mammal vertebrates, indicating that this mammal-type behaviour was present in distant relatives of mammals and predates its previous oldest record by 220 Mya.
