usually hard to burn up the coil on those motors. Does the shaft still turn by hand easily? if not take it apart and clean it - though it does looks like a loose wire loop in some of the pictures? You could test the coil for continuity/resistance as well. good luck

Picked this up a little bit ago. My guess is there is a small table attachment that's missing which the lower bar lifted to meet the drill? Anyone remember one of these or have an old Griegers catalog?

Yeah, I finally used up my stash refurbing folks QT tumblers. the original belts I had were Optibelt, vb 6x375 mm .
I've purchased a few sewing machine belts for folks: MB390, they're much less expensive, proper dimensions and seem to be holding up ok, but don't have many data points to go on. I also have some 6mm Poly urethane belt to make my own, but haven't found anyone to try that out for me yet. There's also the option of 3d printing with TPU - will try that sometime.
$15 for the original belts seems a bit excessive.

The question I have is which blades to buy now?
Not sure about all the implications in the video: The PPP loans sound like the same level as many other businesses. I'm guessing the lapidary end of their business was small compared to construction. Maybe they were just demolished by the pandemic? Chinese competition in the Diamond abrasive space? I don't know, but there isn't anything out there to imply they were scheming to screw people over at this point? Happy to hear the story if anyone has real info.

You did the knob on a filament printer? I have been looking at 3d printers and wondering how well the filament printers can do threads. They look really good to me.
modeling is easy, those are perfect. Printing has many variables. You can use a super fine nozzle i.e. 0.1mm but printing time increases. The robotics team printed quarter scale servo splines, eg 25 splines on a 1.4" hub with 0.4 (default) and 0.3mm nozzles and I was impressed. So yeah super fine threads are tough, but you can always run a tap through as well if you print things smaller.
for this knob, easier to print two flat surfaces and join them rather than worrying about removing support material. Lots of decent printers to tinker with for not a very large investment these days.

Rainy day project today.
Cover for a qt12/66/6/NR and a knurled knob (where do they all go?) Files available for download
have to swap filament and try printing some TPU belts, let me know if anyone has experience with printing belts.

Anyone think this is likely to be Indonesian Orbicular Jasper rather than Ocean Jasper from Madagascar?
Q: What about "Ocean Jasper" from Indonesia? A: The Indonesian orbicular material does indeed have similarities with a subset of Ocean Jasper, namely multiple-ringed spherulites and spherulite tails, vivid colors and translucency. A few example specimens are shown HERE. There is a concerted effort from dealers in Indonesia to brand their orbicular rock "Ocean Jasper", even though in the last 10 years the material has been sold by U.S. dealers under the name "River Jasper". Despite the similarities, this material is easily distinguishable from Ocean Jasper, as the Indonesian spherulites have a characteristic homogeneous oblate spherulite that is limited to a much smaller size, typically 2-3mm, and the zoning and pattern formations are far less complex or heterogenous.

The spring on the ls10 went from the split screw arm to a brass slack adjustment bolt if I remember correctly. The HP Lapidary saw is still pretty much a direct copy, see
I've helped more than a few saws who's bolts have fallen out into the primordial soup, good to have a tight stopper nut on that. good luck.

So is the mold just a welded box of mild steel, lined with 1/8" fiber paper and set atop other paper? No problems with glass oozing out the bottom? seems like you had some stainless? molds that bolted together.

hmmm That saw quickly moved on to a new owner. Been a while and don't remember all the details.
I think the spacing is all dictated if the snaprings are in place and the bearings are well seated AND STAY THERE. there isn't anything to keep the bearings from working towards the end of the shaft besides the press fits. Think that I fit a 5/8 lock collar in front of the blade side bearing, probably good to do both ends or push the pulley snug to the bearing on the back? Good luck with it.

I don't usually weigh my rocks. But wanted to do an experiment so I did this time. My 5lb bags only weighed around 4.106. Is that alot missing. Should I be concerned about it?
I'm guessing that might be 4 lbs 10.6 oz on many digital scales? or 4.7lbs, at least that's closer to 5. At least I've often seen folks make that same mistake with the scale I use, the tiny little lb indicator looks like a decimal point. But then again might be some scales that think you need to be accurate to a thousandth of a pound.

Been rehabbing tumblers for a few years, picked up a box with a couple dozen QT belts a long time ago and down to my last one. $10+shipping if you can find them seems a bit steep.
Thinking of making a round Polyeurthane version or printing a TPU one, just wondering if anyone has longevity info if they've done that.
Thanks.

Just to follow up....
I was wondering if I'd know any of these faces, did a little bit of record searching last night.
So it looks like Jordan Willing owns several import companies headquartered in Ashland, One of the principal ones selling STEM toys to children. Ironically featuring a lot of National geographic endorsed items. What a great example to send to kids. thinkbluemarble.com/our-story/

The National Geo article has a few more pics, but yeah the scale of this is mind boggling. Worth trying to get a handle on where your bone comes from I suppose. Wouldn't be surprised to see dino bone trade go the way of ivory etc.
Edit - sorry that's behind enter your email to view link... not too much other info than the Deseret News above,
don't want to post copyrighted photos/stories, but there are pics of shipping containers full of rocks and some gembone pcs, (with a $4500 price tag) as they were trying to id locations using radioactive isotopes.

Let me know the spacing between the bolt holes on top. I have a HP table, but thinking it might have been from a 10" saw? not sure. Oh wow, that's really cool! I just measured it and looks like the four bolt holes are about 6 1/4" width and 8" length apart. But as Rockoonz mentioned, even if it's close, I could probably make it work. Thanks!
how far from the 8" line to the blade?
