Thanks, that's really nifty. Not sure all that engineering was necessary, but cool piece of kit. Thanks for the video.

and arbor that oscillates up about 1/4 inch about every second to speed up the cut.
Any further explanation on the mechanics of this? Does is jog back/forth ie, one edge of the blade is doing the bulk of the cutting?

Keep in mind it’s a 1.5 ho motor You will need a relay rated for that inductive load. Yep, I'd suggest lulu take it to someone who knows what's going on, not stuff to mess with if you don't know what you're doing. I think you've all mentioned enough cautions. 1.5hp is extreme overkill imho as well.

and if you want to skip oil baths (single pole relay would also be fine. )

So is it worth a trip there to collect if you only had a 'few' tools? Sounds like the best stuff came from the jackhammer's cast offs. I fly back to the general area occasionally to see family, but it's not like I'd bring a bunch of tools with. Just wondering what's the honest opinion of whether it's worth going by and essentially surface collecting from either of you Jugglerguy holajonathan or anyone else that's been there in person...

What about Zelle? I kinda like that its backed by a bunch of banks rather than paypal, but I haven't used it yet.

My absolute rarest material, to my knowledge, is the small pile of slabs of poppy jasper from a single piece found in the Skykomish river on the Olympic Peninsula in WA. A fairly short lived Ebay slab seller knew the person who found it, slabbed it, and sold the slabs for them, I was able to score several slabs, plus I bought her end cuts. Here's the only cab I've cut from it so far. Do you know what the host material here is? I just did a quick run of a friend's orbicular jasper from that region, the host sorta looked like hematite, but different... 'bout time for another wander around the Olympics... hmm don't know why my upload isn't showing...

hmm interesting, my list is pretty similar without looking
1. 80 2. 1000 3. 80 4. 1000 5. 1000 6. 1000 7. 80 8. 80 9. 1000 10. 1000 11. 80 12. 1000 13. 1000 14. 1000 15. 3123 gms

oregon - Thanks for posting the original link to the saw parts. Now I just have to wait to see how the original one stacks up against my imitation.
Peruano - I'm gonna' have to try the bearing swaging trick someday. I remember hearing that discussed some time ago.
some of the other parts were for that saw also - I think the 'slab guide'? looks like the ad is down, so maybe you got them all... fun to make the connection for a wayward part

Thanks, it certainly looks like that inside, not many pictures of folks' outside. These two just had a distinctive stacked layer outer appearance, must have been well cleaned/scoured by someone. Thanks.

I grabbed a pair of these at a sale because they looked unique (and they were the only two). Could barely see a bit of agate on the one I cut. I didn't take pictures of the other, but it's more rounded, with a dimple on top of the layers. Anyway, it was a surprise to find a void inside, as the outer layer lines give no indication of the bulge. Interesting formation, and unique enough that I'm sure someone know exactly where they came from and what they are. Thanks in advance!

seems more likely to be half of that 1800 (1750) rpm?

It's all simple ratios, so if it's 14 rpm now, you'd have to half the diameter of the pulley to get 28 rpm.
Calculations are never exact as belts will ride at different diameters,slippage etc etc etc, but in the ball park. not likely, but your motor could be 1050 rpm's too? download a strobe light app for your phone and put a tick mark on your motor pulley if you want to know the rpm. (can use it for the barrel too) I have strobily here on my phone, but there are heaps.

These motors usually draw about an amp, approximately equivalent to a 100 watt incandescent bulb. 18-14 gauge extension cords ('lamp cord') are spec'd for something like 10-15 amps. It's pretty cheap to make 'thick' cords by making thick vinyl insulation with thin wires these days... If the insulation is brittle,cracked etc it would be imperative to change it, a ground won't hurt, and 'thicker' cord will let you sleep better, but it's not like the original setup was way under spec'd. 2c.

spot welds from the bottom bracket to the frame must have broken, there shouldn't be a gap there.

This is my listing. I can take off the motor and base and ship it. Make an offer
