...and if it doesn't polish, no sense in cutting any more. Got it. Thanks.

Hey , we were at that mine and the falls . No fishing though . Lake of the clouds a couple times also . No , I won't give away the name of the mine or falls Its in the Pork. A couple more mines in there. All are rendered people proof. The great legend is the Ojibwa woman that had a silver mine east of the park. She would leave for a few days and return with a load of silver. There was a silver rush of sorts, the town is called Silver city. Someplace around I have a piece of beach rock that appears to have a couple of silver specks in it. My rock, my story anyway.

Thanks.
I have heard a late snowfall, a lifetime accomplishment for some areas of the country, fixes N. I wondered where it came from. The N, I know a thing or two about snow.

It's called a "window". And Nice!! Well done! The window is the first slice. Window because that's when we get the first glimpse of the possibilities, or lack there of?

No, I have the "gift of gab". A nice young lady went through the trouble of picking it from a bin for me. I may send her a flower. Its from Madagascar. There are several more, not quite as nice.

It has been known that rock powders improve soil for better plant growth. I recall an author wondering how long it would be until folks fertilized their maple sugar bush trees with rock powders.
My great wonder is what mechanical or chemical action/reaction fixes the nitrogen in the medium.

It will be awhile before I cut. I am anxious to get at it. Packed for a move, recovering hernia surgery. I may head to the local club to use the saws there. I will let you know.

What makes this spot cool is the old mine that was here. Just behind me, I'll turn around. It used to be nicer before the state got possession of it. There was a yellow birch there, you can see the stump. Then there needs to be signs and fences. The shaft is full of rubble just out of sight. In the mid 1800's the Italian imigrants were the stone masons. Has not been mortar in the joints since before any of us were born. The rock is basalt from the mine.
A quick fish through the 'Bedspring hole' finds no fish up this far yet. The name comes from the broken poor rock in the riverbed grabbing your bait. We need to drop back down and get to my favorite river. For a mile or so of river its all busted and tilted shale. Stay on the lip and have felts on your boots. The silt is greasier than a fatman eating cold possum, you will swim. The water is about 40 degrees. While your dip and return to the truck will be memorable, you won't like it. There are fish here. My no good for hunting fishing pard does point them. Saves time. I manage a couple of small ones. I am purely a fillet and release kind of guy. I hope my hunter/gather lifestyle doesn't upset you. If it does, I just let out a sigh for you. Peace.

This trip took place a couple of years ago. I am recovering from surgery now, so i cannot take you on a new one. But its only a rerun if you saw it somewhere else first. The trip took place in the west end of the UP. The streams and rivers shown are Lake superior tributaries. We start out by just cruising along the Lake. Its pretty early in the season, so no tourists scurrying about, trying to exceed the speed limit. And tailgate to the point of pulling over to avoid the aggrevation. A few miles 'up' the road and we are several hundred feet above the Lake. Just behind me is a poorly planned mine shaft. To the left of the picture is a poor rock pile. Lots of low quality basalt bedrock there. No trip to the Porkies with out a visit to Lake of the Clouds. Off to the left, some distance down the escarpment, Peregrine Falcon chicks were hand raised by grad students wearing peregrine mommy puppets. It was pretty cool, but the birds seem to have reestablished themselves. Some towns are putting up nest platforms to biologically control the feral pigeon population. Well, enough of checking out the sights and lets drop back down and find some fish. We are looking for Lake run rainbow trout, some call them steelhead. That raises the hackles on the Pacific northwest fisherman, "if it don't go to sea it can't be a steelhead" I call them rainbows. First stop is a small trib, water is too low. Other fisherman have taken or spooked whats here. Moving on up. Next stop is several miles inland. This little falls slows them down, when the water is right some fish make it over them. Not sure how long a post can be, I am saving and continueing.

I like solar for small applications. I have 2 marine battery power packs- each with it's own portable folding solar panel. When we camp or whatever, or lose power, it is quite enough for the router, laptop, lights, recharging, 12v fan, etc. They have come in handy many many times. How do you get AC from your battery?

Too soon here. End of May(be)? In the land of no poisonous snakes or widow spiders winters give up slowly. There must be a trade off somewhere.

Thank you for the pictures and knowledge. Most of our snow and ice is gone. One needs to wait for the bugs to start feeding before heading to the fens and looking at the pitcher plants.

Be nervous, get your son anticipating the out come. He will learn patience from your ability to see this through. Its really only rocks, what can you do to ruin them?

Springtime. Birds return, snow melts, and even old men get a gleam in their eye.

Here is a piece of jasper I have. There is approximately 3/8 of an inch of rock needed to be removed to get a flat surface. Not sure what its called, but in saw mill vernacular its called 'opening'. So when I am ready to open this piece, should I open to just face it flat and have a little bit of 3/8 inch tumbler fodder, probably only useful for the smalls needed to grind? Or do I open deeper to get some pieces that may be something when done in the tumble? Or do I send it to you because you are a great person?

Some short time ago, I purchased 10 pounds of Botswana agates from GeoShops. I really liked most of them, so I went back to the well and ordered another bag. I also ordered some other stuff I really didn't like. I himmed and hawed for a bit and decided to return the other stuiff. I asked if I could exchange this for some more Botswanas. All the while thinking I was $4 or so short on exchange price and then the postage.... the box of Botswanas arrived today with a note that an even exchange was done. No postage charged.
I could not be more pleased with the customer support I received from them!

I am far from an expert, but I will try to help.
How much rough? I think you are confusing the term grit with rough. Rough is what the rocks are also called. They may also be called 'tumbling rough'.
The rocks (rough) should be of different sizes. The drum level of rocks you specify should be ok.
I am not sure on the amount of grit to tell you to use. Two tbs should be ok. There seems to be a theory on this site that the companies are that sell the grit are the ones telling you how much to use. Common-sense would indicate too much grit wastes money and too little grit wastes time. I do know you should keep notes on what you do, grit breaks down fast, and you need to form a slurry.
To deal with grit breakdown, I add a tbs of grit mid week. But maybe I should add two. Keeping notes, I am, to see what I like.
To aid in slurry formation, I am using cat litter. I had some from another use. My camp has good red clay. I will be gathering some and substituting that for the litter. I do know you need to keep an eye on slurry thickness. Cat litter is designed to absorb water, you may need to add water at first. For a long time people did nothing to aid in slurry formation. People experimenting and sharing their results can make a difference.
I think too few of rocks in a package is why the canned vegetables are less than 16 ounces, a pound package of bacon is likely no longer a pound. Not sure if it could be called corporate greed, it is driven by the bottom line though.
You may find out agates are not done in a week. A clean out and recharge is probably whats needed.
I wish you the best with your son. If no one has ever told you this, let me be the first. "Blink twice and they are grown and gone" You only get one childhood with them.

Would you share those values? Your success is notable and those values important. Please and thank you. I am at bowling tournaments with my kid all weekend but will report numbers when I get a chance. Did you ever request the speed calculator I made in excel? Chuck I think there is an error here. By my calculations you are much closer to 37 rpm at the barrel. When figuring pulleys and speed you need to use pitch or datum diameter. Going to Grainger catalog, I find a pitch diameter of 1.05" for a 3L belt and a 1.5 inch pulley. A 10 inch pulley shows 9.55" for the same 3L belt. Plugging 1.05 for drive and 9.55 for driven I get 190 rpm (rounded up) barrel shaft speed. 190 rpm at .75 onto a 3.875 barrel results in 38 rpm (again rounded up). Not being a tumbler very long, but currently recuperating from hernia surgery gives me time to glean much information. I would venture a guess that a 38 rpm 3 7/8 inch barrel would increase the time needed to properly shape stones with coarse grit. I believe you are vibrating your final steps, but to follow through. A slow speed rotary tumbler should give a nicer polish if given the time needed. Might I suggest a 2 in pulley at 1.55 pitch, again the same 3L belt, to achieve 54 rpm drum speed. I chose the 3L belt for these calculations because there seems no need for a heavier belt to run a tumbler. Using a 4L belt changes things.
