Okay, I admit it, this is really just an excuse to post some pictures as I don't have any new tumbled stones to post but felt like posting something anyway.... I seem to have an obsession with trying to tumble "larger" stones, which sometimes works out well and sometimes doesn't. It always takes longer to smooth out the big ones, so much so that it can seem glacially slow. So to convince myself that this piece of petrified wood was actually changing, I began to take photos of it after various runs in coarse grind. I thought the time-lapse effect was kind of interesting. All pics taken dry: I didn't take a "before" pic, but here it is after 8 days in coarse.  This is after 16 days.  24 days:  32 days:  Skip ahead a bit to 50 days:  This was run in a 6 lb barrel with a mix of other things. I did run it for another two weeks but I didn't take any pics of that. I never did manage to obtain a perfectly blemish-free stone, but I think I ended up pretty much as close as the material was going to allow me get. |

Oops, I messed up and posted the 8-day pic twice... I just modified the post to include the proper 16 day pic, so now you should see some change from 8 to 16 days.  |

Time lapse photography is amazing!
That is a nice progression...is it petrified wood?

That's pretty neat, very nice piece of pet wood too. You take great photos, they really loaded fast for me on my old slow dial up. Please take more as it moves through each stage.

Thanks for the interest. I feel a bit sheepish here, as I had a lot more pics but deleted most of them, and these here are most of what I did not delete. I was monitoring 4 big pieces of petrified wood a few months back, taking photos of them on all 4 sides every time I took them out of coarse grind. So I was adding 16 photos to my file every week and it was quickly growing unwieldy. Once I could see the end was in sight I stopped taking pics and deleted almost all the pics I did have, with these ones here being my most complete set of leftovers. The stones are now heading through the finer stages, but I haven't been taking pics.
Since this seems to be something that some people are interested in, I'll try it again with two more big pieces of petwood that I hope to start up in coarse within a week, and maybe I'll focus on taking pics of just one side of each stone so that the file doesn't get out of hand. Well, maybe I should first wait to see if the current ones turn out okay, but I won't know the results of that for another few weeks yet.

Alice, yes that is 50 days, then I ran it for another 18 days in coarse to try to smooth out the remaining rough spots (no pics of that though). Of the 4 pieces of large pet.wood that were run through (first in separate barrels, eventually combining them into one barrel with a lot of much smaller stuff), they ran anywhere from 52 days in total for the shortest, to 70 days for the longest. I still didn't think they reached perfection, but you can probably understand me thinking that enough is enough at that point.
