You and I both MsAli! I got my set last week. Just had to set them aside for now. My first goal is to get together my pieces for the traveling box. Then I can start to think about these. From what I read, we can grind before we tumble. But once in the tumbler, we can't ever grind again? Is that what you thought too? Usually I just toss material into the tumbler for the course stage, then grind anything that needs it after the initial few weeks.

That is how I interpreted it as well. No grinding after they start tumbling. What did you think of the rocks? I was kind of disappointed. It will be interesting to see how they tumble

Got my rocks yesterday. They look similar to Alikat's. There's some good ones in there I think. Also some that are head-scratchers. I'm not sure on the grinding. I know you can't grind AFTER the first stage is done. I'll have to look at the fine points of the rules. Personally, I don't have to worry about it for a while, as I tumble outside. Right now, almost 2 pm here, it's about 16-17 degrees F with a stiff wind, so a wind chill of around zero. And tonight, it will be cold.

I think that's how I read the rules this year also (on the website). Did they send the rules under the mailing label this year? That's what they did last year. I didn't look for it yesterday, as it was late at night when I got home and I just wanted to see the rocks. Put yours in some water to get a better idea how they will look. They look like a more promising bunch to tumble than the ones we had last year.

I have one that is just beautiful, the white one in upper left with pretty pink and a couple that have real potential but the rest are meh... I seriously thought at first it was a box of different types- I don't think I will do a lot of pre-grinding.

If you smack some of the bigger ones in half you will have twice as many nice ones.

From what I read, we can grind before we tumble. But once in the tumbler, we can't ever grind again? Is that what you thought too? Usually I just toss material into the tumbler for the course stage, then grind anything that needs it after the initial few weeks. Hmmm, I'm thinking about this. Better make a decision in the next couple of days. I happened to read the rules, and it's not clear to me about grinding. On one hand it (appears) to read that you can remove imperfections by grinding before or after the rough tumble, but then they seem to say no grinding after the tumble has begun. :confused: " Applicants are permitted to remove (before or after your rough tumble) spalls, chips, cracks and any other imperfections on a grinding wheel. After this initial cleanup, the rock must be allowed to go through and complete the tumbling process without any further handwork. No hand polishing or grinding is permitted after the tumbling process begins and after completion." So which is it? Are they basically saying you get ONE chance at grinding (before or after the coarse stage) and from there, no further work can be done on them? Chuck Drummond Island Rocks or Rob Jugglerguy , do you have any insight on this? Thanks. Dave

I think the idea is that the rocks have to be polished by tumbling rather than by working them on wheels. Since it says “before or after the rough tumble”, I think it’s definitely allowed after the tumbling process begins. After any grinding, you just have to go through all tumbling stages to produce a shine. Some rocks are very difficult to tumble, but are easy to polish by hand. For example, the Petoskey stone in my avatar was done by hand, not tumbled. It is very difficult to achieve the same result by tumbling a Petoskey stone, so hand polishing would be unfair. That’s how I read the rules.

It would be impossible to police when pre-grinding is done. As long as the rocks go back into stage one grit after grinding you are basically starting over anyway. My opinion is no harm no foul.

For example, the Petoskey stone in my avatar was done by hand, not tumbled. It is very difficult to achieve the same result by tumbling a Petoskey stone, so hand polishing would be unfair. That’s how I read the rules. Well, not knowing you had replied, I had just gotten off the phone with the contest coordinator to get clarification. And, I think you're saying the same thing. According to "Lori," all grinding and such needs to take place before/during/after the coarse stage. It's simply not a "one and done" type thing. As long as all modifications (grinding/shaping) takes place before moving rocks to the 220 stage, all is good. In their view related to the rules, the "tumbling process" begins at the 220 stage. Everything else before that is just prep work. That was my interpretation of our conversation, and I repeated it with her. So, based upon our discussion, there appears to be nothing wrong with grinding before coarse begins, evaluating rocks and grinding again in the middle of that stage, and then moving on from there. After the coarse run, the rocks can't be touched by a wheel. I appreciate your input. Just still deciding whether or not I have the discipline/patience to jump into this. I also realize my model T (rotary) won't ever match the formula 1 racecars (vibes). Thanks for the help, Rob. Dave

Dave you should totally do it. I'm using a 3lb harbor freight, and have no clue what im doing. But I do love a challenge. Maybe, we can have a mini contest between us😊 And THANK YOU for calling Lori. I was going to do that tomorrow, so it saved me some time and helped me so much.

I was going to do that tomorrow, so it saved me some time and helped me so much. I'm just questioning my devotion to such a task. Lately, I've taken the captbob route of letting things roll along without a timeline. I've been lazy, and I've gone as far as not photographing my last couple of batches. My motivation has been low lately, so I'm not sure if I want to do this. I know I'm just in a lull right now, so we'll see what happens. At worst, I buy some rocks and roll them. We'll see what happens...even though I have to decide very, very soon. Dave

I'll add some more pictures.
