I made Cement - What's your Superpower? Over the past couple of weeks I've been running batches through my Lot-O with 220 & 500. Then I move the batch over to the Mini Sonic for 1200>TXP>#61 Rapid Polish. It's putting a good shine on things but last night I did a late evening check before heading to bed. The batch in the Mini was locked up tight and fairly dry (not completely). That was a first and a little annoying. It was in the second round of polish (1200). After a good soaking and 60 minutes of burnishing I put it all back together to let it run overnight. Then I observed it for a bit and noted that my load had momentary pauses or temporary lockups. There's a 10 second video of the pause but after attempting to upload it twice the system notified me that the video is too large. Anyone got a fix for that? So I pulled out a few of the larger rocks and let it run. This morning it was pretty dry so an additional 4-5 sprays of water and I left for work. It's still running now. I've pulled a few batches out of the Mini and noticed that they're quite warm. (I'll take a temp next time I notice that) So I'm wondering if my batch was too warm, too dry, too full, too neglected. I know for sure that it was too solid. What should I be looking for? I'm open to some suggestions, verbal beat-downs or anything that might help me understand my errors. Thanks, Mark I sometimes get lock ups in the mini. Most of the time I think this is because there are some larger or longer rocks that get wedged in. If this happens, I just take one or two out. The mini does tend to generate a lot of heat and dry out the slurry. I have always used more water than I think most people use in a mini and doesn't seem to affect the polish. |

Every time mine has locked up it's been because of too large of rocks. I regularly tumble too large of rocks anyway. They can get really tight when the lock up but usually a firm smack up side the barrel will get things moving again. Thanks rockbrain! When I discovered this lock up it was too late for a smack and a little early for the chisel & hammer!  Come to think of it there were a few larger rocks in that batch. Seems like I'm running a smaller batch in the Mini vs. the Lot-O. Mark PS: I like your signature! Funny stuff... |

The mini does tend to generate a lot of heat and dry out the slurry. I have always used more water than I think most people use in a mini and doesn't seem to affect the polish. I might have overloaded with a few larger rocks and they were certainly 'wedged in' as you mentioned. Tonight I'm using far more water than before. Maybe I'm doing a little too much of the 'Lot-O prep' by draining all the water from my batch before putting it into gear. It building a good slurry fairly quick so possibly a combination of rocks too big and way too dry. I appreciate the thoughts chris1956! |
