Well ran across this Honey Hole a Couple miles up the shoreline where we have been going. In about 4 hrs we picked up a couple lbs of rock out of the surf. Its amazing how the waves are constantly changing the beach. We are going back Friday morning here are some pics and a short video. Cheers and remember ROCK ON! ~Duke YOUTUBE VIDEO SURF LAKE MICHIGAN >>>>>> or

the video did not open for me, just a head's up.
Beautiful granites. Beware that granite is a difficult rock to tumble finish. It is a mix of at least quartz and felspar. The softer felspar under cuts.

Guess I will be getting a baptism by fire. when you say tumble do you mean rotary or all tumbling methods? and If you could point me out the granite's and others please. Thanks ~Duke

Thanks ~Duke Not complicated Duke. granite easy to ID, granite and gneiss trickier to tell apart though. Georgia granites before and during tumbling. Re-melted(sorta) granite is gneiss and tumbles much better. granite saws and polishes on wheeled tools, but the tumbling process gouges out the softer(often pink) felspar. Vibe or rotary. One of the photos has darker gneiss on left, granite on right, in a SS pan for your ID assistance. www.flickr.com/photos/67205364@N06/16907934902/in/album-72157651560573935/

Duke, your beach is mostly sand! Yuck! Go find one with no sand, that’s where the fun is.
Are you finding any lightening stones? I’ve never hunted your part of the state, but I believe that’s where the lightening stones are found. They look pretty cool, so that’s what I’d be looking for.
I know you’re not really in Petoskey stone country, but can you find occasional Petoskey stones?

Yeah I found a lil Petoskey in that lode big as a nickle. What does a lightning stone look like? If you have several I would like to see them. Thanks ~Duke

I want to find some of that lightning!
From what most say granite is very challenging but beautiful if done correctly. I have tons of it, so am planning on learning how to work with it.

I have a ton of granite too! Very beautiful pieces. At this point on my Rock tumbling experience I am gonna have to go with what I have and find out what works. Kind of a baptism by fire so to speak. Cheers ~Duke

Cheers ~Duke My first tumble was granite. It gets shiny, but undercuts. I have made it a rule to not pick it up anymore, but I still pick up a piece occasionally.

Sorry I googled what Undercut Rock was cause I don't really know what your talking about. That Picture came up which I can understand so I had to be a smart arse! I really don't know what undercutting means in this case or what it does to a granite stone or what harm it causes. ~Duke

Undercutting is when a rock is made of different minerals and one is softer so it wears away faster. The hard parts of granite shine up nicely, but the softer minerals don’t shine and erode away more n the tumbler. If you look closely in the pictures from my link, you might be able to see that the black parts are like little valleys or holes in the rock.

You just gave me my YARD STICK lets see how my first batch turns out. ~Duke
