2017 Fun Cab Challenge This is a challenge to yourself... What is the best cab that you can create... posting the results of your creation whatever the outcome (just because the cab may not be the best please post anyway and if you like ask for feedback to improve). Theme chosen by prior month winner Tommy: Make a square cab of any color or material - bonus points (and vote consideration) should be given to a perfectly square concentric shape with clean 90 degree corners with minimal amount of corner radius, and a girdle of even thickness around the stone.Rules: All hand made cabbing techniques may be used. Cabs entered must be hand shaped (can be finished in a tumbler) and be completed by the last minute of the month in your timezone. They can be started before the month but only finished during the month. You must have 1 photo of ether a preform or slab of the rock. You can enter up to 3 individual finished piece (not combined) photos and 1 of the 3 photos will be used for voting to see what cab folks like the most (please note the photo you want used). You can change your photos or improve your cab and place new photos in your original post replacing old photos by the deadline. Finished jewelry cabs may not be entered (unless otherwise specified by the theme). It is OK if there is a hole drilled in the cab without a jump ring, as long as there is no extras on the rock (wire, chord, etc.) All entries submitted to this contest must be unique to this competition (not submitted in several different competitions). Any duplicates will not be included in the voting list. Feel free to share with us the story behind your workings or material. Also, don't forget to include the name of the material. If a tie occurs in the voting the breaker will be whoever submitted the finished item first. If there are any questions feel free to ask. Beginners to old timers are welcome. If you would like feedback (constructive criticism) ask for folks to pm you if they wish to offer tips. If you are new and think your cab isn't too good but its the best you can do post it anyway, getting feedback is how i got to where i am now! Prize : winner is allowed to chose theme for the month following voting, no physical prize yet. Read more: forum.rocktumblinghobby.com/thread/79085/june-2017-fcc?page=2#ixzz4mIKs7BlN

The word "concentric," which applies to circles, throws me off a bit but I think I know what he means. In fact I cut a square cab last night and I'll enter it as soon as I can get good images.

OK, I'll jump in. This is a square cab cut from unakite, sent to me by a Forum member. I had a small slab of it on my bench when I read about the contest so I decided to use it. The cab measures 25 mm. square and 5.5 mm. deep in the center. Slab Finished Square Side View Corner View Hope this is the sort of thing you had in mind Tommy!

Squares are my nemesis which is why I picked the theme. I will try again.

As I said before squares - and anything with sharp corners or tips are hard for me. I think it's because I'm self-taught and nobody ever showed me "do this, now do that..." regarding keeping uniform thickness of the girdle when dealing with corners. Consequently I tend to round everything just to keep the girdles uniform. So here is my entry. A customer just purchased a shattuckite cab from me and he had asked in advance if I could make him a a companion stone for it - same material, square, no bigger than 22mm, for a ring setting. I initially told him no and he bought the cab anyway - then I found this little scrap of the same material and made this. I shipped it as a free gift with his cabochon. It's not perfectly square - it's about a half mm off in size and slightly rounded on the edges.

Ok, here it is, it really can be done. The concentric square. The slab... Slabs... Cab... Yeah I know it probably doesn't qualify as a contender, but it fits all the criteria perfectly. The Willow creek is square to +/- .001", the bone white polka-dot agate also to the same tolerances, exact 90 degree corners, can't miss on a faceting machine. And the square is concentric in the only way a square ever could be. Sure had fun doing it, and got all the pics to do a walkthrough later if anyone's interested. metalsmith if your gray matter is twisted enough it's possible...

Rockoonz, that's an amazing stone. I'd love to see how that is done. I'm not familiar with the white bloodstone. Where does that come from? Is it a similar hardness to the basanite? Again, Very nice job.

Again, Very nice job. Bloodstone was my original plan, but the green didn't really go with the willow creek so I changed to white agate from the polkadot agate mine. The basanite is a bit softer but being a form of basalt is tough enough to not undercut, but as you can see it doesn't get the wet polish like the jasper and agate.
