This fellow favorited some of my pics on flicker and asked me to join a little rock club (i think). What is going on with this saw? And his laps are big. Interesting tools. Hereis his flicker link. More dang cool tools and --German Thundereggs??

The swing arm has a clamp on the end and the weight of the rock drops it into the stationary blade. Simple but effective!

Another angle of the saw might be helpful. No link that I can find in the post.
As someone who has never cut or even seen a machine that you guys are using for cutting in person: it seems to me that the arm might have something to do with stabilizing a rather flimsy design and ensuing a blade that runs true to angle?

No link James but the saw is way cool. If you think about it the pressure on the blade gets lighter when it gets to the end of the cut so it would be less likely to bust out the last of the rock like my power feed does. Jim

Thanks for the explanations. Those laps are biggins. Looks like top notch workmanship but may be all home made stuff.

The swing arm has a clamp on the end and the weight of the rock drops it into the stationary blade. Simple but effective! Tony Yes, I am quite sure Tony had it figured. The one problem is that the saw can chatter, i.e. the rock is quite free it looks like to swing back. If the saw is too aggressive this can cause the rock to swing. But I am guessing that the feed (which is entirely dependent on the rock's weight) is quite slow. And it gets slower, and slower the closer to the arm being straight vertical. Conversely at first when starting on a rock it will be a relatively fast feed. Since the pivot point is behind the blades leading edge then it always will have a little angle and feed until the rock is finished. I would like to see this saw in action cutting an agate or something hard. Very interesting idea. Simple. Those German engineers, ha.

Interesting way to saw, seems to me like rigidity suffers though with the arm that far up on what looks like a fairly flimsy stand. Wish the other side was shown. Sure have some nice eggs.

Glad you guys are looking at this one. I felt the same issues Mark and Larry. But a well set up lapidary saw can cut very slow and smooth. Heck, the down force of the blade may stabilze the feed and the potential vibrations. I will say that saw marks are not acceptable with that many lapping machines laying around. Meaning that i think he polishes specimen faces - the most demanding cut to ask of a saw.

Notice the swing arm looks free to slide toward the blade as slabs are sliced. Y'all probably saw that but i just got it.
I asked for more photos.

haha! Agate from Friedrichroda in the province of Thuringen could just as easily have come from Richardsons ranch.

Well well. Those rascals have it together in rock carving. I knew they made agate handled knives for common kitchen use for many years Rick. As if it were rosewood. So it makes sense that they transcended into exotic carving. I knew they mined agate for semi decorative uses many years ago. But never thought about the technology they would bring to the table. Never knew it went that far back...
That dang saw may be very advanced in details of design. When i saw that it was German it caught my attention because of their mastery of machinery. The Japanese copy them..They are trend setters.Always on the leading edge of mechanical advancement.
I should look into ' Made in Germany' lapidary equipment. Those carvings are outrageous.

Double WOW! Just that small sampling is amazing! If the place is full of stuff like this, I think I'd have to spend about a week there seeing everything.
Carvers in the same house - genetic, or learned?

I'll defer to Kurt who I'm sure knows far more about this topic than me. But the term "house" refers to the tradition there of passing skills on to family members because the cutting industry began as a true "cottage industry." Families (not just in I/O but in many surrounding villages) developed specialized skills and that tradition continues even today. Names like Wild, Petsch, Grimm, Haag, Weiss and many others are associated with certain gems and styles of cutting. I'm sure many of them employ non-family members as well. Some family members have split off and compete with relatives of the same name.
As for time spent at the museums and the town in general, I wish I'd had several more days available. It's truly a gem-lover's Valhalla. It's also a very lovely place to visit. I recall eating one of the best hamburgers ever at the Burger King on the outskirts of town since our time didn't allow much opportunity to enjoy the local marinated meat and other specialties.
Rick
