A customer has a 24×38 chunk of polished black marble that he wants made into a coffee table. After a lot of thought I’ve decided to make the presentation appear to be floating both from a top down view and frontal. I have seen the effect before and have an idea how its done but it will be trial an error unless I can remember where I saw it. Has anyone here seen this effect and if so do you have any pictures ?
Thanks in advance

Steve,
I'm a little unclear about the "floating" effect. Are you thinking along the lines of a series of arches for support or some form of pedastal? How much does this slab of marble weigh?

*Steve,I'm a little confused by what you mean that it is floating from the top view. Do you mean that the base is smaller than the top?Here's a small table I did. Is this what you mean by floating?Scott
*Steve,Here's another more along the lines (I think) of the pedastle thing Dano is talking about. However, this is much larger than the table. This is a church altar 8 feet long.Scott
*Scott, that's close. Dano, the slab is pretty heavy, probably close to 200lbs, maybe more. I'll weigh it before I decide on the wood. The one I remember appeared to have only two legs on the ground but in reality they were an L shape and curved up from left to right (front) and right to left (back). It looked like it was impossible but was actually very sturdy.
*Steve FFW Issue 135 (April 1999, page 66) has a table with a floating top. Might give you some ideas on how to design yours.
*Steve,An arch is very strong, an elipse is even stronger; ever try to "crush" an egg in your hand? Might want to incorporate that in your design for support...just a thought.Dano
*Dano, I like it... Scott I'll check it out.. Thanks all gotta go.. C-ya all tomorrow.S
*ScottM,Holey Gaucamole! Superb pieces, keep 'em comin' so's I can load up my jpeg files.b ;-)Dano
*Dano,Thanks. I have to mention that I was given that piece of wood which became the top of the small table by a friend who found it thrown away behind his shop. It was pitch black and rimmed with two dozen rusty nails. However, he could just make out the grain swirl in there and thought I might be able to use it. I had no clue what the wood was. But I contacted Jon Arno (courtesy of this BBS, way to go Tim, et al) and he helped me to identify it as fiddleback maple. Public tip of the hat to Jon.For all the occasional "frap" which happens here, this is really a great place to share and learn.Scott Murray
*Scott,Those are spectacular pieces. Will have to see if you've loaded them up to the Gallery, if not, please do so.Frap...that's frappe ...and you're right, we've got some talented folks here.Tim
*Thanks Tim.I'll post them over there.Scott Murray
*i Frap...that's frappe ...The cooksters have already overrun your ranks, i see.
*I was going to mention putting a bevel on the underside of the tabletop so it appears to float, then remembered you're working with granite...nevermind!
*Steve --Amazing how these posts help more than one person! We've had a smaller chunk of leftover marble sitting around our house for quite some time, and I've been noodling around how to make an end table that doesn't appear too heavy. The answers you're getting are proving quite helpful.Can I toss out another question without hijacking the thread? What's the best way to attach a marble top to the wooden support frame of the end or coffee table? I believe there was a similar discussion of this a while back, but I couldn't find it. FWIW, I'm interested in the idea of "floating" the top, too, so that may suggest a particular method.David
*I've got the marble now. It's 1- 1/2 thick and at least 250lbs. I think I'm going to have to revise my plans or get it re-sawn. About the only thing that is going to hold this thing up are 4x4's and thats not the graceful elegant look I want. Thanks for all the replys. When its done I'll post it in the gallery.
*David, I've decided that the piece is just too heavy to try to do what I wanted. I'm now going with Cherry Queen Anne legs and a more traditional base. After a lot of thought about attaching it I think that I will expoxy 1x4's to the underside of the top and then screw the base to that. It won't need much because of the weight.S
*Here's a pic of the top.
*Steve, thanks for the idea for attaching the top. Nice piece of marble... mine's smaller, more brown/copper, and has these great chipped, raggedy edges all around. I have a friend who's a potter (ceramicist?) and makes these fantastic pots that look like they were made in the year 2000, buried in the dirt and not dug up until the year 4001. Sort of like future archealogical artifacts.Anyway, I think I'm building the table as a place to display his work!David
