First of all, you ought to secure a few corbels. It should not be so hard as it seems, as corbels have been widely spread in house structures for some centuries now. Mainly they have been used for roof supports, but depending of the design, an individual can find them as flooring supports as well.
Consider searching for nice dilapidated homes. I guy houses that would be fine if they weren’t dilapidated. Old style design, mostly. They’ve a whole lot of corbels. Or you may visit some city honest or estate auction, where they sell everything really very affordable. You will certainly find one.
After you have the set of corbels you may want to do a little refurbishing on them. And by that I mean a proper painting and sanding. And an eventual professional cleaning to be able to remove wood parasites, if any.
Next you will need a glass top. That’ll be the true length of your desk , so select your own price. Since the corbels will be connected to the wall and so be the desk’s toes, the glass top will be secure on top of them. Hence the width of the corbel should match the specific width of the glass .
I suggest choosing a thick glass top. Not just it is safer for you but it is also looking better. The corbels are hardy thick pieces of work, so having a thin glass top on them will seem very flimsy and out of proportion.
For securing the corbels to the wall I propose using some corner mounts. You can fix them in four areas each, two in the top and 2 at the base, which will provide a tight and most of all a secure fit. If you are not a fantastic hand with drilling you’d better ask a friend who’s to do it. Next set the glass top and fasten it in position with anything.
There you have it: it is as unique as corbels get and I bet you friends do not own one.
