Support 1000lb Soapstone Overhang?
I'm looking for help here. We currently have a very large overhanging laminate countertop which is supported by two corbels attached to a pony wall. We want to replace it with a 3cm soapstone counter (~40 sqft = 1000lbs.) We don't think our current corbels will support the whole counter sufficiently and are looking for ideas on how to support this without adding legs, if possible. The widest part is overhanging the pony wall by about 38'. The overhang from the end of the corbels is about 13'. There is a large span (~ 44') between the corbels. Does anyone have any ideas how we could do this? We'd really like the soapstone on our upper counter.
Here are some pictures to hopefully give you a better idea of what we have.
Sorry for the size, don't know how to make them smaller.
