how to install floating book shelves + be sure of max load
I want to install some wooden book shelves, with hidden supports, on a natural stone wall.
1) It looks like specialist, concealed pins are available, to insert into the back of the shelves + into the wall, but the manufacturer can only provide the max load rating in kgs/m2. How can I work out the max load per metre run of books?
2) The shelves are to go up on an exposed Cotswold stone wall – i.e. natural stone that’s rough + uneven. Anyone know if this can be done without compromising the strength/integrity of the fixing? Be really helpful to get some tips + advice.
I want to make sure the shelves are totally secure, and do not impose any load on the wall.
