Thread: advice on plywood cabinet

Hi Read the post on joining heavy table top so coming in with a similar problem, i have a job to build a cabinet for a restraunt, it will be 1800 H 900 W and 450 D, i am using 18mm ply as it will be sanded, primed, painted and the external sides will have merbau slats, horizontal,ripped down to8mm to give better appearance, the face edges will also be nosed with a timber edging and there will be overlay cabinet doors and a pair of drawers, side by side for cutlry,with metal sides and runners. i will rout in a back panel 8mm ply it will sit on a 90mmH box style hardwood base and lockable casters for limited mobility. I am making it in a lower and higher section as it will be too heavy to carry up the54 steps from my work shop(pole home) now down to my question, method of construction, i was going to rout the shelves into the sides, say7mm,glue and pocket hole screw them , or screw from outside into edge grain of ply, however i just got a book from the library,"Quick and Easy Custom Cabinets"Anthony Guidice his quick and easy method is, just biscuit join and then screw the shelves from the outside, biscuits spaced to allow for screws between, this would seem to be time saver however can this be a stong as a housed joint for a shelve 900 W?, given that the only heavy items will be on the base shelve which will sit on the base . sorry for the long winded post, but trying to give the best word picture , regards Rossco ,
