This unit was made out of just over one sheet of MDF, total material cost £12 plus paint and glue. All the components were rebated into each other with the router (trenched in) so that the 1/2" (12mm) thickness board was then strong enough to carry all the cans and bottles it needed to over its 30" width. To make sure all the groves align I rout the complete sheet first then cut the sides from it, no chance of any errors that way the sides and the back have to match up!
I then glued a complete frame around the front to make it stronger and to make it look a bit more substantial (also stops the tins falling off).
The down side to a project like this is that it ties my little workshop up during the finishing. It has to be sealed, undercoated twice and then glossed - that's over four days, with drying times, where I can't make a dust. Still it looks OK and its a practical unit that I'm sure will be used for many years
