Hiya gang. I've been asked this many times over the last year or so and I've been meaning to do a guide for what seems like ages as I took pics as I was doing it. I've finally gotten around to doing it This essentially takes two Ikea Detolf display cabinets and doubles them in size so you have a longer shelf for a more dynamic display range.....useful if you plan on getting all the Fanstoys Dinobots! So line up the roof panels like so: and what you are wanting to do is remove the inner partition of glass so the shelf space sits together so the red line is where you are wanting to cut, essentially the inner groove of where the inside glass partition would sit, use that pre-existing seam as a cutting line and don't go any further in: When done it'll look like this: Now you need to flip it over and use some strong metal struts/brackets, line up the glass grooves so they run together and then screw the struts in place keeping them secure and stiff together. You could do it on both sides to really reinforce it but I was ok with one: Once you're are done with the roof section do the same cut to the floor section and line it up: Again put the brackets in place to secure and strengthen: Once that is secure and the feet are on comes the building process, start putting the inner skeleton in place in exactly the same way you do to a normal Detolf, that skeleton helps hold up the middle section of the roof and keep it lined up for the doors: Add the doors, magnets etc and you should be left with a gap between the doors that is similar to the edges. Welcome to the extra display room: And it looks even better in multiples! The wooden blocks under were due to the uneven floor in my attic space, I've since screwed them to the wall behind and they are solid and not needed anymore. I've tried to keep it simple and straightforward but being my first guide I'm probably missing something so if there are any questions or any other pics of the finished article required let me know. I have thought about trying a triple mod.....maybe one day I'll have a crack at it. I will finish off that I take no responsibility for any errors, I'd only do this if you are confident in your ability. They aren't super expensive units but you don't want to be turning it into a wasted pile of shit! Take your time and make sure you have all the bits necessary before starting.
