Yes Sir, You must be VERY VERY careful specially for what I did. Placing one Detolf horizontally that is built per Ikea specs is one thing, but what I have done is a little different.
You can use 4 Detolfs side by side standing Vertically and place one Hortizontaly on top for a total of 5 Detolfs.
Or, you can do what I did.
I needed Depth. I bought 2 Detolfs. I built the first detolf without the Front Door, so you will have a 3 side fish tank. I placed that one on top of my Batman display table horizontally. You MUST make sure both wooden End caps are supported fully by whatever is under it. At no point should the Wooden end caps hang over the end of whatever table, or cabinet you are placing it on.
Next you need something to support the weight of the glass wanting to flex in the middle and pop out of the detolf plastic channels. I took a full roll of electrical tape and cut the roll in half. This will give you a springy half circle of rubber. I then took that presses as flat as I could and used a large open ended 1 1/2" wrench and placed the flattened half roll of electrical tape in the end of the wrench and used it to PUSH the electrical tape under the glass in the middle of my detolf glass all the way to the back. I repeated this 2 more times. So in all I have used 1.5 rolls of electrical tape. The electrical tape is rubber and gives you a bounce and flex so the glass is supported in the middle and will no longer flex or pop out of the Detolf plastic channel.
Next you build another Detolf without the Back Saftey glass pannel. So you will have 2 sides and the front door ONLY. Yes this make it very unstable. Be very very careful please. You then lift Very Slowly very carefully in front of the First Detolf that was already pushed to the back of your display. Do the electrical tape support trick for the middle of your glass..
End result is 2 Detolfs Horizontally with 32" of depth. Your Detolf in the front will have a Bread Box style door opening so I left the Detolf door up and place a pole to support the weight while Im adjusting my figures, then remove the pole and close my detolf Bread box.
Lots of work but for 130.00 its the cheapest way to have this much space for an Iron man display. I have not setup my HOA inside of it yet, but will try this weekend. For now here is my setup. Please look carefully and thing about how large Tony's platform is. Tony's platform is in the Front Detolf and the Armor suits are in the Second Back Detolf.
