I'm getting ready to make a couple for myself, but not 52". Drawer bottoms that wide made out of plywood will have to be carefully constructed or they are sure to sag over time.

Thanks for the tips. I think I'll see if any architecture firms are selling theirs on craigslist.
I got a couple flat file drawers from a local surveying company. The are moving to digital storage and wanted to free up the space. They are pretty well used up though, so I'll probably build new ones on the same design or have a cabinet maker build some.
Chris - that's certainly correct. You'll need to plan for extra net depth between drawers to allow room for stretcher bars to prevent sagging when loaded. Another
problem which you are also probably already aware of is to order the full-extension
slides according to weight specs at full extension, rather than spec only at a common-denominator extension for the series, which is typically only 18". I'd allow a minimum
of 100 lb rating, because lighter than that you get a lot of wobble even if the weight
per se is supported.
I've made my own once they get that big, but not everyone has the right kind of shop. Once a cabinet shop made me a wonderful one in trade for a 20x24 print they
were coveting.
You have to be careful how cabinets are finished. Plywood or mfg composite wood products outgas things like formaldehyde, have wood acids etc. So they need to be
properly sealed and lined before any potential use around photographs. If metal, they need to be finished with inert BAKED enamel for the same reason. Around here,
architectural salvage outfits often sell used flat files, but the condition and cleanliness of them varies widely. One outfit even specializes in them.
Virtually any college has a surplus outlet. I picked up a 28" x 48" flat file with 32 drawers in it for $40.00. Then it cost me that much again to rent a truck to haul it off. But it was worth it.
Architecture and engineering firms are surplussing flat files with the advent of computer drafting. I picked up (2) 50"x 40" 5 drawer sections that were being surplussed and a 40"x30" 5 drawer one from another source. A 52" wide drawer is quite large. Planning firms and Landscape firms tend to work on larger drawings and would also be a good source. Many of these firms went under or downsized during the market collapse and bank frauds of the 2008-9-10 period.
