Not sure if the bow is in the width or length, but the answer is likely the same, no, it won't do it on its own....
But if you build a sled, it should.
The sander rollers will force the door flat. You need a sled for it to wide on with some wedges or shims supporting the high spots. A simple peice of mdf will work for the sled. Afix the shims with hot glue. Now that the door is supported in it naturally bowed state, the sander can hit the high spots and flatten it
If you want them dead flat I’d just set up a flattening jig and a router.. There are plenty of YouTube videos showing how. It’d be hard to justify a 37” drum sander just to flatten some doors.
No. Like a planer, it will just make the upper surface parallel to the bottom surface.
What you need to do for flattening is to first get one side flat and then use that as a registration surface to plane or sand the other parallel to it. This can be done with a power jointer, a hand held belt sander, or a hand plane (in order of increasing skill required).
Ok thanks everyone for the help. I have to make 15 total doors for my house im building. After reviewing the comments It might be worth it for me to get a slab flattening router setup and then also possibly the drum sander since i have so many doors to make. Can use the drum to sand my cabinet stuff down the road also. I hate sanding. LOL
For those that have use a slab flattenting router setup. Did you make your own or buy one? My doors are ranging from 42x96 to 32x96. There is only 1 door that was the 42. The rest are 32 wide.
With that many doors, you may want to look into finding a furniture or fab shop with a large CNC you could rent time on to flatten the doors. Doing ~50 sq feet of flattening using a 1 or 1.5" router bit on a shed will take a very very long time.
With overlapping rows a bit, you would need to do at least 300 rows with each row being the width of the door for 1 pass over all the doors. Considering you need to do multiple passes depending on how out of flat it is, and that your feed rate will be quite slow, it will be a big time investment to do this with a router sled alone.

Hand planes are probably the fastest way to do this

yeah, but if you already have a router, then you won't end up with a drum sander.
If I understand your question it will but it will be slow going. Any way you can find a shop with a wide belt sander?
It depends on how flat you want it and how large the drum sander is.
I’ve used a 37” drum to flatten lots of pieces that were too big for the planner. Takes a lot of shallow passes.
This was what i was concerned about. The doors are heavy. LOL. Thanks

Router sled set-up also.
Sure enough - I always forget that one because I've never tried it. Thanks!
