Running torsion box through planer

Mismarked said:
It appears the consensus is that a drum sander would be the right tool and that a hand plane would also work, but there is no clear consensus about what would happen on the planer, and no one reported having tried it. 
    At the same time, there was no suggestion that light passes would be dangerous or would damage the planer like trying to run an end grain cutting board through it.
    In light of the altruistic nature of the FOG forum (and lack of ready access to a drum sander), I feel compelled to try it and report the results.  If it explodes, at least we will have a little more information for future use and I won't be set back that much.
    Will try this tomorrow and report back, hopefully with a video from both sides.

I hope this works out for you but for your safety I would limit the video to what you can take from the input side and minimize your physical presence on the output side.
 
The immortal words of XX everywhere is, "hold my beer, and watch this".
But it may actually work, and one only knows by trying.
Filling it with expanding foam would help.
 
Leading edge damaged on next pass. Will post video next. Interesting results.

i think the video is too big to post. Will work on it.  Any suggestions to reduce size?
 
So basically the most damage occurred when a planer roller was only engaged on one side.  Which kind if makes sense.

I'd consider that a successful result. The only thing I would have done differently would have been to decrease the feed depth, you can hear it in the sound of the planer...back it off by about half and she'd be good to go. This would be really interesting if you installed a Shelix cutter, you'd have even less tear out as it's taking an even smaller instantaneous amount of bite out of the structure.
 
I think that could also be improved by adding a temporary sacrificial piece to the ends. Couple 2x blocks or the like.

Ya I like that, hot melt some substructure to the end to prevent blow-out. Afterwards remove the substructure.
 
What is the stand that the planer is sitting on, looks cool and wouldnt mind one

Husky folding table from Home Depot, about 15 years old.  Not sure if they still sell it.
 
Not to hijack but the Dewalt stand for the DW735 is very sturdy and not badly priced and there are extension infeed/outfeed tables...if you really want to upgrade its capability a Byrd head is the ticket, also reduces the noise signature nicely!  Back to topic.

You could also run somewhat longer boards lengthwise on either side to protect the ends from being loaded on the leading edge by the feed rollers and to prevent any snipe on the torsion box.

I have the portable DW 735 stand with the extension tables...it's a very solid combo and moves effortlessly across the floor. High recommend.
 
Now that this is all over....some what....just curious, last torsion box I made all the pieces were ripped the same width and when assembles all I did was sand a little glue off here and there, and everything was flush for attaching the top. Did I miss something? Was this to thick and you had to take it down a bit?

That went better than I thought it might, what kind of plywood is that?

Not exactly sure.  Bought it from a local hardwood supplier.  Three plies and stain grade veneer on one side and some lighter colored veneer on the other.

This was my first try at a torsion box.  I ripped all of the pieces the same width and then notched them, but not deep enough notches. A half mm deeper would have allowed everything to sit flat.

Thanks. I will check it out.  The planer is really heavy to carry around.  I was also contemplating making a flip stand with the planer on one side and the rigid spindle sander on the other.
