How many shells chairs can you stack on top of each other?  

There's stacking...
And then there's that.

That's my house the night...
That's my house the night Bush got re-elected.

Dang!
I've been phoning, emailing, buddying up to a certain university to get a bunch of old shells that they were about to throw out from a molded building. All the shells in the above picture are now in a huge dumpster because the university said it was a liability to sell fiberglass chairs with a little mold on the surface. I did manage to sneak 30 out though:)
Is it ok to literally dumpster dive under 4 feet of asbestos and mold in order to get another 30?

sometimes...
its best to quit when you're ahead...no point in risking detriment to your health...especially when you have 30x more chairs than you have behinds...share the wealth!!

You've
been messing around in asbestos?
Are you completely insane?

Isn't asbestos a bird? 🙂
My 30 desks were put to the side for me. BUT I did look in the dumpster and saw a ton of asbestos tiles and a sea of colorful fiberglass....even a bunch of contract colors that I've never seen in person. I didn't have my phone or camera on me....would have been a sad sad picture.
I don't know wth to do with 30 desks...besides put them in the corner of my dining room.

.....
i would take a couple, but im sure you probably dont live near me{Phila., PA}.....

Rent a van, put on some good...
Rent a van, put on some good coveralls, gloves, and buy a painting respirator. Then go get the rest of those shells. Come on now, you can't let non-airborne asbestos keep you from rare colored shells!

Orleans,
I do believe that Dumpster Diving in the US is perfectly legal as all refuse has been relegated to the public domain. I would, however, wear a face mask.
LuciferSum is the expert on all questions regarding dumpsters so you may want to wait until he responds. If it were me and I was still in the resale business, I can promise you I would have already cleared out that dumpster wearing a Level IV Haz-Mat suitand a big ol' grin!

Nice score
Are they all wide mount?

Yeah all widemount
All scholastic desks are widemount because they're stackable.

False
Some are narrow mount.

Really?
woodywood, I have to believe you but I've never heard such a thing. I would assume the early desks were narrow mount. After a certain year HM probably produced only wide for stacking them.
