Re: [papercreters] Re: PC inside a bus turned RV?

Yes I know about the RTS's. I had a PD4905, you know the old Greyhound bus that was shorter in front than the rest of the bus, inside had stairs you walk up like 3 steps, and with the large storage compartments below that went straight through the bus on both sides.  All busses flex.  Even "schoolies".  It is due to long wheelbase.  The monocoque frame busses seem to flex less than full frame busses as they are a single unified frame and outer shell pretty much, but they all flex.  You just can't tell with the naked eye as you're driving around but they do flex.  My personal opinion is don't use concrete in the mix.  Find some other binding agent. Something that is designed to flex without fatiguing.  That is why poly foam is so popular. It flexes and bends.  There is newer foam that does not lose it's insulation qualities through the years.  I don't recall the details but I think it's closed cell foam.  I had a buddy in Idaho using that.  He wasn't spraying he was gluing it in thin layers straight to the skin of the bus.

SLO for me too! Hi neighbor! The school buses are made quite a bit differently then the RTS. I do belong to several RTS specific groups and am shooting PC around with one of the groups. Someone in that group who is closer to actually insulating his bus then I am is thinking about PC now too. This is the spray foam that is usually used, this particular page doesnt talk about the qualities, but this is it http://www.energysavers.gov/your_home/insulation_airsealing/index.cfm/mytopic=11590 from what I have been told.   I still gotta figure out a mixer since I dont have a rear end, other then my own :) I just dont think a 5 gallon bucket and a drill would go quick enough.....   If the PC is so strong, why is there so much concern over the bus flexing? I have also read that plain ole elmers white glue would glue PC together...... so I was even dreaming about making cabinets and furniture with this stuff and then covering it with 1/8" paneling to look more conventional.......
