Mine IS more like a coffin.  It isn't really a camper.  Just a place to sleep out of the weather.

 I know one guy that left Tampa with a little trailer for his dog, tent, sleeping bag etc.  He headed NE for a couple of states then went to Chicago, across the top of the country to Oregon, down to southern CO, across the southern route and back to Tampa.

Another guy left southern CA and rode to Alaska and back.  I would NEVER do anything like that!  I have considered going to New Orleans to visit a friend and then ride back.  But I'm too much of a chicken!! 

The guy from Tampa was in his 20's, the other guy was 69!

I doubt any of these could be pulled with a bicycle, but there are some pretty neat retro plans here for teardrop campers.  One is even called the Camping Pod!  See it below:
 
I love looking at these but wouldn't trade my R-Pod for any of them.  I like being able to stand up straight too much!  Have fun looking though . . .

So, Terry -- is this what you have in mind?  (Sorry about the "coffin" comment - I was joking, but on reflection I realize it really wasn't too funny.)  These pics are interesting, so now I get the idea of what you are talking about. The guy that drew these pictures said he wasn't actually sure it would work.  You can see his comments on the website below.

P.S. I can hardly pedal a bicycle (at least yours is motorized) much less PULL a camper with one!

This might sound stupid, but I would get the 2x2's with length to spare, bend them as you wish, then cut the excess ends off.  Then there is no question if you get them the exact length to begin with?]]> Fri, 14 Oct 2011 22:26:55 +0000 https://www.rpod-owners.com/forum_posts.asp?TID=2164&PID=20214#20214 Need Math Help : Dang!!

I actually did the trigonometry to find the radius of the circle and the angle subtended by the arc because I figured I'd need it to plug into an arc calculator. Should've googled first. The arc will be 10.72502' in length. (My calculated values for angle and radius plugged in worked out to 10.72513', with a 8.00007' width and a 3.00004' height, FWIW (which is nothing, really...)).

I was planning on using Luan but I couldn't think of the name of it!LOL  On the inside, between the studs I will put that spray foam stuff.  It should be cozy!  It might take a year to make it.  I'm in no hurry.  I was think of making the front axle like what a kid's wagon is.  That way it will follow the bike in turns a lot easier.  Then again it might not have front wheels.  Just a push down set of legs to stabilize it when I'm inside.

Well, I never was very good at cypher'in (unlike Jethro Bodine) but....
 
My neighbors just sold their popup and bought a home made "teardrop" sort of trailer ...but it is square.  A fellow got it about 95% done and then decided not to finish.  Their main interest is in caving (I say "caving" because I don't know how to spell the word "spelunker") but, they camp when caving.
 
Anyway, their camper has 1/4" luan plywood for the roof and walls and they painted it with a water proof epoxy paint - black and yellow with bats all over it (it really looks kind of cool).  Though a bit larger than what you have in mind, maybe the luan/epoxy paint might be worth a thought.  Good luck and keep us posted!

I'm claustrophobic myself and it sounds too much like a coffin to me!  24" wide?  I'm hyperventilating already.

But seriously, Terry - good luck!  I have faith that you and the techies here on the forum will figure it out.  Just out of curiosity, I'll stay posted on your progress.]]> Wed, 12 Oct 2011 17:50:25 +0000 https://www.rpod-owners.com/forum_posts.asp?TID=2164&PID=20142#20142 Need Math Help : Originally posted by David... https://www.rpod-owners.com/forum_posts.asp?TID=2164&PID=20138#20138 Author: TerryM

Sandwiched plywood would be stronger.  If I had a table saw it would be easier also.  But I don't.  I only have a hand saw.  The 2X2's are cheap and more than strong enough.  The top and sides would have 2X2 studs in them.  The whole thing would be covered with very thin paneling with a plywood floor.  Covering the outside, over the paneling would be aluminum or some type of plastic sheet.

Remember this is something to be pulled by a 2hp. motorized bicycle and it would only be for sleeping.  Nothing else.  The inside width is only 24".

It's very simple really.  Draw a flat line the is 8' long.  Go to the center of that line.  Go up 3'.  Now draw a line from both ends up to the 3' mark.  There is the curve.

Steam bending isn't very difficult really.  It takes either 1 hour per inch thickness or 2 hours per 1" thickness.  All I need is a PVC pipe and 2 end caps, steam source and connecting hose.  I have everything except the pipe.

I will be using 4 24" bicycle tires with 12 gauge spokes.  The back end will open up to get in.  It will have 2 air vents and an LED light inside.  Maybe a window.  One option is a mount on the inside wall for a 9mm handgun.

I would skip the math and build a "model" out of a strip of malleable metal like aluminum or copper. Once you've done that you've got the length number and also a helpful "form" to use for creating other parts of the design.

Just a thought   ...

Need more info on shape of the arc, how verticle you intend to be coming off the trailer, and do you want to come all the way back down to the trailer in the rear, or have a lifted boattail shape..

BTW.. steam bending a kiln dried 2x2 *probably* wont work. I will say I have never tried it, but I have done some steam bending, and kiln dried lumber has it's lignin set by the heat of drying, tends to shatter rather than bend, a small bit it will take, the curve you are talking.. doubtful. Maybe a better plan to use either a lamination (you are going to build a jig anyways.. or cut from sheet goods(what I would do).

Most teardrop builds support the roof with rafters running from the sidewalls..

Some good info here: http://www.teardrops.net  even some plans pages in there somewheres..
