Alto Winter Warrior now with plans

[mikeschn]

I worked on the back of the alto ww a bit this evening. I had to make sure the little triangles would fold down, and that the hatch would still seal. that required a slight modification to the walls, the triangle and the hatch. But you can hardly see any difference.

Also, it's to scale now. The door is now 28" wide, not 711.2".

If anyone wants to download it and look at it in sketchup... here it is...

Have fun!

Here's those triangle pieces folded down on the back wall. (Green)

Mike,

One question I had about the WW and now this design, is how do you keep the lifting sidewalls (hatch?) from splaying? Or is the roof to sidewall joint strong enough to keep this from becoming a concern?

I guess you could use a full or partial rear panel if the length of the roof allows enough arc to clear the rear in the closed position.

It is probably in your Sketchup file, but I haven't had time to learn that software.

Keep up the good work,

Tom

Splaying has never been a problem with the Lady Bug WW which is similar (except the alto WW hatch is longer) - so I'm assuming that using the same construction tech will yield similar results. I'm toying with making the hatch out of foam and fiberglass sandwich to save on lifting weight.

[Ageless]

Why would they splay? They carry no load; function is simply to keep out the weather.

[mikeschn]

True, there is a little bit of splaying on the hatch... that's why I use a knob to draw it in tight...

Thanks to Andrew for his help. He created some drawings of the Alto WW for you guys...

This is turning into one awesome project thread. I will be shopping for my axle and buying steel in the next couple weeks to start this. Thanks you so much Mike and Andrew for you efforts in making this a much easier process. I had a meeting this afternoon with a rep i currently buy epoxy potting resins and polyester casing resins from at work, and even he is excited to help out with this. The jury is still out on whether to go polyester or epoxy over foam. Finally a design both my wife and I like. I will start a build journal as soon as things begin.

Any suggestions for working a shower into the floor plan of the Alto WW?

Here's a top view to help us all think about it...

Looks like a potti/shower combo would fit where you have the portta pot now.

Those pesky wheel wells are in the way. What if you increased the tread and put the wheels outside the body like a cargo trailer or standard tear. More stability, more usable floor space, and little harm to the aerodynamics. You could put the shower/potty against the wall, and probably save a little weight on the chassis. Of course it would change the looks of the unit, but some polished aluminum fenders might add a little zest to the modern design.

Place the shower in the curbside forward corner. Move seatint along streetside wall. Make galley cabinet 'L' shaped aft of door and acrossed bed partition. Access to bed, curbside

As I tend to do, I took a few liberties with your chassis design. See a suggestion below. The gray is 3x2 11 gauge, the red is 3x1 14 gauge, and the blue is 1.5x1.5 14 gauge. The 3x2 has 2.4 times the vertical strength of 2x2 11 gauge with .85 lb/ft penalty. Make up for that with lighter material on the outriggers and some of the cross-members where the strength isn't needed. As shown the steel is 358 lbs. As I said, just a suggestion.........and it requires refinement.

[Carter]

I kind of like Ageless' idea. Better access to the dinette. You could split the galley on both sides of the bed access behind the door and dinette and it would enclose both the wheel wells.

Hey Jim,

I like it...

I modified my chassis to your design, and I get 344#.

BTW, I ran downstairs and measured the axle, and it's designed for a 54" wide frame. I also tweaked the width of the wings to be 78" wide.

I should have sent you the file. Is the body outside the frame or on top? If on top of the steel overall width will end up 80"? if outside 82"? I'm thinking 1" side and 1" overlap of the top.

Going to look at some chairs with Lyd, Back to play in a while.
