Sphincter Protection
The trike I'm planning has no seat... well it does - it's called the floor!
Normally I would ally-panel the floor, but I'm a little concerned that dragging my poop-chute 10cm from the tarmac on an ally-deck might well be
a mistake if I fail to dodge a rock, or am forced to take evasive action onto the verges / kerbs.
But, I'm a realist - it's going to hurt no matter what!
So I guess what I'm asking is - will it hurt lots less if I go for steel? What thickness seems reasonable?

A well placed carbon kevlar panel would help immmensely...

perhaps a GRP seat would assist,...

6mm steel, with a 10mm bolt to ensure correct location 
I'd love to give my imaginary friend a great big hug,
but this jacket makes it impossible.

Now I've stopped giggling
Serious answer coming up
I think whatever metal or thickness you use will conduct inpacts in a bad/uncomfatable way so
Polystyrene...have you got room for about a 1" (25mm) thick piece
1 It's cheepo stuff
2 Comfatable to sit on
3 Warms up to body temp really quickly
4 very good impact absorber (please don't ask as it's a long story involves a suite of polystyrene armour and my children beating the
living hell otta me)

Cheers Rusty... I was indeed going to put a thin-padding down to soothe my butt-cheeks. Hadn't thought of polystyrene!

about 4 or 6 years ago I did a spreadsheet that showed the weight vs strenghts of ali and steel.
As I recall 3mm ali has the same penetration protection as 1.2mm steel, but 1.2mm steel is slightly lighter (or about the same weight).
Depending on how much area you're talking about, how about 1.2mm steel floor with a few mm sacrifical skid plate? When you weld in the floor -
make sure you do it fully around the outside and inside of the chassis tube to stop water from ingressing. (start with outside and stand on the floor
when you do the inside, hopefully then it will permanently be 'bonged' down and not bong each time you stand in it).

why not look into the way they do race seat? basically a plastic bag filled with expanding foam that you sit it til it sets,
Then you have the perfect shape, thin on the ground and it will be the right dimensions to just slot it to the trike

That sounds worthy of a Thread on it's own....

I'm also going to be sitting on the floor, and I'm toying with the idea of making it with two sheets of ally with a piece of marine ply
between.
Maybe 2 mm lower floor, 8 or 10 mm ply and then top sheet of 1.2/1.6 - folded into the seat shape.
Cheers

You can do it quickly. You can do it cheap. You can do it right. – Pick any two.

Nor does anybody else Scootz. I kinda get the feeling you'll be on your own with that one........

Personally I would have put a bit of plywood behind the alloy skin. Very good at absorbing huge impacts. And I would rather be pulling wood splinters
out my my ring than metal. Although, not much to choose between the 2.

Wear some cycling shorts under your trousers or get a thin bean bag and velcro it down.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Probably a twin-spar, but will wait until they see the chassis in the flesh.
