Ok , Im blaming Andy for goading me into this!

All thoughts ,comments,ideas,put downs etc appreciated,cos although I do realise "its my Trike and I can do what I want" I dont want to go down the wrong path,so Im throwing it to the wolves(you lot) to rip apart!

It might be anon starter.If this thread doesnt go anywhere I may get the whole lot deleted,I just dont know!
I dont know how far I will get or if it will work as a trailer ie the 'look' of it behind a trike.,but heres my basic thoughts............so eyes down and look in........
How about a single wheel trailer? They have them for motorcycles. Ive overcome all the tech details in my head for the hitch etc,so its all down to aesthetics. Ive looked at lots of them on the net,and the biggest wheel they use is very roughly 20" diam. the even smaller diam wheel ones look cr*p to me. Some have the wheel enclosed ,some have it stuck on the back which to me looks like an afterthought! So have you now guessed I dont like the ones with small wheels?

Im thinking to use stuff I have here to keep the cost low.............
So what about using the same size wheel as I have on the back of the trike?(Cos Ive got 2 spare!) I also happen to have a car hub(A35) that could be persuaded to fit with a bit of stud repositioning. To show off the wheel Im thinking a single sided round tube swing arm.A round tube draw bar. Im a bit concerned the tyre footprint will be too wide and cause it to" weave" a bit? Poss get round this by putting more air in it?
So what do you think?
