Underseat tank for HP2

[configurationspace]

How do you plan on venting your aux tank, to make sure you can fill it up all the way with fuel instead of having big pockets of air?

Please give the poor guy a break.
he is about to make, a very needed product for the HP2,
and all you do is : how is that done ? you can not do that ! I want to fill from side !. how do you went ?.etc. etc.etc.
It´s only a few in here that just say: thats nice, carry on the good work

For heavens sake, let the man finish the product,
if you like....buy one
if not...dont buy.
I really think we schould salute the guy doing this
not drive him round in the yard, with all kind of questions !

[Harry Sheene]

Looks awsome! You are just about where I was when I quit my project of an underseat tank. I had a perfect foam model that worked with every combination of accessories I could get together...then I spent an afternoon with the rotomolder company. I pretty much hit a brick wall on minimum pricing. I hope yours turns out better! Count me in if it works out to be 500Euro or so!

Cheers-

Relax. The questions posed haven't caused him any major troubles. All the discussion here has been pretty positive and on-topic until you started telling people to keep quiet.

I think we're all hopeful this tank works out and it's been pretty clear from our posts. It's also a project several people have tried and came up across obstacles on so it's only natural that there's plenty of design questions.

congrats, this is a piece of the art, look how it is addapted to seat holes and vanes, look how it deals with shock support form.

each info i see, i feel better about having it soon.

Right, lets be careful fellas. Baby Markus does seem poor and helpless. (I'm joking Markus)


You fekking boob

You want to know how it's made, and you want few prototypes needed during the design and test stage.

I know we have a language difference and thanks in advance for bearing with my curiosity.

By welding, do you mean a process where plastic 'filler material' is added? Or is it a 'fusing' process. Fuse meaning, the two flat mating surfaces are heated to melting temp, and then quickly pushed together. Or a possibly vibration or ultrasonic welding process.

I'm not trying to judge, I am just curious. I wish you much success.

Hello Jim,
today I make my first two prototypes. But they are welded with filler material only for trying Thats because the welding boarder isn´t fine.
Now I have to make a few corrections of my tool. Next week i build a fixing tool for the welding machine and than I can make fusing welding with the corrected form.

you can look on the pictures in our german forum but don´t disturbe at the

Great to see how the tank looks in the frame! 9 litres extra will transform the HP2 as an adventure touring bike.......!
