Rickman fuel tank on the B50

Post by FGF »

Hello ,

I 've bought an old Rickman alloy tank for my B50SS.

I 'd like to shorten it because it's very long 675 mm and the B50SS frame is short !
Cutting line initial project :

almost gap dimensions if cutted straight
almost gap dimensions if cutted straight
To close two boards cutted , i think it could be possible to bend them a little like with these red arrows
and some cutted plates to fill some unexpected holes .

I hope the welder to be optimistic with these choices ...

It is the same deposit as yours.
I made a fiberglass mold and then cut it lengthwise and widthwise. And voila ...

(es el mismo deposito que el suyo.
Yo hice un molde en fibra de vidrio y luego lo recorte a lo ancho y a lo largo. Y voilá...)

Hello Carlos ,
I like very much your '' design '' , especially the aluminium alloy first .

I 'd like to use the swinging arm spindle to put my footrests like many road racers i 've seen .
It' s easier for the footrests but more difficult for the tank ...
The seat is so far from the handlebar on your bike too and i keep the kickstarter .

I meet '' my welder '' next week , i 'm in a hurry to hear his opinion ...

Hello Carlos ,
Would you have yet any photo of the front hole you made , to let the oil pipe go through the alloy tank ?
It could show ideas about the cutting work ...

I will take some photos of you tomorrow, I have respected the original space of the aluminum tank

Many thanks Carlos for the photos,
On the aluminium tank you didn't make any cut to let the oil pipe go through as i understand ...
So you prefer the shorter tank even if it 's a fiberglass one ?

Correct, the oil tube fits perfectly in the reservoir without the need to cut it. I cut the tank width and length to make it shorter and narrower. As you can see, do not touch the front of the tank, it is identical to the original tank.

Sorry Carlos , I 'm not sure to understand exactly your work :

You didn't cut the rear of the aluminium tank to shorten it but
You made a mold with the aluminium tank to have the second one shorter with fiberglass ?
And there is a fuel gauge with the translucent resin and no gelcoat on the fiberglass ...like on the bevelgear 860 Ducati
To shorten the aluminium tank , i think it's easier to work on the front side because it 's a little hidden ...

I 'm very happy to read your way to do it because i 've only fiberglass experience with fairings and seats .
Francois
