Hi all

Was looking on eBay the other night and found this drop tank which i think i could use for my Lambretta powered streamliner, has any one had a look at one of these? im just a little unsure how suitable it would be for my application, and its always difficult when you are on the other side if the world.

Thanks for your help

IMO it would be fine integrity wise but to cut Kevlar is a nightmare. You'll end up hating the tank.

Maybe its just me but a 24" od sounds awfully small.  You planning on being able to fit yourself inside of there with whatever chassis you plan on making?

Nathan, you are right, it would be really small for you  :evil: but you are used to larger cars.  I know you sat it the lakester when you were a kid, the drivers compartment is 19 x 15... of course it is square, not round.  Yes it will be a tight fit, but a lot of the bike liners are quite small... it will take a lot of planning,

Thanks for your replys, i was worried the kevlar could be a problem, after finding this on eBay i thought it could be a good way of speeding thinks up and save me having to build a body, and having looked at some photos of the old Manning/Rayborn liner i thought it would be possible with my small wheel size.

The Benham tank #34 was a 24" so it can be done.

I have some new aluminum 25's if you're looking for a small tank.
ps, The composite tanks are really thick too so you'd loose a couple of inches once you get inside.

I've taken a look at this tank and think I could us it for a staring base for a mold. The fact that it is close to the dimensions I'm looking for on my build.

I'm just not sure how I'm going to get the thing to my shop, if I was to buy it.

A road trip to Miami would take a while.

Intriguing at least.

I took a long look at the Manning/Rayborn Streamliner in the Indianapolis Racing Museum, and you're right it is small, very small.

As Tauruck said, cutting kevlar is a true pain in the a$$ and also as this was a fuel tank there will be bulk heads and mounting structure inside the tank all that needs to be cut and is also probably kevlar. Using it for a male mold might be a thought but it is not an especially aero shape as it looks like the front and the back are pretty much the same shape, not optimum. Don't waste your time or effort.

Not much matters and the rest doesn't matter at all.

I agree with Rex, it's not worth phuking with. I just had a similar conversation with fastlammy on the whole tank thing. It might look like a short cut from here but it's not the way to go. You really don't want to resign your self to trying to build inside something. It's better to design your bike then design a body to cover it.

Thanks, Just like most racers, I thought I found a little bit of a short cut,  but as usual that doesn't seem to be the case.

One of these days I simply learn, to just go ahead and start from scratch and get done with it.

I sort of like being the one to ask the dumb questions, so...
Does it need a frame? Does "recovered and re-used" mean that they survived non-parachuted landings?
Or is the short answer simply "... rules..."?

Hard to get a 10" tyre with a decent speed rating
Do you have a brand in mind?
