Simple Fuel tanks using resin, a straw and some clay!
by Ryan Silva

So here is a short how-to On making a Hot Rod fuel tank using a straw (a very large straw!) Some casting resin and some modeling clay.

You will need some mold release - I used Petroleum jelly (aka Vaseline)

I do not know where i got the straw! Il have to ask in my household, I found it in the draw..yes i got lucky :)

The clay is just regular cheap modeling clay, you dont need to use clay..use anything that will clog the bottom of the straw.

The casting resin I use is ordinary fast setting resin.

I started by taking the straw, looking it over, seeing if it is round - this one was pretty round.  So I used the clay, making it pretty flat.  I took some petroleum jelly and a small brush, and brushing the inside of the straw I then stuck the straw down into the clay. This will hold the resin in the straw so there is not leak, and hold the shape of the straw end too.

Now I do not have a shot of the resin pouring, because thats up to you and what brand you choose.

After i mixed up my resin (1:1 volume) I poured it into the straw. This is the result.

I used the end of my file to push the resin through the straw when it was cured.

You will need to do some trimming, thats up to you, and how you do it. I used a hobby saw and small mitre box:

Here is a sanded and complete tank next to a un finished one.  

I used parts from a pocket watch for the fuel cap and neck

Here is the almost finished product, As you can see some pin holes are evident. But thats due to no pressure pot, and a fast cure resin, but its simple, a little body filler will rid that away!
