Hi
just like you I could not find oil drums so I thought I would make my own .There are two ways of making them, one is to use morrisons vitamin c tubes or if you would like them slightly smaller wilkos denture table tubes .this is my method for vitamin tube you will need ten th plastic card cut into strips of 2mm .you will already have the base of the tube as a lid, if you want to fill the bottom in a piece of 20 th cut to shape and filed round glue to bottom ,the caps are made from 10 th plastic card using a paper hole punch .hope this is useful
the strips of plastic are glued on with super glue after you have rubbed of the printed writing .
