Cone bottoms for tanks
Cone bottomed tanks facilitate accurate splitting of oil and water, oil and glycerol (if you Glycerol wash) or glycerol and biodiesel.
The easiest way to generate the shape or development for a conical bottom is to use the calculator complied by Tony. For security reasons this has to be located outside of the wiki, but it can be accessed via this link or via the forum menu …
Use of the calculator should be self explanatory, but you will need to enter the following information. Tank or drum diameter. Required cone height or required cone angle and the outside diameter of the fitting you intend to use. For these three parameters the calculator will provide all the dimensions to manufacture a cone.
Before making a start with a metal cone it may be advantageous to check everything fits correctly by making a paper or card test cone, it could save you a great deal of time in the long run!
If required a tab can be added to the development to assist in assembly and welding.
