Using "Hozelock" type quick release connectors

Not to be used in the bio making process

The brass type hozelock connectors can be useful for various connections outside of making bio and can be used on small bore( ID 14mm) piping BUT you need to replace the O ring with a "Viton" type The O ring is 2mm with a diameter of 12mm,the plastic that clamps the pipe to the fitting is ok with biodiesel but they can be done away with and a jubilee clip used anyway,they also remain airtight upto about 20 PSI (see pics)

Micro HPT

Quick, simple and cheap method for performing the HPT which means you don't have to use the kitchen stove with associated smell in the house!

1 night light, the container from a second and a piece of bent electrical wire. It reaches temperature very quickly, but due to the flimsy nature of the container, cools down when the oil is added. So it needs to be left with the flame burning for a few minutes to reheat.

Drum lid removal

A novel idea from littledave. Slice through a drum seam with a 1mm cutting disk on an angle grinder and you have a removable lid. Dave recommends marking the lid and drum so the lid can be replaced in the same position each time. Not all drums will be perfectly circular and the position of the cut may not be in the same place around the circumference.
