Summary

Using mechanical hand tools is possible where electrical ones are not available.

   If you lack experience in the use of hand tools either  get someone else to do 
     the construction or (even better) work under their guidance!

 

 

Assemble parts and check for leaks

Mark the ‘Filling Level’ clearly on the tube

Measure the ‘Gallery Capacity’ and make written record

Prepare the priming mix

Prime the gallery

Carry out the first refill

 

 


 

 

 

Basic equipment includes:

 

1 – A short length (eg 60-70cm) of high quality semi rigid plastic tubing of the correct dimensions

High quality semi-rigid plastic tube was used for the pilot  Dynamic Fermentation (see ‘Image 1’) though this has now been replaced with colourless ‘Food Grade’ flexible plastic tube for the current generation of  Dynamic Fermenters. The dimensions in either case are: external diameter 17mm  with a 12mm bore and is available in lengths down to one metre (see here for example).

Note: once it has been made, the join between tube and spigot may feel firm,  but be aware that it is NOT leakproof until treated (see the Guide).

 

2 – A medium size glass drinks dispenser (eg 7.5 litre capacity).

Drinks dispensers come in many shapes and sizes; the 7.5L design shown here (picture on the left) was the one used for the pilot project.

Apart from hand tools such as a sharp craft knife you will find the following useful (a search online will reveal a number of suppliers):

  • Washers to fit 15mm spigot (not strictly necessary)
  • Plastic 19mm Bulkhead fitting
  • Beeswax  rubbed directly onto screwthread section of the spigot  (alternatively some layers of  PTFE tape will probably work as well as beeswax)       
  • One or two 1′ (33mm) Cork floor tiles or similar rigid material. Each tile can then be cut up into four smaller squares, shaped and  glued together to make a new lid for the drinks dispenser.
  • Shims for jamming tube in place in bulkhead fitting  (fitted into hole drilled in replacement lid). These can be cut from rigid plastic tube or similar
  • A small improvised stage to raise your ˜Dynamic Fermenter‘ and allow room for a pot to be placed beneath the spigot.

 

The Guide  section that follows this section gives a step by step account of how to fit the items together securely  and in a way that avoids leakage (page 3  onwards); in addition to a well-lit work space and bench it requires patience, a little skill and a few extra tools. It is probably best to allow a couple of days unless you are particularly skilled.
