[QUOTE="billirwinnz, post: 145166, member: 1697"] THIS IS NOT AS GOOD AN IDEA AS I FIRST THOUGHT. IF LEFT FOR A WHILE THE TAPS STICK BADLY. I'VE GONE BACK TO CORK BUT STILL USING THE ADJUSTABLE SCREW WHICH ALSO MAKES CORK REPLACEMENT EASIER. [INDENT]Most of the replacement corks I bought were full of flaws so I now make my own using whisky corks or good wine corks.[/INDENT] [INDENT][/INDENT] [INDENT]Drill the cork to 4mm and cut it to length and fit it on the tap tightened until it is held firmly. Linish it down to within a mm or so of the tap barrel with coarse and then switch to fine until you have a smooth round cork just a little bigger than the tap barrel diameter. Grease with vaseline and fit.[/INDENT] Tap the outer pull part to M4 (or 4ba if you are a traditionalist). Cut a countersunk screw to 27mm and put a small screwdriver slot in the threaded end of it. You can also use a normal screw with the head ground down as shown here. USE CORKS AS ABOVE NOT Orings..... (Place 4 size 106 viton orings in place of the cork.) Tap can be adjusted to compensate for wear or tightness by turning the screw. [/QUOTE]
