I remove the plugs by drilling a hole in the centre of the plug using drill bits increasing in size to 3/4 of an inch.
Then carefully cut out the remainder with a die grinder until the it falls out.
The thread is 1 1 /4 x 16 and a tap is available from Tracey Tools.
One of our members manufacture the new plugs in brass that are then sealed using Loc Tite 515.
The small brass plugs are also removed the same way and they are 3/8 Gas.
New plugs available off the shelf.
This might seem to be unnecessary but I am in Australia and the temperature is currently 38 degrees Celcius.
