Corny Keg Gas Posts on a King Keg Lid

[mancer62]

Please excuse my ignorance and lack of any understanding of anything engineering but id like to ask the following. Is it possible to drill a hole in a King keg Top Tap Lid and connect a Corny Keg Ball Lock Gas Post to enable me to pressurise the Keg using my Co2 tank? If so can I ask the size of hole I would need to drill in the lid to fit it? And would the Ball lock post and short dip tube be all i needed ?

TMM sell a gas post with 1/4" bulkhead so they can be fitted to other receptacles.

Seems to be out of stock at the moment.

I would urge caution - both on whether the receptacle can take the pressure without damage, and ensuring there is a PRV to vent any excess

Edit - GEB have them in stock:

Be careful when using a large gas bottle to pressurise king kegs/plastic barrels as it is too easy to put too much in and they have a low pressure threshold. I know that some have a pressure release valve but they will not release it quick enough if you are too zealous.
So yes is the answer but with care

I use a 13mm drill to fit corny posts to my King Kegs.
I have fitted a secondary regulator to my CO2 cylinder set to 8-10 p.s.i. to avoid over pressure.
