I have my first drysuit and the Halcyon P-valve.
They Halcyon manaul "...recommends using a professional punch (such as a 3/4" grommet punch)..." to make the hole.
That seems like overkill - to buy a grommet machine to make one hole. I've tried to find the right size copper pipe but they only come in 1/2" or 3/4" and ... you guessed it, the sizes are not correct. They say it's like lumber - a 2x4 is not really 2" x 4"...So a 3/4" I.D. pipe is really like 7/8".
Anyway, anyone have another idea on how to punch a hole or where to get the right size item (3/4" I.D.) to make a whole?
I'm not inclined to burn a hole using any type of tool for that purpose. I'm looking for help to find the right size item to punch the hole.
All replies greatly appreciated!
