Converting the FGT to CCR

JonnyB · 21st July 2008, 20:48

Hey guys, looking for tips on how to convert my FGT to a CCR. A few ideas i have are. 1. If possible to keep the existing CMF and restrict it to .8L/m 2. If not possible to do 1 then i was thinking about adding a flow restrictor just before the existing CMF, but i am not sure what IP i would get to the KISS valve. 3. Remove the existing piping, connect first stages to the bottles and adding a needle valve from Pelagian. Any ideas. /Jonny

Hi Jonny :-)
As i told you in the phone i think option 3 is the best way to go..
I think it's gonna be neet.
The other two options is gonna be tricky and ''ugly" on the unit
I thaught on this alot wen the unit was in my garage...:-)

see you, hopefully soon Divebuddie

Hey Johan, yeah i know, i am leaning more and more to option nr 3. I do like the manual override though that is below the unit.

My FGGIII was VERY similar to the FGT. It makes a nice rig for
conversion as it's build quality is better than anything available
today.
You'll see a few ideas on the machine that other people have
since picked up and claimed as their own. It was built between
1998 and 2000, and sold to a collector in 2002.
