Re: Oscar rebuild and modification
Thanks KJM,
Ive been trying with a VST 18g and a Gaggia 18g basket (which looks very similar to a Synesso ridgeless).
Just thought Id post an update on the mods. I finally got a pressure gauge courtesy of iaindb (thanks again) which I unblocked from the scale inhibiting it, which I successfully installed and now it works a treat!
I installed it on the fitting with the pressure stat and boiler safety valve. I needed a 1/8 female to 3/8 male to fit to the pressure gauge, then a 1/8 female to male elbow join to get it onto the t-join with houses the pstat and safety valve. Then carefully cut a hole in the plastic body of the Oscar and had to put a little screw through the back of the body into the side of the pressure gauge housing to hold it stable.
Having a working pressure gauge is great! Ive set the pstat to run between 1.05 and 1.2 bar, for the moment it seems to work well but will continue to tinker.
