Subject: Pressure Gauge Portafilter Beak On Lever Machine
 

Sorry but im running shots with pressure that inconsistent so i thought maybe i should train with a portafilter with pressure gauge beak.

But first i dont know how to install this, because i never needed this until now (I use Semi-Auto).

Sorry guys for the lieu of my posts

I assume you are using a direct lever machine (laPavoni or Cremina) rather than a spring load (MCAL).

Inexpensive approach -

Wrap enough tape around the handle to provide a "shoulder" (the ring of tape makes the handle diameter larger) of about 3mm and the top of the shoulder is about 10mm in from the end of the handle.

Get a small fisherman's scale that will measure a 15 Kg fish. place the hook at the end of the scale that will hold the fish over the handle so it rests on the "shoulder". Prepare your shot and pull down holding the body of the scale in your hand. Keep the weight of the pull consistent or let it get a little lighter during the last 20% of the pull.

A bit of practice and you should develop a better feel for the pressure of an even pull.

Good luck
