Funny timing I was literally coming on here to see if @Norvin is still making these tools? If not, does anyone know for sure if these work: https://www.espressoparts.com/products/la-san-marco-lever-piston-tool
It’s pretty expensive for what it is, especially if it’s not for definite that it will fit
Btw Jony I am currently using this Boa: if you can find similar on Amazon etc.
It does a good job undoing the piston, but I would like Norvin’s tool or similar, for putting the piston back on, to make sure it goes on a bit tighter than the Boa does it
