0.5mm is roughly 20 thousandths of an inch..That would be a compression ratio of about 17:1.Better get a welding glove to pullstart it if you go that route

At .050" squish youll get about 140-150psi......I run my squish mainly at .030"...Ive run them as tight as .024" and got piston to dome interference and had to modify the pistontop on a mini lathe to true the top up..
