I have a mild case of the flu, so been tested for covid, and not allowed to leave the house for some days until the test comes back...
Which means I have some time to work on the old rusty HW50s!
I had an extra piston, and has machined it down as much as I dare, plus added a steel seal converter so the piston can take Diana/AA seals.
Had to lengthen the cocking clearance in the piston a few mm's and the stroke is now somewhere between 73-74mm.
Put in a brass tophat from another HW50 project, and a ARH/JM E3200 spring.
The gun behaves quite well during firing, but I have no idea how fast it shoots, as the chrono in in a box somewhere...
