Help ! Main spring

[NickG]

I am in need of a mainspring, with 18mm od the only thing that looks like it might work is one for a Norica Dragon, but I cant find anywhere that has them other than a place in portugal , any Ideas .

[Shed tuner]

let me know when you find something !

This is the hardest part of the puzzle at the moment

I think protec changed their specs, now advertised 19mm

I'm guessing you already know all of this, but just incase

There's an 18mm on here.....says to fit heavy gem rifles??

Thanks for the above , I have a NO11 in at the moment, and its a little close for comfort once compressed , I have a long stroke so the expansion is quite significant , it shoots nicely but the last bit off the cocking stroke is naff, and it wont do anything for the consistency either .

Thanks , basically its a No 11 Titan, but with a smaller outside diameter , so I guess the wire gauge will have to go down , as the spring guide is a little on the thin side already, I will get the measuring stick out

22mm project, Nick?

[NickG]

22mm project, Nick?

21mm already shooting superbly but needs a little refining

[TonyL]

Oooooo, lovely.

Will you be bringing it to the Bash?

[NickG]

most definitely loki wants to test it in its final state.
