All I have to do now is cut a retainer from perspex and mount it on the ali base I have had folded.
Looks good, out of curiosity did you try and see if the chrono read a pellet without routing the slots?
Use the extra on making up a few more and flog to Polish chrono owners as an essential accessory...
