after shaping ,width 50mm to 66mm ,height 39mm to 26 mm ,i m worried due to low thickness ,the steel sheet in the pictures I used it as a spoke shave but don't know what they call it in english I want to order from ebay but not a available its much better to plan your wood and won't break beside sharpening very simple by files
-
handle always a headache never got same results each time
-
weight 1400 gm ,make experiment for a A mahogany specimen coated with epoxy found out lead ration for ballast is 0.52 ,calculation shown I need extra 50 grams to keep it ballast ,as I use long overhang i put the lead in front of trigger
-
now waiting for coating ,this the most difficult as I had cracked in my previous ASH wood gun ,my worried for the trigger holes how to seal it ! I plan to soak the epoxy coated gun in linseed oil around the trigger area and keep it for couple of days then dry it hope it works ,next build I ll keep larger holes
