After 20 years of making wooden guns of all known configurations, I decided to delve into knocking something up quickly in carbon.
More of a lego style assembly, than a true build, but fun all the same.
110cm invert roller, with ceramic muzzle rollers I turned up in the lathe, ball bearing blocks on the rubbers, 20mm primary rubber, and primeline 16mm rubber as the secondary. Both at 350% stretch.
Only using the 2 rubbers, as this is only pushing a 7mm spear.
Using a lightweight cuttlefish barrel, and MVD muzzle and handle. Will eventually drop some $$ and go with the double roller Ermes mech, which is a drop in replacement.
I'll fix up the overly long loops on the rubber to shackle connection when it comes time to re-do the rubbers next season.
This has already been tested on Warehou at close to full range when double wrapped, so does appear to have the goods. Hopefully will get to test this out on a thicker bodied fish :)
