Hi Guys! I recently build a new speargun and i have some questions that i cant wrap my head around. I converted my Pathos Laser Roller 100 into an inverted roller. I changed the bands, the shaft and the trigger mech.
I "dry" fired it and shot a slowmotion video that showed the spear transforming into a spagetti and even turning sideways while still on the pipe of the speargun (alls parts worked as they should have). Sadly i do not have access to a pool.
So long story short: do you think the power will be fine in the water? And would an enclosed track fix this problem for good? Next logical step for me would be thicker shaft --> enclosed track.
Bands:
2x17,5mm small ID Sigalsub 31cm long with 90cm band stretch (no pretention)
2x17,5mm small ID Sigalsub 21cm long with 72cm band stretch (no pretention)
2x 14,5mm small ID Sigalsub 34cm long with 90cm band stretch (1 cm pretention)
(kicker Band 14mm cut to 300% currently not installed)
--> Force should be halfed as i installed 2 Pulleys and the roller head.
Shaft:
7mm Sigalsub HRC (48-50) Shaft 130cm
Trigger:
Ermes Sub Double Roller
P.S. I know that most people like thier spearguns to follow KISS...but i wanted to try something differend with this build.
