I've had a little experience of DIY crossbows from younger years but have retained enough of an interest to stay up to date and in particular with some recent compound developments. Burri a Swiss crossbow maker recently came up with this monster below... which does actually look more suitable for a speargun design... bar the telescopic sights and obvious weight. Those double springs would be very difficult to get the balance right though so I've gone for a single.
I've been messing around with this DIY idea for a while and happened to read a post from Sharkey... a DB member... who mentioned the possible benefits of a Compound Speargun... being the smooth and increasing distribution of power through the projectile rather than the instantaneous 'hit' and recoil of our band guns.
I'd therefore really appreciate any advice/thoughts/perceived negatives etc from any of you experienced gun builders out there... it is clearly a madcap idea presently but I would still like to have a go at building one... if its possible/feasible of course!
Thanks in advance!
