Hello Jon, if you dont mind can you make a video of how to make hundle and muzzle similar to whats at end. 15:28

@stickypaddle6432 3 года назад

Your rubbers are probably too long.with the pulleys system the pulleys are limited to 1/2 the travel of the rope you pull too load it so too get maximum omph you would need to measure from the notch of the spear to the back muzzle then 1/2 that for the pulleys travel then divide that by (3 - 1)(for 300%) or (3.5 - 1)(for 350% and so on) 1200mm length from notch to back muzzle would be 1200÷2= 600 600÷(3.5 - 1)=240 240 is the length of one rubber with 350% elongation

Can we see a video how your friend made the muzzle(hole) on the second carbon gun?

@bobbystevens4087 2 года назад

Great video. I have an MVD carbon 120 inverted roller. There is no way to remove the pretension on the 1st band for storage. There is already a hole to the handle that I could open up a little if I needed to. Where can I get A-line anchor or a threaded bead?

@BestMLhighlights6974 Год назад

That's my dream gun I would like to test it.

@loitubiera2634 Год назад

any What kind of epoxy did you guys used for fill the barrel? Is there a particular brand or type ?? Thanks for postying.

@ArnaudDeSmedt 3 года назад

Awesome tutorial video !! Are all the bands 18mm thick or only the black one and the white and green one are thinner ?

@castandspear 3 года назад

DM @mr.californ1a on IG, he's always experimenting with bands. He'll have some ideas on what you're working on that might be better than this specific gun we discussed

Thank you for this video! I am new to this and I am not english native speaker. Is it roller gun the same as rubber speargun or arbalete?

@castandspear 2 года назад

Roller is a different set up than the traditional style

@hatzisgoal 3 года назад

Meandros handle fits correctly with the track of the tube? Higher lower or both the same height?

@castandspear 3 года назад

We'd have to ask Kory. This was a custom handle he made, but I believe it was flush.

Hi, question: how thick is your Gun Barrel from the top of the Rail to the barrel's hole? 2.3mm or 3.7mm?

You never do reel line like this on the reel lol. The knot will be either pulled through or the barrel will break from any decent game fish
