Learn how to convert your traditional speargun into a roller speargun. I flew to Kauai to meet up with Brian Fern (unkolearnuhow) to convert my Meandros speargun b28 to a MannySub ceramic roller speargun muzzle. Full breakdown here: castandspear.com/roller-spear...
We even did a roller speargun test before taking it out to catch uku on the reef. I must say, this roller speargun conversion kit was easy and effective.

that gun is bad ass.. hell yeah

@castandspear Год назад

Works well!

@SpearFactor Год назад

I love rollers but sometimes a standard gun is just easier to setup

@castandspear Год назад

Totally agree

@highvalleycowboy1 6 месяцев назад

Easier to set up but half the power…

@greenteamadventures Год назад

Nice i have been thinking about doing that to my rob allen 👌🏽

@castandspear Год назад

Are you going to switch out the mech?

@greenteamadventures Год назад

@@castandspear probably not starting with the foam filling and to open muzzle for now

@sussusamogus8860 11 месяцев назад

meandros railguns are the best, i got one myself, their mechanism and trigger are amazing

@castandspear 11 месяцев назад

Yeah they're solid. Thanks for stopping by!

I copied the design of the salvimar tomahawk. The top band has a string inside to limit the stretch. It's connected to 2 bands on the bottom one of which you remove before loading. The inverted roller was disappointing, the pulley cuts your power in half. I've compared many designees in the pool and I like this the best.

@huntergathererspearfishing2603 Год назад

The measure of the 13 inches where the second blue tape was placed to stretch the bands to. How was that calculated?

@castandspear Год назад

I believe that was in the instructions that came with the roller head listing out the amount of pretension.

@Rawly84 Год назад

Hello, i'm wondering to know how to measure the bands, put the correct stretch. i have a meandros b28 too but with 85cm. I'm thinking to buy mvd roller kit. Thanks for the videos. 👍

@castandspear Год назад

Bands are tricky since it depends on rubber material, thickness, internal diameters, pre tension, etc. I’ve heard not so nice things about the mvd roller, just fyi. I was going to go with that one first, but after research decided not to.

@@castandspear thanks man, i´m tented to try to convert, but i don´t know yet which kit i would buy. foaming the barrel reduce significantly the recoil? what bands are you using?? thanks ;)

@castandspear Год назад

@@Rawly84 the foam added a bit of mass, which helps some. It really helped the noise of the metal barrel be muted. I used 16mm small ID mannysub rubber for the bands.

@@castandspear thanks man, Apreciate, good fishing days ;) [[]]

@user-fr1rv3vb1c Год назад

Why did you put foam in the barrel? Wasn't it a normal euro gun you were using, before converting it?

@castandspear 11 месяцев назад

Add some mass plus sound dampening

@sugarfafie Год назад

What’s sort of foam is used there?

@castandspear 10 месяцев назад

2 part marine grade expanding foam. X-30 I believe

@pablodiego8438 Год назад

Is there a method to get rid of the foam in a barrel? I bought a foam filled cuttle fish barrel and id like to get rid of the foam and have it hollow and sealed instead for more buoyancy and less weight .
