- 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.

Great job on this video!!
meandros railguns are the best, i got one myself, their mechanism and trigger are amazing
Yeah they're solid. Thanks for stopping by!
This is my new speargun of choice: shop.castandspear.com/products/abellan-denton-110
Thanks bro good job
Thanks!
Is there a way to add more bouncy to the muzzle on a roller pipe gun if it’s muzzle heavy?
that gun is bad ass.. hell yeah
Works well!
I love rollers but sometimes a standard gun is just easier to setup
Totally agree
Easier to set up but half the power…
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.
Nice i have been thinking about doing that to my rob allen 👌🏽
Are you going to switch out the mech?
@@castandspear probably not starting with the foam filling and to open muzzle for now
The measure of the 13 inches where the second blue tape was placed to stretch the bands to. How was that calculated?
I believe that was in the instructions that came with the roller head listing out the amount of pretension.
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.
👍
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 ;)
@@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 ;)

Why did you put foam in the barrel? Wasn't it a normal euro gun you were using, before converting it?
Add some mass plus sound dampening
What’s sort of foam is used there?
2 part marine grade expanding foam. X-30 I believe
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 .
depends on the exact material of the foam but pouring in hexane or gasoline might help. Make sure to remove all plastic parts before.
Sorry, I've never removed foam from a barrel.
But the foam doesn’t make the speargun floating to much?
Nope, the tube was hollow before so the dense foam added some mass. It shot better filled
How do you do/tie wishbones for roller with loading wishbone? Been tryint to figure this out
smoke em...
okay.. but you also had to change the bands I guess...
