- In this lengthy video, I explain how and why i made my latest roller speargun prototype, and how it only cost 20$ in material!
The first five minutes I explain the gun, and why I chose a larger diameter roller instead of the industry standards. I also give testimony to the viability of cedar has a gun making material.
After i shoot cans and stuff! In a speedo!

Mate if i can make one like yours id be very happy with that, i like it very nice , great work , love the cedar gun , simple and does what you want it to do . Thank you for sharing your video . Thumbs up .
Thanks, may all my subscribers be like you lol
Wow nice! I'm planning to make roller speargun like yours,thank you for sharing bro👍
Really awesome. Thanks for sharing!
Thank you for show and explain sir; 2 T up .
Thanks I will stick to my double bands. Don't really any reason to pay 800 dollars for what I already can do. Really like the video.
well, i made this one for 20$. There is no reason other than trend that makes the rollers so expensive.
I made a similar speargun but I used teak because it’s way easier than coats of epoxy. I have a ton of cedar though, I’ll have to give it a try.
Yeah, I normally go towards iroko but good luck finding dried iroko that will not twist all to hell. Also I use epoxy on all guns because I literally destroy them by diving five days a week, on guns I rarely use, I'll lean towards oil.
@@potvinr do you mostly dive in Baja and Canada?
@@wafflebeaver I dove a lot in Rhode Island before the pandemic. I competed in that region for about 20 years. Last four winters I spent in Baja.
i use "0840UU" rollers (8x40x20.7mm) which you can find everywhere online which comes with a 8mm hole which means you can just use a stainless steel screw/nut to attach it. it does however use ball bearing.
as for improvements to your gun in my opinion the rubber should never be loose it defeats the purpose of a roller gun you are supposed to attach it on the bottom then it always stays there with tension. at the end of the rubber you are supposed to have 2 strings. 1 that gets stuck on the metal distances preventing it to hit the shaft and 1 longer that you can easily grab with your hand while the rubber is under tension to load the speargun (if you search for roller guns you will notice most have 2 threads on the end for this purpose).
It does however come with a hug security concern if done wrong since the thread could throw the spear backwards.
otherwise nice looking gun
It seems that no one understands the two stage loading... the elastic is stretched at 50% umder the gun. Much much much morr than normal rollers.
I have tried four different rollers, one with ball bearings. I find that larger weels work best (simple physics)
The rollers you mention, I searched for them, but all the ones I found appear to have a metal bearing(skateboard type) that would rust out in a second. Were you able to find any of the rollers seen here? I've searched all over for clothes line roller tensioners no luck.
@@DarenFentiman Look for stainless steel (all bearings are however made with high chromium steel) which means that they are corrosion resistant.
Just pour some tap water when you get to land and the salt will wash off.
Just like the spear and flopper.
Do you have a link to the clothes line rollers please , Great video
no lol, they were the cheapest around.
can you please make a video on how to make the trigger mecanisem thanks
I should make one, but i may get in trouble if someone "fails". That said I should make one explaining the workings and the principles that make a mech, what you do with that info would then be on you jajajajaja
link for rollers? thanks
Daren
I'm not selling any guns these day. I don't have the time lol.
@@potvinr Thanks for the share. I run a boat out of San Jose Del cabo, and am always shooting when I can. Did you ever make a version 2 of your cedar roller? What mm bands were you using on it? Thanks Daren
@@potvinr BTW all the links to your old websites lead you to some Chinese porn sites🤐
@@DarenFentiman I made a 120 cm version of the cedar roller with 16 mm bands. It works better with 14 mm. I had some problems with the bottom holding pins, it's back in the shop. It shot great, but I really prefer a traditionnal 2 band speargun.
@@DarenFentiman only one link, the one to miami2 montreal. I will change that lol
