If you're in the US, go to any hardware store and look for springs made for garage doors. About the same price as a power twister (maybe a little more) and longer so you have some wiggle room.
Double end bags are cheap and probably better kit to use. Cobra bags are good too but ridiculously over priced. Same as aquabags. It's just a bouy with logo painted on it
thank you man!!! i dont have too much money and i was the same idea like you to do the cobra bag, and you do the cobra bag to easy and cheap in one video. nice👌 Saludos desde Mexico🇲🇽
This is pretty funny. I've thought about doing this years ago with those springs you see on garage doors. They come in multiple sizes and are typically 3 to 4 feet. Turns out they're either the same or more expensive than the power twisters lol. Edit: Damn, it turned out sooooo much better than I thought. Great job dude 👍🏽!
This was super helpful man. I've been trying to figure out how to make a cheap cobra reflex bag. My old slow (bottom spring) Everlast reflex bag is old, rusted, beat to death. I'm still using it but it's basically a little bit of metal and 85% tape holding it together.
not really. 50 years ago this how how the majority of people thought. they were creative and built things themselves rather than buying it for much much more money. Reedy is the last of a dying breed
I really like the idea of that kind of feedback and having to move from a punching bag. The pool noodles seem to be about the right kind of size to make sure you're accurate. The different colors could definitely be good for zones of practice. Actually what I want to do is take that same build but bring the spring a little bit lower and use it for my Filipino stick practice. I think you're really onto something and I'd love to see the full build you come up with.
I did do the build for both the toilet paper roll in the past and the volleyball. Both of them turned out all right but didn't seem like they would last because the PVC finally cracked after maybe the 20th time I used it.
Yeah I think opens up a whole lot of possibilities. I’ll need to put some thought into the bottom section height adjustment so that I can test all different kinds of options. I’m also still keen to try it with a ball. Stay tuned brother 🤙🙌
Nice job! I have a cobra timing bag but I got bored and experimented around with various universal and pivot joints that I had lying about to try to mimic the synovial joints of the body. More specifically, I experimented with a parallel angled offset to the cobra neck (the parallel offset is achieved with two pvc angle joints connected by a short length of pvc pipe a universal joint can be attached to this. The net effect is to create a timing bag that mimics the erratic head, arm and kick movements of an opponent. This rotating offset can be placed above or below the spring to produce different effects. It can be flipped upside down. All are useful for training. In my case, I have it set up so that I can swap out straight and offset sections to get different motion from the same basic cobra. You seem like a curious and capable guy. I’m sure that if you gave this idea a try, you could perfect it into something really useful.
What happens when you add the offset with the pivot joint is that the offset and anything that is attached above it can freely rotate in a circle about the vertical axis. So when you punch the bag this swiveling action adds side to side and front to back movement on top of the front to back movement caused by the spring, the overall effect is to simulate the effect of a moving and punching opponent. Try it yourself and you will see.
@@Kewlus great thanks. So for $40 that includes the advertised spring, pvc and 2 foam noodles? What else would I need if I buy this the base? Was interested in putting a very light weight ball on top
I've detailed all the items you need here: www.fighterdiy.com/2020/10/how-to-make-boxing-cobra-punching-bag.html, for both cases: wether you buy the Top Section Kit or just the spring. I'm about to start testing putting a light speedball on top, so that video is to come. I'm also likely to release an inner spring as an option for those people who might have a heavier top.
This looks like the bag for me, my only issue is finding somewhere that sells galvanised steel pipes in the UK tried a few hardware stores but nothing the size I need
I’m subscribing you do great work :) would like item list so I can price up everything and get it ordered. Definitely let you know when I make either the spar bar. Or reflex bar maybe even both if I can afford it :)
What if you took one of the desk top speedballs punchingbag and take the suction cup off and put it on top to look more like the reflex cobra speedballs? I like that you make things at a more reasonable price!!😊👍🏻🖤
What about a regular punching bag speedball, it would still be way cheaper than $299 plus shipping and tax 😁 take care!!!! I like your thinking!!!!!!!!😊
If the spring was higher it would be even faster. I am more interested in the spring itself, like where to get one without buying a spring bar (need it for other projects). Does anyone know what type of spring it is and where can I get one or at least one close to it? And why is it such a mystery spring?
That's actually not the best type of spring for this application. Better spring would be one with space between the coils. Let me know if you find a good source.
Looks great, Im looking to build this one myself. For the power twister what would you recommend could i go even higher than 30/40kg or is 30/40 the best.
Reedy could you critique my build so far? I’ll use the imperial system since that’s how I got them and I don’t have a calculator right now. I have a 3 foot long aluminum tube with 1.5 diameter. Then inside that is the taped up handle of the power twister. Then on the other side there’s a 1 foot aluminum tube with 1.25 diameter. Then I have the speed bag on top. So far it think it’s good but how heavy would the base need to be to keep it in place?

You could simply use a higher rated power twister like 40kg or more. I tested 50kg but that was too much. I’d say 30-40kg is best. Motorcycle spring would likely have too much tension. Anyway I’ve moved from using springs to using fibreglass poles like the fishing of one I made - soo much better! Fast, quiet, low cost.
what bag does ryan garcia and canelo use? Nobody can even answer that! They make cheap bags at the store... Im sure Ryan and Canelo have custom bags build for them that are not distributed! Boxing biggest secret!
The spring they use is different to those that most manufacturers use. I’m currently working with a spring manufacturer to see if I can come up with a similar or better spring
hey mate! just got a 60kg power twister and im worried its gonna be a bit to hard/rigid to work, what do you reckon? I pretend to use steel pipes on both ends of the cobra bag, and on the upper end use a soccer ball with a plunger attached! (i guess the build is heavier than this one, but enough to compensate 60kg?)
You just have to give it a try. I haven’t tried a spring heavier than 30kg, but with a heavier to like a ball I think it should work. You’ll need a super rigid base though. Possibly even bolt to the ground if possible. Good luck 🤙👌
Reedy Kewlus Thanks for the inspiration mate! I will be getting a 25kg umbrella base and if it isnt enough will put a 20kg olympic disk on the top! Keep up the good work brother
notpastrana pastrana It ended up being perfect! I used a steel galvanized pipe, a plunger and a football (soccer) ball and a shitton of tape, so it was heavy enough to have a really good action! Just to consider im holding my base with 4 25kg sand bags (i did my own diy base). Get it bro, My spring is slightly above hip height.

what bag does ryan garcia and canelo use? Nobody can even answer that! They make cheap bags at the store... Im sure Ryan and Canelo have custom bags build for them that are not distributed! Boxing biggest secret!
The spring they use is different to those that most manufacturers use. I’m currently working with a spring manufacturer to see if I can come up with a similar or better spring
@@Kewlus it's very surprising none of these brand names can come up with a decent bag like Canelo uses
@@Kewlus where do you usually find coil springs? I didn't find the 50 kilograms to 60 kg spring that you mentioned
Yes I agree it’s very surprising
hey mate! just got a 60kg power twister and im worried its gonna be a bit to hard/rigid to work, what do you reckon? I pretend to use steel pipes on both ends of the cobra bag, and on the upper end use a soccer ball with a plunger attached! (i guess the build is heavier than this one, but enough to compensate 60kg?)
You just have to give it a try. I haven’t tried a spring heavier than 30kg, but with a heavier to like a ball I think it should work. You’ll need a super rigid base though. Possibly even bolt to the ground if possible. Good luck 🤙👌
Reedy Kewlus Thanks for the inspiration mate! I will be getting a 25kg umbrella base and if it isnt enough will put a 20kg olympic disk on the top! Keep up the good work brother
Thank you 😊
andres escrich how was the 60kg twister..was it too stiff?
notpastrana pastrana It ended up being perfect! I used a steel galvanized pipe, a plunger and a football (soccer) ball and a shitton of tape, so it was heavy enough to have a really good action! Just to consider im holding my base with 4 25kg sand bags (i did my own diy base). Get it bro, My spring is slightly above hip height. If you want a vid of the action and final result dm me @andyescrich
Thank you
