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 👍🏽!

Super awesome idea! Best reflex bag DIY ever by far!

I just repaired an everlast reflex bag that had a busted bladder thanks to your videos!! Keep it up!

aw man! i thought i was the only one that thought of making one using this spring bar.. YOU'RE A GENIUS!

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 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.

Oh snap, I was just about to buy a cobra bag before I saw this video. It even looks more durable than everything on Amazon and way cheaper to build.

So glad I came across this page ! I got one of those springs at home 🙌🙌

Oh yeah ✨💪🏽👊🏽🥰🤙🏽✨ just a few more refinements. Material upgrades, modification and BAMM!!! A awesome functional design! Going to make one myself!

Love this build, best way to upgrade it I can think of is to somehow safely make it so you can safely hit something as small as a tennis ball. Like you said, the smaller the target the more accuracy you need. I got it just drill a hole the size of a pole and some tennis balls and slide them on there in random locations

You live in 2050 man

And yours actually has better swinging action than the Cobra reflex bag in my opinion.

This what ive been waiting for. Thanks for the uploas bro.

yoo homie thank u for all these Videos Saved me so much money and also gave me a new hobby . much respect from Massachusetts

Reedy - Your builds are brilliant and I'd love a full build with instructions. Subbing now!

I was looking for this long time. Thanks

Just done my own one. Awesome!!!!

That's genuis! Thank you!

I didn't finish looking at the video and I liked. And even you didn't get the job done you've earned all praises. Keep up the good work.

Oooh this shall be interesting! Gonna like this video before I watch!

Legend bro! I'm buying all the part tonight!!

Good work Man i will try to do this! Thank you.

Just got my power twister delivered! So excited for the weekend to build this badboy. Thanks man

I love this tutorial this dude smart asf I'm gonna make this

Gosh that works pretty well... Good one 🤙🏼

Loved this

Get that work. I like it!!

I love this mate. Finally someone online that uses metric!! The only thing that would make this video perfect is chowing down on a Bunnings hot dog at the end. No chance of that happening any time soon though. Stay safe out there mate. Love your vids. Keep them coming!

Wow! Thanks man! This helps me a lot!

Thx man brilliant idea, gonna try it out💪

Thank you, bro!

Bro, your own bag look like they work better than most of the ones online. Was just about to buy one too. Fuck that, making my own now. Respect amigo!

Freaking fantastic. Thank you 😊

Excellent work bro

i love this. i already have both!!!

Sweet. That may be the best one

Amazing work here beautiful project I would recommend buying a speed bag and placing it upside down and using zip ties and tape to keep in place

Wow brother,very good,thanks😁💪💪💪👏👏👏

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.

Unique idea awesome

Keep up the good work. your too cool.

Intresting.... nice video! you deserve more subs! bro

NICE JOB

wow good idea thanks broo

You are a BEAST 💪💪💪🔥!!!!!!! Keep them coming!!! From 🇨🇦🇨🇦🇨🇦...Respect!!!:)

Great Work bud!! Keep it going . Hug from Portugal ;)

awesome video do the whole build! i subbed!

Thank you

Awesome 👍

Man, you're legit. I've been wanting to get all this equipment but it's so damn expensive. I bought the Power Twister, but is there a breakdown of the rest of the pieces and a walkthrough for putting everything together? Thanks for the great content and I can't wait to see what you come up with next!

ha you best thanks for the idea i am going to buy spring thanks thanks thanks

Thanks!

Nice one.

For this beauty... I have subbed...

Looks good . U know a try garage apring Wasn’t fast enough, I try one from doors at ACE I welded to make it longer came out good but still looking 4 a Spring to make it faster . Like what ur doing looks good man . Nice work take care my friend

I going to use the springs for the garage door

I made our own base on this but we used spare used tire as base.

Good idea thank you

Nice, very responsive refex bag

I'm truly impressed with your creative idea ! just wonder can that be added with spar bar ? May be difficult as spar bar work with still vertical arm.

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.

You should post a document with all the parts and sizes you used.

I like it now try putting another screen on the very bottom so it can wave around more..

Got the same spring with u but 40kg as u recomended ..it seems pretty tough though and maybie i have to change it or put it to the vase

Nice ❤❤

i currently try to make that in poland

While that's great Will it work with the umbrella base Thank you very much you're very good at what you do

I thought the dog was photoshopped in just floating in dead space for a min lmao

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.

I think it would’ve been better with the spring closer to the top, with the bag attached 12”-18” above the spring. The cheaper versions have the spring low, the expensive versions have the spring higher.

I mad one it so good i love it a lot

The best

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 :)

fuck me dead. this is the best cobra bag ive ever seen no lie lol

Awesome. I am about to get that spring and attempt yo build this. You should sell the man.

Cobra noodle 👌🏽

Hi Ur awesome!!

I want one

Yo reedy please reply if u can, Will the power spring be used for the adjustable one? Because I need to order one and I am looking forward to build the adjustable one

Your dog is cute as hell

Would you recommend going with the 40kg or the 30kg for the spring? Anybody who has tried it with a 40kg?

He looks like a Harry Enfield character.

Full build please

Hey reedy hope you see this. I just wanted to let you know whenever you make the adjustable version of this I am going to make it myself. The reflex bags online are over priced and work just like this. How long until the adjustable version comes out

Hey Reedy! Is it work with 50kg power twister with speedball on the top? Hugs from Brazil. 🤙🏽

Ur crazy lmao i love you 🤣🤣🤣❤❤❤

hey mate reckon the 30kg spring was good or 40kg might be faster, ebay has upto 60kg resistance. oh and cheers for the awesome ideas. def a pocket grab with those models in the market

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 almost watched all your videos. Just want to ask for the size of the GI pipe, is it 1 1/2 or 1 1/4 inch? Thanks

Man you must have conceived and given birth to yourself. So innovative.

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?

Man i own a ringside and a title one..im gknna make this! I already have an old power twister

On Amazon I only found the 20 and 40 kg power twister, which would be better?

Where do you get the steel pipe and flanges from mate

Do you have a video making the other reflex bag with different spring

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!!😊👍🏻🖤

Hey Reedy, I made made my own version of this, following your instructions with a few tweaks. I have mine on an MDF board, and have just ordered some tent pegs to secure it in the ground (on the grass). Im thinking to get a 40kg or 50kg power twister now to make it even faster, do you think that would work? Thanks for inspiring us all

Thank you man! I juste made one myself but I feel it too slow too. How did you finally speed it up ? Thank you !

Hey buddy can we try tummy trimmer springs for the next project??

How lenght the metal pipe below twist power ? Thanks
