In this video I take you on my journey making a prototype of the Cobra style of punching bag using a 30kg Power Twister. You can buy a Power Twister on Amazon from around $20-$30 – here’s one: https://amzn.to/30LAlR3.

Your dog is cute as hell
Which twister I should buy tell ?? 20kg or 40
I thought the dog was photoshopped in just floating in dead space for a min lmao
yoo homie thank u for all these
Videos Saved me so much money and also gave me a new hobby . much respect from Massachusetts
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
man just make your own brand and manufacture in china for affordable price i know you can do it
Freaking fantastic. Thank you 😊
Ur crazy lmao i love you 🤣🤣🤣❤❤❤
20 kg spring works?
How many kgs of power twister did you used?
Would you recommend going with the 40kg or the 30kg for the spring? Anybody who has tried it with a 40kg?
This what ive been waiting for. Thanks for the uploas bro.
Will a 20kgs suffice or should I go for 30kgs?
He looks like a Harry Enfield character.
i love this. i already have both!!!
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.
Hey Bob (Reedy) I Purchased A 30kg/66lbs Power Twister From Amazon.. & It Seems Too Stiff Upon My Initial Inspection. Upon Further Watching This Video And Looking A Bit Closer, It Appears You’re Using A Power Twister In The 20kg Range. Can You Let Me Know If I’m Correct Or Are My Eyes Not That Good At Working ?!?? Thanks
Hey Reedy! Is it work with 50kg power twister with speedball on the top? Hugs from Brazil. 🤙🏽
how much kg of resistance for the power twister. thanks bro.
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 🙂
Oh yeah ✨💪🏽👊🏽🥰🤙🏽✨ just a few more refinements. Material upgrades, modification and BAMM!!! A awesome functional design! Going to make one myself!
Nice, very responsive refex bag
Hi guys … How Power twist resistance ? 20 kg 30 kg 40 kg ?????
Thanks!
How lenght the metal pipe below twist power ? Thanks
Greetings sir! How many kg is the power twister?
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
U where bending it like it was a joke.. 30kgs are not that easy are u sure about the twister?
On Amazon I only found the 20 and 40 kg power twister, which would be better?
Can you make not pool noodle but ball?
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
Hey buddy can we try tummy trimmer springs for the next project??
Nice ❤❤
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.
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.
Unique idea awesome
what is the name of that foam you put?
