[@mrbig6856]

Crazy Ryan Garcia's father made a reflex bag with the same materials the price is almost $500 thank god for KZbin channels like yours bro saves me money

Just built my cobra bag with the spring and its amazing !! Thank you so much for these videos !

[@Kewlus]

You’re welcome! 😃

[@murphyjeffriesjr4932]

I’m gonna make one. It looks good. Instructions were clear and plus it looks more durable than spending $300 on a cobra reflex bag that will break. I will send pic once i finish it

[@lokami2a807]

God bless you man. Ryan Garcia and all of them are charging 250-500 dollars USD for these and looking at peoples reviews they all have durability concerns with this if it breaks after a few months it’s extremely cheap to replace these parts.

[@Kewlus]

Thank you!!! I think people deserve to have stuff like this at an affordable price - especially if one is willing to put it together oneself. I just posted the instructions with all the links: www.fighterdiy.com/2020/10/how-to-make-boxing-cobra-punching-bag.html

I’m waiting on delivery of what I hope will be the final prototype from the manufacturer. Once I receive it I’ll post an update 👌

[@afrobeat4576]

Thank you 😀

[@afrobeat4576]

@@Kewlus no worries, your videos have been a life saver. I made both arms on the spar bar the same length rather than the left being shorter. Figured it would be more balanced. Constantly doing squats without realizing it now 🤣

[@cutwest2179]

@@Kewlus Actually I did have a question. Will you in the future perhaps sell thicker or wider coil springs? I plan on modifying a speed bag ball as my target and wanted a spring to support the weight of it without it being too slow you know.

[@Kewlus]

I’m designing an inner spring that would work for just such an alternative. You will simply be able to insert the inner spring and the stiffness would increase substantially. Next week I will be testing it.

[@L46K]

Another Amazing Cobra Bag Reedy! Just Finished building the Power Twister one I went with a 40kg Twister and used the foam top of an old everlast bag I had, works great and can take power punches all day long with nothing coming loose. Cannot thankyou enough , saved me alot of money and I even managed to cut some smaller ones down for my younger brother to use. However now I've seen this I guess I gotta get working on another bag. If I place an order for the spring when can I expect my order to arrive in the UK and Also what is the length of the spring so I can start buying parts so it matches my height.

[@Kewlus]

Thank you Liam. The first batch of springs should be ready to ship out from the 26 Oct. Postage to UK it's 9-15 days. It's 9.5 inches long. More details here: www.fighterdiy.com/2020/10/how-to-make-boxing-cobra-punching-bag.html

[@huntingwolf20]

I think the PVC here is quite different thickness. I could barely get my 1" pipe to bend, no matter how hard I hit it. And then trying to go smaller, 3/4" wouldn't fit down inside. I may have to try 1/2" pipe and hope it doesn't break. Would like to get the spring but I'm kind of invested in this thing now with the PVC.

[@Kewlus]

3/4 inch PVC is the best for that I found. It will still break eventually but you might get a couple of months out of it. The spring will fit onto a pipe that has 1.05 inches outer diameter. That’s typically the outer diameter of the 3/4 inch pipe

[@charlesterwilliams1736]

Sir that was one outstanding tutorial and step by step instructional. I am in the United States. How do I purchase the custom spring from you whereby the shipping does not cost me an arm and a leg. I want to purchase the spring. By the way do you recommend this version or the one you make with the fibre glass rod. I am going to make either one of those.

[@Kewlus]

Thank you. You can buy the spring (free postage) here: www.fighterdiy.com/p/kewlus-spring.html

[@yurisavchenko4032]

hi bro i bought 40 kg power bar spring is this feet to 3/4 inch galvanized steel pipe"?and what steel pipe need 2For 3 F thanks ! sent to video with pro 40 KG when I finished

[@afrobeat4576]

Did you have to cut the pool noodle lengthwise to make it fit over the pvc pipe before duct taping it? The hole in the noodle is too small for the 3/4 inch pvc

[@Kewlus]

Try taping the end of the PVC pipe and then forcing it through. It’s a very tight fit but pool noodle hole can expand

[@felixatadjanian3013]

When will the springs be back in stock ?

[@Kewlus]

Mid to late January

[@HenriqueSantos-tl9nb]

Can make this with speed bag on top??

[@Kewlus]

That’s coming soon

[@hunglam928]

You are amazing.

[@Kewlus]

Thank you

[@hunglam928]

Are you planning to have a version with larger spring and perhaps a speed bag attached?

[@Kewlus]

I’m working on an optional inner spring that would allow for a heavier top

[@hunglam928]

Have you considered using a foam barbell squat pad for the top portion? The shape of certain pads may be ideal for targets. Here is a link: www.amazon.com/dp/B08GC8M3ZX/ref=cm_sw_r_sms_api_i_4pJLFb2TBYSBJ. This is just an example. Just thought I’d share.
