Worst Airgun Mod I've ever tried 

The Relum Telly had two springs and the one I saw was very powerful. The 'top hat' piston weight makes a difference, as it provides the momentum that the light piston lacks in weight. I made one from bronze for my bsa superstar, shortened the spring and hey presto!

In my opinion the worst was buying a Gamo. Thanks for showing mate!

Good video and thanks to people like you doing these things it helps us all and saves us waisting money on useless ideas .I try to watch all your videos and I always enjoy them keep up the good work and thanks again

Thank you for honesty trace a failure wich could happens to all of us

Just found your video , someone has sold you a pair of Tornado springs an airgun produced by FEG in Hungary designed in the late fifties early sixties went through several mods over the years but the twin spring tec was never really a success. I would suggest using an appropriate Titan xs main spring and replacing the piston seal with a TX 200 seal or contact Ian at Custom air seal Australia I believe he produces a seal to fit that covers the boss on the end of the piston this will improve sealing and reduce noise not sure the piston weight needed unless you decide to go for a shorter and less powerful spring. Remember the heavier the piston the greater the felt recoil. There has been a anti grease movement for the last forty years, but the correct amount of lubricant in the right places can work wonders for recoil and smooth shooting.

The best springs have fewer coils and come in more compressed, they are faster and more effective, I have even seen titanium which makes them much faster. 😮

If you have seen these double spring kits, and thought, I might give that a go. Then don't bother, utter rubbish.

We have all fixed stuff that wasn't broken 😂

Live and learn mate, nice to see you having a go though! 👋

I have a veeery cheap and primitive springer i bought used for 15 euros. In my country you can buy air rifles up to 12J energy without licences. I dont think it was making all the 12J even, what i did to get a bit more power was to dissamble it, ive "hand machined" a spacer to add between the spring and the trigger carrier to give it a tad more compression. I had to modify the the trigger because it didnt latch onto the spring catch due to the more compression. It does have a bit more recoil now, but the power definately increased. The seals are all bad and its really a shit rifle, but its much more accurate now and packs a bit better punch. Best thing, it cost me like 5cent nut that i grounded and drilled to fit the guide.

good jo mate ,nicely explained the idea pal

Great video thank you , also Maybe the piston seal is bad

I think you should put back in not only the front spring guide, but also the rear bush and rear washer.

I think you left out the plastic cylinder that should have been installed between the larger spring and the trigger body. I see that the plastic guide shortened the inner spring and the outer one remained longer. It has happened to me when I put a lot of grease in cilinder, my projectile speed drops, especially with Cometa airguns due to small clearances and tolerances. I personally use MoS2 long term grease and apply it in extremely small quantities and later only a drop of ballistol oil. If you want more power, install either a gas piston or a 3.5mm wire spring. That metal guide that you threw out because it stuck and caused the cylinder to jam. Take it to a master turner and cut off the hat to 2mm. It's a flywheel that gets constant speed without variation, but you'll get a bit more recoil.

Decent high power springers are rare and are usually designed from the get-go. Piston, cylinder sizes etc.

Did you check your piston for a pressure relief hole in the center?

What about the transfer port

One of those kits frome ebay with green syringes I take it? Did you try running it with the factory seals? Because those "high performance seals" are absolute garbage. More recoil with less power often indicates a leak. Maybe also try to turn the inner spring around. Then again it could also be that the internal friction of the spring assembly bottle necks the entire assembly. I got one of those kits a while back and didnt have any luck either.

i Think that at sometime or another we've all been there. Pain but there's a lot of dodgy guys on selling sights, one has just tried to con me luckily eBay have stepped in

Don't change anything as long as it works - and your "original" setup worked EXCELLENTLY, provided that trigger is smooth and predictable. And that amount of power (sub 20 J) is IDEAL for an airgun of that construction and caliber.

drill out your transfer report to 3.6 mm

great vid MDA

You're a cool guy. Thanks.

its that piston top hat the extra weight slams the air out with more pressure giving you more fps.

All is that will achieve is more recoil and abysmal accuracy. don’t forget when you compress the spring, it gets bigger! It’s almost certainly getting entangled with the other one.👍

Never trust a bloke who snores whilst he's awake

Surprised YT didn't ban this video for the activity at 9:26 and 9:42. OBSCENE! lol

After the modification, did you become stronger?

Hello my friend, I'm just beginning my journey, trying to rid my spring air rifles of twang and buzz from the firing cycle. Quite often, I buy things that don't work. Sometimes, I have to go back into the rifle for something and nothing or a minor adjustment. I'd say this is trial and error, and sometimes the gains you see are hard the envisage. Your video was great, just to be amongst fellow like-minded people with a common interest, knowing that not everything they try and do will work out. It's just nice, having a go, and when an idea works, it's great! Thank you.

I have to wonder if you had the ability to turn down the top hat to fit the inside spring and remove a couple of coils off the spring what would have happened. I would measure the inside and outside coil widths and multiply my number of coils, and subtract the top hats length to the shoulder of the head to get the proper amount of coils and not be coil bound. If you follow me, it would be an great experiment. I believe you would get good results

Cuz you left the top hat out, you could of put a couple of washers in to give a bit more compression maybe

Another good video

You bother so we don't have to. And it's much appreciated 🙏

Thanks.

Well that was a waste of your new FAC!! Can you tell me what chrono you are using?

What if you stretch the spring a little. This helped with mu kids nerf guns😂

To much grease will slow the gun down.

Power is nothing without accuracy, what sort of groups are you getting at say 30 yards, ? 😁👍

Do u no I u can mod the new snowpeak defender 50 cal revolver

I think that black bushing should still be in there ,the problem may lay with the installer not the product , the spring being shorter is prabably unloading its energy too early and think about it ! The origanal spring needed that black spacer and its longer , you put in a shorter spring and took out a block that is there to compress the spring , there for resulting in a lower pressure , i think you made the mistake not the product ......

The kit works, there's no reason not to work. Your result is showing that. It is so powerful that it destroyed the seal while dry firing the gun. Never dry fire Dummy!

Looking at what u are trying not a good idea take the right spring an on each turn put large screwdriver in a stretch them you will only a mm on each but will certainly inprove the power

U should remove the spring inside then try again

Never put 2 springs in a air rifle it just get stuck with the big spring it always ends with a disaster .never do it bad idear just tack the small spring out all together your gun will be better in the long 🏃‍♂️ good look 👍 with it do sum research wach a lot of you tube videos be 4 you get a crap ✌ spring kit 👍👍👍👍

u should have upgraded your piston seal that's where your power loss is Dam

Someone that knows what there talking about tell us what guns are easy to rebuild for a lot more power that aren’t that expensive can anyone help ? 🙏

OK👍

OK

So waste of time 🤷‍♂️
