NV122 Fixing my HW98's dark secret. HW98 TBT Short Stroke Kit Installation & Problems. Watch before.
Вставка
- Опубліковано 21 тра 2024
- Well that was a shock. My HW98 decided it identifies as an unregistered firearm so that needed sorting out.
Enter a Tin Bum Tuning Kit with short stroke.
Will it fit, will it work? Will it ruin my favourite airgun? Some of these questions may be answered, probably in the comments before I have a chance to film part 2.
Who else can't wait for part 2?

Short stroke is causing the reduced power.
The addition of the washers to increase preload could make it tougher and harsher to shoot, the opposite of what the kit sets out to offer?
That's my fear with it. The 98 was always docile to shoot, I don't want that to have changed.
But a lot of people rave about these kits, so I'll have to wait and see.
@@nickvending9688 what suits one doesn't another and it's a game of testing and fettling.
It is shocking that a rifle bought over the counter can be over. That is worrying especially if naive enough not to test from time to time
I reckon there's a lot of over power from the factory airguns out there and I'm told ignorance is not an excuse.
I'm keeping everything crossed that the rifle will be what the kit manufacturer claims.
so did exactly the same to my 98 (small tip use a smaller washer or a pound coin for removing the spring works a treat ) fir my gun it was very good indeed power was 10.5 which is bang on what u wanted and it shoots very well indeed no more twang and the shot cycle is much better . recoil is pretty linear and very easy to manage . good good mate be interesting to see how that shoots . however i think he has given you the wrong spring mine was probably only 1to 1/2 coils shorter that the stock spring and i have one power washer
I really should have come in the house to get a coin, problem is I then get grabbed by Mrs V and commandeered to help with X job, cook tea, clear up my mess etc.
Glad to hear yours worked out well, fingers crossed mine follows suit.
It was supposedly the pro kit with export spring, but yes I think it probably wasn't the right one.
Had problems with a hw99 with a tbt maxi kit the springs are supposed to be pre scragged but gave up with the kit in the end and used the original spring with made quides at present got a Welsh Willy kit sitting on shelf to go in . The new springs with the tbt kits don’t seem perform that well and still suffer length loss early on leading to stripping down and adding more washers to get the power back up . If you glue a couple of tap washers together when you remove the back block just push the action down on them and twist do the same with my 95 very easy
Thanks, that explains why the preload reduced so much.
I bought 2 kits, this full pro short stroke kit for the 98 and a standard kit for my 77. I think I'll look at alternative options in future.
I wanted to fit an Arc kit but I knew I'd get carried away with his fancy pistons, my wallet wouldn't survive...
💯 right
I hope you have better luck with your WW kit. The one I got the spring was unfinished on the ends and was very rough ground. The spring was loose on the guide and twanged as bad as the factory gun. I told them about the issues and sent back the spring and guide and they supposedly sent me a new guide, but it was still loose and twanged. A lot of these cheaper kits with the white delrin are just knocked up in a shed by people that don't really know what they're doing. I'd say pay a little more and go for a Vmach, but I don't think they're around any more.
@noire1001 I'd get a Vmach if I bought another kit.
@@nickvending9688 Are they still going then? I have been out of the airgun hobby for a long time and noticed their site no longer works. I got a Vmach kit in my HW97 back when it was called Webley Venom and it shoots amazingly well. No twang and just a very fast and subdued shot cycle. I also bought a second hand Webley Tomahawk about 10 years ago that had a stage 1 Vmach kit fitted and that also shoots great. Comparing the kits side by side with the cheaper versions available really shows where the extra money goes. I do hope I can still get a kit for the HW98 I plan to buy.
I have the TBT short stroke kits Including the springs, in my 97KT and TX220 Mk111. Both run just under 11ft/lb. Both shoot superb.
Thank you, hopefully mine will settle down and shoot well 🤞🏻
I've found that the best spacer to use when removing the back block is either a pound coin or an old 95/98 piston seal. BTW, like yourself, I found my first 98, although shooting oh so so smoothly was rather 'HOT'. I went down the route of short stroking it and It's producing 11.4 fpe and a sweet as can be. I have 2 other 98's, in different states of tune, both sub 12 fpe, and not short stroked, one with a SFS spring & guide with a red Aussie seal, and one with a full V mach glided piston with matching spring and guide. All 3 shoot beautifully, and all 3 feel slightly different but definite 'keepers.' Keep up the great work, and keep the non PC Banter up.
Hello, thank you much appreciated.
That's interesting that yours was over too, I wonder how many more there are.
I think I'm going to glue an old seal to a larger washer, a bit more stability while also protecting the end of the block from scratches.
I did talk with Arc about Vmach kits, hopefully I can get one in future and put the kit from this rifle into my 95.
Do you have a favourite out of your 98s, i.e. a kit you found shoots best?
Many thanks
@@nickvending9688 Hi Nick - the one I use the most, has a SFS spring and Guide with the red Aussie seal - the others are excellent, however that one has the edge on accuracy - the others don't group quite as well at 50m. Its probably the barrel, as it's a very early 98 and I found that the early 95's (barrel weighted version) and 98's have some of the best. I have a particularity good barrel from an early 95, which was used in the build of a reduced cylinder '80 by Steve Pope (RIP) - that combination is exceptionally accurate.
The Glided Piston Kit that ARC are producing - Based on the VMach design and manufacturer - are excellent and I have one in a 95
Thanks for that, much appreciated 👍🏻
The early Weihrauchs do seem to have the edge.
Hola Nick ...definitivamente dejo el traductor ....
Me quedo con las imágenes y el cambio que has hecho ..y como digo .tienes manos de maestro .sabes lo que haces ..
Espero estés bien y en forma .recibe un abrazo.de este amigo .
Hola antonio Espero que te encuentres bien. Creo que probablemente hablé demasiado en este episodio. Quizás también demasiadas insinuaciones, pero no pude resistirme... Espero que sea una mejora para el rifle. Nunca quise alterar este rifle pero lamentablemente la ley me obligó. Gracias por tus amables palabras, cuídate y todo lo mejor.
Nick
I to have experience factory guns going over the limit, and have purchased second hand rifles that when checked were producing well over the limit. I once came across a HW 80 that had been beautifully tuned It shot like silk and I would have bet my bottom dollar it was within the limit when checked the thing was producing 23 ftp, just goes to show you can't trust your ears. Anyway did not want to come across as captain obvious, but could I suggest a different approach, Replace piston seal collapse last coil or two job done. Not that I have anything against Nicks Kits I think they are good value for the money.
It's mad isn't it? I do wonder how many overpowered airguns are out there.
That does sound like a good approach, personally I won't be fitting another short stroke kit.
Too much waffle in the voice over.
You're too kind, thank you.
Sadly the intro was necessary. I prefer to just get on with it, however I had to put that intro in due to some rather odd comments where I was accused of encouraging people to take their airguns over the UK limit...
Hopefully, I've sufficiently done my civic duty so future videos can just feature the necessary info with the usual smattering of smut.
Looking forward to seeing how it shoots now.
Yeah, me too. Need it to stop raining!
@@nickvending9688 Good luck with that Nick, it has rained for pretty much 2 days solid in not so sunny Essex🤣
Same here. Thunder at the weekend apparently. I really need to find a friendly farmer with a 40yard barn.
Looking forward to seeing how she performs!
Thanks Paul, yes it will be interesting. I'm looking forward to it and dreading it all at the same time.
There won't be any improvement in accuracy, more is there any detriment!
After a tin of pellets it will settle down, 😁👍
They always do. I reckon it will creep up to low 11s.
In the USA you can tune your Springer to what ever you choose ! But to be honest I have brought my HW 97 to over 18 foot pounds and every where in between shot like shit 11.5 to 12.5 really is the sweet spot better to hit than miss good video thanks from Gloucester Massachusetts
A lot of people complain about the legal power limit in the UK but as you say certainly in spring guns that power limit is actually at the right spot for performance. Same as you I'd rather hit the target every time than have a super powerful gun that I don't enjoy shooting.
A lot of FT shooters in the UK will say that 10.5 is the sweet spot.
Glad you enjoyed the video, greetings from the West Midlands of the UK.
Tbt kits do one if two things, 1 over power the said riffle e duo butchering the spring to get the power shoot able, 2 power is way down and there more pre load washer that the hoover dam. I ditched all mine and went to another brand which uses standard springs not the silly 29/30 cool springs.,.22 is even worse
Seems I got the second option (I was expecting the first if I'm honest).
Hopefully it will come good. I do worry about the longevity of the plastic parts.
I fit the same kit to my 97k and power was way down 695 to 710,fit the two spacer/slip washers and went up to 750fps with 8.44 jsb pellets.At the end i remove the short stroke,,keep the spacers in place and the rifle was much more consistent keeping the speed about 770fps,that short stroke did not work for me.
I've got a TBT kit lined up for my HW77k, funnily enough it is the standard kit without short stroke. Call it a premonition...
I had to leave out the short stroker in my 98, well under powered. With no short stroker and no washers gave me 10.6 with H+N FTT, perfect for a .177. I spent hours deburring mine before putting it back together as they are really rough with sharp edges, I used a Brit Seal as the original had cuts in it, from HW not me.
BTW, when I first bought it, it was doing 11.95 av, too close for comfort.
FWIW, I accidentally left the 98 cocked with TBT spring for 2 weeks, no difference at all.
I'll see how the rifle goes but yes I may end up removing it.
That's good that the spring held up to 2 weeks cocked. Before i started work on my 98 I tried leaving it cocked for a few days to see if it brought the power back down. If anything it was slightly higher!
@@nickvending9688 Leaving springers cocked doesn't affect the spring unless the spring is made of toffee or something. Your car sits on it's suspension all the time, the coils don't go mushy overnight.
Well the front springs on my MG ZS180 have sagged after 22 years of propping up the V6 boat anchor. My Focus just snaps springs instead 🙄.
I get what you are saying, but springs on cars aren't usually held under full tension (except for when my wife drags me to a garden centre).
@@nickvending9688 OK, fair deuce. If you cock your rifle and leave it for 22 years it might affect it. But a couple of days, even a couple of weeks, won't make a gnat's chuff of a difference.
Seems like a good point.
Scary that a factory bought rifle could be over.....id heard of new rifles dieseling and being over a bit before settling down, but to have it over after this is a concern. I reckon the authorities would still prosecute you.....which is unfortunate if one is on the receiving end 🤔🤔🤔🤔
I'm not alone in experiencing this. Seems Weihrauchs never age, they just get more evil.
Yep, it'd be just my luck to fall foul of the law and there's no way the manufacturer would accept responsibility.
Not a fan of short stroking these imo they don’t need it
For what been spent you could of had the piston glided by a proper tuner with guides to match the original spring 👍🏻
Nice clear video and good to mention about power levels 😊
Yep, I agree with you fully. These kits had a lot of recommendations in the comments on other videos, so I wanted to see what the fuss was all about. As I'm sure you can tell, I can't see what the fuss is all about...
Still, at least it is legal now, albeit extremely legal.
I've been on the tbt website, the way I'm understanding it the maxi pro kit has the full power spring in it ? I may be wrong, maybe the short stroke will eliminate that? Looks forward to the crono test
Hello, thank you for your comment much appreciated.
Yes, the spring is apparently the full power one. The short stroke reduces cylinder swept volume so the power is reduced accordingly, rather dramatically it seems.
The chrono results are mentioned in the video, I had to add all the power washers and still only got under 11ftlb. That may increase as it beds in.
Haven't had a chance to properly shoot the gun yet, it's either windy or raining or I'm working 🙄.
@nickvending9688 hi nick, I'm no expert, but it seems a little counterintuitive to put a short stroke in it and then a full power spring ? Then all the power washers? I'm asking because I have an hw95 on order here in the states I will have to make it 12fpe in the near future thanks peter, I would assume the combination you have would not be the smoothest
@peterconnor4193 the full power spring plus power washers have to go in to bring the power back up.
According to the bumpf and reviews the rifle is supposed to be smoother with the kit. I remain to be convinced.
Would I fit one again? Nope.
@nickvending9688 so that was the kit I was seriously looking at, again I'm no expert so maybe the kit without the short stroke and a 12fpe spring? I would assume this would be a better shot cycle, I really feel your frustration, I recently ordered a 12fpe kit here in the states for a diana 34 unfortunately they sent me a 16fpe kit so I've had to take it apart twice cut coils reassemble ect because they sent the wrong kit , it's still at 14fpe but that's another story, thanks for the video il definitely give that kit combo a miss
If you want a really good kit and don't mind spending a bit have a chat with Arc Tuning.
Otherwise yes, I'd go for a normal kit with a 12ftlb spring. The plastic top hat and guide will make the rifle more refined, at least in terms of reducing the Weihrauch soring noise.
Please what is the name of this thing you use to disassemble the gun? Where does it come from
Hello, the name is:
Irwin Quick-Grip Heavy Duty One-Handed Bar Clamp/Spreader
I bought mine from Screwfix, most DIY stores sell them. Measure the length you need and buy the clamp that's a bit longer.
I only recommend the heavy duty irwin clamps, I've had other brands shatter which really wasn't helpful.
Despite being illegal...I Have never heard of anyone actually being charged with having an "off ticket" air rifle 🤔
It does happen, not often fortunately but I wouldn't mind betting it will become more prevalent.
Less is more bum slide
We'll just leave that one there 😉
Hi nick what chronograph do you use .? My combro went a little bat shit today giving readings all over the place , outside in the shade 😫 more frustration, tia
Mine is a Chrony F1. It needs incandescent lights over the diffusers, LED lights made it constantly error due to the flicker.
@nickvending9688 I thought LEDs were OK it was the florescent that flickerd ? Asking because my cheap chronographs are not reading the same maybe is the leds in my garage 🤔
It seems to be both, I have to use additional lights in my garage (fluorescent) and workshop (LED).
@nickvending9688 I have the same one min it's consistent then it goes to shit , I had h&n ftt 14.66g 5.55mm head size pellets running between 601 fps 11.76 fpe to 614 fps 12.28 fpe ( a little hot I know ) but I the tried jsb 15.89g pellets and it jumped to 13.30 fpe , I've just removed a small slip washer and the ftt are down to around 10.3 fpe I'm beyond frustrated 😠 also I'm using a combro mk4 so I'm also convinced the slight recoil is giving a false reading as it's attached to the barrel idk 🤷♂️
@peterconnor4193 I've noticed sudden jumps with mine but it is then repeated when shooting the rifle and usually due to burning off grease giving sudden hot shots.
I'm not struck on the barrel mounted chronographs, I feel the recoil will falsely increase power but must confess I haven't done a side by side comparison.
Buy a AA spring rifle! It is much more frendly too work with! The accuraty is beond the shooter! Belive mee, it find the target better than mee and probably the most airgunners!
Maybe one day.
Easy to work on for sure but no more accurate than a HW and a fair bit more expensive.
@@davidpaylor5666 Agreed, I have both and my HW97 is just as accurate and much easier to load. Oh yeah, and it doesn't make all that clackety racket.
I'm lucky enough to have 3 hw80s a tx200 a bsa airsporter diana 52 fwb 124 sport and a park rifle rh93 ....always room in my flat for another gun 🤣🤣
You had me at 3 HW80s. Very nice collection 👌🏻
Did it also cure the twang of the spring?
I'm saying yes at the moment.
@@nickvending9688 Good to hear. I guess the Bum Slide must be working then, lol.
That's a genius bit of marketing 😂.
Move to the U.S. and you can have a proper Air Rifle !
Well it's an idea. But if I moved to the USA then I don't think airguns would be top of my list.
@@nickvending9688 check out the AEA Zeus Gen 2 in .72 cal. air rifle.
@nickvending9688 check out the .72 cal. air rifle from AEA.
Zeus Gen 2 in .58 & .72
I get what you are saying and they do look awesome, but if I moved to the US I'd be looking at Garands, M14s, M92s and other great kit that we aren't allowed on the boring side of the pond.
Power washer you need
I think I need a few of them 😂
@@nickvending9688 in it standard spring size , it runs at 9 ft/lbs 9.5 ft,/lbs , add one power washer approx 10.6 ft/lbs so one more washer can take you over the legal limit .

You've got a firearm and just told everyone on the internet. As it is now a firearm. You aren't allowed to work on it. Try practicing what you preach 😮
Actually I believe I demonstrated what every responsible airgun owner should do, which is keep an eye on your airguns lest they stray over the limit and resolve accordingly. If airgun owners can't test and/or fix it themselves then they should take it to someone that can.
My point was that it isn't cool or funny to tune your airguns up over the limit.
But anyway, thank you for watching and thank you for commenting.
@@nickvending9688 Actually what you have demonstrated is your complete and utter lack of respect for the law. You have very clearly admitted that you are the owner of a firearm and shot it. There is no leniency for ignorance. You are lecturing people on the legality of air weapons in the UK while working on a firearm. It's against the law to handle a firearm without a licence. Don't take my word for it, ring firearms and ask them if you feel so confident enough.
Guys a totally fud, what a cringe 😬
I'm trying to work out how that sentence is supposed to make any sense. Bless your heart for trying.
