A Hot Sfs Hw95

[valboskie 39]

lI seen this post on another forum and found it interesting reading.

I have a sfs stage 2 tuned 97kt and I love it.

This is not a dig at sfs I just thought it would make a good post there were links to pictures in tbe post but I have them listed here separately

 

 

 

 

Yesterday I bought a secondhand HW95 .177 complete with Hawk 3-9x40 HD scope, mounts, RWS sling & swivels. It was sporting the older style stock with the 310mm barrel & HW silencer so a 95k then.

It does have the Star barrel breech.I didnt bother to try the rifle in the shop as it was going to end up as a test bed gun & believe it or not, I managed to get it for £75.00 below the asking price, not too shabby a deal & one I'm very happy with.

 

I had two or three shots with it this morning just to feel the firing cycle, the first thing I noticed was how silky smooth it was to cock, a little harder than a standard rifle I thought, but very smooth cocking indeed.

When I executed the shot I felt the trigger was a little light & would be a little unpredictable in the long term, probably just down to adjustment.The firing cycle was quick with more than a little piston bounce, quite a bit of bounce in fact but no hint of the usual TWANGErrm I thought, the rifle must have had some work on it, probably full of grease but cant have had a proper tune because certain things hint at a standard rifle.

No dieseling!So over to the chrono, the Skan Diamond was set up, not my favourite but it would do for now.

I dont weigh individual pellets, I take 10 from the tin at random, weigh them & take an average using that with an average velocity; good enough for what Im doing today especially as I suspect things are a bit hot.

RWS Superdome 820 fps..12.42fpe

RWS Hobby 917fps.13.33fpe

JSB Exact 4.52 835fps.13.26fpe

Air Arms 4.51 830fps....12.91fpe

FA Plus 892fps.13.04fpe

Air Arms Express 872fps13.29fpe

H&N FTT 840fps13.21fpe

Most of the readings were not terribly consistent leading me to think there may be an issue with the piston seal, if it's been apart possibly sized, something I don't believe in doing the way most people do it, or at all if I'm honest.

Ok then its hot so I remove the sling, scope & stock not really taking much notice, put these items on one side, the actions lying on its right hand side on the bench. I pick two pieces of wood so I can rest the action on them whilst I knock the trigger pins out & glimpse theres slight marks around the trigger pin holes.

Okay its been apart, not surprising, I remove the pins turn the action & see THIS..its got an intact Sandwell field Sports anti Tamper sticker over one of the trigger block lugs.

This is an honest post & I dont want it turning into any sort gang rivalry as I have seen in the past. I dont care what people may think, I know what I know, what you see is what there is, or was, nothing more, nothing less.

The images are untouched or edited in anyway & taken as the rifle came apart.

The opinions I have are my own & concluded prior to me removing the stock & I genuinely had no idea it was a SFS rifle, so there you go.HERE ARE THE REST OF THE IMAGES

http://s202.photobucket.com/user/wonkydonky1/library/sfs%20stage%201%20hw95%20tune

The spring guide is a standard HW turned down to fit the custom spring tapering from 12.9mm to 13.5mm o/d, not surprising if it's been turned down on a lathe between two centres,

The top hat is Delrin with one shim washer under in the piston & lose fitting in the spring.

The spring is of excellent quality the ends of the spring are as manufactured, not refinished & radially ground, but okay-ish!

 

The piston does not appear polished; if it has then its very light showing some poor manufacturing on HWs part as there are pits in some areas which I wouldn't try to remove as they are too deep & won't cause any problem.

 

The piston sleeve is a standard HW item, no reason why it shouldnt be.The piston seal appears to have been sized.

The cocking slot along the compression tube has been deburred.

The cocking shoe has been polished to a degree both sides, not highly polished there are light score marks from the abrasives used.

The transfer port is 3.2mm dia.The trigger has very little grease in; I suspect this rifle has had very little use because the gold coating was still on the hardened pins in the blade.

 

There's uneven wear on the breech jaws.Non of the above is intended as criticism in anyway just purely observational & for information only.good shooting & enjoy whatever you you use

 

What do you guys think I found it an eye opener

It just goes to show not all tunes are perfect

i had the exact same mate with a s2 tuned 97 running at 14ftlb trigger was light also alot of grey molly smotherd all over wish i would have taken some pics of it to show there was 3 3mm preload washes in aswell when i rang up it was unna be 50quid to have it turned back down to legal n this not a dig but thought would be free of charge if still had at sticker on never mind

[valboskie 39]

My sfs stage 2 tuned 97kt Was running a little hot but davy on here very kindly

Cut and refinished my spring for me.

I have just kept it shooting at 10.3 fpe I could add a washer or two as there are none in it

At the moment.

I bought a brand new shop fitted vmavhed hw98 and a full lazaglide hw95 with a 98 barrel and Warren Edwards stock.

Out of the 3 the lazaglide is the nicest to shoot then the 97 is a very close second

The vmach 98 is last but not that far behind I got it for Christmas its had around 150 pellets through it

So it could get better when run In properly.

 

I think all tuners do a good job and try to keep customers happy but like the rifle in my original post

That 95 was poorly done .maybe it was an apprentice who did the work or a late Friday afternoon rifle

It just shows even top shops can produce poor work at times.

Cheers

hi

this was bought second hand,Wonky Donky don't mention where he bought it,which is a bit unfair!

the sticker in question looks worn hence it could've been removed and placed back?

 

i do not believe!

IF! SFS tuned a rifle,and it was ready to picked up,and once it bedded in, it was over.that they would charge to lower the power,its just not good practise.

 

regards to increased power mine went high,but Tony did tell me to keep an eye on it

i was able to sort mine out,rather than a round 3hr trip for xx minutes work.i like my springers to run between 10.5/10.7

 

i can understand the OP wanting to take it apart,as we all would want to re-grease & fettle a second hand air rifle

 

and i can understand why the OP a known recognised tuner on the BBS,would do.

My SFS S1 HW98 went over power after running in , I took it back to Tony and he took the power down while I had a coffee in the shop and did not charge for either . The pics dont look like a SFS tune to be honest , as far as I know they use a custom fit spring guide and top hat and dont machine the standard down they also dont use a piston liner , watch the view inside the action as Tony shows how much grease is used inside the IMP on the VHTV revew . This particular could have had the internals swaped over and then sold on as the cocking slot has been debured and the trigger seems to have been tuned but internals seem to be near standard . Have to say I shot a 97 tuned by the origonal OP on the BBS the other week and it was very good as good as my SFS S2 77k . I think all the top tuners do a very good job and dont want to start off a slanging match . But this does not look like Tonys work more like a Frankinrifle IMHO ATB mike

You hear a lot of SFS guns going over the limit when they bed in..

 

I have a funny feeling my SFS 98 will! and when it does (if it isn't already?) I will be stripping it to get the spring out.

 

. im not sending it back there its too far and too much hassle, I will just send my spring to my mate who will shorten it for me if I ask him nicely

 

Even if its not what I expect to see when I strip it- it is still a lovely smooth rifle to shoot,

If it does go over Skot and you dont want to send it back you can just remove a preload washer under the top hat inside the piston thats all Tony did with my 98 and it dropped by 1ftlbs saves messing around with the spring ATB Mike

[risingfriend 1,042]

LOL nowt wrong with a sfs tuned rifle And my anti tamper sticker came off with just routine wipe down with a oily rag. i would doubt very much if that was the work of SFS. Just my opinion and my experience of a sfs rifle. You likes what you likes The way i see it if tony was sending rifles out a 9ftlbs everyone would be pishing and whining about how underpowered they are etc.(after the bedding in process took them to an acceptable power.) If it creeps over send it back or drop the power yourself. ( i appreciate everyone wants to stay the right side of the law trust me i have had two new hw100 creep over and i was shatting it)

 

P.S Happy new year to all the THL.

Never stripped it so far so dont know if theres actually any washers in it. That would make things a lot easier tho

Aaron my hw100 went over once.. hope it doesnt go over again!!

mine went over by 3ftlb mate and rang him and was gunna cost 50quid or drive to him and cost me 30 i took out 3 big preload washers and it went down to 11.5 after another 50 shots was back up at 12.9 so then had to remove a coil off the spring the gun was a 97k with cs500 stock on it he even said that it wasnt over and that my local gun shops chrono was out by 3ftlb

To be fair mate im only talking from my own experience of SFS. if that was the case then its not on if you brought it directly from sfs. just out of interest did you use a couple of different chrono's to guarentee the shops was accurate.

yes mate used a shop chrono the red one f1 or a1 carnt remember then a chrombo then one of the lads a1 after talking on the phone and were all reading the same i havnt got any problems with sfs and the tune is alright just alot seem to be going over thing is if you havnt got a crono and are stopped by police with one of these that creep over if you have fac your gunna lose it if not your gunna get a criminal record or fine n jail think they should set them lower like 10.8 knowing that its going to raise to 11.5 when fully bedded in rather than setting at 11.5 and knowing that its going to go over i had like a 1cm of preload washers in mine why add these its just silly little things like that that could ruin a hunters life and lose them everything they love doing
