Very impressed with your attention to detail you sure know how to strip down and re assemble an air rifle. Really great job you have done in this video best I’ve ever seen and so detailed. Great job all round and thank you for sharing 👍
Thanks that means a lot, I do like messing around with the lathes and mills, and it is quite good fun working out how to make the different components. Thanks for watching.
Very good video, I've never seen an HW100 completely disassembled and I have to say: I've had two of them for many years now, but *now* I understand so many things that I could only wonder about before! Thanks for that ! But i have some questions, - where did you get the adapter for the big bottle and the big bottle ? - how many PSI (bar) are in the bottle, ml of compressed air and for how many shoots ? - where did you get that nice green shaft ? - do you prefer O-rings made out of NBR (black ones) or PTFE etc (white ones) ? - the barrel has no suppressor, does he ? Must be very loud. - ever thougt about a super short "bullpup" based on your design ? Thanks if you can take your time to answer, greetings from *_germany_*
I said this would be helpful and it was, just sorted a leak and service on my hw100 and couldn't have done it without this video. All i need now is one for the hw110, thanks again
Excellent video. It's good that you film in a way that the guns always visible and its easy to see what your actually doing. I do have a question though. When you cut the spring carrier pin down to 8mm is that from inside the recess or 8mm off the pin thats visible ?
Great video, you're obviously an expert air-gunsmith. I wonder how long HW100's remain airtight out of the box and lying around, I understand they should be left charged, opposite to a springer/relaxed main spring. With a good springer, you know it's always going be ready to go, but with PCP's do they start loosing air after a coupe of years? Perhaps these days, they are made to high enough tolerances/valves, they can keep within 95%-100% airtight over say a decade, however, I have a feeling you probably need to get a HW100 serviced every 3or 4 years to keep it performing as it should.
Hi , just one thing I wasn't sure of is how did you retain the PTFE giudes you fitted to the hammer and adjuster, I think it's an excellent idea to smooth out the action and also kill some of the buzz that you hear on firing.
Great video Dude apart from you need the Adjustable Hammer Spring you dont as once the threadlock is removed from the original hammer spring insert and locking grubscrew it then becomes your.... Adjustable hammer spring for fine tuning.. Also the hammer spring retaining shaft can be removed without cutting the head off it
Good info thanks, the standard one is just a bit more fiddly to do, and I wanted to cut the retaining shaft down so I could fit a PTFE guide over the top, Thanks for watching.
@@sub12airgunners Well informed detailed uploads Dude i really enjoy all your efforts and sharing your knowledge which im sure is most welcome and helpful to all in the airgun world ...Where there are alot who seem to be in the secret squirel club ..Thanks for all your time
Brilliant video, i can see why they cost so much now. One thing though, at about the 22:00 mark, when you fit the pin, PLEASE us a brass punch and not a hammer....
Excellent bit of lathe work on the hammer but trying to find someone to do lathe work for ptfe guide has proved difficult for me to find. what size ptfe tube is used and how much turning down on the rod was done .Think this is excellent way of reducing any spring vibration. once again excellent bit of lathe work.
Was this an older model with the brass bush on the exhaust valve and would it not make it more efficient for a .177 without the bushing? With a bottle fitted it's screaming for a tench reg ,but still looks a beast with the green lam stock you deffo have the best tuning video on RU-vid nice work👍👍
Great work buddy! I have owned my hw100 since new in 2010, it’s is still very accurate and has no leeks whatsoever! My question is, should I leave it alone and wait for issues to arise or should I attempt a full reseal or just wait? I am way More confident now I can just refer to your great video! 👍 thanks
If its working well and with no leaks I would leave it alone, most of the seals the the HW100 are the single use type and should last very well, although if the rifle starts leaking or acting erratic then I would have a look inside. Thanks for watching.
Great video as always ,at 0:52 ,after replacing the o ring that goes after the ball, air stopped from entering the regulator block ! So I had to loosen the valve that holds the ball and small spring! This ,of course , does not work if you want to change between cylinders ! Do you have any theoretical explanation to this problem ? Cheers
There are a couple of different version of the O rings, this one does not use a O ring but rather a rubber seal at the bottom, I put an additional O ring in the bottom and it behaved the way you described, if you are having problems I would recommend HW100 tuning, he would be able to tell you which models need which seal. Thanks for watching.
@@sub12airgunners thanks for your suggestion .I will contact him so soon.In fact , this happened after I replaced that o ring ,everything worked fine before that.
My HW100 developed a leak after about 5 years of excellent service. I followed your video and have replaced the O rings. There is a persistent leak that I finally tracked down to the threaded hole where the action is screwed to the wooden stock. The hole next to where the regulator gauge is attached when setting regulator pressure. Can you kindly suggest how I stop this leak? Thanks.
Please could you explain the difference between the trigger pressure adjustment and the regulator adjustment? If the regulator is at 95 say, then what is the trigger adjustment for? Many thanks
What brand is the "dry lube" you use? Is it made of fine gaphite powder? When I search it online, I only get results for bike chain lube (oil/grease) for dry weather... Great video again!
My 100kt cylinder when removed to fix a leak has developed further into a loose metal sleeve and brass inlet valve, I have refitted the sleeve and removed the valve. Can you please tell if the valve can be serviced and installed or if the Belleville washers and pistons have to be removed first and then reinstalled with the reg pressure setup again. Thanks. Ps I watch all your excellent videos.
You should not have to remove the regulator to service and refit the valve, you should be able to leave the belleville washers in place, and keep you reg setting. Thanks for watching.
As long as it has been filled with dry air and not been abused you are probably fine, they do last very well and don't tend to have any problems as long as they are looked after, although if you are worried you can replace it or get it tested. Thanks for watching.
H100 .177 KT sub 12ft/lb. My above almost 3yr old PCP has dropped power from the original 11.3 ft/lb to 8 ft/lb. it has also doubled the shot count from 56 to 112 . Cylinder pressure does not get any lower even over days of unuse. Can you please advise me what is possibly causing the above issues. I was very happy with accuracy and consistency and it has never before given me any problem. your attention and advice will be greatly appreciated. John.
Hi, its sounds like the hammer spring has fatigued or the reg has crept up a little, you can get a replacement hammer spring kit from HW100 tuning, or even send the rifle to him for him to carry out the work. Thanks for watching.
@@sub12airgunners Thank you so much for your help. I just received two sets of replacement o-rings and a regulator gauge from HW100 Tuning. I will start by checking the regulator setting , I understand that it should be around 90 bars am I correct? Since new the gun has shot around 6000 pellets, maybe as you suggest it should be replaced even so since I might have to heat the sealed AT in order to be able to adjust the hammer. Regarding sending to HW100 Tuning , it might be problematic as I live in Malta Regards, John.
@@johnbonnici8048 Around 90 should be fine, to be honest some are lower and some higher, you could have a little play around if you are so inclined. The hammer spring job isn't too bad to be honest a little patience and it comes nice and easily. Thanks for watching.
