Well done to you - servicing your own or friends' guns makes every range session even more satisfying. Glad that the videos were useful. All the best, Martin

@@MartinHealy oh massively! The tips on removing the inner ptfe seal with an Allan key and the removing the valve stem seal with a pin made my life soo much easier! Are you still shooting Martin???

Hi Fred, Were you a student at Allhallows School? All the best, Martin

Hi Angelo, Even if it is legal to do so where you live I do not recommend trying to increase the muzzle energy of a sub-12 HW100. The HW100 is a beautifully designed air rifle that has stood the test of time and is enjoyed the world over. There are several sections of the design of the HW100 that effectively limit the muzzle energy: 1. The plenum (the chamber in the regulator block in which the firing valve sits) is the reservoir of air at the regulated pressure that is availlable to drive the pellet down the barrel. The size of the plenum cannot be increased so the firing valve would need to be held open long enough, by a heavier hammer, for additional air to flow from the cylinder through the regulator. This would also largely defeat the purpose of the regulator and cause shot to shot inconsistency. 2. As I explained in this series of videos the transfer port is drilled through the block and plugged with a grub screw. In many other air rifle designs the transfer port is a removable drilled brass nipple that is sealed at each end by an o-ring. The brass transfer ports can be replaced by one with a larger diameter hole that allows a greater volume of air to flow through the port to the back of the pellet in the very brief time that the firing valve remains open. The downside of the brass transfer port designs is that the o-rings are yet another point of failure. Weihrauch choose to eliminate this point of failure and I appreciate the simplicity of the HW100 design. 3. If your rifle is a carbine version then the shorter barrel will further hamper your attempt to increase muzzle velocity. Btw the regulator piston and the bellville washer stack are also different on the FAC version. My advice, for what it is worth, is to appreciate the sub-12 HW100 for what it is and just enjoy shooting this classic rifle. All the best, Martin

@@MartinHealy ok Martin thank you very much and thank you for answering me

@@MartinHealy but if I change the piston of the pressure regulator, the hammer and the spring with those of the FAC version, do you think I can reach a power of 24 joules?

@@angeloangelo6405 Hi Angelo, The short answer is 'no'. I haven't carried out the modifications that you are proposing so I can only offer an opinion based on my experience of the HW100 and other airguns. I think that the transfer port issue will limit the max power that your gun can generate. I base this on experience from other guns that feature removable transfer ports and these ports feature larger bores in the FAC/HP versions. To illustrate this point imagine taking a 200mm length of garden hose and a drinking straw. Try blowing as hard as possible down each of these pipes. One other thought occurred to me after your earlier messages. You mentioned that the muzzle energy did not increase despite some large increases in the regulator pressure and I would certainly have expected at least mild increases. I am assuming that you have changed the breech seal o-ring as I illustrated in this series of videos. If the seal is worn then air can escape backwards past the pellet probe when the gun is fired rather than being available to propel the pellet down the barrel. Rather than trying to make your sub-12 HW100 into something it was not intended to be why not sell and buy a replacement FAC model. Stay safe and stay legal. All the best, Martin

Hi Angelo, I have never worked on an FAC gun. However, setting the regulator pressure follows the same tuning rules as sub-12ftlb guns. The ideal tune occurs when the hammer and the regulator pressure are perfectly balanced. If we ignore the hammer spring setting and concentrate on the regulator pressure then: - If the regulator pressure is set lower than the optimum for the hammer force then the muzzle energy will be lower than the maximum achievable. - If the regulator pressure is set too high then the hammer will be unable to fully open the valve and the muzzle energy does not increase, can be erratic, and can actually decrease. After servicing your regulator I would suggest that you apply a 'scientific' approach to tuning the regulator. You will need an accurate chronograph, a carefully selected batch of the gun's preferred pellets and a pellet trap set against a safe background. Setup the gun in a gun rest and take great care to ensure that each time you fire the gun the pellet can be safely collected. Increase the regulator pressure several BAR at a time and for each shot note down the muzzle velocity/energy. Keep winding up the regulator and shooting until you see that the muzzle energy has not increased since the last shot. This will give you the rough regulator pressure needed. Then repeat this process starting say 5 BAR below the pressure obtained in the previous step. This time increase the regulator pressure very gradually say 1BAR at a time to find the point at which the muzzle energy does not increase. You will then have found the optimum regulator pressure for the current hammer setting and this will yield the maximum velocity and the most efficient use of air and maximum shot count. Then carry out range testing to determine if this tune actually yields good groups. If the tune does not give acceptable groups then you may then need to consider a different tune using a hammer adjustment and redo the regulator to suit the new hammer force. Hope this helps. ( My top of the head guess will be a geg pressure of around 115BAR.)

Hi, Feel free to comment here. All the best, Martin

Hi, My HW100 is running at 11.6ftlb. You raise a good point about adjusting the power down - depending on your choice of pellets you may find that you shoot tighter groups at lower velocities. The pressure gauge on the cylinder will only give you an idea about the pressure in the cylinder - you will always need to top up the cylinder before the cylinder pressure drops below the regulator pressure (around 90BAR). I would advise extreme caution when checking the pressure on the cylinders since you are effectively looking down the barrel! Never fire the gun while checking the gauge!! In part 3 of this series of videos I fit an external gauge on to the block to accurately read the regulator pressure. Enjoy your shooting. All the best, Martin

Hi, The pressure gauge thread is standard 6mm and mine has an exposed thread length of 3.75mm and has a dowty seal. I can recommend the gauge supplied by www.hw100tuning.co.uk and they will ship overseas if needed. All the best, Martin

@@MartinHealy thanks bro...

Hi Luke, I confess that I don't know much about the origins of Morris or how it has developed. Some claim the origins go back to the 15th century while others claim that it may even have been part of Druid rituals. One thing is for certain it is continuously evolving. I read that there may now be up to 800 sides in the UK and the variety of styles is huge. I personally love all the styles from the costumes that are predominantly white with flowers and straw hats through to the blacks and dark greens with ivy and deer antlers. All the best, Martin

Thank you for your reply Martin. As I say, it was a complete surprise that we saw it on our last day whilst shopping for pasties and ales, but a good one nevertheless. Very entertaining. So thanks again for uploading to RUclips, as we get to watch again. 👍

You're welcome. Remember that this is an annual event in Lyme.

Hi, Thank you for your kind comments - I hope that this series of videos will be of help when the time comes to service your gun. You may enjoy one of my other RUclips channels in which I review pistols, pellets etc. Here is a link to a budget pellet I tested in the HW100 with surprisingly good results; ruclips.net/video/669_SOr5UX0/видео.htmlsi=oRVtXrx-ZUK70D7P All the best.

Hi Bradly, I don't know how I missed it but I was completely unaware of the tractor run this year. After seeing your comment I Googled 'Colyton Tractor Run' and following the official website the first other listing was for a certain Bradley Champion of Variety! Fame at last! Enjoyed your video - who doesn't look at vintage tractors and get a smile on their face? Apart from when you are stuck behind them for miles on narrow lanes!! Yes, Seaton is changing. Apart from the steel frame building that you mentioned there is also a large development along the Axe Estuary near the harbour. But we can't hold back time. All the best, Martin

I was the only person who videoed the 2024 Colyton Tractor Run, James Widger normally does videos of the tractors but he hasn't posted in years, he is quite a busy person in his life mind you. I'm so pleased you enjoyed my Colyton Tractor Run video I did. Also speaking of Colyton, they have had problems with the water, on Saturday when I went home the road was shut, at the campsite the water was turned off for hours, it is so annoying when it causes so much inconvenience.

Hi Mario, I am glad that the videos have been useful. If you suspect a leak from the firing valve try putting a delayed balloon or thin sandwich bag over the end of the barrel and securing it with a few turns of elastic band. With the cocking lever closed any escaping air will travel through the transfer port and down the barrel. After a day even a tiny leak will start to inflate the balloon. All the best from the UK to Malta, Martin

Hi Ravindra, I only make these videos when I am carrying out repairs or service on my guns. I believe in the motto 'if it ain't broke don't fix it'. However, when the time comes I will continue to make videos. The next video is likely to be the strip down and seal replacement on my Webley Raider 10. In the meantime check out my pistol and pellet reviews on another of my channels - here is a budget pellet range testing session that delivered surprisingly good results - ruclips.net/video/669_SOr5UX0/видео.htmlsi=yTNXGpPg0qptmkBB All the best, Martin

Hi Martin, Thank you for the reply. All the best.

Hi Patrick, Yes, the hogs all display unique characters. Recently there have been a few instances of pushing and shoving between hogs but no-one gets hurt. On one occasion at least I think that the apparent aggression was actually robust sexual advances. All the best, Martin

Hi Loiuse, Lovely to hear from you and thank you for sharing about Sam Edwards. I am not sure if you are aware of the book 'To Buy a Whole Parish' by Nicky Cambell RIP. Page 156 is devoted to Sam and Maud Edwards. Sam was clearly a much loved man in Rousdon and the surrounds. He had a roguish sense of humour. Sam was initially the boatman and later a game keeper (and poacher!) on the Rousdon Estate. I don't know where the Edward's original cottage stood in the undercliff but on the path down to the beach there is a large slumped area which is clearly the result of a landslip and there are some dressed stones indicating that there was a structure there. Unfortunately, the path is currently closed due to a recent landslip. I have made a quick survey of St Pancras church graveyard but could not see a headstone indicating Sam's resting place. All the best from the UK, Martin

@@MartinHealy Thank you for that, I already have the book, my cousin Loraine bought me one back a few years ago. It has my grandparents , the daughter of Sam Ellen maud being married in Australia but they got it wrong, she was married in Seaton in 1909. But it does not matter. Sad that Nicky has gone the book was signed by her. Thank You again.

Yes, the hogs are very lovable. These are wild so we are lucky that they come to visit us. All the best, Martin

@@MartinHealy hopefully you'll post more hedgehog updates!

@@drameydrank3973 Hi, Yes, I intend to keep making updates through this season. I am very much hoping that we will have baby hedgehogs appearing in the garden in the summer months. Here is a link to a playlist of lots of hog videos from last year: ruclips.net/p/PL6pIKMJaFnMdj6G3VpfyfIyxB5kCun-QO All the best, Martin

Hi, I was obviously lucky to be filming at the peak of the blooming. I am afraid that I don't know the species. The Berberis is close to where I live so I can try to find out details. I have a friend who is very knowledgeable but she is away at the moment. If I can find out more I will come back to you. All the best, Martin

@@MartinHealy merci de la réponse ; on trouve peu de vidéos où les pollinisateurs sont si bien filmés.

Hi, Not sure who I am talking to because I just see frogmarched6869. I haven't rejoined the club again this year so far because I haven't been shooting much other than pest control. I hope that the changes at the club are positive. The last times I went I was very impressed with the changes and it appeared that the club was going from strength to strength. I would still enjoy some range time but it takes me 50-60 mins to get to the club. I know it sounds a bit odd but I always preferred weekdays because it is quiet and I can do more concentrated zeroing and ballistics. I still have my beloved HW100 and doubt that I will ever part with it. During the COVID lockdowns I bought a load of CO2 pistols and enjoy 10M plinking with my grandkids. All the best.

@@Incognito1-1 its Martin ,Martin , we used to go up there together when Andy was there , i have rejoined to use it in the weekday afternoons for some fun and setting up the rifles , they have a small group on a wednesday of mainly retired people .

Hi, Glad to hear the vids have been useful. Good luck with the servicing. Yes, in your case it makes good sense to service the inlet valve first and it can be removed without stripping the block. Please be safety conscious and depressurise the gun by removing the cylinder and firing it a few times to completely de-gas. All the best.

Hi Pete, I take your point about the complexity and potential for necessary maintenance. However, the up side is that PCP air rifles are wonderfully consistent and accurate. In fact rifles such as a well setup HW100 perform so accurately that the weak link is the guy or girl on the trigger. All the best, Martin

Thanks Martin for the reply and I do agree with you. But you see so many rifles not very old having problems and some costing over £2000 plus. I had a BSA Meteor when I was 18 costing £25 second hand but alas we all get old and being a pensioner now this sport is well out of my league. Take care happy shooting.

@@petemason57 Hi Pete, There are still some shooting bargains out there. Have you checked out any reviews for the CP1 and CP2 CO2 guns? I have got both of these and they are basic but huge fun. Provided that you accept them as cheap Chinese made guns and are prepared to do a little fettling yourself then they can be a good buy. All the best, Martin

Hi Martin, unfortunately living on an estate with small garden it's not the place for plinking lol. Just spent £3000 las month on new pc, Microwave and central heating boiler so as I said this hobby will be one I can only follow on the internet. I do have pigeon problems here but use a Chinese made Slingshot rifle F (fettled by me) lol. Works well now but with only clay shot. Maybe in next life and by then it will be lasers lol. Take care

Hi, Thanks for your kind comment. Please check my channel for lots more videos of hedgehogs, foxes, owls, badgers etc. All the best, Martin

Hi Roman, Yes hedgehogs are such sweet little characters. Marilyn is a rescued orphan who now lives with us but is free to come and go as she pleases.

Hi, A good place to start your enquiries would be: woodmizer.co.uk/ Then select your country and see if you have dealerships listed in your country. All the best, Martin

Hi Thea, Yes, it is a pleasure to support these beautiful animals. Here in the SW of England the climate is mild so the hogs are still active but now the weather is getting colder they will hibernate. When the wet dog food doesn't get eaten every night I will still leave out dried kitten biscuits in case any stragglers need a top up meal. All the best, Martin

Hi Lee Yu, Hedgehogs are fairly tough creatures. I have filmed hogs and foxes feeding together in the forest. Occasionally the foxes pawed the hog which rolled in to a protective ball. The foxes rapidly lost interest in the hog and returned to the food I had put out for them. So unless your dogs are particularly aggressive they may be able to co-exist. I would suggest that you could try putting out a dish of wet dog food or kitten biscuits. I put an upturned plastic box over the food bowl with a 13cm square hole cut in one end through which the hogs enter. In the UK the temperatures are dropping and the hogs will soon all be in hibernation. All the best, Martin

Hi George, When the cylinder is completely empty there is only the spring pressure behind the firing valve forcing it in to valve seat and it doesn't make a solid seal. If air is just trickled into the cylinder it can leak past the firing valve. When air is rapidly introduced to the cylinder the pressure behind the firing valve rises rapidly and the valve is forced firmly into the valve seat making a seal. However, this is the only time that I would recommend filling rapidly and only until there is say 50BAR in the cylinder. All the best, Martin

Hi Patrick, Yes, the food does look odd filmed under IR light but it is wet dog food topped off with kitten biscuits. The complete food biscuits are good for the hogs teeth. I have made more chicane defences outside the box to make it too difficult for the cats to get in. For the last two nights the cats have been defeated. All the best, Martin

@@Incognito1-1 Ah fair enough, not sweetcorn. The cat is forgiven. Well, not for the theft ofcrs. Good to hear you could sort out the entry path.

Hi Michael, Yes, Nobby is a wild European hedgehog that visits our garden every night to have supper of wet dog food and kitten biscuits. You can see Nobby close up in the video linked below: ruclips.net/video/ZZWdQZC8Z78/видео.html There are lots more videos on my channel of Nobby and a rescue hedgehog named Marilyn who has been living with us for the past 3 weeks so that she can put on weight ready for the winter hibernation. All the best, Martin

Hi again Bradley, Yes this cat Billy has found a reliable food source and has become a bit of a nuisance raiding the food meant for the hogs. He is a really beautiful cat but he doesn't belong to me and I know that his owner doesn't want him to be fed at other houses. I have been increasing the barriers around the feeders to try to stop him getting in and scoffing all the grub. I think that I have recently succeeded but I am still putting the camera out every night to monitor what happens in and around the feeders. All the best to you Bradley.

Hi Bradley, Yes Marilyn is a sweet hog. She lives in the wooden box behind her. Although she is free to roam around the garden she chooses to stay with us so far. Our wild hedgehog Nobby still visits us every night for his supper. All the best, Martin

Aww!!!! very nice, take care. :)

Hi, Glad that you found the videos useful. You raise an important point about wearing safety glasses. I totally agree. Although I did urge everyone to be cautious and not work on the gun while pressurised I should have also urged people to wear safety glasses. I will now add this advice in the video description. By the way, I do practice what I preach and I always insist that my grandchildren wear safety glasses whenever we are shooting even if the chances of a ricochet are very low. All the best, Martin

Hi, I am sorry that I can't offer a DVD - it has been around 15 years since I produced DVDs and I no longer have DVD authoring software. However, your idea of downloading the HW100 files and storing on a USB stick is a good alternative. If you inserted the USB stick into your father's Smart TV he could could watch them on demand as often as he liked. Since your father is into guns he may enjoy one of my other RUclips channels that has lots of CO2 pistol reviews and pellet testing etc. See link below to a playlist to help you find the channel.. ruclips.net/video/PGKyDTvXN3U/видео.html Apologies again for being unable to help in this instance.

Hi Bradley, The same little hedgehog came back last night so I got another minute of film. Hogs really are lovely characters. I will post another video soon. All the best, Martin

Hi Emma, The box is on the path next to the garage and close to the kitchen window. Lovely to have proof that the hogs are visiting us. Tonight they are dining on wet puppy food plus dry kitten and dog biscuits...

Hi Sean, Glad that you found these HW100 videos helpful (this is the 3rd part in a series of videos). Good luck with your rebuild. I would highly recommend that you get the reg pressure gauge because it is such a helpful diagnostic tool apart from being essential for accurately setting the reg pressure. Enjoyed your videos too. One thing that I would recommend is adding a 20 second blank clip (often called a generator) or a photo at the end of your videos. This then allows you to put on an end screen in RUclips without it covering up the end of your video. All the best, Martin

@MartinHealy yes it give me the confidence to attempt it so I ordered the seal kit and the reg pressure guage from hw100 tuning . I am going to attempt it once they arrive Thanks its all new to me am still trying to get my head around the editing ill keep that in mind for the next one. Glad to hear your enjoying them hopefully they will get better as I learn how to edit I'll be referring back to your 3 videos as they explain everything

@@4d.hunting558 Hi Sean, I would recommend fitting the pressure gauge and noting down what reg pressure is and how fast it refills etc before you do the strip down. All the best, Martin
