- The BSA Scorpion MK 2. air pistol, A practical demonstration of the strip down and service of this classic air pistol. We also look at how the trigger and safety mechanism works along with how to change the piston seals and other key components with part numbers which are available at John Knibbs International Airgun spares. ( Yes there are still parts to keep your old Scorpion going )
Does anyone know of someone in the US who can work on a Scorpion pistol?
I will pin this comment for you David to see if it helps.
@@MrDazP1adv3ntures Any chance you would be willing to work on it?
Thanks I’m in Canada and got the father in laws when he passed and it was seized in rough shape I just got all the parts and a new spring as old one looks like a banana your video is brilliant thank you
Sorry to hear about your loss but I hope the restoration will give you something to remember him by with fond memories.
Thanks for the positive comments too my friend, they are greatly appreciated 👍
Exalent, i was given one a few years ago all in bits, some parts missing and one bit broken, but after watching this umpteen times, I've finally rebuit it and its working, thanks.
That has made my day David. Thank you for letting me know. You've given an old springer a new lease of life....fantastic !
Brilliant 👍,..... Mine’s just seized a couple of weeks ago so I just binned it at the back of the garage because there was no real instruction on UA-cam. Now I can have a go 🤔😃. Thanks from Longridge!!
It will be the buffer washer more than likely.
Longridge , that's a place I cycle to often
MrDazP1 I know, that’s why I mentioned it. 😃
@@snowhat7298 let me know how you get on buddy.
MrDazP1 Will do, thanks. One question, did you mention where to get spare parts or does it have to be a MacGyver job?!
I have a mk1 and a mk2 scorpion pistols , stripped them both down and serviced them fitted a steel piston head as the plastic ones tend to expand with age, new spring, buffer washer, piston o ring and breech seal. The .22 is doing 5.9 ftlbs with a wasp pellet and i`m getting 5.4 ftlbs from the .177 mk2. Had them both re blued by Colin Molloy brilliant pistols i,d say the most powerful available in the uk. A common fault with these pistols is the long sear hammer breaking and this part is no longer available managed to get mine welded, also if you use a thinner buffer washer around 2mm thinner you get around .2 ftlbs more power. Rebuilt loads of these pistols so if anyone is struggling i`d be happy to give any advice or do the re build myself most parts are available
Thanks for sharing your experiences Howard. I really enjoyed the challenge of repairing this one for the first time which is why I love a classic springer.
@@MrDazP1adv3ntures Thanks had one of these in the mid 70's and just had to get another one around 2 years ago. Know these pistols inside out now, your rebuild was spot on wished It was on when I was doing my rebuilds.
@@howardscholes8335 I had a few moments where it was really fiddly to re-assemble but in the end I figured it out Howard. I have an opposed piston pistol to look at next . It has no recoil
@@MrDazP1adv3ntures good luck is it a feinwerkbau
@@howardscholes8335 Hi, it's an original model 6 pal
Another great video Daz , my first air pistol was the scorpion, wish I'd kept it now. If only as the saying goes.
Thanks for the reply Gregory. They are a quirky styled air pistol and and yes if only we knew then what we know now about keeping hold of things........You can still pick em up for a reasonable price but a good one in the box will be 4 times the going rate.
really helpful video but I found the best way to refit spacing washer ,hammer, intermediate sear and spring was to use a shorter dummy pin assemble all on the bench and drop into the trigger housing and drive out the dummy pin with the retaining pin
Yes 👍that sounds like a good method and thanks for sharing.
I just hope the photos help others to get their old BSA'S going again along with contributions for the comments section.
i bought one of these 2nd hand about 35 years ago for £40 quid - brilliant pistol, loads of fun. Wish i still had it but i was only 14 at the time and my mum found it under the bed - she made me take it back :(
That's a fantastic story to share Gary. I was about 21 when I bought my first Gamo High power sniper and even then was worried about what my mum would say.
Great video and its next on my list
Cheers buddy, it was a great
Project to have a go at and very rewarding
Thank you so much.... not only are you a better instructor than my old boys brigade leader...I didn't hear one swear word....or a mention of a blind fold and a stop watch....I will give it a go ... again thank you.... Brian
Cheers Brian , there was a lot of cursing but I never filmed it .......You need good lighting and a pair of glasses to see what's going on.
Don't have a scorpion but do have a hurricane. Worth me watching as some transferrable tips.
I could do to find a Hurricane and see what they are like inside.
@@MrDazP1adv3ntures here is an exploded diagram: www.gunspares.co.uk/images/categories/24528.gif - I got a paper copy when I bought mine in the 1990s. It's a clunky jumpy beast, but that's why I love it.
Just a note ref the spring seating washer. This goes on after the circlip. The inner diameter is larger than that of the piston shaft so it covers the circlip. Sort of help the circlip stay in place and stops the spring touching it.
Thanks for sharing the information 👍
The trigger looks hard work love to know how well it shoots after the service I bought hw45 in 22 and a webley Alecto in 22. And still prefer the scorpion mk2 And even though mines untouched I still think it’s the most powerful. Great video I’ll be referring to to it in the future You should do a video on the blueing. It looks really good. One more old British springer saved from the tip. Well done
Thanks for watching , it shoots much better than before. I guess I could do another 10 shot test with it. I might be getting a weihrauch pistol to service in the near future.
The scorpions are great pistols , the triggers are very complicated but nice and crisp. A good scorpion is around a full ft lb more than a hw45 .
Triggers should be left alone, I still shiver about the time I completely stripped a Feinwerkba 65 pistol to replace the seals and piston ring,it was in pirces on the table for well over a week before I got it back together, and working, again
Great detailed video, thanks. I have the buccaneer rifle which uses the same trigger mechanism but I can’t cock it and might be seized but with this info I can have a more confident look.
Let me know how you get on Dave, I saw a Buccaneer for sale recently around £350.
@@MrDazP1adv3ntures I’ve seen some boxed with original sights, etc. going for that money but I was given this one for £10! Worst case is I can’t fix it and haven’t lost a lot of money but I’m confident I’ll get it working. I’m not interested in selling either way, it’s for my daughter mainly as the bigger rifle has too much kick for her lol
That's the best way to look at it and hopefully the airgun can be brought back to life but it's not broke the bank to get it ..
@@MrDazP1adv3ntures I’ve only just had the chance to get around to sorting the buccaneer rifle… just wanted to say thank you for the video and without it I would have been a bit lost. The rifle had a corroded buffer washer and damaged o-ring. Also once it was apart it definitely benefitted from some light sanding and cleaning with a full re grease.. all working 👍🏼 thanks again
Great stuff Dave, they are a bit fiddly to work on but if you can bring them back to life, it is such a rewarding feeling.
Then you once again for sharing this with me and for others to read too.
Lovely. Great video. Wish you also could do the BSA Magnum.
Thanks Richard, it"s quite a rewarding hobby when you take something apart and works again.
You make a perfect job, congrats. Happy new year for you and your family.
Thank you Jorg, it was a really enjoyable project to work on and all the best to you for 2022.
Great video helped a lot I put everything back together all clean etc but just seems slightly off and won't click when cocked can't see what that could be
They are really fiddly to assemble to say the least. Are any of the parts in the action showing signs of wear of the edges of the metal surface looking rounded off.
@@MrDazP1adv3ntures will take apart again today and have another look... thanks
Good job on difficult item
I enjoyed the challenge of learning how to put this back together Paul. Needless to say there was some cursing along the way too.
The dreaded Scorpion circlip has defeated many owners and driven many more mad who get as far as refitting it.
This can be a tricky job Sindento, especially if your eye sight is failing.
And there’s me thinking a BSA was a motorbike😂
BSA are a well known bike brand and they make some excellent modern air rifles too nowadays. I am still not on the bike yet ! So no videos in that department Sophie. I weighed myself today and I'm at 85kg lol which is a few g more than I was in February. Hope you are still safe and well.
MrDazP1 safe and well thanks Daz. I’ve sort of early retired as I’ve asthma and therefore returning to work, it’s not an option. So out on the bike I go. I’m working towards my century and should have it in the next month and now average over 15 mph on longer 50 mile rides. You were correct improvement comes with time. Still riding solo. Any advice welcome as regards the century. If you reverse your weight you have mine 😆. Trying to ride 4 times per week. Weekends and Wednesday’s off. If you get out now cake café stops are not an option so the extra lbs will melt away like a Cadbury’s choc bar in the sun.
No pressure to film your rides. I like watching your back catalogue. Stay safe yourself to you and your family.
15mph ain't too shabby at all. Keep building up your endurance ability and listen to what your body is telling you. May be look at a 75 mile ride and then back to a few 40 milers. It looks like a 100 mile ride with a few rest breaks would be around the 8 n' half hour mark. I would also look after your contact points in the saddle area the more your ride for longer periods. It can be the baine of many cyclists so a good chamious cream is essential.
I think you will know when you are ready. I would plan a route with a tail wind for the return leg too.
Happy training and all the best.
MrDazP1 I did a relatively flat 73 miles 10 days ago. I’m planning 80 or so for next Monday to Newby Bridge and back. Also did the Trough from my side to Dunsop. That was on my list. I’ll take on board all the advice thank you. Wind behind on return; best tip of all 😃
Thanks love finding out what acronyms and initials stand for. Favourite funny one is LOTUS = lots of trouble. usually serious 😂
Great vid. Just waiting for Daz to get into airsoft now. We can only hope lol
Hi DEmma, this was a great project and at times it was one of them where you think to yourself, should I have removed that pin lol.... to be honest, it's the fiddly components!! but after a while it all makes sense. Are the Airsoft guns a bit like this ? I've never looked at one.
@@MrDazP1adv3ntures airsoft rifles are a lot more user friendly as it is pretty much accepted that they need to be serviced and also upgraded or repaired. Its most airsofters dream to get a reliable high rate of fire and accurate gun and there are many ways to upgrade.
I guess it down to good seals and O ring parts then. Do you size your BB's and weight them individually for consistency with each shot and then have a " dream " stash of selected ammo.
@@MrDazP1adv3ntures In UK, individual sites limit the joule (energy) to about 1.1 for AEG's which equates to 350 feet per second (FPS) using .2 BBs. >2 BBs tend to not be accurate and most players will use .25 BBs or heavier to get that extra range and accuracy or grouping. Certain gun manufacturers work better with that joule power and a leading 1 would be Tokyo Marui but it does come with a price tag. Most people will start with a lower budget and twiddle and fiddle with parts, upgrade bits and add PTFE to create better seals to gain FPS to meet limits and also to improve accuracy. BBs are bought usually in bottles or bags of about 3000 which may last a day or 2 and come in weights such as .2, .25, .28 etc. Some brands are better than others.
@@DEmma1972 It's interesting to look at caliber choice because with air rifles the .177 has a flatter curve on the trajectory so in the mid zone of its flight , say 20 - 35m it's relatively flat. A .22 has a more pronounced drop down range and is a bit heavier in weight which carries a bigger punch. Another lesser used caliber is .20 and also .25
>20 is a good in between caliber but as with most conventions the old .177 & .22 are well and truly established.
I never new they had a joules rating for airsoft either but it makes sense. 350 fps is pretty good going .
Thanks for sharing the info.....
Bought this pistol back in the seventies and just dug it out from attic. Found to be completely seized so stripped down. Have got as far as removing piston but head assembly still in chamber , any idea’s on how to remove piston head. Many thanks and great tutorial
You might want to try to get some freeing oil sprayed in there and left over night to get right in the nooks and crannies. If you can see part of the piston body tap it out with a wooden drift. It will be the perished buffer washer causing you the problem.
Try and put a thin steel rod down the transfer port and gently knock piston head out you may after remove barrel, i had the same issues
I took mine apart when i was 16 and could never put it back together again I used to have to take it to the local gun shop to get it put back ..After doing it 3 times the guy in the gun shop said dont take it part again cos im not gona fix it again
Ha ha, that's a funny story Brad,
I was always told, if it ain't broke then don't fix it but that's human nature I guess
Nah i was trying to put a thicker spring in to make it more powerful i was nver satisfied with the power of British airguns @@MrDazP1adv3ntures
Nice video daz full on strip down and complete rebuild not a job I'd like to tackle my uncle used to build model ships replica of the titanic and such and the detail was unbelievable but he had on trait if you ever asked him to fix anything he'd say no carnt get it working then I'd say oh well just keep it then hey presto not only fixed but for sale lol
You need a lot of time to invest on these projects Simon and because I am off the bike at present it frees up 20 hours a week to do something else. It's a gold panning video next so I need to get the editing software fired up again.
@@MrDazP1adv3ntures great news il look forward to it mate
@@SMITHYSKONTIKI it's not too far from your neck o' the woods.
@@MrDazP1adv3ntures il keep a beady eye on the spot then lol don't take it all😁😁
My son repaired my Scorpion, and the barrel does not latch completely in place after being cocked. Still fires, but the air seal leaks (of course). Is there a fix for this? I sure hope so!
Hello John, I will have to look at my Scorpion to see what the issue could be. The key factor will be the breech seal no matter what. I will get back to you . I'm not a gunsmith by any stretch of the imagination, I'm just an enthusiast but I if I can help I will always try.
Hello , just been giving one of these . I can only partially break the barrel. It then hits some sort of resistance. The safety/fire lever seems to be loose with no resistance as well . Any advice would be appreciated Is there a set service kit you can purchase for this ?
enquiries@airgunspares.com (John Knibbs international) These people may be able to help you.
Have you tried to hit the barrel with the palm of your hand wearing a glove to overcome the resistance.
It could be the piston seized in the cylinder
@MrDazP1adv3ntures thanks mate , stripped it down today exactly how youve shown. Piston was very ceased ! Which has caused a major issue. When removing the retaining ring and washer came off leaving the head / buffer washer inside right at the bottom 😡 thing i might be a bit screwed no idea how i will get this out now !
Thanks
Can you get a long drill to make a small pilot hole and then get a self tapper attached to a thin rod to the try to slide out with the screw embedded into the head , if you know what I mean.
Is there any way of using a rubber mallet to hit the cylinder and create a reverse shock effect that will move the parts upwards towards the opening.
@MrDazP1adv3ntures its out ! Buffer washer was completely perished pretty much fused to the piston head.
I got a rod on the lathe drilled a 9m5 hole in one end which was a good fit over the piston head shaft. Then with alot of wd-40 and some wiggling i got the head moving. I then used a airline and fire air down the small exit hole whilst continuing to wiggle. Came out lovely!
New parts ordered today. I will let you knownhow the assembly goes. Got a bit of cleaning to do first.
Thanks again !
Great news !
I am well chuffed for ya. From memory, its a challenge to dismantle the the whole of the internals and trigger etc, I needed standard X2 magnification glasses just to see what was going on but it was so rewarding to take it apart and for it to work again.
Please keep me posted 👌
I've got a BSA Scorpion
I bought around 1980 new,
It's working and in very good condition,
But I recently went to it, and the safety catch prevents me from firing it?
And now it's currently always loaded?
After watching your video, I'm now worried about touching the trigger assembly?
I live in Selby Yorkshire,
Is there any chance I could get it to you,
I would pay you to put it right for me?
I could send you my email,
For future details,
Cheers Paul 👍
Hi Paul, I'd recommend going to a local gun shop, there's a few in that part of the world.
Does the barrel break if you hit it with the palm of your hand.
Since posting this,
I've got it working again ✌️ HUSSAR 👌
Great news 👍
Look after it, they go for a good price nowadays
Great video, it gave me the skills to dismantle my ancient, seized Scorpion. I’ve received all the replacement parts but I cannot get that damned circlip off the piston head. Bought a new set of picks but I can’t get any kind of movement from it. Any suggestions welcome, otherwise I’ll have to saw off the piston head and replace that too.
Hi Mike, it will go with a bit of brute force and you might even think that it's not a split spring clip because you can't see the section where the two ends meet. I needed good light and some glasses to sharpen up what I was looking at and then tried to twist it to form a kind of helix or spiralled action up on the shaft. It did go in the end and was slightly deformed but it was good enough to be tapped back into shape afterwards and re used
MrDazP1 thanks Daz. I bought a replacement circlip so I know the split is tiny. So far I’ve bent the tips of two picks. May need to buy better quality ones.
@@mikefranks816 A nice little flat bladed screw driver might help to prise the opening apart, or you could try to use a punch and tap the centre piece of the piston through to see if it dislodges the retaining ring. It sometimes helps to walk away and have a brew too.
MrDazP1 brute force it was - hammer and a small chisel. Now for the rebuild. Thanks for the advice
@@mikefranks816 Great news Mike. If the trigger mechanism is working then leave best alone though.
Hi, just watched you video and I was wondering where you got the parts for it, would appreciate if you can send me a link. Thanks
I think it was from John Knibbs international Jay
@@MrDazP1adv3ntures thank you..
And yes...I have a scorpion that only just opens
Could be a perished piston seal pal
