Gunmark air-rifles/ air-pistols

Oiling of washers should be basically between every 2000 shots OR if the washer squeaks when you cock it.

its a single drop for some 100 shots,may be i am wrong but no complains yet...,somehow i feel the leather washer can take a lot of abuse wrt dieselling and is bound to happen anyways, infact personally i felt oiling a leather washer to maintain its softness under small amount of dieselling didnt cause any disaster,and is not as sensitive as ptfe washers which gets scarred within 10 shots if dieseling continues,please correct me if i am wrong.

I Agree with you - 'Dieseling' to a certain extent is very much important for leather washers or else it is nothing but a blow gun. Regarding oiling what i read in an old Airgunners magazine is what i put up.
I use singer sewing machine oil for the washers and they do the job well.

@Emery: I dont have pics with me. The Gun is not here with me. Its in Dubai. I'm here only since 3 months. The only guns I have here are the Crosman 1377 Classic and the Local GI Rifle. I was not aware of the customs formalities and hence decided against getting the rifle. As for getting it to Dubai, It was shipped by PyramidAir to a friend in Tx and he and his dad brought it down. The gun was dismantled including the barrel and brought by 2 people to avoid any problems.
The aluminium stock did not have any issues either. Only problem was with the Air cylinder which was cheked by customs in the US. Nothing in Dubai. As for the 1377, there is nothing in it to be dismantled. I just packed it, left it in Cargo and it arrived safely. No questions asked. I landed in Kerala. Not Bangalore.

But the best thing to do for those of you interested in buying a Condor would be buy a Talon SS with the .177 barrel, get the Hi Flow Valve (Canister Included) have it shipped here

@Mundaire: I get the idea.. But I'm not a member yet of any club. I called KSRA three times and all three times the guy in charge was not there to help me. So I gave up. I hate it when these people act like they're doing us a favour. Its not free either. And work keeps me busy! Another problem is that i'm not a big fan of .177.

@Sanjiv: The Leather washers are supposed to be bloated at all times for optimum performance. Thats agreed. But they use special oils that prevent excessive dieseling. Also these oils are hard to find since not many rifles leather washers these days. Every spring rifle utilises dieseling to achieve their full power. But oiling every 100-200 shots is a sureshot way of screwing up the seals or more. But i'f using oils that control dieseling, then alls well! Also, the leather washers can take the abuse. Bujt what if the powerplant develops a crack? The trmendous pressure generated during detonation will blow the rifle. Especially local ones.

I am a big fan of dieseling. I love the spectacular report and the destroyed pellets. Once you get the right mix, you can control accuracy as well. Get some ether from a chemist and find the mix, usually 1 part ether to 6-8 parts lubricant to get controlled detontion. The lube is not moly grease! It should be something that can be drop-dispensed directly into the port. I like Crosman's Pellgunoil. Its smooth enough and mixes well with ether before it evaporates, This is only for magnum rated air-rifles though. My Hunter has been dieseling away to glory since the last 6 years and no problems yet. Seals and springs have been changed, but no other major damages.

I'd suggest you ease off on the lubing part till you get an oil that wont diesel. I know you will miss the dieseling. I will too!!

Mo, do not post any more dodgy suggestions on this board. I have been editing your posts since you have joined but henceforth the entire post will be deleted rather than just edited. Mack The Knife.

The IHP/ National Model 25 I bought for my son last year came with a synthetic "parachute type" washer... I would imagine the same would hold true for their Model 35 too... They also seem to have the best rifled barrel of any Indian made air-rifle - that I have seen so far. Of course their products are far from perfect (the trigger is horrendous for one), but I still consider them the best Indian made air-rifles in the market... also their prices NOT too high - IIRC circa INR 3,000/- or so...

hi mo,
thanx for all the concern,which seals wud get screwed up ??? anywayz, i am quite sure about what i am doing to my rifle and how much to lube,its not that i am looking forward to intended dieselling or i wud not love to get rid of it but its just not possible,a drop of silicon oil does not lead to detonation nor does it diesel mildly for more than 5-6 shots ,it ofcourse has higher flash point than any gun oil or petro based oil.
show me one indian made rifle that consists of a ptfe washer,i cudnt find any?none around me

,they all have the leather piston washers .and that is why in my first post in this topic i had asked the gurus how to go about changing it to teflon based piston seal.

nb-in my hw75 its been more than 5000pellets and not a single drop of any oil was used.,and with more shots its getting better by the day wrt to when i got it new., lubing is a big serious theory for airguns,atleast i understand that from all the relevant posts of the past ,and it all depends according to different powerplants and component materials been used.
cheers sanjiv

same here not affiliated with gunmark either

,and a spade is defi. a spade,pls do have a look on the barrels of the national and the gunmark,before deciding atleast on the best rifled barrels,from an indian made airrifle.
--do the present ihp's also have synthetic washers(may be they are not ptfe seals like those found in the imported rifle plants)?are they better than the leather to durability.
thanx for the correction.
regards sanjiv

The Piston Seals of course..

If the flash point is high enough, then dieseling wont be a problem. Thas the reason, its working fine for you! lol.. I assumed it was regular gun oil. I saw a local one retailing for Rs. 15. They look like they're designed for dieseling! he he.

Where did you get the Oil?

Also, I spoke to Mr. Kulkarni from GunMark. He said that the rifle has synthetic washers and not leather one. Maybe thats a change in the new ones. Did you see the new rifle he's selling? Is it the same as yours? Can you check?

speaking of synthetic washers - howz the punch compared to a leather washer thats dieseling (within limits)
Havent used a synthetic washer so not able to comment on it and also havent been able to locate one here _ bangalore

Post by **eljefe** » Tue Jan 22, 2008 11:36 pm

Guys, why cant you turn out PTFE/teflon washers?

It's highly dependant on the design & tolerances on the washer/ seal. The parachute type design (with tight tolerances) would produce the maximum amount of power, all other things being equal... and that is what is used by pretty much all modern spring piston air-rifles...

@Mack The Knife: Hey, Sorry bout that. I hadn't seen the edit till today! I didnt know that my posts were messed up. Was it the part about the controlled dieselling that warranted the dodgy suggestion tag? Point me in the right direction and I'd be glad to oblige. If any of my posts require editing, lemme know and I'd do it. It was far from intentional! I dont want to start off on the wrong foot!!

Thanks and Apologies,

Mo.

Many thanks
