Sure, we'll meet up over a cold beer and discuss this in detail... meanwhile let me tell you what I was thinking of... so if you have tried any of this it would be great if you could relate your experiences here for the benefit of others. This is mostly based on stuff I have googled in the past few days, as my own exp. with airguns is rather limited.
1) Deburr & polishing all moving parts, including the inside of the cylinder (with due care of course).
2) Replace the mainspring guide with one fashioned from PTFE/ Nylon.
3) Add a PTFE/ Nylon washer inside the piston, where the mainspring rests.
4) Replace the piston washer with one fashioned from a Teflon/ PTFE rod.
5) Give the inside of the cylinder a thin coat of Teflon based engine oil additive. This was desrcibed by an airgun tuner on some forum - what he used was something called Slick 50, equivalents are available in India and should be decent substitutes.
6) File and sand both ends of the mainspring so as to make them as perfectly plane and smooth as possible.
7) Add thin plastic washers to the barrel assembly to compensate for the steel shims which are missing in the IHP models.
This is just some of the stuff I have come across as mods that could be (relatively) easily tried out on the various IHP models.
Do let me know your thoughts.
Others, please do jump in with your own suggestions/ thoughts on this. I don't expect to make this into a mean magnum... that it will never be! But I am sure it can be made to shoot sweeter and smoother than it is capable of in stock trim.
Cheers!

-brings back memories of old.Wonder If I can transfer the scope of your airgun(the one thats lying with me!) onto the new one Dev?

I want a 22 IHP
Are prometheus 22 pells still being made?
Will be a willing party for the tune up polishing-I've some some teflon based dry film spray lube and some Moly grease too, so please scream if you want.
Deburring and hand polishing-sure , let do it!
best

have you changed your mind about the advice, or have you caught up in the enthusiasm? 
and no clue whom to approach... 
Bring it over to the "IHP tune think tank" sessionAnupam";p="13857 wrote:I have an old .22 from a unknown company called SAVAGE ... but that was childhood... !! Still works but the sights are miserable...
... and lets see if anything can be done to get it going again... If just the sights are the only problem, that could be rectified by using replacement sights from the IHP parts bin, if they fit...mundaire";p="13805 wrote:Asif,
As you can see... the minor hiccup has been rectified...
Back to the topic on hand - sure lets all pool in our talents/ resources and get this going. Have located a vendor each for Moly/ Teflon lubes and Teflon/ PTFE rods. Now I just need to call them up and start the process of procuring some of the raw materials... Will be sure to get enough for at least 3-4 air-rifle projects... maybe more, if the wholesaler insists on selling me a minimum quantity...
Will update you guys as things progress, we also would need the services of a good machinist - to shape the spring guides and piston washers... any chap with a lathe, bench drill and basic skills on how to use them would do... so if you know of anyone close by....
Cheers!

Not decided yet... I guess we all have a few things on our plates... but soon, very soon - will co-ordinate with everyone..."IHP tune think tank" session
WHEN AND WHERE ???
Yep, that's where I had gone... they are the distributors here and they stock some spares too... for some you will have to order before hand and then wait... ditto for the more exp. pneumatic air-rifle model and the CO2 air-pistol (2 months est. waiting period for the last twoAbhijeet,
Did u visit the Rani Jhansi Road outlet of IHP ? If so, do they sell spares too ??? If not, I'll go there and enquire... u r welcome to accompany me, if u like...any time convenient to u....
). Sure, we can go together, I would like to buy a spare spring for the IHP 25 anyway, since the one it came with is now in my nephew's Diana 25... will pick up a couple of piston seals too... lets plan for mid/ later this week... call me!Very different tools, very different uses... only a minor overlap - and that would be for (small) pest control... I would say get both!I am motivated to get a air rifle with a scope instead of a .22 IOF rifle... feel its more practical and usable... {comments ? }
I hadn't shot an air-rifle in ages (more than a decade) till I recently started teaching my nephew how to shoot... I'd forgotten how much fun it can be... it's a fun "toy" to have, without any doubt! And importantly one that does not use up one of the precious 3 slots on your arms license. At the cost of sounding repetitive... get both... get both... get both! Will do sir! But just replacing the spring guide is not likely to cut it! If you want I can in stead get a spare set of all the drop in parts we decide to have fabricated. Right now those would be, a top hat, new spring guide, thrust washers (these will probably be some ready made variety of the right size etc. that we can find), piston buttons, barrel assembly shims, new piston seal, and an improvised breech seal.kanwar76";p="13964 wrote: Hi Abhijeet,
While you are at it.. Can you please get one spring guide made for me also? Got a National35 which desperately needs a tune. Will pay for the same.
