loopy bunny blaster Posted August 15, 2007 Report Share Posted August 15, 2007 NO! fit it in at the current length, or you will weaken the spring, chrono the gun after and if its overpowered take in to a gunsmith in the morning Quote Link to comment Share on other sites More sharing options...

loopy bunny blaster Posted August 16, 2007 Report Share Posted August 16, 2007 make sure the barrel is in line with the stock in the shooting position for a start, and use both hands to push it in. then replace the other components. Quote Link to comment Share on other sites More sharing options...

berettaman1 Posted August 18, 2007 Report Share Posted August 18, 2007 Hi Bud, I suggest you take a look at the face of the cylinder of your HW35 when you cock it, The locking catch on that model over time wears a vertical groove on the the cylinder face, which encroaches where the the O ring seal in the barrel closes down on it, you might require a new seal, failing that, carefully remove the barrel seal ( with a stout needle) and pack out the O ring groove with a circle of white string, and replace the O ring, rechrono and if the power is up then you require a new O ring!... cheers Bud, Over the last 35 years I have worked on dozens of HW models so my advice is true.

loopy bunny blaster Posted August 19, 2007 Report Share Posted August 19, 2007 have you given the barrel a good clean? Quote Link to comment Share on other sites More sharing options...
Guest rabgoat Posted August 19, 2007 Report Share Posted August 19, 2007 have you given the barrel a good clean? no i havn't cleaned the barrel at all,iv'e just recently got the gun it's a rough old thing,but looking down the barrel it's shining like a shilling,i didn't think that would make much a difference to the power.but i'll give it a go Quote Link to comment Share on other sites More sharing options...
Guest rabgoat Posted August 19, 2007 Report Share Posted August 19, 2007 have you given the barrel a good clean? just cleaned the rifle using a method i seen on PW watched recently,using rizzla rollup tips soaked in parker & hale 009,i thought the barrel was clean,i couldn't believe the lead came out of it.,,well it did improve it by nearly 1ftb,it's better than nothing..thanks for the advice lads.

08shooter Posted August 19, 2007 Report Share Posted August 19, 2007 check the barrel o ring that its not worn Quote Link to comment Share on other sites More sharing options...
loopy bunny blaster Posted August 20, 2007 Report Share Posted August 20, 2007 1ft lb's we're getting there! lol only other thing i could think of would be to take the gun apart and clean everything, including the spring housing and see if it makes a difference.

berettaman1 Posted August 20, 2007 Report Share Posted August 20, 2007 Ime wondering if the head washer is ok? if its a real old HW they used to have a leather piston washer fitted in the 1950,s and i960,s if its a later model late 70,s onward they changed to the nylon head if its nylon check that its not had a scollop nicked out of it, if its good you should be able to put your finger over the transfer port (when down to just the cylinder and piston( insert piston down to where the seal is just into the compression part, put finger over the trasfer port and press the piston down if its not leaking air you will feel the resistance, if you can push the piston all the way down then the washer is cream crackered. cheers bud.

Guest rabgoat Posted August 26, 2007 Report Share Posted August 26, 2007 I stripped the gun down today,got a guide from (henryd) on the hw35 it was of great help.a lot of info on cleaning etc.thanks again hd well the head washer is the nylon one it seemed to be fine,covered the transfer port and pushed down there was no loss of air anywhere that i could see,i couldn't push the piston the whole way down,totally degreased everything cleaned rite down in the cylinder,i put the gun back together and the first shot with eley wasps was coming out at 20ftb then the next 4 or 5shot were around 17-18ftb, there was noticebly a bigger kick out of her,then it suddenly dropped to around 8ftb,it seems to have settled down at this Quote Link to comment Share on other sites More sharing options...

Guest rabgoat Posted August 26, 2007 Report Share Posted August 26, 2007 i was wondering why it smelt like there was a fire lit inside the cylinder,it was dieseling,the iv'e just fitted is a new ox spring would the titan one be any better,i don't think the hw35 can be fitted with a gas ram can it ? thanks berretaman1 Quote Link to comment Share on other sites More sharing options...
berettaman1 Posted August 27, 2007 Report Share Posted August 27, 2007 no dont use any of those springs, in my opinion they are ****,Sandwell Supplies sell a very good own make spring which is excellent, and is only about £15.00,? you will not get much more than 11.5 foot pounds with the HW 35 ,due in the main to it having a long transfer port , however they are smooth to shoot get in touch with Tony Wall who is the tuner at Sandwell supplies he is a honest bloke and will advise you , yes your right. the HW35 can not be fitted with a gas ram cheers bud. PS I have just had a thought if your gun is .22 and you are using Wasp ammo then remember wasp do 2 .22 sizes 5.5 and 5.6, if you are using 5.6 then they are too tight in the HW35 bore, try some H&N or RWS ammo.
