Anyone encounter this before? I'm thinking of replacing the plastic washers with brass ones, a bit thicker to avoid this. _________________ Duke ))))----//----------==   Posted: Sat May 14, 2011 8:42 pm Slavia Moderator Joined: 31 Mar 2008 Posts: 4382 Location: Waseca, Minnesota, USA I had some side play on my G1, so I replaced the plastic washers with steel. Much tighter and smoother now: http://www.airgunhome.com/agforum/viewtopic.php?t=1760&postdays=0&postorder=asc&start=15 You can also get brass: http://www.airgunsmith.com/quest/quest.htm _________________ ¡Listo! ¡Apunte! ¡Fuego!   Posted: Sat May 14, 2011 8:45 pm SMP Silver Status Member Joined: 04 Feb 2011 Posts: 1183 Location: Just south of "Out There"- Land O Lakes Ontario Yes right after I tried my phantom with scope I had some issues with the POI shifting. It would shot a number of shots into a group the suddenly shift and shoot a number of shots into a new group then shift again. I can't say for sure that it was the plastic washers but the problem went away after I replaced them with metal and detailed the contact area at the pivot. Thanks for input   Posted: Sun May 15, 2011 10:41 am Dukemeister Member Joined: 08 Feb 2010 Posts: 92 Location: Ontario, Canada I think then I will replace the plastic washers with brass or steel, maybe brass with a good dose of moly. thing is the angle was consistent, it really wasn't loose, just cock-eyed. On a related note, when I was working on my Quest, I couldn't separate the barrel from the receiver, it was as if the breach bushing tube (part #21 ) was recessed into the receiver forks... I tried gentle persuasion, but it wasn't moving so I just put the bolt back and let her be. If I'm going to change the plastic washers on my Classic I'd just as soon do my Quest too. Any ideas as to why the barrel wouldn't come free of the forks? I would have tried pushing on the bushing but it's only accessible on the unthreaded (head side) of the breach bolt. Can't see it through the threaded side... _________________ Duke ))))----//----------==   Posted: Sun May 15, 2011 10:50 am SMP Silver Status Member Joined: 04 Feb 2011 Posts: 1183 Location: Just south of "Out There"- Land O Lakes Ontario Yup I just had the same issue about 30 minutes ago while tuning my CO's gun. There was a significant burr on the edge of the pivot hole. I managed to pry it across but it put a dandy gouge in the plastic washer   Posted: Sun May 15, 2011 12:22 pm Dukemeister Member Joined: 08 Feb 2010 Posts: 92 Location: Ontario, Canada SMP wrote: Yup I just had the same issue about 30 minutes ago while tuning my CO's gun.

Also where is the burr, is it head side or thread side on the forks? _________________ Duke ))))----//----------==   Posted: Sun May 15, 2011 12:38 pm SMP Silver Status Member Joined: 04 Feb 2011 Posts: 1183 Location: Just south of "Out There"- Land O Lakes Ontario Hi Dukemeister The burr was on the thread side. I would post a pic but I'm at work and big brother wont let me look at or upload pics to this site. I keep meaning to ask Eric if there is something specific on here that may be tripping our bot I used what I know as a "catspaw" also known as a mechanics prybar. It is basically an inch long rocker shoe at one end of a bar. I picked mine up at Princess auto. It is the smallest size and it will fit between the forks and apply force smoothly to the pivot area. the link shoes a photo of the pry bar http://www.mechanicstoolsupply.com/pop.asp_Q_poptype_E_2_A_imageName_E_10_2_2007_9_38_15.jpg   Posted: Sun May 15, 2011 1:36 pm AirGunEric Site Admin Joined: 20 Jan 2007 Posts: 6930 Location: "Out There" SMP wrote: if there is something specific on here that may be tripping our bot The fact you can even visit here means your employer's filter is not "normal"- almost every employer-filtered internet access screens out "guns", "firearms" etc. As to why you can access the forum at work, but not post pictures- that is an odd one. It may not be "us" but the photo site- "postimage.org" that is being filtered- which should mean you could use something else- i.e. photobucket or the like- assuming other photo services aren't also filtered out. _________________ ` I'd say "I care."

Scored a deal at True Value Hardware store on a 10 piece prybar kit many years ago while I was doing renos. I'll go look for it. _________________ Duke ))))----//----------== Help/advice on barrel alignment sought.     Air Gun Home Forum Index » General Air Gun Questions and Topics You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum All times are GMT - 5 Hours   Page 1 of 1   All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First  Select a forum Main Forums----------------AirGunHome Q&AGeneral Air Gun Questions and TopicsPicture GalleryTarget Shooting: Casual, Fun and CompetitionHunting, Pest Control, Varminting People/Events/Airgun Issue Discussion----------------Introduce YourselfThe BS TopicClubs/Events/Regional/Political Airgun Issues Maintenance, Modification and Reviews----------------RiflesPistolsAntique, Collector and Novelty AirgunsBB GunsPellets/AmmoOpticsAccessoriesAirgun Smithing Buy, Sell or Trade Forums----------------For SaleWant to Buy   Note: If you are seeing "Please enter your username and password to log in."
