Just might make bits easyer for some people. _________________ BIG GAP   Posted: Sun Jul 08, 2007 5:11 pm leadman Veteran Member Joined: 10 Feb 2007 Posts: 215 oops i had ment to do that but got carried away so after 5 minuits of highlighting, 5 minuits of cleaning off my monitor and another 5 minuits of highlighting in microsoft paint here they are :D just about any surface where there is metal on metal contact you need to polish _________________ http://www.getphpbb.com/phpbb/index.php?mforum=huntingcanada   Posted: Sun Jul 08, 2007 5:14 pm broommaster2000 Moderator Joined: 10 Mar 2007 Posts: 5714 Location: City of Groningen, Groningen, The Netherlands Tarnation!

That cancels out any mistakes along the line. I studied to make manuals for 2 years. I quite that study because they teach you to be an a$$hole. Multimedia is much nicer. _________________ BIG GAP   Posted: Sun Jul 08, 2007 5:30 pm leadman Veteran Member Joined: 10 Feb 2007 Posts: 215 yeah the problem is i get an idea in my head and my hands have it in motion long before the idea of a camera gets into my head or the camera gets into my hands _________________ http://www.getphpbb.com/phpbb/index.php?mforum=huntingcanada   Posted: Sun Jul 08, 2007 5:36 pm AirGunEric Site Admin Joined: 20 Jan 2007 Posts: 6930 Location: "Out There" Highlights and arrows are always helpful if someone doesn't have a proper frame of reference! "5 minutes of cleaning off my monitor" har har har. Circled a few places you shouldn't have before that? Now that you're done "polishing your trigger", are you satisfied? -ok, I know, that was probably not appropriate... _________________ ` I'd say "I care." But I'd be lying.

We have a saying in dutch for that, but I don't feel like trying to translate it as it will probably lose it's meaning. _________________ BIG GAP qb78 trigger mod     Air Gun Home Forum Index » Rifles 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."
