Even someone with a very basic set of hand tools can make parts out of Delrin, whereas steel can be more of a job to get done properly. Another issue, as you mention, is the weight. Delrin is lighter than aluminum, so it wouldn't effect the rifle mechanics in any significant manner. I guess there's one way to find out how well steel will work- try it! _________________ ` I'd say "I care." But I'd be lying.

Use "Tyvar" its a PTFE...Its so slippery yer can't file it.. if useing a lathe make yer last cut big...as yer can't / hard to take anything under .2mm off just to slipprey and the tool won't bite..just rolls over it....its as slick as a wet XXXXX Has a very high oil content and is self lubeing.. But don't try and make a nylon guide with out a steel internal shaft as the side load of a compressed spring can cause it to brake...nylon sleave over a steel guide.   Posted: Wed Apr 22, 2009 10:10 am Alstone Moderator & Site Supporter Joined: 01 Mar 2007 Posts: 4139 Location: Linconshire, ENGLAND Delrin is ok to make spring guides out of and like Eric says it’s easy to work with, but it does have some drawback's it wears out quicker than steel, it bends and will not stop spring harmonics, it doesn’t like lubricant’s and if you use a lube it will wear quicker, and lastly putting in a light weight delrin spring guide where it normally sits behind the spring and piston, doesn’t help to counter the weight of the spring and piston, where as a heavy steel guide will. So take your pick Al _________________   Posted: Wed Apr 22, 2009 6:57 pm TONBON Veteran Member Joined: 02 Jan 2009 Posts: 468 it's setteled then i'm gonna find a good peice of stainless, and have my buddy copy the print i give him. i guess i'll need to give up the fun i've been having shooting, and actually take it down and start on it .   Posted: Thu Apr 23, 2009 8:57 pm TONBON Veteran Member Joined: 02 Jan 2009 Posts: 468 OK, it's apart. prints made. and so it begins...   Posted: Sat Apr 25, 2009 9:43 pm TONBON Veteran Member Joined: 02 Jan 2009 Posts: 468 (not a great pic)..butt new guide and washers(before lapping) i can see on my piston seal that ive had some combustion. just a little discoloration, but i'd like to replace it while i've got it apart.   Posted: Tue Apr 28, 2009 5:29 am TONBON Veteran Member Joined: 02 Jan 2009 Posts: 468 woo hoo. lube arrived today. pellets tues or wed. i have no chrony, so all results will be bsed on feel and accuracy alone. start reassembly after work.   Posted: Tue Apr 28, 2009 10:43 pm kanyon Silver Status Member Joined: 09 Aug 2008 Posts: 1582 Location: New Zealand Looks good..has to be a improvement over the standard guide.....   Posted: Wed Apr 29, 2009 8:24 pm TONBON Veteran Member Joined: 02 Jan 2009 Posts: 468 OK. all together. about 50-60 pellets thru it. i bought some daisy's to run thru it and break it in a little. my pyramid order. FTS and Predators came today. i couldnt find a slightly thicker brech seal, so i shimmed the existing one. just a little. after the shimming, i needed to resight. i took it apart, put it back together, and adjusted the scope about 2 clicks to be on. before shimming. gotta like that. i think at about 100-150 pellets, i'm gonna open and up and evaluate my lube job. after the internal work, and the shim job, it definitly feels better. accuracy seems about the same, at the moment. maybe a little better. i can tell it needs a little more tar. i tried to go sparingly. i wanna see how the new peices are wearing first. i like this gun.   Posted: Sat May 02, 2009 2:44 pm TONBON Veteran Member Joined: 02 Jan 2009 Posts: 468 Holy moly, i took it back apart and replaced the washers w/ ones a little bigger. added more tar. cleaned up some excess moly. this is a different gun now. almost a thud. shootin' sweet.   Posted: Sat May 02, 2009 7:49 pm TONBON Veteran Member Joined: 02 Jan 2009 Posts: 468 ahhh yeeesss. the 3 will fit in the poptop. 50 ft. much better,,,,just a little more humor me     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."
