    HollowPoint replied to a thread Gas piston longevity in AirGuns
    I don't think its fair to calculate based on my initial post or reply. Like I said, I basically tortured my first two gas pistons trying to get more power out of them. This included adding some pre-load to the pistons so that when the gun was...

    HollowPoint replied to a thread Gas piston longevity in AirGuns
    I bought my Umarex Octane some time in 2009. (I think) I'm on my third replacement Gas Piston. In all fairness though, the first two were subjected to alot of abuse due to me trying different power mods with mine. I've easily gone through...

    I thought about doing that very thing but instead of printing the feed-lip section separately I was thinking more along the lines of printing the main body separately and fabrication the top-most part where the feed-lips are out of sheet metal of...

    I'm on my fourth attempt at drawing my CAD model of my Lee Enfield extended magazine. Holy Cow! samuri46 was right. Now that I've taken a closer look at my own Enfield magazine and put my calipers to it to measure, these magazines are really more...

    I started drawing up the CAD model for my Lee Enfield No. 4 Mk1 Extended magazine last night. I had never really taken a close look at that particular magazine before last night. It really is a little different from your standard rifle magazine,...

    I just finished up the last 3D printed addon to my K31 rifle. I figured since I'd made a functioning extended magazine and a set of peep sights I should also try making myself some Stripper-Clips as well. I have two factory Stripper-Clips in my...

    Ten hours and seventeen minutes later and I have what now appears to be the 3D printed Magazine I was after. I actually attempted to print this latest iteration two days ago but it just would not print correctly by sitting it directly on the...

    I did all the slight modifications in the geometry of my Magazine CAD models last night and then I set it up in my Slicer software again. This time I laid it sideways instead of standing straight up and down standing on its' base as before. This...

    Thanks for the encouragement you guys. I'm afraid when I post stuff like these projects it tends to highlight only the successful parts of the project stages. With the extended magazine project I've printed four different iterations already. The...

    With my first attempts at printing with my particular printer I had similar results as you've described. I had to do alot of experimenting with the print settings to get where I'm at now. I found that the suggested settings offered by the...

    I think I've owned this printer a little over a couple of months now so my CNC hobby mill has sat idle for that long. I used to do my prototyping with my Tormach 770 mill but now, even though these prints take a long time to get done, it's still a...

    In the mean time here are some of my CAD Renderings of the K31 Swiss Reciever Mounted Peep Sight I've been working on for my K31 rifle. I've actually already printed out a prototype set of this Peep Sight design and everything appears to be fitting...

    Another seven hour print, this time in Carbon Fiber and the finished results was a very good surface finish but from feel alone it would seem that the Carbon Fiber Magazine body is actually not any more inflexible than the ABS magazine body. I...

    I have yet to experience any real loss of accuracy out of my Gauntlet. I have experienced this with my other air rifles which was caused by dirty barrels. I guess I'll have to develop a routine of cleaning my barrels periodically. I've usually...

    I'm sorry if I sounded like I was accusing anyone here of being a "Self-Appointed-Know-It-All." Generally speaking the castboolits forum is one of the most idea-friendly internet sites I've ever come across. I think this is in large part because...

    I finally got the Carbon-Fiber 3D Print filament I ordered off of Ebay about a month ago. Now I have to figure out the correct temperature settings to get it to print the way I want it to. These filaments generally come with recommended...
