  1. Twist rate won't matter much if it is close range. In case you need to come up with a strategy to lure it in...
  2. I mean, why not once you don't have to eat the tax.
  3. Is there really much point in suppreing a 5.56 pistol? Subsonics are basically expensive .22's, and by the time you add the length of a suppressor is it really much quieter than a rifle length gun?
  4. I have a purpose built dryer. It's good for keeping nylon from absorbing moisture during a print, but pretty much none of them will get up to the 90-100C required to actually dry it.
  5. I finally finished my suppressor build this last week, after several frustrating issues printing with PA6-CF. The first attempt went admirably until about 30 hours into the print when a pop up lightning storm cycled the power with just a few hours to go. I didn't have enough filament left on the roll to try again, so I ordered another roll of filament. When it came in, and I went to dry it in the food dehydrator I'd ordered just for this purpose the screen just blinked on and off. After a bit of investigation, I was unable to find any blown fuses or anything obvious wrong with it, so I tried drying the new roll in the oven. The oven clearly didn't keep a proper temperature, because my subsequent print had some spots where it had moisture in it, and was too warped to line up with the bore. Eventually, I was able to get a decent print that seems like it will work. While the core is printed, it has an aluminum tube that reinforces the Z axis and keeps everything from blowing apart. JB Weld is used to bond the tube to the core. A Breek Castle Shield is pinned into the printed core with hardened steel rods to allow it to thread onto the flash suppressor without blowing out. The aluminum tube holds it all together. This is my deer rifle when I'm not fooling around with my flintlock, and I still haven't had a chance to test it out and zero the rifle with the new suppressor. Im working this weekend, but hopefully I'll get a chance to check everything out on Monday when I am off. Until everything checks out I guess I'm going to be hunting with the front stuffer. Anyhow, here is the Pic, it's a .300 BLK rifle with a 10.5 barrel (amnesty braced lower) plus the FTN.4 suppressor. Everything was properly Form 1'd through the ATF for this build and the approval took just over one business day. With the tax for a Form 1 suppressor going from $200 to $0 on January 1st, I can see this being a viable alternative to commercial suppressors if everything works out as it should.
  6. I've heard of folks back in the day who were supposed to be walking pipelines getting lost by following their boots. I guess that's one of the reasons why they put up signs now.
  7. I hate when I find out afterwards that an episode was a season finale. Especially when I'm looking forward to another episode or two.
  8. Elkhorn is nice B western series. The acting and cinematography leaves a lot to be desired, but it is still entertaining. It is about Teddy Roosevelt's early years as a cowboy. Go into it expecting cheese and you will enjoy it. Go into it expecting Deadwood and you will be wondering WTF?
  9. Lol, I originally bought this printer with a gift card I won through a United Way raffle at work. I had been interested in 3D printing for a while, and given the option of choosing a $600 Walmart gift card or a $600 Amazon gift card I realized that if I got the Walmart card it would pretty much go into the general family fund. Of course I noped out of that and chose the Amazon card so I could do some 2a prints for cheap and make a suppressor for little more than the cost of the filament, as I'd been monitoring the development that other folks had been putting time into. Now, I've bought a dehydrator that crapped out after the first use, a filament dryer that suffices to keep nylon blends dry enough for the time it takes to make prints of sufficient accuracy, and you're very reasonably suggesting a UPS. I don't think I've saved any money at all. Now I'm left with the consolation that I could get an FFL and an SOT so that I can work on designing and developing suppressors to make all this worthwhile. I don't think the wife is amused, she already thinks that basically PPE is some kind of boogeyman.
  10. So, for some reason, the Polymaker PA6 spools have a meter scale on the side cutout instead of a gram scale. I had a little over 50 meters left on the spool, which at the 2.81 grams per meter that Google's AI calculated for me, means I'm gonna hit the runout sensor about halfway through my reprint. I've got more filament supposed to be here Friday, but it will need to dry (my dehydrator that I bought for this died, so I guess I'll just have to bake it in the oven) for half a day or so before I can even start the print back. Fingers crossed that there aren't any power issues or one of the kids doesn't unplug it, because I don't think there is a way to save you spot if you kill power to it, and this stuff is already $40 for 500g.
  11. That's a whole order of magnitude higher than Polymaker's PA6-CF! I'm not sure the cost/benefit analysis is going to be in it's favor for anything but the most technical of uses.
  12. From what I've seen, it does experience some deformation under high rates of fire, but not enough to render the suppressor unservicable. For slow rates of fire like it would see from sighting in and hunting with a rifle I believe it does pretty well. Of course these suppressors were designed with it's limitations in mind, so they are pretty beefy. This PA6-CF stuff I just pulled off, however, is pretty rock solid, even without annealing or moisture contioning. I'm not sure I could smash it with a hammer. I'm hoping I have enough left on the roll to reprint it by the skin of my teeth.
  13. ...and over 24 hours into a 32 hour print, a storm rolls through and cycles the power just enough to cause my printer to reboot when it was this close... Hopefully there is enough left on the roll still, because this stuff isn't cheap.
  14. You have to file a separate Form 1 for each device you print, but with the efile system, if you get your electronic fingerprint file done and submit everything electronically it only takes like a day or two to get approved. This suppressor design has actually been able to withstand several hundred rounds of supersonic .308 when printed out of PLA+, so it should last much longer when printed out of PA6-CF. Check out r/fosscad to see a lot of the work done to develop stuff like this.
  15. Oh, I got the form 1 approved a while back, so everything is in order when it comes to my dogs. I wouldn't be printing in PA6-CF if that weren't the case.
