That looks really good - crimp groove looks just right. Tell us about making the mold - aluminum? Steel? Brass? and how you machined it.

212°F is boiling distilled water at sea level, or close enough anyway. I just found this link:

Isn't he the guy who had the .50 cal failure a few yr back that actually cut his jugular artery? Survived by holding his hand on wound while his Dad drove to hospital?

Even in my young 'n dumb...

Thank you for the files, and THANK YOU for the scad files. I like having the paraments allowing to change the file.

I've got a Westinghouse 15KW dual fuel generator. With gasoline it's 15KW surge, 12 KW running. On propane it's 13,500 surge and 10kw running. If you're pulling 9 or 10 KW you'll never really...

This one isn't gun related, but still a handy little stand for the TinySA Spectrum Analyzer I got a couple weeks ago. The black strands on bottom are where I didn't get the last black filament...

@flemdoug: I'd love to take you up on the offer but since the city moved city limits to adjoining my property and built a subdivision adjoining my property I don't get much shooting in. Totally...

That's a very good design and very useful. Congrats.

There is a forum for suppressors called silencer talk, I think a quick search will turn it up. LOTS of good info there.

That's what I was thinking - 5 minutes tumbling? 10 minutes? After that much time I might forget I'd put them on the tumbler and see them next day :)

I'd be happy to print them for you, "IF" you can fine the .stl files to print with. I'm not good enough with 3D CAD programs to draw them up myself, and don't have the required pistol to get...

Looks like it takes about 20 to 25 minutes to print, depending quality of print. "High" detail is 30 minutes, while "rough draft" is only 16 minutes. I usually print stuff in "normal" which is...

Yep, thread is printed in, just screw on. It's a tight fit - on a couple of the nuts I chased the threads with a tap to make them screw on easy with finger pressure. I think it's better to leave...

I think you've settle the value of 30-1 RM just fine. Thank you for spending the $200 for the test, not sure it's really worthwhile to spend even more money to confirm what you've already found out....

While I do enjoy finding useful things to 3D print, I do think I'll pass on those caps.

Agreed, looking forward to a hobbyist level metal 3D printer.

Shopdog, could you provide more info on that hardness tester? Looks interesting, but looks like it uses a spring for pressure rather than weights? I use the HR150A clone for hardness testing. It's...

I thought I'd post the loading die lock nuts I printed. I've been pleased how well they work - sorta tight to screw on, but that prevents them from moving since they don't have setscrews to lock in...

That sums me up about as well as can be. I just enjoy "tinkering" more than anything.

Good job on that Roller - 45-70 is a good caliber for a roller

Like Don I learned something new today. One of the reasons I enjoy this site so much. Always learning something new and interesting.

That looks like a neat tester - I just ordered one, should be here Friday.

An excellent book. That's where I first learned about "real" air rifles. I had no idea they had been around so long.

60 Rc is a good place for a knife- still fairly easy to sharpen and will hold an edge

Nice job, and the wet formed sheath looks good. That should last a lifetime

Glad it worked for you. Anytime I can help, just holler
