Nope. This post has nothing at all to do with litter.
Just sprinkling facts pertaining to recent days.
Got an MRI on Thursday to see what the $&^%^# is going on with my #*@^%)_# neck. What was very interesting was that a 1.5Tesla b-field warms your neck like a drumstick in a microwave. I’m the Bones McCoy type – transporters would make me wiggy and while I know the MRI is a safe machine something that makes me feel warmer when it’s making LOUD noise and I’m crammed in it with no wiggle room – well, it makes me wiggy.
Saw Cars 2 today. It was savaged by RottenTomatoes but honestly I enjoyed it and I feel like people need to freakin’ relax. They are slamming it as if it were a bomb performance by people who are normally academy award winning caliber. Cripes, people, it’s a Pixar movie. No, it is not their best, I get that. But seeing a General Dynamics LCS go kablooey kind of made me grin. And the modeling of the ocean waves was some of the best I have ever seen. My jaw was hanging down and I was drooling, I was so taken in by the excellence of the rendering. A bit long but fun. Kids liked it.
Oh yeah… I’m designing a steampunk gun – a real live take-the-fur-off’n-that-yowling-at-3AM-cat from 30-50 feet with water kind of steampunk gun. If there’s interest I’ll build more (think “Zazzle” but without t-shirts). I’m working on the design with cost in mind. Someone also suggested that it could also be sold as kits, which is an idea that intrigues me as well. The kit option would allow someone who wants to do the analogue of “overclocking” and turn up the PSI to above the 40psi I’m thinking of. The pressure vessels themselves are rated for 100-120psi.
Me, me, me! We want’s one, we do!
….and a spare, too!
Just think, boys and girls! Just imagine for one minute the impact – the sheer gob-smacking shock and envy a prospective employer will experience when they read ” Hobbies include: overclocking steampunk waterguns” on your resume!
If that doesn’t get you the job, nothing will!
Why – I want to hire LK right now as CEO, and I don’t even have a company!
nd turn up the PSI to above the 40psi I’m thinking of. The pressure vessels themselves are rated for 100-120psi.
Ummmmm, so how hard would it be to turn it up to say, 120?
And what’s the “k” factor? I bet it could take like 160 easy.
Since they are designed to fill a bicycle tire in one go and typically are pressurized with CO2 to 100-120 PSI and an engineer who likes himself with do a factor of safety of 1.4, 2.2, or even 4.4 (I have done on a particularly sensitive stack), I’d say your best bet is 140 psi with lots of warnings and denials of responsibility.
I haven’t looked at thread-failure limits with steel thread in red brass – 3/8-24 threads have a lot of area.
We have to be concerned about any connections, depending on how they are made (brazing vs threading vs clamping). Also, folks, we don’t want the pressure so high that you can do subcutaneous damage at short range. We’s don’t needs no law suits.
Subcoo… sobcou…sucboo… sobcutainiess damage?
I hate it when you use them big fancy words.
I plan on having some sort of plate that says that to mess with the pressure adjustment is to release the mfr from all liability and responsibility. Maybe even wire the nut that does do the adjustment so that in order to adjust the pressure one must snip the wire.
Hmmmm. Medical portable O2 bottles hold 2000 psi, and that’s typically underrated. Maybe start there for your storage vessel? Maybe incorporate some technology from the light-gas guns? Frangible diaphragms?
Or better, start with the little CO2 bottles?
Could the watergun be upgraded from cat-rated to coyote-rated for ooGcM?
Anything seen in the MRI? Or is there just a void?
I want it to be light enough to
handlepistol-whip illegal aliens without tiring one out yet bold enough to bring fear into the hearts of ruffians everywhere. It should be accessible to the working classes.Diaphragms I’d say away from, they’re temperamental.
And yes, the “little CO2″ bottles, which actually hold an amazing amount of air.
MRI needs to be read by someone then given to my doc. I am really hoping they say something other that “some calcification” in this area here and that area there. OK, but let’s fix the numbness/pain in my arms when I sneeze or the neck audibly popping in a room full of people who then look at me while I’m dealing with saline secretions from the stabbing agony.
Yep. The cries of, “Beat us, mas’sa”, and “Oh, lawdy,lawd!” as the SteamPunker Consensus-Maker(tm) is wielded with a will should be sweet to behold and be-hear. I can’t wait!
Quick Doc, a case of “lawdy-cardia”!
Should be fun times, ooGcM.
2000 psi O2 bottles? Do you want a squirt gun with Granny’s O2 bottle trailing behind on one of those little roll-around hand-truck/carriers? No chasing the kiddies with that! lol
The fittings themselves aren’t rated for even 1/16th of 2000 psi.
I plan on running the pressure vessels themselves at greater than a factor of safety of 10-ish. The idea of shrapnel isn’t one I like to contemplate.
Make a backpack to hold the bottle! Lots of opportunity for steampunk mods there. And use high-pressure air or hydraulic fittings. Put a regulator in to drop it down to your working pressure (100 psi or whatever).
Or… Use a bottle rated to 250-300 psi or so, and refill it from a standard home compressor or tire pump?
Yeah, shrapnel sucks.
Sounds like a cool project! Keep us posted! Also good luck with the MRI.
