Not to be cynical but how do you plan on crafting a titianium round, machining it down from round stock in a lathe yourself or are you going to send it off the be machined. The former being very difficult because of the metals inclination to work harden and form hard spots, as well as dealing with s...

there is a problem with that, i need to inject the oxygen first, because the bernzomatic was only kind enough to give me a reg that tops out at 1`5 psi. also i do have a propane meter that injects one atm's worth of propane. so i get the mix that is need for a normal hybrid. this is so we cant say a...

so todays update, i came home from work nd built the propane meter, and plumbed the oxygen in. so i really need some one to help me out with what psi of oxygen i need to inject into a inert chamber to give me 21 percent oxygen. other than that i painted a bunch of the manifold last night, but its a ...

so i was doing some thinking, and i realizer how complicated gen three terminology is going to be because we no longer have the atmosphere as a standard. So for the time being we will only consider the 4.23% propane atmosphere mixture, and the atmosphere will have the normal 21 percent oxygen. this ...

well first off thanks for the comments and support, hopefully it turns out well. In response to jimmy i do not know as an absolute fact that helium will increase the flame front propagation, but i do think the the smaller atomic radius of helium versus nitrogen will allow the gasses to " slip and sl...

alright guys, i brought this up a year or two ago on spudtech, and i have had some time lately, i just came back from the north, and bought a house, i also have an intown job that is only 40 hours a week, novel thought hey. Anyway, being a machinist and a welder by trade i decided to put my skills i...

good tosee you too bernstern, and yes it was nav 7 i was thinking about. when i say money isnt an issue i mean a can cough up a hundred or two a month to host a foum and rights to forum software, snitz is what we used before, correct. and yeah sure send me the list of everyone's aim contacts. but i ...

hey guys, i am one of the o,d members from spud tech, some of you may remember me many probably not. but what i want to say is who has the spud tech archives and what could we do to put up our own spudtech forum, build off the archives and just continue from there as if we wernt shut down. i miss th...

You "whack" it with a mechanical hammer. As your press down, it compresses a spring then a sear slips, and the hammer "whacks" the crystal. The crystal is symmetrical and as mechanical energy is transferred to the crystal the line of symmetry creates a positive side and a negative side of the crysta...

Ethyne is not a high explosive and no more so when mixed with oxygen. It's an unstable molecule so its use in a hybrid is not suitable as it decomposes at pressures near or exceeding 15 psi. So to go for a two times mixture with a chamber pressure of 14.7 psig it would more than likely decompose the...
