The first of the build videos for the project Egress pressure equalization valve. The pressure equalization valve was used to vent and equalize pressure between the command module and the exterior of the spacecraft prior to fully opening the unified hatch. Build primarily of stainless steel this is a fully functional valve assembly as best as the documentation allowed. Along with many other makers I was invited to build a part for the celebration of the fiftieth anniversary of the Apollo 11 flight that put the first humans on the moon. The project was in collaboration with Adam Savage and Tested.com. I'm very proud to say that I built a piece that is in the Smithsonian Air and Space Museum on permanent display. Check out the links below for more information and 3D files to build your own hatch or valve assembly.

That is the skill and patience that makes space flight safe. I worked on space station electrical parts and I can appreciate the need for precise work and the expense of it. And the need to test every part and assembly. When it is finally build it still costs a thousand dollers per ounce just to get to low-earth orbit.

Tom, don’t ever feel like you have to cut the ‘boring’ stuff out. That’s one of my favorite aspects about your channel. Spending 5 minutes just to explain how you’ll vice a part/ indicate it, as well as you simply filing, is so tranquil to watch

@susanbarbier5053 5 лет назад

Love that you’re treating it as a REAL part. Most self described “RU-vid makers“ have the tools but not the know-how to make real parts...just because you have an “I Make” license plate doesn’t mean you make good stuff. I mean, Jesus, who else on Project Egress made custom carbide tooling to make their part!? I think the old NASA engineers would be enjoying this build if they could see it.

@rbaker1423 5 лет назад

I watched the build live. This was one of the first parts to go on, and pretty much the only piece that just went right on without any modifications. The best part was after Adam screwed it on he played with the mechanism. And with a giddy giggle, he played with it some more ... then made a comment that he loved that mechanism ... he was making a hatch of his own, but he was upset that he wouldn't have this part on his. The star of the show by far. Well done Tom.

@christurnblom4825 5 лет назад

I don't want to detract from the effort and talent put fourth in the project but in my not-so-humble opinion, it would have been awesome if those who were in charge of the project would have had more time to put this collaboration together so that all the parts could have been made from original or near to original, materials. That way, maybe they could have made a working replica. Don't get me wrong, the replica or "tribute" to the original is a really cool piece of art but having it function like the original would have been a real great icing on the cake.

Very nice job, particularly liked the radius on the mill. I was on SkyLab in early 70s which used Apollo CM to get back and forth. When we didn't have a mission on, once in awhile we would fly our girlfriend around the moon in the simulator.........worked great every time.

@Ipschnug 5 лет назад

This is, in my opinion, the best of the Project Egress parts. I think it is also a tribute to all of the manual machinists responsible for the parts in the original Apollo Program since a lot of those parts were probably manually made, one at a time, just like this!

I can imagine the 45deg hole is to have extra leverage in the unlocked position to open the valve, then move it to 90deg for "speed handle" mode.

I appreciate that the real machinist that were involved did not take the copout way and 3d print the pieces. Watching Adam savage constructing the hatch it seemed alot was 3d printed out of plastic :-( which was kind of a bummer to me. Would be super cool to build a piece that could have actually been pressed into service but with plastic parts and wooden hinges i don't think it would have made it.... sorry Jimmy D, I will admit the hinges turned out beautiful tho :-)

@valkman761 2 года назад

@Kenny Eaton You're basically talking about file format change and importing it to a tool, which converts it to g-code. Yes, you should know what you're doing but you should also know what you're doing when trying to get any quality work done from such crude formats as stl. It's never going to be any critical anyways, since you're printing parts which can't withstand anything more than weight of a plumb bob. On top of that, they have zero mechanical properties, so you're basically printing garbage.

@bcbloc02 5 лет назад

Aww Tom. If you aren't happy with the spline fit you could put release agent on the shaft, then flux the handle. Slip it together and run some solder in there and get an exact formed match. :-) Lots of tool deflection in single point broaching I suspect that made it a bit less predictable.

@valkman761 5 лет назад

I feel sorry for you Tom. This amount of work and in the final product, these "makers" had their PLA printed colorful hinges beside your part. Even DiResta's part was a disappointment. Wooden mechanism with brass plates cut with a hacksaw and scratches all over the place. No wonder they complete three projects a week.

@andyZ3500s 5 лет назад

@MakeItWithCalvin Год назад

Sadly, so many of these people go for qty > quality and it is a shame. It is not to be demeaning but it is the nature of the beast sadly. The whole concept of the project was awesome, but I think a lot of people did not fully grasp what they were doing and how it all had to work together sadly.

@unknownapprentice625 5 лет назад

Great to see that part being made, even better to know how well it was made!. I think the 45 degree handle detent may be to in crease leverage,while still being able to rotate, when getting the last bit of "gronk" out of it. The 90 degree location would be for speed and locked is, well, locked. Thanks for sharing this fine work.

@PaulSteMarie 5 лет назад

I'm guessing the 45° position is for applying some grounk to the valve, while the 90° position is four rapidly spinning it. It's a bit odd because I would expect an equalization valve to not require much travel. You just cracking in a bit to let air through.

Hi Tom, Nice project, thanks for sharing. Looking forward to the next episode. Thanks again. PS I have the same Ellis dividing head and like it. The only "improvement" I made was to add a set screw to secure the plunger handle better where it mounts into the handle... a 6x32 at about the 4 o'clock position, and it is as solid as a rock. I love it.

@bradley3549 5 лет назад

Do you regret broaching the spline from the top face? I suspect you had some deflection resulting in the bottom of the spline being tighter and resulting in a slightly loose fit on the cosmetic side.
