Work in progress...

Super, high-quality popcorn popper ... or my name isn't Orville Reddenbacher.

Nonsense, you guys. It's the flying saucer from Close Encounters! -- ssuR

Dibbs on "Gas Pump"
Marc

Kudos to Marc... though the idea of it being an iron lung is entertaining. As far as Russ' suggestion of the Close Encounters spaceship, it must have been from the unreleased steampunk prequel...

At any rate, here it is all in one shot, at least as far as the project has progressed to date. There remains the top cap to complete along with the piping in the glass cylinder and the remainder of the valve pieces on the view-port assembly where the filler hose attaches. It is a Correct Measure Gas Pump from the late 1920s, a project I'm doing for Mobilgas (Craig) here on the forum.

Most very way cool. -- Russ

[Chuck Doan]

I agree!

[W.P. Rayner]

Thanks Craig, Chuck & Russ... I appreciate the good words. It's been a very interesting project so far. I'm going to tackle the distinctive "organ pipes" next. Thanks for posting the prototype photos Craig... these are a couple of the photos I've been using as reference shots to extrapolate the dimensions for the drawings. Interestingly enough the most problematic part to draw so far has been the side hand lever that operates the manual pump. At first glance it seems very simple, but it's tapered on all four sides, has raised edges and the openings are all tapered as well to match the profile. Took several attempts to get that right. Basically the way the thing works is, you fill the glass reservoir with 10 gallons of fuel pumping by hand with the vertical side lever, select the amount of fuel needed (from 1 - 10 gallons) using the horizontal lever in the tapered section setting it into the corresponding notch, then release the desired amount of gas to the delivery hose with a valve (yet to be drawn) outbound of the rectangular sight-glass on the side just below the reservoir. There's an "organ pipe" for each volume 1 through 10. If you needed 3 gallons, by setting the lever in the 3 gallon position, the 3 gallon pipe would line up with the distribution outlet and allow the top 3 gallons of fuel to flow down the "organ pipe." Fuel below that level would remain in the reservoir. A check valve prevents the pump from operating when the valve to the delivery hose is open, so you can't pump any more gas than what the glass reservoir will hold or continue to pump while the delivery valve is open. Fortunately I was able to find the original patent for the pump which helped a great deal in determining how the thing worked and went together.

Yes. Here are the two latest renderings from Keyshot: the first of the overall pump with the pipe organ in place, the second a detail shot of the pipe organ and glass fuel cylinder. Next step is to redraw the fuel level assemblies. The first ones drawn in Cobalt were flawed in some way as they would not import into either Inventor or Solidworks, so time to redraw them.

Heck with the model. Keep cranking out 3D drawings. Satisfactory. -- Russ

[finescalerr]

Now, now, Craig! You actually want me to be politically correct on my own forum? Go stand in the corner! -- ssuR

I am slowly working my way through a lot of threads and posts.

Paul this drawing is really sharp, make me wish I knew how to do this 3D stuff, you make it look easy but what little experience I have had with 3D drawing programs, I can see that you have been doing this stuff for quite some time. I look forward to seeing the finished drawing.

Michael

[W.P. Rayner]

Thanks Michael. Yes, I have been doing this for a while now, but am constantly learning new and better techniques with the software. With my recent switch to new 3D CAD software and a PC I still have a lot to learn, but am slowly making progress. I just finished reworking this drawing in Inventor adding all the required parametric constraints to be able to fully utilize the editing and production capabilities of the software. Now that the drawing files are properly configured it's time to draw the remaining parts.

Paul

[W.P. Rayner]

Here are a couple of new renderings, slightly different views with less dramatic lighting generated from the Inventor revised drawings and rendered in Keyshot.

Paul, it's a little after 1 a.m. PDT and your server is being very selfish about sharing your photos. Maybe you should upload them here directly from your hard drive. -- Russ

[marc_reusser]

It's 2:15 am pdt, and they look just fine to me.

I received a message from my hosting company and they were experiencing "network connectivity" problems evidently on a selection of their servers, but all is fixed and back to normal.
