Anybody we know buy this? Morell ASI eBay

I know a sales rep with the company that gave the demonstration mentioned above. We worked together in Materials & Process Engineering at a major aircraft manufacturer until he left a couple of years ago (he's the one that prompted me to attend the training). We are still friends and keep in touch. I can contact him to see if he can help assuming somebody has access to an instrument and would be okay with the idea.

Here are some screen shots of my progress so far in CAD. Still have some work to do in getting the proper gear tooth profiles, and getting the proper fits between the various moving parts.

Here is the upper assembly.




Lower assembly front. Need to redraw the needle to better replicate the original.




And the backside of the lower unit. I have several questions here. Not clear in the picture, but there is a 3rd gear that doesn't engage anything. There is also a reference to a spring on the drawings I have, but it is not shown on those drawings. I'm thinking that the missing spring and gear are used as some sort of adjustment for the needle movement. One of the reasons I need to see inside one.




ghall, let me know if your contact can help. We might be able to get a loan of one.

You know, I don't know too much about solid works ... but I wonder if you can tune the thing in the computer to adjust the speed output on the display.
Can the program consider things like, if the base is filled with oil, can it figure out the added resistance on the spinning parts? or does the program understand how changing the tension on a spring inpacts the movement of the rest?
Solidworks is a neat program. I wonder why you don't go to the local technical school and teach this as a professor ... oh yeah, you are too busy making parts for me .... never mind!!!!

It can do the spring tension calc, seen it in one of the menus. Don't think it will do the oil resistance , but I may be wrong. Can make it animate the moving parts, but eats up a lot of computer memory.

The local school is still looking for a part time Solidworks instructor. But I have little patience for idiots, and that is usually 3/4 of any class!

OK, back to making your parts, master!

Ulpilot, Jeff,

There is no oil inside these anemometers only the two ballbearings to make it run smoothly. The rest works just like clock. Simple and ingenious.

I will email my friend on Monday. I need one of these instruments and have no problem asking for help. All he can do is say no. Is the goal to create a 100% accurate replica? Have you considered keeping only the exterior as original and using a more modern design for the internal mechanism?

As close to 100% as I can, I think it is what people expect from me.

Thought of doing it with the cups driving a generator and using an analog voltmeter marked in KPH. Hard to find a meter with close to 360 degrees of motion. And I felt it would be cheating to go that route.

That is what I would think. But the drawing I was provided show what appear to be bubbles inside the case, and a notation that this is part #2. The case has a #1 and seperate drawing showing better detail of the case as part #1. No explanation what part #2 is. So you can see where the confusion comes from.

I happen to have bought this one last week (lucky me )
I'll show you what's inside.




I first take off the rack and cups.


Then I take out the small screw wich secures the glass.


Now the glass can be taken off.

The instrument face is held by two miniscrews.
