Art you are a rok star lol

Thanks Art!  I may have the gears in hand this weekend, so I'll know more when I get them and can look closely.

to be candid, given this application, if the # of teeth on the worm, tooth type (e.g., helix etc.), gear diameter, face width and bushing/collar measurements can be gathered, I think ...

very cool Art I'll be sure to keep an eye out for it
I have another post here in this forum, where I am trying to back-engineer a worm gear set, to help learn me some gear schtuff... They were shipped to me yesterday, so maybe I'll have them by the weekend...

appreciate everything you do

I read thru a bunch of hobby-machinist and PM threads, and watched some youtube vids.  I think I understand how it will work, and can figure out if it's DP or Module based contingent upon which calculations have the "cleanest" numbers, near standard pitches.

I also heard from KHK, and they ...

this post has a few pictures to help

A case split open, with a 3rd party worm/wheel replacement solution made from brass:

A view of a gear case with it?s worm, showing it?s square bore.  The square drive shaft is for the other split gear case:

A view of the plastic wheel, and a 3rd party ...

Does anyone have any tricks to measuring gears?
Are these the physical characteristics that I need to capture?

For the worm wheel:
1) Identify physical characteristics of worm gear
    a. Right handed
    b. Straight Face (does not look hobbed to me, but what do I know?)

In order to get myself tuned up for a fun but probably complicated (to me) geartrain/gearcase design for some scale helicopters, I wanted to run thru a small project to bring me more up to speed with gears/gearing etc.

As an exercise in gear metrology and then design or standard specification, I am ...

shameful resurrection of an old thread - any movement ever occur here?

There a bunch of issues for what/how this all might be accomplished, but my first step is going to examine the existing drivetrain/rotor setups, and see if I can't use some tools to determine what thrust forces are being developed.  Probably spend some time modeling the tail rotor with a tool ...

BTW, if I am posting this in the wrong forum, just move it and let me know where it lands.

Here is the gearotic model I built
