I have found a source for gears that just may be useful for those builders requiring them constructing wreckers ,etc. My lovely and very understanding wife has COPD and one of her medications is an Anoro Elipta inhaler. As any scratch builder would I took one look at the delivery device for this daily dose and found some very interesting uses for it. After de-constructing one of these for using the shape of the outer pieces for body profile sections for the antique travel trailers I like to build ,I found the gears inside. Some require trimming before use but that is no problem.
Here's what you'll find inside....11 total gears as follows.
2 that are.07" thick, x .70" wide with 21 teeth
2 that are .07" thick x .48"wide with 16 teeth
3 that are .07" thick x ..60" wide with 19 teeth
1 that is .062" thick x .58 wide with 21 teeth
1 that is.062" thick x .60" wide with 20 teeth
1 that is .70" thick x .58" wide with 20 teeth
and one that is 1.15: wide x .060" thick with 39 teeth ,This one has a .84" opening center opening and is on the back side of the daily dose number counter dial.
If you know someone that uses this medication you might ask them to save the empty dispensers for you. This is a prescription only medication and very expensive @! about $ 400.00 for one month's doses' hope this helps you "gear heads" out a little.
