Tenshodo 14:1 Worm and Wheel.

I needed a Tenshodo type 14:1 worm and wheel for the current project I'm working on. The Tenshodo's were about the right size and would probably do the job, but a preference for metal gears prompted this sub project. The one thing that this blog demonstrates besides novice gear making, is how much time can be spent making side tracked components before work can begin on the job in hand. Now that the gears are complete, changes have been made in the main project that may render these gears as unrequired, we will see.

A very informative and well illustrated guide. You really do need metal gears for a Tenshodo as the plastic ones do tend to split.

Why was the hole in the axle cut with a burr rather than a drill bit?

Very impressive engineering. 

 

The shadowgraph takes me back, I remember an optical instrument maker I used to work for using a similar device to inspect small components for accuracy.

Hi, For no other reason than I prefer to use a dental bur on that particular lathe when drilling small diameter stock, it leaves a small concave without to much preasure.  I still use centre drill's, but when drilling 2.0mm dia brass they tend to get in the way, I can't see what's going on.

That shadowgraph must be quite rare, lets face it, who else would want one, only used it a handful of times.

A company I worked for had a Shadowgraph  in about 1964 which resided in the "Tool Room" where special tools were produced for the large-ish number of lathes and presses in the works. I saw it being demonstrated to a group of apprentices but never saw it used "In anger"
