Steve's dental service for Delrin gears

[stevec]

As promised, here's some pics of my `dental work`
Here`s where you normally need anesthetic, I was taking mine orally.

   

Here`s the implant.

   

Mounted on a mandrel I turned off the excess.

   

The spin index set-up might be too flimsy for a metal gear but for plastic it`ll do.
I used the tailstock from my rotab to control movement outward during machining because I had set-up the spin index in the vice and I couldn`t advance the crank to keep the spindle from moving. (there`s always a way....sometimes)

   

Let`s make sure I`ve got the spacing procedure right for 6° rotation for a 60 tooth gear.

   

Here we go, new teeth appearing.

   

Finished dental "Bridge".

   

There'll prolly be a bit of a thump as the new teeth pass the mating gear compared to the old worn teeth but it should wear-in fairly quickly and at least I'll know where the thump, thump is coming from.
