Speedo repair-Tufnol gear replacement

Post by Declan_Burns »

I have had some test pieces made in brass which have just arrived and the quality is quite good. These were always difficult to source.

Hi Declan

Are these 25T versions...... save me trying to count?

The originals were Tufnol or Nylon?

I've got the luxury of looking on a large computer screen. :wink: They're 25 teeth.

Taupe,
I confirm the ones in the photo are 25 teeth. They were used on both Jaeger and Smiths speedos. Depending on the marque and the calibration there were 20, 25 or 32 teeth. They are all available.
