1982 Matsuura MC-500v Retrofit

Andy you got me thinking about this....

I checked my steel rack and I used 1018 for the gear and not 4140. I was going to bu the 4140 piece I had was not large enough. So I grabbed the 1018 stock instead.

Updated my posts to reflect. Thanks for bringing up the topic of material.

Doing a bit more Googling, there isn't enough Chromium in 4140 to make it a stainless anyway.
(I am not too familiar with the US steel standards)

Correct... It is pretty far off from being stainless. If 4140 had 10-12x more chromium it would stainless. Either way it would have worked fine for this gear, but I ended up using 1018 anyway so all is good.

Working on setting up a sensor mounting system now. Kinda unsure on how to align the two sensors on the teeth. I am thinking that one sensor should be centered on a root and the other sensor needs to be on the leading edge of another tooth. Never done one of these before so I am learning about the gear sensors as I go.

As long as one sensor is on an edge (any edge) while the other is half-way between two edges it will work. Make one mount slightly slottted is possible.

I will give it a go after I design a mount for the sensors. I will post my results.

Thanks

Here is one I did. Drilled holes and epoxy.

Kapton tape to keep the leads off the base plate.
