I just bought a Rolleiflex 3.5 Tessar yesterday and the only problem is that there is a notch that resets the film counter and it has worn down so the counter is not reset between each roll. I want to try and sauter a little silver on it so it triggers the counter. Is it possible for anyone to maybe post a photo of the piece so I know roughly how to large to make it? Or if anyone has any other ideas that'd be great too. Thanks!

You might try joining the mail list called rollei_list. There are lots of very knowledgeable Rollei people there.

I am thinking that the material is aluminum. You will not be able to solder to aluminum. It is also probably why it wore down - it is very soft.
If it were mine, I might consider removing the entire piece, and attach a new piece, perhaps made out of a stronger material.

I'm not at all sure but I think the Rollei has the usual system - someone will correct me (soon I hope) if I'm wrong.
Do you mean that the edge of the back door is not pressing the lever to start the counter - or something different?
If this is what you mean the usual reason is that the edge of the door is slightly bent outwards near the lever & needs straightening. If that is the case you also have to keep the light trap effective.
Don't do anything until you're certain though!
If a new piece does need to be fitted adhesive may be better for this than solder whatever the metal.

I would look into David's solution first. Excessive wear to the extend that the counter is not reset is unusual. The notch being "missed" by the intended part of the backdoor has happened before and this can be carefully adjusted. Less than 1 mm might do the trick.

And check if the back is not so deformed that it fails to properly push down the tab before you do anything drastic. The backs are surprisingly soft and can be pushed back into shape with a bit of care.
