Making a pinion for my Buffalo 14" drill press

The picture below shows the pinion from the belt tightening arm on the drill press.

I would like to make a new one with a bigger knob on it. That way it will be easier to tighten the drive belt.

The pinion shaft is 0.750" in diameter with 7 teeth and a pitch of 12.

I have the proper equipment to cut gears but I can't figure out which Involute Cutter I need to cut the teeth in the new shaft. In fact I'm not sure such a cutter exists. All the charts I reviewed don't list a cutter for less than 12 teeth.

How would you make the teeth in the new shaft?

Why not just turn down the knob end and attach (press or Loctite) a larger knob assuming the splines are OK.

The splines are fine. I just don't like altering existing / functioning parts that I can't replace if I damage them.
