The adjustable water trough introduced with the T8 is a real innovation. However, it can also be prone to introducing noise. This is preventable and easily corrected. It is explained in the new Tormek video on cambering plane blades, starting at around 20 minutes. The problem is not related to cambering or any jig. I suggest watching this video, whether or not you sharpen plane blades. Here is a link:

The problem is caused when the two forks which support the water trough get slightly bent. This can be prevented by using an inexpensive turkey baster from the grocery store to withdraw the water instead of just dumping it. Making this part of your sharpening routine should prevent the noise.

Another thing that can be an annoyance is if you overfill the reservoir by raising the mechanism when it has water in it. If you do this and water is displaced above the line it will overflow and make a mess. Raising the mechanism is only needed when the wheel has become smaller due to truing.
