Here in OKC the crank grinders dislike grinding T cranks with 1/16" radius because their grinding wheels have a smaller radius for modern cars. Several have re-radiused their wheels for T cranks, at our request, which means they need to re-establish the radius on the wheel back for modern cars. This causes a wheel's diameter to be reduced.

We're able to make arbors bigger, reduce the thickness, reduce the diameter, change the profile, and so on. Not only will this save the environment, it'll save you money as well.
