Jan,

FYI here is the Aussie pricing from Carbatec in A$:

    T-7 (incl TT-50 & SE76) $989.00
    T-4 (plus tt-50 & SE76) $630 + $124 + $91 = $845
    Premium for T-7 = $144 (+17% compared to the T-4) for:
        Increased grinding capacity (+~100%)
        Larger motor (+66%) with 100% duty cycle (+100%)
        Increased weight (+77%)
        All steel construction + other features.

Bonjour Sheang,

I am also trying to convince myself to buy a Tormek and one issue that I couldn't see being considered is the wheel size.

The T-7 wheel is 2" wide with a diameter at start of life of 10" and at end if life is 7".
The T-4 wheel is 1 5/8" wide, starting at 8" diameter and ending at 6".

Using the formula for the volume of a cylinder as 'volume = length * pi * dia * dia / 4' we get

    T-7 starts with 157 cu" and ends at 77 cu" - so volume consumed = 157 - 77 = 80 cu".
    T-4 starts with   82 cu" and ends at 46 cu" - so volume consumed =  82 - 46 = 36 cu".

From this I conclude that there is more than twice as much useable life in the T-7 wheel compared to the T-4.

Ken might like to comment on this observation.
