Angle Master Degree Difference

[Rossy66]

I apologize if this is a stupid question but, I was wondering if anyone knows the degree difference on the angle master setting of 250mm to the middle scale of 10"?

I ask because I use 10" CBN wheels with my T8 and I am wondering if the difference between both numbers makes much of a difference in degrees also, why does the adjustable guide not point to the 10" mark?

Thanks

The Anglemaster, being a Tormek product, is calibrated to the standard 250mm Tormek grinding wheels. If the oversize difference with CBN wheels bothers you, take a millimeter reading of their diameter and make a fine sharpie line. Your guess will be close enough.

It's not stupid at all. If you play with the model here, you'll see that for a given setup (USB height set, projection distance set), the difference in angle when the stone diameter varies from 250 to 254mm is about 1 degree. So for a given position of the WM-200 on the wheel while resting on the flat of the blade, the angle read on the WM-200 should be off by the same amount.

Thanks for the info and link

As a side note, you can also get an accurate value of this offset if you use one of the many calculators available (calcapp, tormekcalc, etc.) by both changing the diameter of the wheel to 254mm *and* reducing the distance to top of the wheel by 2mm.
