The woodturning class is the first online class to actually use one of the diamond wheels. I found the discussion comparing the diamond and traditional grinding wheels the most comprehensive and informative that Tormek has presented. To its credit, Tormek has never used "diamonds are forever" implications to sell diamond wheels. Yes, diamond wheels are long lasting; however, the class emphasized the practical benefits of diamond wheels. Diamond wheels cut fast and their diameter remains constant. Related to the constant diameter, no truing is required. In my opinion, truing is not a big deal; although not having to adjust set up to compensate for diameter changes is a definite plus, especially when switching between grinding wheels.
Much of my exploring beyond the SG-250 has been a quest for a coarser grinding wheel. The class made me more aware of the benefits of the DF-250 600 grit wheel. Most of the time we sharpen rather than reshape. I appreciate the class not being a marketing op trying to sell all three grits. I was also pleased to see flat sharpening on the side of the wheel mentioned as a possibility rather than another marketing opportunity.
The class gave me a understanding of the possibilities of the SVD-186R gouge jig. I did not realize that the fingernail shape can be controlled by the amount of arc in swinging the blade. I have always thought the TTS-100 and SVD-186R are Tormek's most advanced, versatile combination. I now realize that it is even more versatile than I imagined. I look forward to studying it more intensely.
I appreciate that the comparison of the SVD-186 and SVD-186R was honest and made no attempt to up sell the newer model where it offered no practical benefit.
I especially like practical tips. Using the TTS-100 to scribe a pencil or marker line square on the grinding wheel is very useful with skews.
The online class did not answer my questions. It did increase my understanding and will be beneficial in generating future questions. It was well worth my time, and I will enjoy studying it several more times.
