I was talking with cooper off line, asking about double radius gouging, which I have not done, having spent most of my career chasing the perfect 45 - 60 - 45 gouge.
Now that I am making a machine capable of double radius gouging, I think I need to learn lots more than I know now and we decided to put the conversation on the BBoard to get broader input.
Cooper summarized our conversation on the RDG Gouger thread as follows:
1. Most machines have different radius blades available
2. The big difference in feeling from one gouge to another is the grind angle and the curvature that it achieves from the grind angle.
3. These different curvatures cut away different amounts of cane in different areas which produce "different gouges"
4. The rest of the differences between gouging machines are materials, design, etc. But the most important is finding a good combination of radius with grind angle to produce a good curvature.
I agree.
What I am interested in is probably mostly anecdotal, but if enough people agree, we might be approaching (glowing in the sky) Truth.
My first question: If you are going to gouge off the center line (to get the double radius) then you will need a smaller diameter blade than the size-on-size blade of single radius gouging, in order to keep your sidewall thickness.
The smaller the blade, the larger the internal 'spine' produced if you maintain the same sidewall thickness. Is there a 'sweet spot'? What is it?
