One of the more challenging angles or grinds to achieve on our turning tools is getting the grind correct on a bowl gouge or spindle gouge. We have developed the Multi-Grind Jig with setup blocks to eliminate the guess work so you can focus on making the perfect bowl gouge or spindle gouge grind every time! Using this jig with any system that has a pocket v-arm attachment (not included) will make your bowl/spindle gouge sharpening experience much smoother than ever before! Typically there are 4 basic grind types (3 types of bowl gouges and 1 type for spindle gouges). The 4 basic grind types are standard, short and long for bowl gouges and fingernail grind for spindle gouges. These grinds are all simple to achieve using the Multi-Grind Jig and we show you how to do them in the included instructions With this jig and included setup blocks, you’ll be able to quickly and accurately set your tool grind projection, the correct tool angle (depending on desired grind you choose) and the proper pocket v-arm depth. Having these three variables simplified makes your setup process so much easier! Once your setup, the Multi-Grind Jig with your tool mounted makes grinding the round shape of bowl gouge very easy and very smooth when compared to free hand grinding. The natural pivoting, rolling action in provides allows you to not achieve the perfect grind, but keeps your fingers away from the wheel at the same time. The Multi-Grind is made from high quality steel. The knob is made from brass and the threads provide a smooth rotating action when the brass knob is turned. The clamp pad is covered with a non-marring PVC material to help protect your tool while grinding. The clamp opening has a v-shape base that accepts your turning tool perfectly and won’t allow your tool to accidentally roll or shift while grinding.
