Taming the 'Universal' Tool and Cutter Grinder

摘要

Set all the work head scales to zero. Fit the slitting saw and have the setting plate on top, loosely clamp in place. Loosen the universal base plate clamp and slide it all forward until the setting plate is in contact with both sides on the grinding wheel; I find moving the spindle forward is the easiest way of achieving this. Rotate the slitting saw until a tooth lines up with the radial edge of the window. Concentrate on the point of the saw tooth especially if the gullet is angled then lock it all tight with the top clamping screw. Move the base plate away from the wheel to avoid any possible damage to it, fit and adjust the detent assembly and get it located in a convenient saw tooth gullet, photo 15. Now remove the setting plate, rotate the whole work head to get the required tooth clearance angle. Bring the saw close to the wheel and set the stop if needed to avoid catching the next tooth with the wheel; this will be easier when you have made the penguin stop which is to follow later. Switch on, add cut and grind the first tooth, keeping a constant pressure with your hand to ensure contact with the detent. Swing towards you, index and do the next one until all teeth are ground. Repeat with more cuts until all teeth are sharp, it's a very simple and quick operation.
