10 forum posts	I have just purchased (from Ebay) a Martek professional drill grinding jig. From one of our Society members I obtained a photocopy of the instruction leaflet. However, I follow the instructions, I always seem to get a negative (i.e. reversed) clearance angle. Excellent for creating heat, but not for cutting metal! Any ideas on where I'm going wrong?

I've taken it to pieces and studied it till I'm sick of the thing and it still doesn't work. so if anyone has an answer I'm all ears as well. Roy
