I have an old 6" delta jointer that uses the pork chop style jointer guard. However, I don't have the jointer guard, so I would like to fabricate one but again I don't have one to start with. Does someone have some specifcs about this item that they could share? Like how it works? also if someone could share the dimensions of one that they have but best of all would be if someone could trace the outline and include dimensions. This way I could get one fabricated and have it be pretty close to accurate.
