oil stone case.

today we got given some to scale drwaing of how to make an oil stonae case we had to use these drawings to make our own oil stone case. we were given 2 peices of d4s timber at 300mm long. d4s= dressed 4 sides. we had to mark out the oil stone dimentions onto the centure of the timber accuratly. once we had it marked onto the wood  i chiseled around the edge about 3mm inside the my mark to keep the edge from chipping off. once i had it near 13mm deep i used grounding router to even of the bottom of it. i then marked out the top of the case the same as the bottom and chiseled it out to the same 13mm deep. the bottom had to be a tight fit but the lid had to be 1mm loose so that the stone couldnt fall out but the lid was loose enough to get it off. we i ten marked out the lid an planed each sie an end to give a 45 degree pitch on each side at end. the bottom also had to have feet chiesled to stable it on un even surfaces. i marked 35mm in from each end of te timber an then marked the centure of the timber an cut down 5mm into the ceture line. i then drew a line from the 35mm line to the 5m cut then chiseled it out.
