17.モンキーのエンジンを4気筒にする（初めての砂型鋳造）17. Make the Monkey engine 4-cylinder (first sand casting)

After repairing the CNC, I returned to the 4-cylinder engine! !!
This time is the cylinder casting that I have been looking forward to for a long time.
I used to do lost PLA casting with plaster, but I enjoyed it because it was my first time to use sand mold.
