Step 8: Welding the 'bell'
This iron piece wil serve as bottom in the pipe head. You need someting to hold the tobacco in place, no?
The bell is hold in place by the piece of thread in the head and should not be welded within the head. This will allow you to clean the head properly after use in case of a non-iron-nor-glue-build pipe.
Weld the reduction and the small male cap together.
Cut the upper part of the reduction.
Drill a hole rom the iside in the center of the bell, not too deep!
Drill a hole from the outside to become an 'L'-shaped hole.
Ready it is!
