adapting for variable needle size
ride height of needle
- the geared and non-geared plates sandwhich the butt of the needles to maintain control of the needles height
- before the needle is sent up it is breifly lowered slightly to pull tension on surrounding fabric.
- the lowest point of the groove on part CKp3.scad that the butt of the needle rides should be at this lowered position
- also the the length of the needle below the butt needs to have room to be lowered without hitting the top of the CKp3 base
- in general:
- the sandwich needs to be raised higher if the needle is longer below the butt
- the butt groove needs to be raised as well
- the design could be changed to put holes in the base of CKp3 and the main table plate to allow the bottom of the needle to move freely downward
- the butt groove would could start lower
- could move all of CKp3's mounting screws outside of the circle.
- use a style of claws similar to the inverse of CKp4 to hold up CKp1 from the base
bent tail
- some standard needles feature a design where the area section below the butt is bent up to meet the butt.
- this effectively doubles the "Y" dimension for the "B" dimension
mountain
- wall of CKp3 might need to be made thicker to counter the torsional forces on the needle butt while passing through the mountain
- perhaps CKp3 wall thickness = ((H-Y)/2)
