Problem Statement
Improve current core control that was built following these instructables

Testing


It takes two people to run the core control. One person holds the cables carrying cold water, the other person puts their hand in the core control (some part of the wrist must be bigger than the opening) and uses the other hand to draw a vaccum with the brake bleeder. It does work.

Materials
These materials were ordered:
 * 4 in. x 10 ft. PVC Sch. 40 DWV Plain End Pipe
 * Flexiable PVC Coupling
 * grommet assortment
 * wrist seal

Wrist Seal

 * The problem is that thin people stick their arms in it and can not create a vacuum. A mechanism to seal the wrist is needed.


 * The original core control unit had an iris that was twisted to dig into the skin and create a seal.


 * The 3/2013 core control unit has a consumable glove that periodically has to be thrown away and a new one purchased. An attempt was made to purchase this glove, but Avacor will not sell unless a complete unit is purchased.

So the wrist seal or gasket was ordered. (see above)

Next Steps

 * Develop test protocol
 * See if the wrist gasket purchased will work for those with smaller arms
 * Mount and seal the pump so that one person can operate the whole thing
 * Develop two hand solution
