A stop system may include: a first member; a second member movable with respect to the first member, the first and second members being different parts of a common machine; a body including a boss defining a hole; a base plate at least one of: attached to and part of, the body on the side of the bod

A stop system may include: a first member; a second member movable with respect to the first member, the first and second members being different parts of a common machine; a body including a boss defining a hole; a base plate at least one of: attached to and part of, the body on the side of the body opposite of the boss, the body and base plate forming a shoe; and a fastener extending through the hole in the boss thereby pivotally attaching the body to one of the first and second member. A method of providing a stop for stopping a thumb against a stick is also described.

1. A stop system for a machine having a thumb and stick comprising; a first member being either the thumb or stick;a second member being the other of the thumb or stick than the first member, the second member movable with respect to the first member, the first and second members being different parts of a common machine;a first body including a first boss defining a first hole;a base plate defining a substantially flat surface, the base plate being at least one of: attached to and part of, the first body on a side of the first body opposite of the first boss, the first body and the base plate forming a first shoe; anda fastener extending through the first hole in the first boss thereby pivotally attaching the first body to one of the first member and the second member wherein the fastener is dimensioned and made of a material selected to cause the fastener to shear before the base plate causes gouges in the member to which the first body is not attached when the base plate and the member to which the first body is not attached, come into hard contact; anda substantially flat contact surface located on the other of the first member and the second member than the first body, the substantially flat contact surface located such that when the first and second members are in proximity with each other, the base plate contacts the substantially flat contact surface. 2. The stop system of claim 1, further comprising: a second boss located on a second body defining a second hole substantially coaxial with the first hole in the first boss; andwherein the base plate connects the first body and the second body and the fastener extends through the first hole in the first boss and the second hole and a hole in either of the first and second members. 3. The stop system of claim 2, further comprising a second shoe located proximal to the first shoe and the second shoe is located and configured to contact a contact surface. 4. The stop system of claim 2, wherein the first body and the second body are made of a single piece of folded metal. 5. The stop system of claim 1, wherein the first body pivots about the fastener with respect to the member to which the first body is attached. 6. The stop system of claim 1, wherein the base plate is attached to the first body. 7. The stop system of claim 6, wherein the base plate defines at least one hole and the first body defines at least one protrusion, wherein the at least one hole and the at least one protrusion are dimensioned to allow the protrusion to extend at least partially in the hole, wherein the protrusion is spot welded to the base plate in the at least one hole in the base plate. 8. The stop system of claim 1, wherein the substantially flat contact surface is an outer surface of either the first or second member. 9. The stop system of claim 1, wherein the substantially flat contact surface is on a plate attached to a member other than the member to which the first body is attached. 10. The stop system of claim 1, wherein the first member is a thumb and the second member is a stick. 11. The stop system of claim 1, further comprising a hole in one of the members through which the fastener extends along with the first hole in the first boss and the hole in one of the members and the first hole in the first boss are slightly differently sized from each other thereby configuring the base plate to both pivot and slide when the base plate contacts the member to which the first body is not attached. 12. The stop system of claim 1, wherein the fastener is a shear pin having material and dimensions selected to cause the shear pin to shear before the base plate causes gouges in the member to which the first body is not attached when the base plate and the member to which the first body is not attached, come into hard contact. 13. A stop system for a machine having a thumb and stick comprising; a first member being either the thumb or stick;a second member being the other of the thumb or stick than the first member, the second member movable with respect to the first member, the first and second members being different parts of a common machine;a pivoting means for abutting defining a substantially flat abutting surface, the pivoting means attached to one of the first member and the second member; anda contact surface being substantially flat and located on a member other than the one of the first and second members attached to the pivoting means for abutting, the contact surface located such that when the first and second members are in contact with each other, the pivoting means for abutting contacts the contact surface,wherein the pivoting means for abutting is attached via a fastener made of a material and dimensioned to cause the fastener to shear before the abutting surface causes gouges in the contact surface when the abutting surface and the contact surface come into hard contact.
