Modular flip stop measuring system with a turned round base

A rotatable flip stop assembly comprising:

• a curved flip stop arm having an upper and a lower face;
• wherein the curved flip stop arm is generally rectangular;
• wherein the curved flip stop arm has a generally square void defined by a square-shaped region substantially centered within the curved flip storm arm between the upper face and the lower face thereof, bounded on all sides by the upper face and the lower face;
• a crescent opening located on the upper face of the curved flip stop arm disposed adjacent to the generally square void;
• a second crescent opening disposed on the upper face of the curved flip stop arm disposed at a distal end of the curved flip stop arm;
• a third crescent opening disposed on the upper face of the curved flip stop arm disposed at a distal end of the curved flip stop arm opposite the distal end of the second crescent opening;
• a generally rectangular adjustable bracket having a first exterior face and a second exterior face and further comprising a top end and a bottom end, wherein the bottom end of the adjustable bracket further comprises a crescent opening thereon, wherein the crescent opening of the adjustable bracket is located within the generally square void of the curved flip stop arm such that the crescent opening of the adjustable bracket is in contact with the crescent opening of the curved flip stop arm;
• and
• a bolt extending through the crescent opening of the adjustable bracket and the crescent opening of the curved flip stop arm removably securing the crescent opening of the adjustable bracket to the crescent opening of the curved flip stop, further comprising a threaded fastener received and threaded onto the bolt.
