Now we all know who amazing of a inventor Old man McGucket is but mabye his invention "the Memory erasing gun" was influced by a familar triangle.

Remember in the of episode:"Society of the Blind Eye" in the TV used to review memories McGucket did a cameo of Bill as seen on this page http://gravityfalls.wikia.com/wiki/Bill_Cipher. In the cameo section it shows the triangle tent on McGucket did.

This can mean that Bill influenced McGucket to making the machine without McGucket know at all.He could given him the idea in a dream and gave him the basic blueprints and parts (well the ideas of what parts) to make the machine.

He did this to see if McGucket would either blast the Author with the gun or use it on himself to make sure McGucket never becomes a threat.
