Starting the Jig for Aligning the Frame Tubes

Here is the start of the jig I will use to align the 2 frame tubes for welding. Today we deal with the cross tube.


Install a bolt in each end plate as a reference point.




Drill some temporary mounting holes


Screw on a 2x2 to the end plate.




Align the tube even with the bottom of a piece of melamine. the hole saw in the middle approximates where the next jig piece goes so it will line up with the pre-drilled holes

Nail the 2x2s in place.




The cross tube is now flat and level to the bottom edge of the melamine. Part one of the jig is now finished!
