Making a pantograph
#5
Clamp the bracket to a Popsicle stick and solder it together.
Try to get the solder to flow into all the gaps.
I found that adding a piece of wire as a filler and lots of flux helps.
   

Use a small file to remove the excess solder.
   

Form the lower cross braces as shown using jig #5 as a pattern.
   

The lower arm assembly will be fabricated in jig #5 by inserting two peices of wire through the arms fabricated earlier.
The equalizer lever of the arm on the left will be inserted into the hole in the jig.
The equalizer lever of the arm on the right will be pointing upward.
Use pins to hold the assembly in position.
   

Clamp the assembly, apply flux to the two arms where the bottom wire is inserted and touch it with a tinned soldering iron.
