School's out for summer

It's time to get moving again.

I have been printing some parts I can use.  There is a build a header kit that is sort of like lego bricks that let you make the primaries weave around everything and end up the same length.  The piecesar the same as common mandrel bends.  The kit is really expensive, like $400.  It is made from ABS... so I decided to print a set for cheap.  It took me a few tries to make ones that snap together easily, pull apart with effort, and turn with some resistance.  I had to tweak the design about 4 times and got to this:

The arrows are at every 10° and let me see quickly how these are clocked.

 Here is what is left f the spring perch.  Dead weight now

I cut through the welds:

I am sort of clumsy after being off a while.  The other day when I tried to get going again I drilled my first hole in the wrong place, second hole way too big, then exploded a cutting disk trying to cut a new piece to drill.
