4 February 2020, Pulsing and 3D Printing


The campak now includes 5 cams, with the most recent being the cam that turns on the pulsing.  One of the features of this automata will be the convict ‘shaking’ while he is being electrocuted.  I’ve played with the idea in my mind for months and have just recently built two versions of the pulsing mechanism, the second of which seems to be what I want.

I attended a Miniature Show in Del Mar this past weekend and found a doll seamstress who is willing to sew the outfits for both the convict and the guard.  Good news.  I was sort of dreading doing the clothing myself.

I’ve immersed myself into 3D Printer prepurchase activity.  I looked at 3D printing three or four years ago and was not compelled to move into the field.  3D printing has done a lot of maturation in the last few years and I now feel that it is time.  I had been lusting for a miniature lathe and mill.  When I carefully consider what I would be creating I find that a 3D printer is better suited to my needs.

Critical to 3D printing are the ‘filaments’ that are used.  I was pleased to note that in addition to purchasing strong stable filament (for gears, pulleys, etc.) I can also obtain filament that is wood, copper, brass, aluminum, and bronze based.  These last specialty filaments all contain PLA also…none of them are pure material.  But for my purposes, I feel that they will be useful.  

A primary use for me will be biped printing.  The bipeds are 11″ or so tall so I need a printer capable of that height.  At this time I’m considering a delta style printer, a FLSUN QQ S,  It looks like an interesting and capable printer that is receiving good reviews.  So for example, instead of needing to copper leaf my bipeds, I should be able to simply print them using the copper filament.

As I do this research I continue to be thankful for the Internet and for all of the information that is available to me (us).  What would have been so difficult that I perhaps would not have done it is now relatively easy.  One of the things that I love is the fact that I can access the writing of so many people…so many thoughts and opinions.  We are very rich right now.

Five of the six cams have been cut.
