And I found one more today at a local electronics and industrial supply place for super cheap.
Would anyone on this page be willing to do a BTTF parts exchange?
It seems like we are all individually re-inventing the wheel. It might make more sense for each of us to specialize in a few different parts, and then trade (or pay for) with other builders.
I think that it would be a wonderful idea if we could make it work.
( I can build tfc switches with my eyes closed now. ( I realize that it is probably the easiest think to build)
Just a thought....

I was recently watching the OUTATIME documentary and refering to what you had said about the positions of the oops holes. In my looking at these details I have noticed a few things that are of interest:
- The rear most (center) heatsink seems to have only two vertically aligned screws instead of three as seen on the Jameco heat sinks.
- The heat sinks seem to be very slightly different from each other and slightly offset from each other (not perfectly aligned around the 15" core base equator).
- What size are the screws that hold the heat sinks to the core base?
The spacing is not perfectly even since the heat sinks were all spaced by hand and I'm sure there was some drill bit wandering in addition to measurements not being plotted out exactly perfect.
The heat sink mounting screws are button head cap screws, either size #10 or #12. I haven't gotten a chance yet to load up the CAD model to check those other holes you asked about, but I can check the screws too.
