“The creative person wants to be a know-it-all. He wants to know about all kinds of things-ancient history, nineteenth century mathematics, current manufacturing techniques, hog futures. Because he never knows
when these ideas might come together to form a new idea. It may happen six minutes later,
or six months, or six years. But he has faith that it will happen.” — Carl Ally

Last night, in the middle of a nightmare (I was being chased around my house in my underwear by a naked ventriloquist’s dummy wearing a bandolier), I thought, what the hell does this dream mean?
Can only mean one thing: Time To Feed This Blog… Don’t you find it comforting that in my subconscious, the DSN is represented by a naked ventriloquist’s dummy wearing a bandolier?
Last week Michael and I hopped over to Idaho to supervise the assembly of the CT-17. Here is a short pictorial of our experience;
This giant multi-axis lathe is making the lead screw. This part is one of three that we made over because, well…let’s just say your tool potentate overlooked a dimension that should never have been overlooked…
For those of you familiar with machining, the CT-17 depth adjustor is off the charts difficult. Stainless steel, 72 threads per inch, and a hollow, five finger integral knob. From start to finish, this part takes about an hour to make and finish. (FYI: the going rate for CNC lathe work is anywhere from $50-$70 per hour.)


The lathe collet leaves a slight mar, so this must be removed with Scotch-Brite wheels.

After the depth adjustor is cleaned, the end is dipped in grease, and the pin nut is sandwiched between two brass thrust bearings and retained with the smallest snap ring I have ever seen. Actually, I can’t see it, but thankfully others can…

Down the line the linkages are assembled…

The body of the CT-17 is milled from solid 303 stainless steel billet. This job was under the spindle for over four months.

This image is of the area where the assembly steps were documented. It takes about half an hour to assemble, adjust and wipe off the orange Cheeto fingerprints left by Michael.

Here the assembled planes are being packed to be sent off to a facility in Washington to have the soles lapped.

We were only in Idaho for a couple of days, but the last processes are now documented and later this week the first batch of planes get their soles lapped, back to Idaho for cleaning, boxing and then shipped to our warehouse–so we are getting closer.
Since this job is so late, maybe my dream means I am the real dummy…
