I will not understand anything from now on but I definitely understand what you have drawn above. For once you are speaking my lingo. Thanks.
Once upon a midnight dreary, while I pondered, weak and weary,
Over many a quaint and curious volume of forgotten lore—
While I nodded, nearly napping, suddenly there came a tapping,
As of some one gently rapping, rapping at my chamber door—
"'Tis some visitor," I muttered, "tapping at my chamber door—
Only this and nothing more."
Ah, distinctly I remember it was in the bleak December;
And each separate dying ember wrought its ghost upon the floor.
Eagerly I wished the morrow;—vainly I had sought to borrow
From my books surcease of sorrow—sorrow for the lost Lenore—
For the rare and radiant maiden whom the angels name Lenore—
Nameless here for evermore.
And the silken, sad, uncertain rustling of each purple curtain
Thrilled me—filled me with fantastic terrors never felt before;
So that now, to still the beating of my heart, I stood repeating,
"'Tis some visitor entreating entrance at my chamber door—
Some late visitor entreating entrance at my chamber door;—
This it is and nothing more."
Presently my soul grew stronger; hesitating then no longer,
"Sir," said I, "or Madam, truly your forgiveness I implore;
But the fact is I was napping, and so gently you came rapping,
And so faintly you came tapping, tapping at my chamber door,
That I scarce was sure I heard you"—here I opened wide the door;—
Darkness there and nothing more.
Deep into that darkness peering, long I stood there wondering, fearing,
Doubting, dreaming dreams no mortal ever dared to dream before;
But the silence was unbroken, and the stillness gave no token,
And the only word there spoken was the whispered word, "Lenore?"
This I whispered, and an echo murmured back the word, "Lenore!"—
Merely this and nothing more.
Back into the chamber turning, all my soul within me burning,
Soon again I heard a tapping somewhat louder than before.
"Surely," said I, "surely that is something at my window lattice;
Let me see, then, what thereat is, and this mystery explore—
Let my heart be still a moment and this mystery explore;—
'Tis the wind and nothing more!"
Open here I flung the shutter, when, with many a flirt and flutter,
In there stepped a stately Raven of the saintly days of yore;
Not the least obeisance made he; not a minute stopped or stayed he;
But, with mien of lord or lady, perched above my chamber door—
Perched upon a bust of Pallas just above my chamber door—
Perched, and sat, and nothing more.
Then this ebony bird beguiling my sad fancy into smiling,
By the grave and stern decorum of the countenance it wore,
"Though thy crest be shorn and shaven, thou," I said, "art sure no craven,
Ghastly grim and ancient Raven wandering from the Nightly shore—
Tell me what thy lordly name is on the Night's Plutonian shore!"
Quoth the Raven "Nevermore."
Much I marvelled this ungainly fowl to hear discourse so plainly,
Though its answer little meaning—little relevancy bore;
For we cannot help agreeing that no living human being
Ever yet was blest with seeing bird above his chamber door—
Bird or beast upon the sculptured bust above his chamber door,
With such name as "Nevermore."
But the Raven, sitting lonely on the placid bust, spoke only
That one word, as if his soul in that one word he did outpour.
Nothing further then he uttered—not a feather then he fluttered—
Till I scarcely more than muttered "Other friends have flown before—
On the morrow he will leave me, as my hopes have flown before."
Then the bird said "Nevermore."
Startled at the stillness broken by reply so aptly spoken,
"Doubtless," said I, "what it utters is its only stock and store
Caught from some unhappy master whom unmerciful Disaster
Followed fast and followed faster till his songs one burden bore—
Till the dirges of his Hope that melancholy burden bore
Of 'Never—nevermore.'"
But the Raven still beguiling my sad fancy into smiling,
Straight I wheeled a cushioned seat in front of bird, and bust and door;
Then, upon the velvet sinking, I betook myself to linking
Fancy unto fancy, thinking what this ominous bird of yore—
What this grim, ungainly, ghastly, gaunt and ominous bird of yore
Meant in croaking "Nevermore."
This I sat engaged in guessing, but no syllable expressing
To the fowl whose fiery eyes now burned into my bosom's core;
This and more I sat divining, with my head at ease reclining
On the cushion's velvet lining that the lamp-light gloated o'er,
But whose velvet violet lining with the lamp-light gloating o'er,
She shall press, ah, nevermore!
Then, methought, the air grew denser, perfumed from an unseen censer
Swung by Seraphim whose foot-falls tinkled on the tufted floor.
"Wretch," I cried, "thy God hath lent thee—by these angels he hath sent thee
Respite—respite and nepenthe, from thy memories of Lenore;
Quaff, oh quaff this kind nepenthe and forget this lost Lenore!"
Quoth the Raven "Nevermore."
"Prophet!" said I, "thing of evil!—prophet still, if bird or devil!—
Whether Tempter sent, or whether tempest tossed thee here ashore,
Desolate yet all undaunted, on this desert land enchanted—
On this home by Horror haunted—tell me truly, I implore—
Is there—is there balm in Gilead?—tell me—tell me, I implore!"
Quoth the Raven "Nevermore."
"Prophet!" said I, "thing of evil—prophet still, if bird or devil!
By that Heaven that bends above us—by that God we both adore—
Tell this soul with sorrow laden if, within the distant Aidenn,
It shall clasp a sainted maiden whom the angels name Lenore—
Clasp a rare and radiant maiden whom the angels name Lenore."
Quoth the Raven "Nevermore."
"Be that word our sign in parting, bird or fiend!" I shrieked, upstarting—
"Get thee back into the tempest and the Night's Plutonian shore!
Leave no black plume as a token of that lie thy soul hath spoken!
Leave my loneliness unbroken!—quit the bust above my door!
Take thy beak from out my heart, and take thy form from off my door!"
Quoth the Raven "Nevermore."
And the Raven, never flitting, still is sitting, still is sitting
On the pallid bust of Pallas just above my chamber door;
And his eyes have all the seeming of a demon's that is dreaming,
And the lamp-light o'er him streaming throws his shadow on the floor;
And my soul from out that shadow that lies floating on the floor
Shall be lifted—nevermore!…Always watching! (favorite lines from Monster’s Inc)
I get it, I think. 
and I'm looking forward to it.
Wow, I didn’t realise the amount of work that will be going into this! Unreal! I’m humbled that I will be receiving such a generous gift!
I have already ordered some Efest 10440 IMRs in anticipation.
OOOH!!!
I see, the copper to make rings, the washers to make fins!
Awesome!
And following on from above, headaches, frustration, lots of naughty words, packets of bandaids. determination and skill to create what will ultimately be a work of art.
This one even required a quantum leap to graph paper from bar napkins…impressive!
The high current and associated heat pushed me to this extreme. See the op in HD2010 pills by Bucket for my other recent foray into graph paper design. For some reason a bar napkin doesn’t translate well to 3 digit accuracy on a lathe. What accurate drawing does do is let you see exactly where imagination clashes with the limitations of machine work and provides a language text that crosses continents without mistranslation. The proof is that MRsDNF understands my plan. There isn’t any lathe work on this but there were just too many tiny pieces to keep track of otherwise.
We’ll just assume that your highly odiferous friends helped with this plan anyway, would be horrible to leave Jack, Johnny, and the legendary Captain Morgan out of such equations as these!
New sketch in op.
I knew it would not last long. I’m still following thanks but making the electronic like stuff. Nup ya lost me.
Just had another look there stacked right? I couldn’t solder it together but understand it, back on track.
How do the copper/brass fins and copper rings attach ? Is a segment of the head machined away?
Intriguing…
The Master of Miniscule invented intrigue, grab your popcorn and enjoy the ride as no one re-creates a light like the Duck. 
He fits all the pieces together, layers of copper pipe and brass pipe sleeved together to perfection, sandwiches the rings and fins and solders the entire thing together into a solid piece. And if it doesn’t cooperate, he disassembles it all and redoes it till it’s perfect. Cause that’s the way Scott rolls. 
Each part of the puzzle has it’s own genius behind it, each technique and implementation a new level of genius, like playing 3D Chess with Dr. Spock. :bigsmile:
Wow, that is quite a design, very complex, very nice, watching! :-)
Now that I have a design (not set in stone, that part I still wing it), I can bore the head back halfway through the threads. There are 2 1/2 full turns and I’d like to keep ~1 1/4. That gives me about 16-17mm to play in. Then I’ll cut the head just behind the o-ring land and all those extra bits fit between the cuts and into the bore. Because of some of the geometry I’ll have to braze certain parts together so that the don’t come apart or slip when I solder others. Each fin, each wire, each set of parallel lines is a separate part(by my count 24, not including the Sinkpad or driver), all in a space about the size of a p60 pill. On the first few I made a separate pill for the led and driver that was a slip fit into the rest. Because of the higher drive current on this one (1.5A on high) I wanted to try a one piece design(albeit soldered) but with more larger fins. I also wanted to retain access to the driver which is why it’s threaded into the back half of the head. The brass male threads at the driver end will be brazed to the first brass fin but the female threads there and the male bezel threads will be epoxied with JB weld. Getting sketches done and my brain wrapped around it to the point where I can see the process in my minds eye takes time and I’ve learned from unfinished projects not to start until I can do that. I can’t always do that but I much prefer it that way. Today I start cutting so check back for updates.
Scrolling through the op in edit mode is a pain, what did you all think of my use of links for updates in the last build?
Are you using advanced input format?
I’m using the iPhone input format. Keypad takes up 2/3 of the screen and on a long post the text doesn’t all fit in the box and I have to navigate out of the box without having the cursor move to get to the controls and input pics, links, paragraphs, etc. after a few edits in the op it’s much easier to put updates at the current end of the thread and put a link at the top of the op. Then, no matter how many posts follow the stages of the build can be tracked. Since there’s just descriptive explainations in Post 16 I might not link that or if I did just put”blah, blah, blah” in the link text box. Just for you I also edit the thread title with each new link added.
I hate using a phone to even read threads let alone try and post with one. What you did last time from memory works fine by me. Just remember lots of pictures and waffle.
I know a lot of people do that, but to me it’s just nuts. I don’t have a smart phone though so that probably explains it. I can’t imagine reading this forum and looking at the pics on anything less than my 24” monitor. lol. Heck, I’ve had bride and groom try to pick their pictures out on smart phones, baffles me.
However you do it, keep it coming. And make the pictures bigger if you will, I just ordered an M1 and need to see your shot’s closer so I can copy you…
