LOUVERS

Nice work & planning!

Keep us posted!

...Started the fitting of the First slat louver. Had to Sand the ends to fit snug in the groove of the deck opening lip. After the rubber edge liner was removed. The first slat is fitted, the rest of the other 7 slats are cut perfect and will lay IN and between the Sides of the Deck.

Pics: Start, Closer, Closer, Still Closer, IN but NOT Down...Snapped In Down Snug in the Sails and LEVEL...Perfect!!   

...Length of ends were off by 0.125". To mate with the Vertical Angle of the Deck Sides...this is how I Correct them, on a CNC Mill.

You install your slats perfectly flat? The one I got has a slight curvature in it to make them more rigid…

Machining process question…. You are clamping the sheet under the board, and cutting with that fluted endmill?

I’m just asking to learn…. does the sheet ever try and deflect up due to the action of the cutter?

Do you run this at a pretty high RPM?

Thanks!

Rigid?? At 0.090" and Two Mounting Bars I had to put My Full weight on Them, Half a Dozen times to get them to the Slightest curvature...These Slats, NO Flexing, No Bending, I could Stand On Them!!

...No Lifting! 450 RPM for a 1.275" Diameter Cutter, Slow Feed. 8 Flutes. There is a 3/8" Thick Steel Plate under the end, 1/2" from the Edge. "The Chips tell the Story". The Tool is Razor Sharp!! 'Climb' Milling produces the Best Finish. The Cut depth was 0.1247" Done Twice at Each End to remove 0.250" on a 'Diminishing' Taper. With a 'Trial Fit' before the Second Cuts. 0.090" Thick is pretty Solid. Carbide 'V' Deburring tool will Smooth All the Sharp Edges before Painting. I would Leave them Polished But do Not want a 'Mirror' for the Sun Behind Me. I think Primer and 'Gloss Black' Just like the Lambo in the Photo Above.

I like to think that the bean counters at Ford were responsible for that “hole In the wall” deck lid design…

But as I said, it’s just what I like to think! 🤔

TOTAL REDRESS OF DESIGN:

...I figured out why the first design did not look as Fitting as the Photo of the Lambo slats, studying that Photo again!

Too Many Louvers, No Spacing!! The FLAT Slats on the Lambo Do NOT 'Butt-Up' when looking down on them. There is Spacing.

The Correction was simple for Me. Eliminate the Last Slat (H), and go to (7) Slats with a 0.625" Spacing between them, See Pic. Comes out Perfect with 7 Views of a .981" High Viewing 'Window' (On Average), Under Each Louver. Ending with Only 4.875" of Deck Showing to the Rear. And, as a Bonus...'7' Is Lucky, and gives a Louver to the Middle of the Assembly. The Entire Assembly weighs 14.7 Pounds. For Your Consideration...'Blueprints'.   

Be very, very worried when the voices in your head stop talking! That's when I think I may be in trouble. They are up to something!

...photos separate from my text (following) so they don't mess up should I have to come back and edit...

...I started the Drilling of the Slats, counter sinking for the Flat Head screws, comes last. The first photo shows a slight hint to the curvature of the twin mounting 'Beams'. The photo of the first Louver to be drilled, also shows the 'Relief' for the Antennae (Radio when the engine is off).

The Twin beams are 'Blind' Drilled and Tapped 1/4-20 NC. The Temporary Pin joining them, guarantees the stay aligned, and be Measured EXACT to Each Other, during the Process, as seen on the Monitor, accuracy is to the 0.0001" X,Y and Z.

The 'A' Drive is for the 8" Rotary Table, not being used at this Time. This Machine is a 'True' 5 Axis CNC Mill. Meaning ALL axis can be Programed to Operate Simultaneously. With-In this size Envelope, it is capable of machining most anything Imaginable, Conceivable, right up to and Including Helical/Spiral Turbine Impellers. It's all about having the Correct Cutter and have the 'Time', and skills to do the set-up and Programing!

Stay tuned for Later Assembly Photos.   

...Correction. Make that a 6" Rotary Table. And a better View of the Mounting Curvature.

…and also

Angel number 14.7, when interpreted through numerology, signifies a message about positive change, new beginnings, and a strong foundation built on inner wisdom and intuition

I first think . . Standard atmospheric pressure 14.7 psia

lots of positive things happening here

Very cool rotary table, Marlin.

We have one (manual) that we used to cut a gear to repair a lathe that had been crashed (hard!)

Not trying to take away from Marlin’s thread – but I hope he would appreciate this.

It’s a vertical rotary table, using the myriad of holes on the vertical face you can set up the precise gear configuration (based on the diameter of your blank, and the number of teeth) for specific gear you want to cut.

...Yes, I have used a 'Dividing Head' and 'Footstock', many times. Very Interesting and Precise, Mechanism!! Not many know How to use it! You're Very Skilled to Manipulate it!

I Still have One in My Shop.
