Are you going to leave the ends of those square? I would think a radius would be better.

Not square, those were just scraps to show the layered look I'm going for to match the engine guard angle.
I'll post up a rendering shortly of the fin shape.

Edit: Here's the top fin.

The excess material is still shown. I'm thinking of using 3/16" thick alum and cutting 5 each 3/16" slots were the original Honda small "fins" were.
Then I can plug weld them from the back side of the cover. I would weld a full bead across the top fin and mill it down with a ball-end endmill.
Will probably also weld each end of the fin on the outside to blend it into the wrap around Honda fin if that makes sense.

Cool idea of the coolings fins, I was planning on doing the same:
Only I was planning on using heat sinks

Those are very cool! action1
The style I remember. Wonder how many were made.

I'm just now taking the first fin off the mill.
Update shortly.

Here's the trial slot in for the top fin...
(that ugly ground down weld will be covered and this is still just a prototype)

And the profiled fin...

I rounded the end of the fin instead of squaring out the end of the slot.
(simply because that's easier, and I'm lazy!)
valve cover fins 019.jpg
Here's the top fin in place, not sure if I'm going to go with one this deep.
Will need to see how it looks on the bike.

Also, I think I'll make the 3 middle fins out of 1/8" thick stock to match the Honda fins better.

Now, off to melt some aluminum! :flamer

I'll not surface cut down the fins as it left the center of the cover paper thin.
But I think this will work, but keep in mind, I'm still "Winging" it! lolol lolol lolol
Here's 1/2 of the down and dirty trial plug weld on the inside that will hold the fins and keep the cover oil tight.

This is the ball end mill that I'll use to round off the weld on the upper length of the top fin to blend it into the cover.

And here's my gross attempt to merdge the fin into the Honda fins.

Calling all (or any) mold makers out there......
Can you give me any hints on how to merdge or blend in the fins at the end?
PM me, I promise I won't tell. :-D

I remember hearing the later covers were thicker. Not sure by how much though. Here is one reference..

http://www.motoraction.com/story/index.htm
1977 saw the first tentative model changes based on customer feedback to Honda (hands up all those who can remember filling out those early questionnaires at rallies) and the Goldwing got higher handlebars with neoprene grips, dual contoured saddle and chromed heat shields on the header pipes. Chromed upper engine mounting brackets were a nice touch. More importantly, the steering head bearings were now tapered rollers instead of quick-wear & seize ball types. Front & rear engine and rocker covers were now thicker and this was designed to reduce noise, but no-one really noticed. The fuel tank had an internal coating applied to prevent rust.

Thanks Ron!
I'll check a few other covers I have.
Might be ok with any as I milled down that one thinking I'd need to have a flat surface, but with individual slots cut and plug welding, I think any will work.

You said something in an earlier post about doing it an easier way because you were lazy. This definitely is not the project of a lazy man. I am enjoying following along.
Bikes at present:
80 GL1100 Interstate: Now a Cafe Racer called DRAGON WING.
75 XL 250 just for fun
83 XL 600r with a 2004 XR650L engine
And a couple of older BMW GS adventure bikes (keep hoping for an adventure!)
A fleet of parts bikes awaiting resuscitation or customization or abandonment :IDTS:

If all the fins were welded in, you could then shape the joints using the roller end of a belt sander?

Haven't done much with this, but I did have an idea that will save me a lot of finishing time.
Instead of welding the length of the top fin, then ball milling it down and finally blending it in,
I'll just powder coat 'em!
Here's a cover that I had coated probably 15 years ago.
Aluminum color power with a clearcoat...
valve cover fins 027.jpg
I figured that if I could get the powder thick enough or maybe go with two coats, it would fill the slight gap between the slot and the fin.
I was just shootin' some other parts flat black and gave it a go.

Just sprayed...

Came out great in a single heavy coat. dancr
valve cover fins 030.jpg
Here's a pic using a flashlight to highlight the angle.
valve cover fins 029.jpg
I will need to overcome what's called the "Faraday cage effect" to be able to coat in between the fins, but I'll preheat the cover first and shoot those areas with a small tube attached the the gun.
Maybe coat them with gold powder, then I'd really have gold wings! shakehands lolol

I could be wrong but I dont think powdercoating will work in the longrun
It occurs to me that over time vibration could cause small cracks that will allow leaks.

Good point.
The powder coating won't be the "seal" as I will weld the back side of all fins inside the cover.

Here's how I very precisely measured the angle needed to match the engine "guard". shakehands

And the cut fins before removing from the tabs...
