Wow no kidding, thats weird.

Already the part count on the radiators is up over 200!

It still sort of works if you just click on the first thumbnail and then use the arrow keys to flip through the photos.

Now that I have a plan for the panels, I'm starting to think about those "riffeln" again. I accept that there's just no way at this scale to replicated them physically, but I still have the option of trying to create an impression of them somehow. One approach is with a marker pen. I've tested this and it works from a distance, similarly to the fuselage nails which did with a permanent marker. Up close the effect to too strong (like stage make-up) but from a foot or further away, the impression is good. Probably a better result would be to paint lines on with a slightly darker tone of "steel." But I don't have a clue how I'd manage that.

well looking at the original photo and back to your card Hazet radiator mockup,.. its really very convincing, I'd be very pleased with a result like that!

Mein Duff

That's an incredible amount of detailing to be done on those radiators...we can finally see with this close up photo what lies ahead...but it sure will look awesome when it's done.

Hej Don,
In erster Linie bist  Du ein Künstler..... und dann ein großariger Entertainer!
Ich freue mich immer....hier zu lesen!!

Thanks, Tom. I try to have fun!

The problem with the CA-saturated cardboard is that white glue doesn't bond well. I may have to resort to (thinned?) epoxy.

abufletcher

Slowly all the experiments and trials are coming together and starting to look like a radiator. I'm torn between two approaches: 1) replicate or 2) simulate. The replicate approach would involve producing individual panels with their individual pipe sections and then stringing them together as on the original using the 1.2mm rods (and some inserts). With the simulate approach I'd just slip the flanges on over one solid length of pipe to create the impression of separate segments. Of course I like the replicate idea better. But it does seem a bit more involved.

Other question are how should I attach the panels to the tubing and how to attach the support brackets to the pipes.

abufletcher

By the way, the flanges on the individual panel sections are indeed a thin sheet metal type. But the flanges on the pipe fittings are the more typical fat plumbing flanges. Maybe I need to cut these out of GFR material.

My problem is that I keep looking for "the easy part," but I think when you commit to doing this sort of detailing, there just aren't any easy steps anymore. Oh, how I would love just to CA the panels to the tubing. And, oh, to just glue the whole thing to the fuselage!

BTW, mods, the "smileys" don't work.

abufletcher

Here's one way to mount the radiator. I'd need about 24 of these.

abufletcher

Well, now I know I CAN, but do I WANT to???

abufletcher

There's just no end to these radiators...[]

Mein Duff

Also to add to your perplexity is that the radiator panels are cocked at an angle to the wind correct?[X(]

Don you have a PM

The panels are angled about 10Ëš relative to the pipes and the whole radiator is sloped on the side of the fuse...so that's 3 different lengths for the brackets. Here are some of the parts. I just keep wondering again and again whether there isn't some alternate "easy" way to get moor less the same effect. And while I wondering I just keep pushing forward with this plan. It reminds me of the old riddle: How far can you run into a forest?















Halfway. After that you're running OUT of a forest.

abufletcher

Let's see, that's...

60 x corrugated paper strips for the panels
40 x 5mm aluminum pipe sections for the panels
64 x flanges from 0.3mm lithoplate
32 x flanges from 2mm GFR sheet
24 x 5mm brass tube sections with silver soldered support tab
16 x assorted length support brackets
8(?) x assorted curved 5mm aluminum rod pieces

abufletcher

So what would you more sane modelers do, when faced with this building task?

abufletcher

Bit by bit a plan comes to mind. Panels onto tube with pin through center and pin hole in tube. That holds it in place. Then it's carefully epoxied to the tube. Next, that flanges aren't actually glued to the panel tube ends. Rather the flanges are placed on a short section of 4mm tube and then sandwiched between two pieces of the 5mm tube. This also serves to hold the panels together (the stainless steel rods being only cosmetic).

This plan is still a LOT of work. But at least it minimizes the critical work, where fractions of a millimeter count.

Note: Once one aluminum tube "binds" with another aluminum tube, no amount of force is going to pull them apart! I'm glad I discovered this by accident now rather than at some critical point in the future.

Don,

When you get to the point of choosing the colors of the radiators, this might be of interest:

Well, we know from the Woodman articles (based on the 1915 report in Flight) that the H.Z. radiators were stamped from steel sheet, not brass. But you can definitely see examples that have been painted white (or light blue) like the rest of the aircraft, so we have evidence that they were at least sometimes painted. They examples that I've seen against a dark stained fuselage appear quite bright so I'm assume either "bare metal" or a metal-colored paint. I tried some Metalizer Steel but it looks a bit too grey to me.

Mein Duff

Just think about that nice "Scale Merrit Badge" awaiting you after the radiators are done!![>:]

A "Scale Merrit Badge" and a bottle of 100 year old scotch .
Just to relax him be for the maiden flight.

Hey Don,

Where would I find the Woodman articles (based on the 1915 report in Flight) that refer to the construction of the Hazet Radiator?
