Hi Chuck, Great stuff every update

Thanks, gents! I certainly feel like I'm in good company here! :laugh:

A friend scanned this pic for me- the clearest shot of the props yet. I think I can fake it from here- anything to add, Maxitrone?

I finally see the addition to the props:

Here is a Jumo 213E engine. The props have the fly weights on them. These are a mechanical pitch control which depending on the speed, throttle position etc would increase decrease prop pitch so you wouldnt get a runaway prop. It also took a bit of the load off of the pilot. The last aircraft I worked on with mechanical pitch control was the CP 121 Tracker. Your pic looks like there was a fairing over them.

Here is an link you might find interesting also http://www.enginehistory.org/German/BMW/BMW801.pdf
Other than that I cant find anything.

Now here's a man with THE PLAN . Thanks Saul. Perfect Jame ! Been scratching my head on this one for a few days now.

Cheers, Christian B)

Hurray- great info, gents! :yipee

Another couple of pics have come my way-

Again, these don't look the same- but show how they bolt on. I'll guesstimate the fairing and it's angle using the MkI, or if next week, the MkII eyeball.

Many thanks!

Chuk,
The pictures you posted of the Ju 388 propellers with the external external bolt-on pitch weights look to be the exact same type of pitch weights used on some of the late production Fw 190A's with metal propeller blades.

On page 9 in the first volume of Eagle Editions ''Wings of the Black Cross'' series there is a nice photograph of a captured Fw 190 in Germany that clearly shows the pitch weights. As to why some German aircraft with metal propellers had the pitch weights and others did not I have no idea...possibly lower quality metal propellers were being manufactured at that stage of the war and the pitch weights were a solution to the problem?

By Jove I bought that very book last week- there they are! There an even better pic in volume six- a nice close up showing the recessed bolts and rounded edges. I'm in business for sure! I'll post a scan in a bit- we're off to run some errands. Thanks, Les!

Chuk,
As I was looking through a few of my reference books for more photographs of the bolt-on pitch weights I noticed there seemed to be more older recycled Fw 190A's that were fitted with those pitch weights than newly built factory fresh Fw 190s.

Illustrate man :yipee been wanted to see this . . . B)

 

[paddy]

there is a little more detail to be squeezed from that first picture but not alot

Chuk,

If anyone can beat this beast into a fantastic build, it is you...

 

[chukw]

No scan (I was busy with a new front-page article)- but the dang pic is on the cover, too! The weights are rounded, split longwise and held om on by two countersunk bolts. I'm willing to bet that the 388's were larger. Maybe they were a good, simple, economic solution to a recurrent problem?

Now- make a master and cast copies of the modified blade or set up an assembly line? We'll see....

 

[phantom II]

Thanks Chuck . That's what I was hopping to see . Hard to tell about late war stuff . They had lost a lot of their skilled labor force and machinery . A lot of things no longer met earlier specs. Even the engines were being built without proper bearings. Who knows ?

Cheers, Christian B)

 

[chukw]

I'm back, guys! Here's what I've been up to- a little this-and-that...

 

[moon puppy]

Really lke that template idea, making the first and using it to shape the rest. Great idea Chuck...
