I have been looking at fabricating a M.1C control horn, I figure they were originally pressed, but would beating one into shape work harden the metal enough to skip the heat treatment?

Leatherhead,

I will have to look into this as I am certainly all for appropriate design improvements.

Thanks for making me aware of it!

Jeff, Have to defer to Leatherhead regarding the Bristol horn.

Leatherhead,

I see you are online @ 1:48 my time. Now is a good time to call me regarding Rhino, I have a free hour or so here.

The plans call for the lower bracket with the bolt holes to be 22 G.M.S.P, and the top streamlined lever section to be 18 G.M.S.T.

Easy enough to figure out the 22 / 18 Gage Mild Steel, but what is the significance of the P. and T?

Hi Joe,
I know you've already had this question answered but just my 2 cents worth.
It would seem that the plans were often written up differently but generally meant the same thing. It will often be quite specific and say something like 22g MS Plate or 1 1/8" x 17g MS Tube. Another drawing may just say 22 G Plate or even 22GMSP. I think it probably depended on who did the drawing.
Here's a couple of Camel drawings that show a difference





Cheers, Nick

Hi Nick,

Interesting to see the variations on these horns,..thank you!

Also neat to see the "Secret and Confidential" on the title block of some of these. I have several drawings like that for the early Schneider.

A reminder of what we're looking at was once very serious stuff indeed! Funny to think that posting these like we are, was likely once a death penalty offense! Watched "Eye of the Needle" with Donald Sutherland this week made me think of just that.

Thanks again Nick!

My reply to your email has been returned as "Delivery Status Notification (failure)", X 2. I can cut and paste it via Aerodrome, or reply to me with a different email account.

I have a question, perhaps someone can point me in the right direction.

Note how the cabane struts, center section, and fuselage all interact on this Hatz Classic. Note that these cabane struts are steel and the attachments to the fuselage.



I'm looking for a plans built biplane that has the following elements.

1) Steel tube fuselage / Wooden wings

2) A center section

3) Wooden Cabane Struts


Thanks!

[Joe Perkel]

Many thanks to those who have responded to the poll.

My own sentiments lie with the majority but, my wife favors the Blackburn built machine for it's interesting mix of colors. A long way to go yet, but fun to see the possibilities, a distinct technology advantage, so why not.

I have posted a mouse over image of the two on the CAD page of my website, which I think is interesting. CAD Page

It had been my intention to do this before but, I had not been in contact with the illustrator until recently.

Although it doesn't have wooden struts, the EAA Acro Sport (II) has a similar set up. I'll email you some pics of the open structure. The cabane struts are actually bolted to the fuselage which could easily be adapted to wooden struts that have steel end fittings.

I also have an idea regarding floats - I'll include it in the email as well...I ramble a bit much for forum posts!

Nice project! Great thread! Excellent web site!

FYI: I voted for the Blackburn color scheme too. More colorful.

Cheers,
