When welding up a tube structure, to avoid warping from the heat, tack around your tube in at least three places then make the final circumferential weld.

Hi John,

Thanks for the advice. I'm going to do practice welds of all the various joints I'm going to have to deal with before I start on the actual parts.

BTW, Chad Veich has graciously offered to have a go at making an oxygen regulator. If anyone else wants to try their hand at making a German cockpit doo-dad at full scale, let me know. There were a lot of do-dads in this cockpit and I'm not going to have time to build them all!

This mockup will probably end up in a museum somewhere when the filming is done, maybe even NASM since they have the original. Unfortunately time is a bit short for the filming at least, he wants to start filming early in the new year, if not some time in December. But -- small bits could be added to the cockpit pretty much any time.

One thing I could really use help with is the stick handle! I have some really clear photos of it, and dimensioned production drawings. Not an easy shape to reproduce, and it had that textured engraving all over the handle which will be pretty much impossible to reproduce easily. It will also be one of the focal points as everyone is going to want to take the stick in hand and pretend... :-)

Here's a good example of why I simply *must* do this project! Arthur Bentley kindly sent me scans of all the original German production drawings of the cockpit area. The Ho 229 is one of the few German aircraft from WWII where the original drawings survived. Most were destroyed as the allies advanced unfortunately.

So, the throttle box. I had some good photos of this, here's an example:

I started on a more or less rectangular box in Autocad, but then I got the drawings from Arthur, turns out the shape is a trapezoid.

And here's the side view showing the throttle handles:

And here's the CAD drawing. I'm simplifying the shape a bit to make it easier to construct. Unfortunately I don't have infinite time to get this thing done.

Today I'm going to start on the framework.

Here's the basic structure I built up yesterday from ABS plumber's pipe. The main spars are 3" pipe, the rest is 2" pipe. Right now it is just held together with screws. I'm experimenting with adhesives to see what will hold the best.

Heiner pointed out a great German website with lots of cockpit instrumentation info:

Going steel shopping this morning...

Gary,

Is it just me or is the actual throttle quadrant set up differently than the drawing? It looks like the throttle controls are in the rear in the plan drawings, but in the front in the actual quadrant?

Also, any idea what the second lever was for?

Gary: Use small circular movements as you feed the welding rod in and let the heat pull the molten rod and metal as you progress around the seam. Make sure you are also penetrating the actual metal to be welded in the process. Practice will make perfect---you just have to keep at it.

Good Start !!!
