Two Legal Eagle builders I know have purchased GSC props. One of them is flying and is very happy with it. The other has been test run on the fuselage. Both engines are Scott Casler 45 hp 1/2 VW's. GSC seems to be the only wood prop maker that can currently provide a prop in a reasonable amount of time. I have an Ed Sterba (retired) prop, but if I need another, I will definitely buy GSC.

Today, let's think about propellers...

What Dan said, but the only torches I have ever used call for equal pressures at the regulator. I use 5 psi.
Now.
"Light the torch and adjust the acetylene flame... increasing the flow from a small flame until the flame just stops smoking... but is not roaring.
Gradually open the oxygen torch valve and adjust the flame... increasing oxygen flow so the resultant flame changes from long white, to a neutral flame = two flame cones just merge. If you add too much oxygen the flame will being to hiss-roar."
never weld with a hissing flame. That is oxidizing, and a very poor weld.
That said, I've never used a Meco, so regulator pressures may be different. (shrug) Trying not to put too fine a pernt on it but, the mainest idea of the balancing the gases procedure is that you are setting the regulators to what is called for at the tip, After your gases have made the trip through whatever length of hose you have attached, prevailing atmospheric conditions, whatever valve body (torch) restrictions exist ETC.
The mixture that reaches the tip is where the rubber meets the road so to speak. This routine simply sets the mixture at the tip with the torch valves fully open using the regulator pressure screws...And...
Setting your regulators this way has the added benefits of:- your rig will never hiss (oxidizing or burnt deposits) as long as you have set a neutral flame.
- your rig will never (hardly ever) pop at the lowest flame adjustment.
- you will always know when to go up or down in tip size.
- you are taking a giant leap to becoming and expert Oxy-Acetylene weldor, because you now know and are putting into practice something that 99.44 out of a hunnert don't do.
- it doesn't take any longer, and you walk over to your tubing joint with the rig set at minimum flame.
Sorry, I had to get all that off my chest.

Hi all, I was asked today if I would still work on the Legal Eagle. The short answer is currently, I don't. After the pandemic was finally over and normal life took over again, I had to deliver on a couple of older promises. For them, I put the Legle Eagle project on hold, with the intention to restart as soon as time would allow. However, this obviously did not work out. Ultimately, I decided to go another route and go for a Kitplane from Zenith. Currently, I am finishing the left wing. The rudder and the elevator are already done. It's a great project, but something entirely different than building from scratch.
Anyhow, for now, the Legal Eagle is an ice but not forgotten. Maybe someday I will continue this project.
Thanks for all the support when I was still working on it
Christoph

mikwr; In what part of the world ae you located? I would suggest that you see if there is someone within easy driving distance and see if you can visit him with your torch and regulators. Many of your questions will be quickly answered. If you are in VA I'd be glad to visit with you.

Search for "balancing the gases" on here... You can paint the glass on the regulators black.

I just had a great phone chat with Leonard. What an exceptional guy, very patient with a total n00b, and very encouraging. He repeated several times that I could to call back any time I needed his input. Amazing.
