Wonderful job Ed! Great idea making the jig out of aluminum. Finally, a reason to be happy that aluminum does not solder easily.
How will you attach the prop supports to the hull?

One tape was the width of the hull planks and the other was very fine, the width of the seams. I laid down one course of wide tape starting at the shear. Next, I applied one course of the narrow tape right next to the wide tape. I alternated with wide tape and then narrow tape until the entire hull was covered with tape. I then removed all of the wide tape. I applied three coats of Krylon spray paint to the hull. Then I removed the narrow tape. This left raised areas resembling wide planks with recessed areas representing the seams. I finished by applying several more coats of Krylon to the entire hull. Here are some pictures. They are not the best but if you click on the photo and then click again, and then click one more time to enlarge, you will see the effect.
Interesting technique with beautiful results. Thanks for sharing it!

Hi Greg,


Good to hear from you. I just finished making the pads and soldering them onto the prop supports. The pads will have the corners rounded off and all four corners will be drilled for some small pins. I will attach the pads to the hull with epoxy and epoxy the pins in place. The supports need to be cleaned up and the 4 straight arms will be filed, sanded and shaped to look like the original supports.


I soldered the support pads in place on the hull. To keep from burning the hull I placed a 3 X 3 inch .005 brass shim stock between the pads and the hull. It worked pretty good there are no burn spots on the hull.

Very Nice, Ed. They will be just like the original. I'm surprised to learn about your success with protecting the hull from the heat with shim stock. I'll have to keep that one in mind.

Greg,


I used a soldering iron with a very large tip. I didn't have to leave the iron on it for very long.

Aerominded,


I used Stay-Brite solder and Stay-clear flux. It has silver in it. I use this type of solder in case I want to chrome plate it. The soldering iron is a (Unger brand) 33 watt with a large tip 5/16" wide.


The solder is from Micro-Mark.
