Mid-April 2014

Just got a few days of good weather and took advantage by bringing the Taube outside and starting the engine up- for the first time since the sixties.

Good news and bad news, good news, it started fine and  runs fine, bad news, it first developed an oil leak from the banjo copper washers at the oil pressure sender. Fixed that, ran two days later, more bad news. Seems that the oil return from the crank case back to the tank is too slow and oil accumulates in the crank case, and eventually comes blowing out the labyrinth seal behind the propeller. Messy at best, unacceptable. Need to find a solution.  

Here are some moving shots first

Placards

Been working on the placards , using the old etched brass plate method. I first designed the label using Photoshop, then reverse-imaged them, had them printed on glossy photo paper, then heat -transferred them onto the brass plates. Next, etched them with ferrous chloride, cleaned them, painted them black, and then sanded off the high areas using 400 wet paper on a flat plate. Came out pretty good, considering first time experiment.

Elevator Bamboo

 

Starting to get the Tonkin Bamboo ready for the tail feathers. Had to buy them in bundles of 50 ( 10ft) and 100 (8ft) from an importer, very hard to find, then pick out the best and straighten them. Some were then joined into the strips connecting to the horizontal stabilizer.
