Pulleys take one...faux pulleys.

This past Friday around 11 AM I retuned from my annual physical. I was the recipient of the “you will live out the day” guarantee. Rather than faux pulleys, the design team has decided to remanufacture and make functional pulleys. After I retuning from the doctor, we knocked out 8 pulleys. After my thrilling physical exam, it felt a bit different sitting on the model shop stool, but the feeling will pass with time. I remembered that in the scrap box there were many wood discs from previous builds. Gumby made the pulleys and I installed Al tube bearings, wooden sheaves, some roof flashing for a bracket, and a functioning aileron cable control pulley set emerged. While not strong enough for a flight model, they will serve my purpose in showing how things worked in WW1 aero planes.

Thinking about our growing pulley collection I remembered that we had not tapped a great model component resource, that being the son’s Lego part collection. Having just had his 27th B’day, I do not think Toley will miss a few Lego parts. Stripping the tyres off of some small auto rims, ready made pulleys emerged.

With Gumby”s help a third type of pulley emerged. Functional in their design and construction, the sheaves on the Lego pulleys rotate.

Now that they are all painted. We have a supply to meet all our cable direction needs for this builds and for those in the future.

The Gumster managed to assemble the four pulleys that direct the aileron control cables over the upper and lower wing surfaces. Tomorrow he must assemble four slightly larger pulleys that mount slightly below the wing surfaces directing force from the ailerons to the wing mounted pulleys. He is on hos own tomorrow AM as I am off to the doctor for my annual physical examination. Looking forward or rearward to an unpleasant experience!

Gumby is in the spotlight of activity!

The sheeting of the ventral surface of the upper wing was also completed.

Attention was paid to alignment of the airfoils.

The BE 12a has visible pulleys that guide the aileron control cables, with their directional force, over the top surface of the upper wing and lower surface of the lower wing. In order for the ailerons to function the fabrication of 8 small pulleys is required. Here is the prototype that Gumby fabricated. Seven more pulleys are required.
