My first thoughts on this whole project actually did concentrate on using the Erector Set pullies,
but the design of the ore buckets doesn't lend itself to easy use of a "V" slotted pully wheel. The
bucket castintgs use a 4-wheel roller design that are attached to the top of a cable, making it
appear as though they are rolling along it. When they reached the pully wheels, I believe there
would be stress on the casting/cable bond that would eventually break them apart.
My design, while crude at the present time, allows for the roller casting to rest against the
concave face edge of a 2" diameter pully without putting additional stress on the glue bond. The
concave edge will also provide a slight "U" that keeps the cable on the wheel.
The Jul/Aug '97 Gazette article by Nyce used Brawa ore buckets that were on a different design. I
believe they would work great with the Erector Set pully.
Thanks again for the suggestion.
