September 27 Wind motor assembledAfter ten days of work atop Mount Mansfield for Vermont Public Radio, I was able to get home this weekend and finish assembling the Chickering Ampico wind motor. The photos show various angles before and after restoration. The old rubber cloth was still tight enough to operate the motor but there was some gummy residue in the crankshaft bushings so those got replaced too. This substantially reduced drag on the motor. I was able to clean up the original stained finish adequately on the pneumatic boards. The graphited slide valve ports were quite worn and needed to be lapped. The slide valves got new bushing cloth and rubber cloth. All metal parts were carefully polished and the manifold block sealed and refinished. All internal passages of the valve blocks were sealed as well. This motor is now quite well sealed and refuses to be turned backward when the suction port is sealed off. Notice the uneven spacing between valve blocks and how this was corrected. 40 years from now, the only clue that this is not original factory work will be the presence of packing leather instead of cork on the manifold. I did not alter any aspect of the timing turnbuckles as these wires can easily break and are difficult to replace. The loops in the ends were not very skillfully formed originally but since the motor is working so well, I'll leave them alone.
I am now ready to assemble and tube the entire drawer. I will need some of the refinished wood pieces from John Zeiner & Sons once they are ready.
