Driving Wheels Completed

Tires for the driving wheels of WC&C #1 have been applied and are ready for shipment back to Mid-Continent.

Driving Wheels Getting Primed, Shipped Out

Today was another busy day at Mid-Continent. The wheel sets were blasted, loaded on a truck and transported to DRM to be primed. Mother Nature was on our side on this one. What a great day with the temperature in the 40s. The crew for blasting was Terry Olson, Bob Ristow, Dave Lee, Roger Hugg and Jim Connor. A big thanks to them for a hard days work. Once the priming is completed the wheels will be shipped to Chattanooga and the wheel work will begin.

There are many things to do, to keep out outside contractors and inside help going, so if you can lend a hand please let us know. There is someone in the shop 6 or more days a week right now.

Wheel Center, Driving Boxes and Smokebox Removal

Work on welding WC&C #1’s driving wheel centers is nearly complete and the tire will soon be reinstalled on the driver. Rick Peters has been working on this phase of the project. Offsite work includes the machining work done by Dave Wantz in the Twin Cities on the new driving wheel boxes. Dave has been carving out three new boxes from solid blocks of steel. “It has taken a great amount of time, patience, and skill,” remarks Pete Deets. During Pumpkin SpecialTM weekend, Bob Ristow and Jason Sobcyznski led a team to remove the old smokebox. They also began scarfing rivets on the front flue sheet in preparation for its future removal.

Magnaflux Testing of Driving Wheels

The driving wheel centers for the WC&C #1 were tested for cracks using the Magnaflux process. Heavy cable was coiled around the section of the wheel to be tested. It was then connected to a very large machine similar to a welder. The area to be checked is then sprayed with an indicator which contains fluorescent iron particles. The machine then passes a very large electrical current through the wire to set up a magnetic field in the coil as well as the iron it is coiled around. If there are any cracks in the material, a flux leakage occurs which creates a disturbance in the magnetic field similar to two separate magnets being very close together. The iron particles are attracted to the flux leakage just like the end of a magnet. A very high power ultraviolet light is then shone on the area. If any cracks are present, the concentration of the fluorescent iron particles at the crack are extremely easy to see. The results? A few cracks were detected and final analysis will be determined by the General Foreman of Running Gear.
