August 2010 Work Weekend

On yet another steamy August weekend, the volunteers at the MCRR continued their primary restoration project, the reassembly of the Six. The general procedure is "pick something off the flatcar and put it back on the Six."

Not long ago, the air brake parts were sent to a rebuilder in Pennsylvania. The parts are due back at the shop very soon.

Abe C. and his dad, Eric C., finished the machining on the dry pipe for the spool valve and were able to get the whole affair back into the boiler. While it only takes a few words to describe what they accomplished, it took nearly a hundred hours of labor to complete the work.

During this work weekend's Friday evening, Dustin B. and Elliot H. mounted the mechanical lubricator and the two running boards onto the chassis.

Another seemingly trivial project was getting the bell onto the boiler. With the increased diameter of boiler jacket, the bell mount (like nearly everything else) didn't fit. Elliot H. made various modifications to the mount and Dave O. "lengthened" the studs to accept the modified bell mount.

Abe C. and Elliot H. also completed the modifications to the boiler jacket on the unit's left side to accommodate the air compressor. With the help of Walt O., the air compressor was ready to mount onto its frame by late Saturday.

With the dry pipe in place, another opportunity arose. The new dry pipe didn't protrude into the smoke box as far as the previous dry pipe incarnation. The length change caused the pipes leading up from the steam cylinders to not meet the manifold which connects to the dry pipe!

With the skills of Dave O., the problem was "easily" resolved. The dry pipe/steam cylinder connector pipes were sliced in two and a steel "doughnut" placed in the gap. Unfortunately, the aged manifold attached to the dry pipe broke when the connecting pipes were attached. As of the close of Saturday, the plan was for Dave O. to fashion a new manifold from boiler flanges and steel piping. We should see the finished product in a week or so.

Nathan V. hands the MIG welder gun to Dave so he can tack weld the steel doughnut into place.

Dave O. grinds a bevel into the connector pipe to facilitate welding.

Randy and Nathan V. cut a doughnut from a piece of 4" diameter steel pipe.

While work was going on in the front of the locomotive, Abe C. crawled inside the firebox to measure it for the fire brick purchase.

It might look the boiler is giving birth, but it is really Abe C. crawling out of the firebox door after measuring the inside.

Besides altering the size of the bell mount, the boiler jacket needed a bit of adjusting. Elliot H. uses a flap disk on the angle grinder to remove jacket material which provided for the proper fit of the mounting bracket.

Braden H. lowers the bell into place.

To make the boiler jacket fit properly behind the air compressor mount, we had to make some new fasteners. Abe C. drills the holes for a nut plate which will be used to hold the jacket sections together.
