Yes we’re still here and we would like to apologize for our tardiness in updating this website. Despite the lack of an update, you haven’t missed too much work progress.
Since our last major work weekend in late April there have been some very small here and there work parties to wrap up some minor jobs, the cylinder head, cab windows, and air leaks. The list of things still to do is about a half a sheet of paper. With that said we will still have a couple of more big work days in August and September to really finish things up.
Over on the building side things have gone very well. We have all the permission we need, FINALLY, and a good portion of the funding. We will be letting a contract for the building and dirt work after July 15th. If all comes together as expected the locomotive should be in its new home by our annual fundraiser BBQ on October 15th. Make sure you mark your calendars, it should be an event to remember with a special treat that will be announced in the coming months.
Finally, some photos from this years July 4th parade in Independence. Thank you all for your continued support as we near the finish line.
On the weekend of April 30th and May 1st the C&C crew was at it again working on #18. This weekend was about finishing the installation of the rods, continuing the electrical work, and plumbing as well. Charlie was on hand to lead the charge on installing the main rods. The main rods connect the piston and crosshead to the crank pin on the second set of drivers to move the locomotive. The 18 was rolled out of the tent on our panel track, with help from a fork lift and some muscle the rods were brought into place. After install of the main rods you have to check the clearance between the piston and the front and rear cylinder heads when the driver is at the 9 and 3 o’clock positions.(or when the piston is at the end of stroke) This is to ensure that the piston does not hit the cylinder heads. There is approx 1/4″ clearance between the head and the piston in the left cylinder on both ends. The right side however has 9/32″ clearance on the rear, but 0″ on the front. This is a problem, to remedy this is was decided to grind down some excess braze on the front of the piston and machine an 1/8″ off the back of the cylinder head. Combined this should give us the approx 1/4″ clearance we are looking for. Once the head is back we can double-check this, then adjust the lateral rings and do final fit of the rods.

Electrically wiring progressed into the cab fairly well. The right side is completed, but the left side still needs work. We will need a proper fuse installed and new twist lock connection for the tender.
Some electrical work in the cab.
We were successful in airing up the locomotive to 40 lbs, however the air compressor on site is not up to the task. Rather than kill our only onsite air compressor, we stopped filling. We were able to tighten up many leaks with just 40lbs. In addition one more gauge line for the brake cylinder pressure needs to be installed. A larger air compressor will be needed to properly test the air system as well as completing the rest of the plumbing.

Charlie and Forest make small adjustments to center the rod over the crank pin so they can insert the bushing.
