Recently, a lot of progress has been made on the restoration of 4070. Lincoln Electric has finished plasma cutting the front sheets for the cab and they are in the process of being welded in place. The photo above shows the plasma cutter in action on the front sheets.
The brake hangers have been inspected and K&M Tool Machine has donated machine time to manufacture new pins and bushings for the assemblies. Old Light Mikado drawings have been located and have saved us the trouble of making new detail drawings for future record. Manufacturing processes and materials were quite different 100 years ago, and finding the drawings has saved us a lot of time in not having to "guesstimate" materials and tolerances.
We are still searching all of our storage areas to locate 4070 parts. A new storage area is being readied for the purpose of consolidating all of the parts in one area (see the lead article above). Volunteers have put a lot of effort into cleaning and sorting items in the warehouse building just for this endeavor.
Dan Pluta, an expert on steam locomotive restoration, paid a visit to Midwest in September and the committee was able to discuss our current activities along with emphasis for the immediate future. Dan has an intimate knowledge of 4070, having been involved in running and maintaining it from the mid 1970's through the mid 1980's. Main topics of discussion were the boiler, fire box and main frame. His initial inspection indicated that the boiler is in good shape with some repairs necessary as well as with the firebox. Ultrasound testing was performed a couple of years ago and those results will be reviewed in detail. The main frame has a crack that is easily repaired with weld. Repairs of this type are common on locomotives of all ages.
Dan will help formulate a comprehensive plan to assist us in moving forward in stages with defined milestones to help in the fund raising process. Midwest will also contract his services to oversee the restoration and keep us pointed in the right direction.
Volunteers are doing what they can but money is needed to continue with the major portions of the project. Any donation will be gratefully appreciated and help us move forward to our end goal of getting 4070 back on the tracks.
Anyone interested in being a part of this project can sign up online using Signup Genius or by calling the office. A sign up sheet also hangs alongside the 4070 front end display in the roundhouse. Sign up in person the next time you visit. As announced in the last edition of Marker Lights, we are also looking to start up weekday work sessions so let us know if that may be of interest to you.
Pete Stojsavljevic teaches Stephen Thomas the fine art of reading an analog microrometer. They are inspecting the bushings in the brake hangers to determine the correct replacements.
Volunteers still work to replace the cut out sections of the cab roof with new steel patches.
The wheel jack was rolled out of the steel shed so it can be cleaned, inspected and tested. The jack will be needed when we drop a set of wheels on 4070 to repair the main frame of the locomotive.
One of the forklifts in use during the "fall cleaning" backs out of the steel shed with a pallet of 4070 parts on its' forks.
