Changes & Additions
Initial 9/08/03, Last updated 05/28/2017

Many folks are visiting the site often to check the Shay Project and check for progress on the Heisler.   I began to have trouble remembering what I did when so started to think about a list of changes & additions and then realized that others might find such a list useful so here it is.   Note that starting on St Patrick's Day 2004, links are provided to the changed or added page at the suggestion of a non Irish friend.  However, in early April  2006 links to Heisler Project pages before April 2006 were removed because the files were reorganized and the pages moved. Hopefully that's the last major reorganization                 

Date Description
28 May 17 The Railbus is now officially finished (till the next change) and all the webpages have been updated to match the current state of the model.  The updated pages are:
Railbus Project Overview
Railbus Frame
Railbus Diive
Railbus Body
Railbus Controller
Railbus Chargers
Railbus Accessories 
12 May 17 The size of the Heisler piston rod packing O-ring was corrected in the Heisler Engine Design Part III page.  That page was originally published in April 2006, how time flies.    
27 Apr 17 New page Railbus Controller was added to  the Railbus Project
23 Apr 17 Three new pages were added to the Railbus Project: Railbus Frame, Railbus Drive and Railbus Body.
14 Apr 17 Wow, it's been just short of three years since an update.   Had a few inquiries about whether I was still alive.    To answer that, still alive and reasonably active for my 76 years.   In fact been doing work at the Mill Creek Central track and in the shop but just didn't have the interest in updating the website.  That interest just came back.   The first new item is an overview of a new project, the Railbus Project.  That project is essentially complete so if my interest holds complete design information should follow in the next weeks and/or months.           
1 April 14 Updated the link to Larry Simoneau's Indian Lake Railroad  (  http://livesteamer.us) in the Live Steam Links page.
26 Jan 14 Five pages were added to The Heisler Project describing various  parts of the project.   The project is nearly complete now.   Hand rails, doors, windows and cab steps are still on the list to be completed.  The steam powered compressor has stopping working so that is another project needing attention.     The added pages are:

Boiler Construction IV page to the Boiler Section describing the Sand & Steam Domes, Boiler Jacket and Smoke Box Door Hinge & Dogs.

Lights page to the Electrical Section describing the Headlight and Water Gauge Light.

Running Boards page to the Finishing Details section describing the Running Boards & Steps.

Number & Builders Plates page to the Finishing Details section describing the ordering and installation of the plates.

Whistle page to the Finishing Details section describing the whistle
 and whistle valve.
 
18 Jun 13 The Logging Caboose page was added to the Small Projects section.        
13 Nov 12 The  Transporter and the Engine House pages were added to the Small Projects section.        
10 Nov 12 The  Small Projects page was added to describe  a number of small projects including trucks and log cars.        
16 Jan 12 Changes were made to the Truck Design III Page of the Heisler Project to correct errors in the truck spring part number and dimensions.         
13 Oct 11 A note was added to the Heisler Boiler and Castings pages indicating that Wayne Godshall has a full set of the Heisler castings and a finished boiler for sale.        
13 Oct 11 A reference to Jim Buckwalter's 20 ton narrow gauge Shay castings was added to the Construction and Reference Links page    
4 Jul 11 Walter Bercaw tells me that he has sold a number of Heisler casting sets and I'm now beginning to get questions and folks are finding errors and inconsistencies in the drawings.  

Everyone: please let me know of any errors or inconsistencies you find.

One set of inconsistencies involved the exhaust passages in the valve part of the cylinders and the mating recesses in the exhaust manifolds.  The Heisler Engine Design III and Heisler Engine Design IV pages were updated to show corrections.

After about 100 hours of operation the packing gland screws backed out of one of the cylinders.  They were reinstalled with lock washers and further secured with Loctite.  A note was added to the Heisler Engine Design IV page to reflect this problem.

During the process of updating the engine drawings I discovered that the drawing files on the website were old and didn't reflect some of the major changes made to the design pages in late 2009.   The EngineDesignTCWFiles.zip and EngineDesignDXFFiles.zip  have been updated to included the latest version of the engine drawings.    
20 Jun 11 Walter Bercaws' email was updated on the Heisler Castings page of the Heisler project.  Walter is now able to provide all the Heisler engine and truck castings including the wheels.

10 Apr 09 The Castings Status page was updated several times since the first of the year.  Unfortunately I neglected to upload the updates to the server.   I've given up on the investment castings and am instead having a half dozen sand castings made including the engine crankcase and the larger truck castings.   Samples of all the castings should be available by fall.  I've been making the other parts that had been previously planned for castings from bar stock.  This has went well and the results are excellent.  Photos of the machined cylinders, manifolds and universals are shown on the Casting Status page.  Detailed descriptions of the machining of these parts will be put together during late spring..  
27 Dec 08 Russ Kepler noted an error in the Shay water tank side dimension in the Shay Tanks Part I page.     The page was changed to correct the error.
17 Dec 08 The Burner and Fire Pan Design  page was added to the Burner section of the Heisler project.

6 Dec 08 The Castings page in the Heisler Project was split into two pages, the Castings Process page and the Castings Status page.  The Casting Process page contains general background information which is unlikely to change much over time.  The smaller Casting Status page will be easier to update as hopefully the castings start to become available in the next year.    Also note that there is a survey at the end of the  Casting Status page to determine the amount of interest in the Heisler castings.
3 Dec 08 The More Power page was updated to show additional information about the Shay petticoats that was sent by Mike Green of Canada.

23 Oct 06 The New Burner page describing a oil burner mixing chamber has been added to the Operation Section of the Shay Project.  
1 Oct 06 It's been a while since the site's been updated.  However, there has been progress.  Some of the Heisler engine castings have been received.  The last mold for the Heisler engine is at the foundry and the foundry is back to making the castings after a couple glitches with a few molds were fixed. The Heisler frame sides are nearly complete.  Several modifications were made to the Shay burner and it runs really well. All this will be documented in the coming months as the weather in Ohio makes it too nasty to work outside. 

Work at Mill Creek Central and updating that web site is also taking  a lot of time.  Check out the website and be sure to look at the "Trestle" and "Big Dig" projects. We're making a push there to get as much done as possible before the weather turns.

Also note that the NLW home page has been modified to show a date of the last modification in the link to this page.   This will enable folks to quickly determine the date of the latest changes.
