In 1986 I wrote the first of the MS-Dos versions of the software to simulate Baker valve gear. Since then I have made continuous additions and improvements to add other types of valve gear and improve functionality and ease of use. In early 1999 I started converting one of the valve gears to the Windows format. I have made the software available by placing it in the public domain as freeware. There are no restrictions on the use of the software. I, the author accept no responsibility for any claim arising from the use of the software.
The programs can be used with the default settings to view operation and characteristics of any of the types of valve gear supported. They may also be used to check or change designs as all the dimensions in the gear can be modified. Performance for all types can be viewed using several different types of diagrams.
The default dimensions used in the programs are in inches and most are 1.5 inch scale. They can be user modified to suite the scale desired or for use with the metric system.

The programs require Windows 95 or higher. The instructions at this time are limited and will be expanded in the future. The Windows programs were created using Borland Delphi 5 Pro. Since some of these Windows programs are new, there are probably some bugs in them.
The programs are in Fourteen files, valgr10.zip ,valgr10a.zip to valgr10m.zip. The total programs expand to about 44MB. To use, create a folder on your hard drive and download the ZIP files into the folder. From inside the folder use an UNZIP program to unzip the files. Windows XP will unzip. To start the program use VGSTART.EXE. Or make a short cut to VGSTART.EXE and place the short cut on the desk top.
