Re: Why are these springs necessary
I think that there is a basic mistake about the spring forces needed in this solution: https://www.chaski.org/homemachinist/download/file.php?id=100055 Here in mid position, the resulting force on the switch blades is zero, and it rises only linear (from zero!!) when moving the nylon block, starting...

Re: Charlie Dockstader's Valve Gear on the Computer
I'm afraid it's too late for not hijacking the other thread :lol: But thanks. Just added this there: https://www.chaski.org/homemachinist/viewtopic.php?p=470951#p470951 So if anybody should have the source code, surely future users and programmers would be glad to find it on Github! As far as I know...

Re: Online Program for Valve Gear Design
The .pas files in the zip file are much too small. They cannot be the source of the .exe files. I cannot code Pascal, but I am sure.

Re: Online Program for Valve Gear Design
I only played with Dockstader's program. Call up the program and you get a working model, then I'd change the length of a rod or link, or a port size and see what it did to the ven diagram and such. I only PLAYED with it. I used it to help me visualize what is happening in the timing and such. It w...

Re: Online Program for Valve Gear Design
Thanks for your effort. The final programs are not my question, but the source code which could be newly compiled or modified, or extended with further valve gears.

Re: Online Program for Valve Gear Design
Charles J. Dockstader died sometime after 2008 I believe. He and I used to talk back them. He sent me a final copy of everything he had. I think I posted that on here back then. I could not find an according thread title in your threads from 2008 to 2012. Could you perhaps have posted that somewher...

Re: Online Program for Valve Gear Design
"I did modify various dimensions in the programs" - do you mean Dockstader's programs (>1), or his program and mine??? There are several accesses with differently limited rights on the VGC website. Charly has passed away years ago. http://chaski.org/homemachinist/viewtopic.php?t=90913 By t...

Re: Online Program for Valve Gear Design
Depends on what you think "this" is ;-) Dokstadoodle (or whatever his name was ;-) ) needs each detail dimension from you and shows a valve gear and diagrams resulting from these dimensions. Optimization is not included there in any way but has to be done manually. One of its users told me...

Re: Cagney valve gear question
I did not mean that one material valve gear but that new type of valve gear structure which probably never needs to be layouted manually because its "inventor" supplies the according calculation software online.
