Can anyone tell me where I could get a set of plans for 5" Baker valve gear.

I tried makeing a set by scaling up a 3.5" set of casting I have but I could not get it to work . I also tried using one of the valve gear programs to get the right dimension but without much success.

Thank you

The 2 1/2 gauge association sell a pamphlet with drawings on Baker valve gear which should be straight forward to scale up.

Dockstader does work just fine but for future reference all the Dockstader programs are primarily proofing programs rather than design programs. Certainly it can be a design tool, but you must first design your valve gear, or develop approximations to your design, and the results can then be plugged into Dockstader, the behavior of the gear analyzed, and then make and view the results of adjustments made to optimize the operation.
