Building Central Valley Model Works Turnouts: 4 Cutting the Flangeways

Please also see my updated building method at:

Central Valley Turnout Refinements

Align the hacksaw blade on the inside of one of the rail paths through the frog and very carefully start to cut. Check the depth of the cut using the NMRA gauge. When you reach that depth stop cutting.

Move to the other path and do the same.

This is what the frog assembly should look like when done. Make sure to check the flangeways with the NMRA gauge. File a slight angle on the wing end of the railheads to ease the entry of flanges into the frog.


You now have a soldered frog assembly ready to be fitted to the CVMW plastic turnout tie strip.
