I am considering the HO #4 code 83 turnout tooling, but am concerned about apparent need to use ME rail. I had planned to build my layout using Walthers-Shinohara (W-S) rail, and according to the chart in the 4/9/08 note, ME rail is 0.006” narrower in head width than W-S rail. This doesn’t sound like much in the absolute sense, but it is nearly a 20% difference, and I’m a bit concerned about the appearance where W-S rail mates with ME rail at a turnout. While I’m not opposed to using ME rail throughout, ME turnouts do not seem to be available in other frog angles I will need, but do not have enough of to justify buying your tooling. So, the question is, will your tooling accept W-S rail? Thanks, Tom Reilley |

Tom, The fixtures when ordered are to be specified as to the rail you choose to use. Some instances will allow for a multi-choice, but the dimensional accuracy is corect for the rail choice design. Standards have an allowance that gives some leeway - but the base width is critical, and using a moderately wider base than designed for the fixture may be impossible. -ed- |

Ed: Thank you for the quick reply. Custom machining fixtures for the specific rail to be used will certainly help maintain precision. But I see that all the choices for assembly fixtures specify for ME rail. How does one go about specifying a different rail manufacturer? Also, it appears that the point forming jig, which is said to be for codes 70, 83, and 100 rail, will also work regardless of rail manufacturer. Please confirm. Tom |

Tom, I see the new fixture pages are indeed only ME code xx specified. You used to have to do a pull down menu to select your rail for use. You'll need to contact Ron or Tim directly for a custom fixture for a differing rail if actually required. Note that many rail profiles are, while slightly different, still allow for enough allowance of dimensional interchange. Perhaps, they have adjusted their fixtureCAD cutting for greater interchange. Never the less, using ME rail is far supperior to several other brands. You can still match up the turnout rails to a differing flex track (of the same nominal code) with only a modest swipe of a file at the connection. Yes - the point form and rail form tools are constructed to be rather forgiving in ranges of rails and getting one for the code range you chose will work well with any specific profile. -ed- |

We can cut the fixtures to work with pretty much any manufacturers rail. There is no extra charge for this. When you order a fixture, simply select the fixture with the closest equivalent Micro Engineering sized rail and during checkout just note in the comments box what rail you would like the fixture cut for. We have quite a collection of rail that we can use to confirm sizing, but if we don't have a sample of the rail you want to use on hand we may ask you to mail us a couple of short pieces. If that is necessary we will let you know. |
