First question: My 0 gauge layout requires 3 % grade. Should I ease or transition into this grade as I’ve done with the curves (0-72 then 0-54)?
Second question: I want to use a jig with a router to cut a very precise line parallel to the track to create a ‘roadbed’ in styrofoam. Can anyone suggest a jig to use on the track? I use a Dremel tool. Thanks
Yes, you should have an easement when you change grades. If you just suddenly start up a 3% grade from flat, there is a good chance you will have coupler problems, even with the oversized couplers found in 3 rail O. Even Lionel’s trestle set has an easement designed into it.
When it comes to marking and cutting foam for roadbed, I just took a scrap of plywood, and placed 4 drywall screws in it so just the point came through. The screws are spaced so that the tracks will be 4" apart. The first two screws are spaced 1 1/2" apart to mark one track, the second pair is measured off the first pair, and the 4" dimension allows clearance for all cars and engines down to at least 054. I just use this tool to scribe and mark the foam, then cut it with a sharp utility knife.
Using a router or Dermel with foam is overkill in my opinion, and also creates a bigger mess than necessary.
I read the second question three times before posting, but after I wrote that response, and posted it I don’t think it really answered what you wanted to know.
Before I actually started construction, I thought I wanted to do exactly what you are describing. I had the wild idea to mount a router on an old flatcar and run it down the track. Then I thought of some kind of knife arrangement. In the end, I just grabbed a straight edge and went for it with the utility knife.
Curves are more difficult, because I don’t use sectional track with specific radii. Each curve is custom, so templates won’t work for me. I just free hand them, and figure the ballast will cover the imperfections.
I hope this answers your question better.
easement, gosh yes
roadbed. A sharp razor would do the trick, but try the router out. It’ll give you an excuse to fire it up
