I plan on N scale roadbed because my whole (HO) layout is branchline switching. I wonder if the Walthers TT is sized for 1/4" roadbed? If it is, it will be uphill to the TT as the N scale roadbed is 1/8".
I dread the thought of lowering the TT rim that 1/8".
I do not have the TT at this time to see the rise of the rails.
Bruce,
I am using Atlas HO scale code 83 flex track. Both my Walther’s TT and the track are set directly on a flat section of Homasote. The thickness of the TT rim closely, if not perfectly, matches the thickness of the track ties. Thus, I have cut off a couple of ties on the radial and lead in tracks with the rail overhanging the rim just to the edge of the pit. No problems. Thus, shimming up the TT pit with a few scraps of your N scale roadway material should do the trick.
Good luck!
No worries mate. You can use the N scale cork. Just place your N scale cork around the rim of the turn table. It include templates for cutting the holes in the cork also.
I agree with Roger and Michael. Since the TT lip rests on the surface that it is mounted to, you simply have to match the height of the roadbed with the same material under the lip of the TT, all the way around the lip.

Yes, that is true, Bruce. I found out when I went to get my approach lead of Code 100 to match at the rail head height with the Code 83 (I think?, maybe Code 70) on the bridge of the Walthers indexed/built-up 90’ turntable six years ago. I had used cork roadbed up to the plastic lip of the turntable pit, and some small pieces of the roadbed under the lip as blocking. By the time I got my rails onto the lip to meet the bridge rails, I found I was too high. So, I had to use a thin stone in a Dremel-like Crappy Tire version hand rotary tool to file two parallel grooves into the lip so that the tie-less rail ends could lie inside those grooves. That did very nicely.
Bruce, don’t forget to dress the very tips of those two rails before you place them and set them there for good. Bevel them to match the ends of the bridge rails as the Walthers assemblers have done. That’s an important step you should not miss.

Totally agree with Crandell on that point. It is a most important step.

A picture is worth a thousand words. Here are two thousand words. This is the 130’ TT. The grey plastic strip on the track is a track alignment tool, great for aligning the bridge track with the approach tracks.
