Folks,

In looking at the Rokuhan offerings at the Hobby Search website, the double slip turnouts come in two flavors, left handed and right handed.  Just looking at a double slip turnout, there does not seem (at least to the ignorant like me) that there is an obvious left or right handed approach to it.  So what am I missing?  Can anyone give me an understandable explanation that would allow me to incorporate one of these Rokuhan double slip turnouts into a layout without electrical problems?

The double slips are a shorter line crossing a longer line, which way
around determines the "handedness" of them. It needs to be that way for
the geometry to work and to allow for the fact that if you have one in
something like a crossing between sets of straight lines the angled part
needs to be longer than the straight part.

Message 5 of 13 , Nov 22, 2013

then why is the 13 degree crossing not sold in left or right hand model as it is the same geometry and the short piece of track supplied with the crossing make the connection for the geometry. but in the 13 degree crossing the short pieces of track are not trimmed while in the left and right double slip they are trimmed on different sides. I have asked the question of Rokuhan, it maybe that it relates to the power routing feature of the double slip when used with a standard turnout. Not sure but will copy Rokuhan's answer when I get it.

Think carefully about how it fits together. For a "left hand" you need
the short two tracks trimmed on one side, for a "right hand" you need the
trimming the other way. In the Märklin case the geometry difference is in
the point but in the Rokuhan case its in the 'cut' tracks - but you still
have the handedness there.

See the page on 1999 which explains this.

Message 7 of 13 , Nov 22, 2013
The way it is described is that there is some special left-hand or right-hand version. If it is a true double slip switch, there should be two lefts and two rights, basically four turnouts together with a 'special' like universal cross in the middle. Basically. From any direction to any (forward) direction.

A right hand (or left hand) implies, from what I recall, a half-slip switch. That is, one track can go to the other track from only one direction or, from one side.

Message 8 of 13 , Nov 22, 2013

With a bit of thought I think I have it.

when the double slip throw bar is not energized the straight through route is selected. On the left hand double slip when the throw bar is energized it is the left hand route is selected. It does not matter in which direction you are travelling on the straight through route it is the left hand diverging route that is selected when the throwbar is energized. the opposite for the right hand version. So left hand and right hand have to do with position of the throw bar when it is energized versus the position when no energized. So as the unit is supplied as power routing double slip now you now which route is power when throw bar is energized. The double slip can be configured for  non power routing with supplied screws.

See the two links I posted earlier. The difference is in the two extra
tracks you get with the product not with the actual crossing element
itself. Those need to be different depending which way your crossing is
oriented for something like a branch line coming off a mainline or a
crossing through three lines.

As I said earlier...

Don't look at the crossing piece in the picture look at the two trimmed
tracks.

Nothing. If you take a left hand set and swap the cut tracks for those
from a right hand set, you end up with a right hand set. The handedness
is in the cut tracks in the Rokuhan case.

Message 13 of 13 , Nov 26, 2013

I have placed a copy of the Rokuhan Double slip turnout instruction sheet in the files section of this group.

electrically and physically the left and right hand versions are identical the only difference is the trimed track, for a left hand the trim is on the right at one end and the opposite for a right hand one, the trim is on the left. .

for position of the double slip when connected to a Rokuhan controller went lever is forward towards cable connector the route is the turnout diverging route and when pulled back the route is straight through. double slip.

the file is a pdf and it is not in a folder but in the root directory of the files section and file name starts with Rokuhan and files are listed in alphabetical order.
