Help with single/double slip design

Recommended Posts

With a lot of help from Martin I am still having trouble with creating a single slip and then a double slip.  The attached image is my starting point, a diamond crossing with no curves.  Surely this should be easier than the example in the Templot Companion?

The dialog box describes one half of the diamond and includes the information that it has a K-6 + V-6.  Does this influence how the slips are formed?  When I create a turnout from one of these half diamonds the result needs to be re-sized to fit.  The frogs are offset by about an inch.  Is this normal?

 

Finally, everything looks reasonably good until I ask the software to make the slip and this fails miserably!

 

I should add that, in order to follow the Companion instructions carefully I made a Keynote presentation of 97 screen grabs to run on my iPad as a source of reference, step by step.  I have followed this at least four times with no good final result.

 

Any ideas?

Hi Paul,

 

See this video: http://templot.com/companion/index.html?add_slip_roads.htm

 

Or alternatively to play it in the Templot video player you can download it from: http://templot.com/fbr/ladder_single_slip_v2.fbr

 

If you get stuck, please post the elapsed time or a screenshot of the video frame which is a stumbling block.

 

edit: p.s. I should warn you that a 1:6 slip in 00-SF is going to be quite tight and will require significant shortening of the K-crossing check rails. Be sure to select the 1:24 (A size) slip switch for a 1:6 slip.

 

p.p.s. Thanks for posting the screenshot as it's showing some bugs in the toolbutton icons under Wine. I will get that fixed. smile.gif

 

regards,

 

Martin.

I cant assist you with the design (but using the new tutorial I found it very easy to make a slip template), but with the build I find that having 4 switch blades each side on small radius double slips results in a very stiff working tiebar unless you hinge them. I have used C&L/Exactoscale metal fishplates (soldered to 1 rail only) just the job

One possibility for a more flexible method of operating the tiebars is to use rivets to link the blade and tiebar.

 

KBscale sell suitable rivets and illustrate how to use them in their downloadable booklet on track.

 

Details at:

An alternative method would be to use two tiebars at each end of the double slip - one for each pair of blades.  The tiebars could then be operated together but the stress would be reduced as each would only need to flex on two blades instead of one tiebar for all four blades.

I have reached something of an impasse.  I have successfully designed a much longer single slip but then "lost it" when trying to edit the check rails at the K crossing.  I feel sure I can now design and build a single slip but the only problem is that it requires a longer baseboard.  Such that I am now no better off than before, when I had two B6 switches.  The 2 B6 switches will not look as good but they will be more in keeping with the simple branch line setting.

 

I am going to keep experimenting and learning the ropes because I find it all quite fascinating and challenging.

 

So for the time being I am going with the simpler layout and, because I have yet to build the baseboards I can go with a 10'x2' layout instead of 9'x2'.  It is more important for me to fit in the main station buildings.  See my blog:  http://www.rmweb.co.uk/community/index.php?/blog/1581-shipston-on-stour-branch/

 

I am sorry that I cannot show the single slip - it really did look very good until I lost it!

Hi Paul,

 

I doubt that you have really lost it. By default Templot doesn't overwrite old files. Try main > file viewer to find it.

 

If you didn't save any files, try main > storage box, then files > restore previous or restore prior-previous.

 

regards,

 

Martin.

Resurrecting an old topic, how did you get on with these slips.

 

I am currently building a single slip in 2mm finnescale 1:7 crossing angle, and have reached a point (pun unintended) where I am unsure as to the best way forward.

It is the order of construction, and whether to fabricate individual swith blades etc.

 

Many thanks in advance for any assistance.

 

Regards

I did finish the double slip but have never used it. I decided to mothball Shipston and changed to 7mm scale. The point is in storage and I cannot access it for several weeks. I never fitted the tie bars as I remember but I would have to check.

 

I am sorry this reply isn't very helpful.

Thanks all for the above advice.

 

Hayfield, I have printed your order of assembly for current use.

 

Last question for now, the next construction will be a scissors crossover. Should I start with the central diamond and work ourtwards, or from one side, or end to the other?

 

Regards,

 

& thanks all, once again.

 

Ian
