Alas, it is a failure. Partly to problems on this side, but .........

but mainly because of this.

But like they say: you learn the most of you faults and errors.

Firstly back to 1:6 slips (with a jig) and then back to this one. It should be doable

09-However for a double slip we need some more lines. Therefore the second set of templates

10-And the fourth template in place

11-The third template ready for cutting to size

📷 Image no longer available Originally hosted at fbcdn-sphotos-h-a.akamaihd.net — the host went away before this archive was made.

12-And the third template cut to size

📷 Image no longer available Originally hosted at fbcdn-sphotos-d-a.akamaihd.net — the host went away before this archive was made.

13-All four templates in place

📷 Image no longer available Originally hosted at fbcdn-sphotos-f-a.akamaihd.net — the host went away before this archive was made.

14- I skipped a bit of taking pictures of template making and this is the copy of the template, sprayed with 3M Post-it glue. The sleepers are already in place and I have placed a temporary rail for alignment

📷 Image no longer available Originally hosted at fbcdn-sphotos-b-a.akamaihd.net — the host went away before this archive was made.

15-Getting the outer rail in place. I was never hoping this one would make a working slip, so I was not to keen on working to exact measurements. One of the workproceses I need to alter is getting the curvature of this rail right. I have a bendable jig which fits inside the two rails and I should use that one in this stage. Probably I need the outercurve inside the double slip as well (with a bit of temporary rail) for getting the curve right. You are building into thin air and that's not the best way to do a double slip

📷 Image no longer available Originally hosted at fbcdn-sphotos-c-a.akamaihd.net — the host went away before this archive was made.

16-The righthand side ready for soldering

📷 Image no longer available Originally hosted at fbcdn-sphotos-f-a.akamaihd.net — the host went away before this archive was made.

17-The bottom outerrail in place. with hindsight I can say that this way of making the curve is not accurate enough. Having the rails altered for the pointblade does not help either. With a continues rail it MIGHT work, but with the foot of the rail cut away for the pointblades the rail just will not curve smoothly enough this way

📷 Image no longer available Originally hosted at fbcdn-sphotos-b-a.akamaihd.net — the host went away before this archive was made.

18-The "jig-rail" taken out and ready for soldering on the other side

📷 Image no longer available Originally hosted at fbcdn-sphotos-h-a.akamaihd.net — the host went away before this archive was made.

19-And the "jig-rail" in place again

📷 Image no longer available Originally hosted at fbcdn-sphotos-f-a.akamaihd.net — the host went away before this archive was made.

20-The second outer rail in place (but again with the same issue as the other one) At the top a 1:6 half slip build in a FastTrack jig to see which way I should go

📷 Image no longer available Originally hosted at fbcdn-sphotos-d-a.akamaihd.net — the host went away before this archive was made.

21-And the second outer rail in place. Here I made an other mistake: I have taken the jig-rail out and I should not have done that. That way you have nothing to align the inner straight rails to. So I put back in the jig rail afterward

📷 Image no longer available Originally hosted at fbcdn-sphotos-a-a.akamaihd.net — the host went away before this archive was made.

22-The jig-rail back in place and the first bit of the outer point blade in place. In many workways you see rails like this being done with the left and righthand side in one piece of rail. I think it easier to do it in two pieces. Time will tell ......

📷 Image no longer available Originally hosted at fbcdn-sphotos-g-a.akamaihd.net — the host went away before this archive was made.

23-Both bottom "straight" pointblades in place. In this picture the gap between the two pointblades might look massive, but just a tiny bit of solder will fill this gap and make it invisible.

📷 Image no longer available Originally hosted at fbcdn-sphotos-e-a.akamaihd.net — the host went away before this archive was made.

24-I kept the jig-rail in place and started to work my way inward.

📷 Image no longer available Originally hosted at fbcdn-sphotos-d-a.akamaihd.net — the host went away before this archive was made.

25-Bottom half getting there

📷 Image no longer available Originally hosted at fbcdn-sphotos-f-a.akamaihd.net — the host went away before this archive was made.

26-Third stage allmost done

📷 Image no longer available Originally hosted at fbcdn-sphotos-a-a.akamaihd.net — the host went away before this archive was made.

27- Third stage done. I'm not to proud of the frog and the wings next to them. They work, but the alignment could be closer to tolerances. The top righthand "straight" rail shows on of the principal alignment problems with building the slip this way. There is a slight (outward) curve in the rail. Given other issues we will see later on in the process this is a misalignment at a crucial point. This needs another way of doing!

📷 Image no longer available Originally hosted at fbcdn-sphotos-g-a.akamaihd.net — the host went away before this archive was made.

28-The alignment of the bottom left toad (????) is also not as I want it. This is probably the result of making the template not accurate enough. I will redo that also.

📷 Image no longer available Originally hosted at fbcdn-sphotos-e-a.akamaihd.net — the host went away before this archive was made.

29-Here you see the curve in the top straight rail in beter detail. By now I was sure this first build was not going to make a working double slip. However I continued because I wanted to know if I was able to reach all the soldering spots until all the rails where in place. This is one of the issues "Aussie" was having problems with with his 1:6 double slips build in the FastTrack jigs. To be honest: I have not yet build a 1:6 double slip

📷 Image no longer available Originally hosted at fbcdn-sphotos-c-a.akamaihd.net — the host went away before this archive was made.

30-The finished product. At the point blades you can see the unsolvable issue this model is having: the pointblades just do not close nicely. Also the measurements just behind the pointblades in the direction of the inner crossing just don't add up/ However ........ it was possible to solder all the rails in place. So in principal this way of working should be a right way to make a useable 1:9 double slip. Now I need to figure out an easier way to get the alignments right and to solve the problem "behind the pointblades"

31-The left side, and yes, the situation at the frog with the wingrails is NOT as it should be

📷 Image no longer available Originally hosted at fbcdn-sphotos-h-a.akamaihd.net — the host went away before this archive was made.

32-The right side and here you can see all the issues which needs sorting

📷 Image no longer available Originally hosted at fbcdn-sphotos-f-a.akamaihd.net — the host went away before this archive was made.

33-I think the main issues are visible here. It is just that the feet of the pointblades are to wide. To solution to that would be the remove the foot to the pointblades similar the the opposite stocktrail, but that will require an other test run.

WATCH THIS SPACE

And feel free to comment and giving advice. You may have tricks I have never thought off.

Hindsight is a beautifull thing

I have placed the double slip over the 1:9 point jig and ............. with a little alteration to the jig I came probably make it work for the first stages of building the double slip as well. That should get the basic measurements right. I did the crossing without any jig and that made probably a bit to cocky.

We have a fair / exhibition this weekend in the Netherlands (Rail 2013) and I will try to source a 0.8 / 0.9 mm milling bit for my Proxxon. To be continued .......

The altered 1:9 point jig. In the hope that I can use the jig for the double slip as well

Tadaaaa: a working 1:9 double slip in code 40 in N-scale

I will add the builiding pictures ASAP

It will need one or two more to build to make them "spot-on" But at least it shows it can be done and that was the first question.

FYI a double slip like this eats 2 meter of rail for breakfast

Now all I have to do is figure out a way to make the pointblades moving. FT uses so called "hinged points" but I do like them. The point is that with a double slip you create two triangles, which makes the more or less unmovable . TO BE CONTINUED

One other issue is that strictly speaking this is a directional double slip. A true double slip is fully symetrical and can be used in both directions lay-out wise. This is still a left hand double slip and in some (50 % I assume ) you will need a right hand one
