[Sticky] Requests for help for solving problems of parts on the parts tracker - not only for part authors! part owners,

[Steffen]

This thread is intended to collect queries for help needed by parts authors on the parts tracker.

People owning certain parts, please check this thread from time to time to see if you can help us!

We need your help to be able to solve some of the problems of files on the parts tracker.

For example, a scan or photo of some real life part might be required.

To solve the problem of the 4.5V train points
http://www.ldraw.org/cgi-bin/ptreviewsum...intrack45v
, we need a scan of the moving part
http://www.ldraw.org/cgi-bin/ptdetail.cg...s/950b.dat

Its "Type 1" variant currently is out officially already as
parts/950a.dat
, and the current 950b.dat on the parts tracker "mimics" the "Type 2" variant
by simply substituting it by 950a.

HOWEVER, I got told that "Type 1" and "Type 2" differ in its rotation point.
So we cannot release 950b even as a mockup because that mockup would have the rotation point in the wrong place.

I unfortunately do not own these parts.

What would be really helpful here would be an underside scan of the "Type 1" vs the "Type 2" part.
Even a scan or photo of the underside of the whole train point could be good.

Can you help? Can you contribute? Can you send us part authors a picture or scan?

At these pictures I see not the same switch than we have modelled!

http://www.brickset.com/detail/?Set=154-1

So this might be the second variant.

Edit:
at http://ldraw.heidemann.org/index.php?page=findings
I have marked the differences I am talking about.

[Arthur Sigg]

Yes, I want to help :-)

I only own rails from this area, no points, have them given away years ago. But I will ask our LUG members through our forum. I'm sure someone has some to give away. But you have to be patient. If I understand your explanations correctly I have to find both versions.

Set 154 belongs to the "Blue Area" released 1967 - 1969

Switch Point Right Manual Blue 4.5v
Switch Points Manual Blue 4.5v

The gray points are to find in set 7852 released 1980

Right Point Manual Gray 4.5v
Left and Right Points Manual Gray 4.5v

[Steffen]

no, we only need to find the "b" version, i.e, the one contained in the "slotted" (grey) version.

the "a" version is already modeled and an official part.
see here: http://www.ldraw.org/cgi-bin/ptreviewsum...intrack45v
That page shows only files which use the "b" version.
It does NOT show the official files using the "a" version!

2 ADDITIONAL QUESTIONS:

Currently, we have an official file 948ac01.dat, modeling the blue 4.5V point. It uses 950a.dat.
As far as I am told right now, the grey 4.5V point uses a different moving part, i.e., 950b.dat.
Question 1: is this correct? Do the blue and grey versions use a different moving part 950a/b?

On the parts tracker, there are also BLUE variants using 950b.dat.
So a BLUE 948ac01.dat is official, using 950a.dat,
and on the parts tracker, there is another BLUE 948bc01.dat, using 950b.dat
Question 2: is this correct? did really 2 (TWO) versions of the blue point 4.5V exist, one using 950a.dat,
and one using 950b.dat?

can someone please measure the inner diameter (or radius) of the hands of the Duplo Figures?
(example http://www.peeron.com/inv/parts/6453cx04 )

I need this info to model correctly the diameter/radius of this bar
http://www.ldraw.org/cgi-bin/ptdetail.cg.../44670.dat
which needs to be able to be held by those Figures, for example by
http://www.peeron.com/inv/parts/44383cx1

[Arthur Sigg]

Not sure if "Sporty" has the same hands as "normal" Duplo figures ... The three circus performers, who loll around on my desk, have hands with a inner diameter of 4.9 mm (measured with a sliding gauge).

[Philippe Hurbain]

I checked on an old figure, indeed it can hold a Technic pin, so inner diameter is more or less 12 ldu.

I would have said: the same size as a normal lego stud.

I had something of this in my mind from my childhood, ut I was unsure, if I remembered it right...

Is somebody having part 4220. It is wrong modelled in our database.
I would like to know how thick are fingers, where the bar is between and I also want to know the thickness of the "central" plate (where both arm sides are connected with each other)
Thanks!
I figured out, that I own two parts of this type. They had been in the box with the extra parts. (And I never build the b-model of 8480 - so, I didn't know about these parts :-)

I could get and test 9 pieces of blue 4.5V train points (5 left / 4 right) and 4 gray ones (2 left / 2 right). Most of them were strong used or slightly damaged so it is not a bad thing that some of them have broken during removing the movable parts.

Result

- All gray points are of type B and slotted
- Alll blue points are tapered and only two of them (1 left / 1 right) are of type A
- Checked (measured) the two type A points - all parts are identical with the official points in the Part Library
- Sleepers of type B (952b, 953b) are correct designed, what I can see (measured as good as possible)

- The movable parts 950a/b (rail switches) have a remarkable different designed rotation mechanism:
- For type B the "round plate with hole" is missing,
- the rotation point has moved to "the edge" of the rail switch where one can find a similar pin (diameter 2 mm, hight 2 mm)
- the small pin attached to the sleepers (rotation point of type A) is still there, without any function now
- Please have a look to the following sketch

Hope this will give an answer to your questions. But please take into account: From just a few test objects there is no way to deduce the set of all points ever produced ...
