Just started building parts issue 1-6 and I have a problem and a question. The problem being that gears 8 and 9 do not mesh properly, the whole thing is to tight to move. The question is why given that this model is supposed to be accurate is the earth tilted at 32deg and not 23.5deg.

Thinks, you are using the right gears in the right place. Sounds a bit odd they wouldn't have got the angle right, specially after the solar system build was so good. jcmanu, hurry up and send out the issues to me, so I can have a look at the problems as well!!! Good luck sorting things out and welcome to the forum.

Had another look at it I had the collar and spring pushed up to tight, it works fine now. I checked the axial tilt again 31deg.

Good that was the problem, something for me too look out for once the issues arrive from jcmanu in Ireland. If they arrive that is, btw jcmanu I'll have to send the money from next lot of pay in 2 weeks, for jcmanu if he sees this post.

I have a similar problem with the meshing of the 8 and 9 gears. Even when I loosen the small gear, the meshing isn't very good and when I fit the rod into the baseplate (Issue 7), it is too long and extends below the level of the plastic feet. It looks as if the Bent rod has been incorrectly made or bent at the wrong angle. I will speak to the supplier today about this.

I spoke with the "expert" at Eaglemoss Publications (he is also building the orbiter to check its construction and identify any problems). He did have a similar problem and said that he also had to slightly lower the small earth gear and the bevel gear still doesn't fully mesh with it, although it all runs smoothly. He also cut back the securing screw on the earth gear to prevent it hitting the bevel gear (they may well send out a smaller replacement screw to solve this).
He also said that his earth support arm stuck out under the earth arm, almost to the level of the bottom of the feet, it only cleared the ground by a millimetre or so. It can be cut back if necessary, but in the final model the earth arm is up in the air so it shouldn't be a mechanical problem, only an aesthetic one.

I have received my replacement parts 2 and 3 with the earth support arm and bevel gear. They now fit very well, although I had to ensure that the small gear on the earth shaft (with the tensioning spring) is not close up (i.e. the spring is not fully compressed into the tube) but there is about a 1/16 inch gap.
Since I now have 2 extra small black plastic washers (courtesy of the replacement parts) I put an extra washer in above the spring (there is already one below the spring between the spring and the small gear), this then allows the spring to be fully compressed into the tube and still allows the small gear to be slightly lower so that it meshes properly with the large bevel gear.
The bottom of the earth support arm now fits properly into the earth arm and protrudes underneath just enough to fit the retaining collar and washer without hitting the table when the earth arm is on its temporary legs.
I will start my own build section in this topic and post some pictures to illustrate what I have done and the ongoing build.
