Augie - fair enough! I'm still right though
Landlocked - it's £6.99 a week so around £350 overall
bhermann - if you're interested it published by Eaglemoss I think
Brian - not sure if it was the same kit you made but this is made from solid and plated brass and looks excellent so far

The last set of parts contains the gearing for the Earth/Moon system and the Venus arm and planet.
I've shown the construction of the Earth gear arm on its own but in reality it is constructed around the large engraved gear. It was just hard to image and show what was being put together.
Once this was complete, the gears constructed in my earlier post were slid onto the main support by followed by the large gear wheel and its attached earth gear arm. This was then attached to the support post with a grub screw.
Final part was to attach the Venus support arm with a grub screw and insert Venus into the holder.
The mechanism is starting to come together now and nicely shows the differences in orbital speed between Mercury and Venus.
Before anyone asks; no it doesn't take into account the precession of Mercury's orbit due to relativity...

The next pack contains another very nicely engraved brass part.
This is a large gear that will provide the ability to rotate the Earth/moon system so that the moon orbits the earth once a 'month'. It is also engraved with two historical planetary positions - the millennium and star of Bethlehem.
As with the other engraved part I have used some black boot polish to pick out the engraved markings to nice effect.

Onto the next section of parts.
This is primarily construction the gear wheels that also mount the Venus arm.
This comprises a brass ring, two gear wheels and a plastic hub. The hub is mounted in the brass ring and fixed with a grub screw. The gear wheels are then mounted into the hub with three screws each.
The assembled part is put aside and will be slid onto the main bar when the next pieces are complete.

Wow Jim that's really beautiful! And definitely does not look "cheap". On my brass work I antique/blacken everything. How do you keep any tarnishing agents off the brass? Gloves? It's so crisp and shiny. Well done sir, well done indeed!

Not wishing to enflame but I agree with the downgrade. Pluto is one of dozens in that same area and isn't even the biggest.....

The kit actually includes Ceres between Mars and Jupiter and Pluto and Eris out on the edge. Although it looks as though Pluto does not cross inside Neptunes orbit.

Mercury can now be added to the build.
The support arm is inserted to the main drive gear just below the Sun and fixed in place with a grub screw.
Mercury is then inserted into the top of the support arm.

Hello!
The next lot of parts have arrived and I will be able to update the Orrery to add Mercury and Venus.
First step is to finish off the Venus gear arm.
Firstly, a second gear wheel is attached using a screw and then the gear arm is fixed to the main support with a grub screw.

Finally part of the gear arm for Venus can be added to the support column. There will be two gear wheels attached but the second will be sent in the next batch. Two interlocking pieces of plastic are used to hold the gears in place with a tapping screw. Attached the first gear and awaiting the second.
The gear arm is currently loose on the support column as, again, the grub screw to attach is sent with the next batch.
Well, that's the first set of parts used and the basic structure is in place. Got to wait a month now for the next parts, but the mechanism should start to come alive then!
