Thank you for the compliments. Terry I know your work , so it is a compliment indeed. This is where we are now. The inner planet gearbox is practically complete. This is gearbox in two halves There are about 40 gears here. It is not all that big either There is 15,5 mm between the...

Here are the following two updates on the clock, I will try to attach a few more photos shortly. http://www.my-time-machines.net/astro_12-18.htm http://www.my-time-machines.net/astro_11-18.htm

Shopgeezer : My client is a highly intelligent and knowledgeable clock collector, here is his description of what he wanted. Quote: On the cover of the October 2003 issue of Horological Journal was a beautiful great-wheel skeleton clock by the firm Buchanan. I was interested to see if the...

I have now altered the 12 ball races require for the center bearing assembly and made all the associated parts. These make a set of 5 concentric sleeves .. Here they are all assembled. I do appreciate all the compliments. Please take into account that this is a commercial...

Clean everything and apply a little grease on the inner side of the outer race. Replace the balls all on one side . Put the inner race back in place. The thinner components make this a relatively easy process. Spread the balls equally around the bearing and gently encourage the cage back...

Here is something others might find useful. I first read about in the M.E. many years ago. In this project space is tight. Especially in height in the Orrery. With the main center bearing assembly. the available height is 29mm. into that space we must fit 6 concentric sleeves or shafts and 12...

Kvon you are dead right. I polish with Brasso and Lacquer with an Australian product called Like Armor. We have not made a decision what the final finish will be, but if you polish brass and leave it undercoated, just don,t touch it. (why do we want to hold that part when it is beautifully...

Here is the next installment:http://www.my-time-machines.net/astro_10-18.htm

I see a Hardinge in the photos1. That is a beaut of a machine. Enjoying the build.

Terry. The way you make the distrubter blend into the overall design is perfect.

Here are a few photos of progress to date, Jupiter is complete 64 of the 105 gears in the Orrery.

Here is the next installment. http://www.my-time-machines.net/astro-09-18.htm Saturn is complete and Jupiter nearly so. Kvom, yes. You are correct. The clock is not stopped or interfered with during a demonstration. So the accuracy of the clock is not affected.

The prime criteria when given this commission was: size(not to small ),complexity and movement. When the clock is running normally, every thing moves in real time. So the fastest moons on Saturn and Jupiter complete an orbit in just over a day, But, that is a little slow so we have a demo mode...

Would the slight rise in temperature due to compression have a crank speed factor. More so on small engines. Temperature would be lost through the cylinder walls, piston and head, but that does not explain why a small engine is sometimes harder to start when warm.

About 6 foot , the brass movement is 28 inches wide 29.5 inches to the top of the brass balls and 17 inches deep . I have lost count of the number of parts but it must be heading for the 4000 mark

This is a photo of the original Mockup.It is all cardboard and rattle can paint, and picture frame material, but gives the general idea of what we were aiming for. I hope to go for the install. It will be going to Chicago. How long? There is a bout a year more of construction and then I have to...

That is a very valid question, Firstly most of the complication are sub assemblies that can be packed individually in a small boxes, likewise the two balance assemblies. The main clock movement will bolt to a base that forms part of a box. This is, in turn, placed in another box with shock...

Here is the next update at the website. http://www.my-time-machines.net/astro-08-18.htm . This is the jig I use for scribing the spokes before I cut them out on an electric scroll saw. first the inner and outer rim are scribed with a spring loaded scriber mounted in the quill of my jig...

I have used a spirit based enamel before. The results were rather nice . The color was Heritage Green. that was in South Africa in the late 90's . I left the engine behind when we left the country. The enamel had the right look about it. I must have put on 8 coats in the end.

After all the input I think i Imay change my mind and use good old enamel like they used to in the old days. If i don't use the machine it will look good any way and if I use it , there are no problems anyway.
