After the remarkably successful thread I thought it would be a great idea to make a similar thread for this console. I have long followed fantastic build and have always had a soft spot for this console. I hope we can come together and produce a set of plans / directions / schematic diagrams / what have you we could all follow.  
here are a couple of images to get us started off.
This console appears to also use Linolite strip lights inside the console housing.

They look like Linolite strip lights or picture lights, as used in the Hartnell column. They come in two lengths - 284mm and 221mm; two "colours" - opal (white) and clear; and two wattages - 30W and 60W.


Three of the opal were used in the original Hartnell column. These were then changed to two clear ones late in the Hartnell era, then the clear bulbs were covered with green gels in the Troughton era - kind of a precursor to the Pertwee column I suppose.

Apparently the 60W are supposed to be being outlawed in the UK and Europe, with the 30W to follow shortly - all in the crackdown on incandescent light bulbs. Time to stock up!

As to where you can get them? The UK. Pretty much everywhere has them - even Amazon.
The end connectors are known as s15, apparently - though they are a bit trickier to find.

On a side note - for the Pertwee column there was mention of the black rectangles being reused from the Hartnell column. This might have been possible. I count fifteen in the Pertwee - there were sixteen in the Hartnell. However, they do seem to be a different shape - the Hartnell ones were about 1" x 3.25". Well - that's my estimate, anyway. The Pertwee ones seem in the ratio 1x2. They could easily have been cut down, I guess.
why doesn't the Guide mention them? - Oh, it's not very accurate.
Oh? - I'm researching the new edition.


here is Jarrod's console

G'day everyone! Sorry for the delay, but been away on holiday for a couple of days.  Just put the finishing touches to my time rotor. It was fine before, but just wanted to make it look a little more authentic.  I've made some minor changes to the top three layers, and added more acrylic rods to the bottom half. It's still not perfect, as I've never seen the real one, but I'm happy with it!

Here's some pics...






Sorry about the ugg boots in this one! ;)


Also, just finished my last coat of enamel on my console panel mould, so will have some pics of that soon, too!'s all go!!!

I can't remember if Jarrod had a link to the PDFs he made for the templates of all the different layers that make up the column.  I know I have the PDFs, so I got them from him in some manner.

The sum total of the Davison/Baker/McCoy rotor photos that I took at the experience.  Two of the most surprising things were that the ends of the stars were flat, rather than pointed, and that there really is a lot of acrylic tubing arranged at the base of the rotor:

Thank you Kingpin!!! those are fantastic reference photos!!! I didn't realize those were tubes I always thought they were acrylic rods. this brings great food for thought. I'm imagining this console now.

*edit - Is that a dead bug in the console? 3rd photo from the bottom...

Are those things acrylic tubes or rods? In some photos they look like rods (which would make it sturdier) but in others they look like tubes (which would make it lighter - as in weigh less... have to be careful when talking about rotors and "light").

I strongly think there is a mixture of both tubes and rod.

I'm curious to know why the console never seems to have the red lamps inside the rotor any more? By that I mean the 5th/6th console when at the Experience or when it made other appearances.


My guess is the red bulbs (if they were pre-coloured rather than painted by the production team) are next to impossible to get hold of nowadays, so the Experience crew opted for frosted white... retaining an unmodified rotor, even though they could've possibly added some red lenses to restore it's screen accurate appearance.

In addition to square and round acrylic, there is also triangular acrylic mixed into the design... it's quite an astounding collection of light diffusion.


Great thread Glad you started this one and amazing reference pictures that does she some light on the design.  I am seeing mainly Acrylic rods in it but I just did a precursory glance.  We need to get this diagramed up.  The stars themselves could easily be laser cut from acrylic with proper measurements to provide.

I want notes, lists and answers by the time I finish this here Juicy-a-Box! WARNING: I am Thirst-ay! And it is Fruit Punch! And it is Delicious!"


Just rediscovered this excellent photo as I was saving some reference to take a stab at making some rough plans:



It's a little rough and missing bits, and without precise measurements it's only going to be useful for the general layout... but here's what I've got so far.


This new version features the solid and hollow tubing present around the base, as well as the triangular prisms that the newest photos have revealed.  I'm fairly confident on the shapes of the stars, but the rods are going to be trickier to place.  It looks like that between the lowest level, and the top few, the remaining levels are comprised of triangular prisms, with a set of eight circular rods closest to the centre.

I'll take some time later into the week to try plot out the layout of the levels between the top and bottom.

I can actually contribute on this topic!  The bulbs used in this Time Rotor are Philips Philinea/Osram (Sylvania) Linestra T10 bulbs.  They are still available!  Red lighting gels may have been used to produce the red color in the same manner as Jarrod did with the blue.

Forgot to mention that (4) white 60W and (4) 35W red colored bulbs were used.  

Also, the sockets for these bulbs are rather expensive at around $15 dollars each.  Each bulb would require (2) sockets, so for the whole time rotor, you'd be looking at $240 alone for 16 sockets.

Kingpin and Theta Sigma both excellent info. Love the diagram Kingpin. Great detective work Theta Sigma. With contributions like this I'm sure we can put together an excellent set of plans.

What length and diameter do you think feels right for the rotor's Linestra T10s?  I've found a measurement extrapolated from inches that comes in around 5.7cm, which seems right given the size of the rotor structure... and would serve as one of the few workable points of size reference outside of getting a tape measure in under the cover, or getting copies of the original plans.
