Here's a few images illustrating progress made........
Here's the platform section for the 'Monorail'.
Had alot of hassle with assembly , very fiddley, need to rethink and alter some area's of the design so that it can be taken apart for detailing and painting.
Four stair sections are now complete.
Thanks for Looking......

Here's an update on the 'Tower' project.
Lower / narrower section at the base will fit inside a ventilation shaft and will be partially hidden.
Started adding steps with two levels now complete.
Another view on the steps.
This new platform will replace the top platform and will give access to the 'Mono Rail' boarding platform.
Monorail boarding platform in the design stage.
Thanks for looking.

Better still, a double helix spiral escalator. Or is that too ambitious?
Can't think how to acheive that mechanically, but I will think on it.

Progress seems a little slow, here;s a couple of images...
The 0.5mm and 1.0mm diameter brass rod is manufactured by 'Albion Alloys Ltd and purchased from the Bay.
That's three railing's complete, just about to start the fourth.

You could fit in a double staircase so that people could descend on one side while others are climbing on the other.
This tower will give 'Fun Town' residents one way access to the overhead monorail, there's quite a bit more designing to do and the tower needs to look complicated. Residents will then depart the monorail via the stairway on 'Vernes Tower'. Even so, the double Helix staircase is a nice feature and I will fit one in, somewhere..

Fun Town is beginning to look like one of those amazing automata that fascinated earlier generations.
Thanks Mike, You hit the nail on the head with your comment, I have just a couple of more projects before I put much more time into gettiing everything up and running.

Taking a short break from the 'Ice Cream' wagon saga, in fact the third wagon might become something else : maybe a fast food wagon serving tea / coffee. The next project has been on my todo list for years, it's an open circular tower with plenty of open stairs, iron railings and a central DCC operated lift. I've made the initial design in CAD, and modelled a few of the components, but things will change along the way and additional complexities will be added to make the structure more interesting.
Starting off with just four levels.
Here's a closer look at one level, some of the vertical posts will be altered to a more realistic profile.
Machining the railings on the BCA rotary table ( 144 x 0.5mm diameter holes ).
Two drills were broken while machining the four circular railings, not by drilling, but by wiping swarf away with a small brush : Material used was 10 thou brass sheet.
The 'Base Plates' are machined from 1.0mm thick, double sided PCB.
10 thou brass sheet is used for the 'Steps'.

Here's a couple of images of the 'Ice Cream Wagon Stall' , which is now complete.
The model is now fitted with a Gaugemaster DCC decoder and the animated bell ringer works in both forward and reverse direction. There are two LED's inside the cab and the rotating light on the roof, these are toggled ON/OFF as direction is selected on the controller.
Sprayed with enamels and then given a few dabs with weathering powders.
Thanks for Looking ..............

Made a little progress with 'Ice Cream Wagon MKII', here's a few images :
Added the additional gear mechanism for the transverse cylinders and a retaining plate secured by the motor mount 12BA screws.
Here's the roof assembly complete with an extremely slow rotating LED light.
The body now has window panels and bars bent from 0,5mm dia brass wire.
Thanks for looking.

Had this crazy idea about building a few animated wagon's that would run on DCC for Fun Town's market.
Chassis gearbox milled from solid brass with a motor gearbox asseembly from the bay.
The first wagon will be a steam driven 'Ice Cream Wagon' - with transverse cylinders.
Outer body is a good slide fit on the chassis.
A few moving parts added to the outside of the wagon.
Wagon still needs a a decoder and paintjob, but works fine on 5 volts DC.

Interesting thread, lots of good advice. I keep looking at lathes, but keep coming back to the conclusion that my old Perris Moldelmaker is all I actually need. The Tray on which it sits was "borrowed" from a works canteen back in the days when works had canteens and cooked yard square bakewell tarts and the like.
Found this while looking for missing images : Seem to remember that the Perris Company was taken over by Cowells who made slight modifications to this lathe and still sell them today. I used one these back in the 80's and for its size, it's a very nice lathe.

Hi All, I've managed to replace the lost images located in my blog's and forum entries, but don't seem able to update my image galleries. Any Idea's ?

Here is a short video taken during the development of the animated figure for the 'Ice Cream Wagon MKII'.
I will now continue with the main body and roof.
Thanks for Looking.

Here's an update on the 'Ice Ceam' wagon MKII.
Most of the parts for the animated mechanism are now complete and it's now time to assemble.
This is actually the third version of the animated mechanism, version one didn't get tested, version two would sometimes bind when operated.
The 'Base Gearbox' has been modified and a new 45 tooth gear with an offset cam added.
Mounting plate and animated mechanism added. The bent 'U' shaped wire and cam rotate the head ( which is a vertical piece of 0.5mm dia brass wire with a bend in it at the moment).
Although the mechanism still needs a modified screw and retaing nut, I was able to test and the mechanism works fine. ( The angled plate lifts and lowers the wire that operates the guys drinking arm.).
Another view fom the front.

Hi All, This is Fun Town's didi turntable that I made a few months ago but I didn't want to post until I'd managed to get the video done. The turntable will serve to showcase future scratchbuilt Fun Town models.

Spent a little time developing the mechanism for the 4mm scale animated man in CAD. The figure has been simplified and only the upper section of the body will be modelled when the time comes. Below is an animated GIF of this mechanism which looks OK, but some of those parts are tiny, the arms for instance are only 0.5mm dia, anyway, its a starting point, obviously things will most likely change during construction - time to start some modelling.

Managed to get those LED's out of my mind and make a start on 'Ice Cream Wagon MK II', this one will have an animated 4mm scale figure.
This chassis was constructed in the earlier build so at least there's some time saved here, it's the longest of the three chassis built.
As with the previous design, there will be just one set of recipricating cylinders, leaving room for the bits and bobs required for the 4mm scale animated the figure.
The body is a very snug fit on the brass gearbox.
The animated figure will be placed behind the large window, I have it in mind to model a figure that is reading a paper, he then turns his head slightly to one side, and takes a drink from a cup in the hand of his just raised arm. The whole animation will keep recycling.
Time to start on the animation.

This is magnificent! I'm really hoping to see the ice cream wagons in motion soon!
Hi Johnson044, I'm really looking forward to working on those ice cream wagons but feel the need to get a few quickies done first......
The DCC track wiring on the 'Walls Module' is now complete, didn't take long, there's only two tracks. Had to take care though, because the rails are sandwiched in between styrene sheet.
Added a third Arduino Uno board for DCC controlled lighting.
A few mods done to the wiring on the mani 'Funtown' module.
All the shop window lighting is DCC controlled, each shop / window lighting has a decoder address and function number.
Here are five new lamps constructed for the tunnel entrance on 'Walls' module - these are made from double sided PCB and brass.
Two of the lamps mounted and wired and a little grass flocking and scenic work on the baseboard.- Inspiration for this section of 'Fun Town' came from the Bramhope Tunnel entrance, which is on the Harrogate Line between Horsforth station and the Arthington Viaduct in West Yorkshire. The tunnel entrance was modelled from images found on the internet, while the remaining structure is modelled in the same gothic style.
Three lamps are mounted on this section of the wall, one is hidden behing the tree.
I'll be back on the ice cream wagons very soon -
Regards Pete

Hi All, I fully intended continuing the work on animated figures, but got sidelined into doing a little work on the layout . Due to changes made on 'Snitzl Town', the traverser has been modified and the 'Walls Module', can now be a permanent part of 'Fun Town'.
Here's a few pics.
Here's the new baseboard constructed for 'Fun Town', the brackets are used to raise the module to the correct height.
The 'Walls Module' when added, fits like a jigsaw piece to 'Fun Town'.
Still need to modify the wiring, install a couple of Arduino modules for DCC operated lighting and do some more scenery work, but its nice to see them combined again.
Thanks for Looking.....

How about a fairground organ? Some of these are extremely elaborate, with many instruments and lots of the workings exposed.
You could incorporate a musical box mechanism, to have it make real music, although perhaps the sound would be too tinny.
Hi Mike, That's a very thought provoking idea, I'll have to add fairground organ to my to do list.
Thanks

Just about done for the time being on the ' Ice Cream wagon ', the wagon's animations have been tested and everything works nice on DC, but there's more work to do in the paintshop when the weather is reasonable and there's also a DCC chip to fit. I;m hoping at some point to do a short video.
Missing the ice cream extraction pipe from the centre of the large barrel gear.
Not to protypical to have so much clutter on the roof but I thought it would be OK when in stationay market mode.
Ice cream outlet pipe has now been added.
I will now concentrate on the second wagon in the hope of adding an animated humanoid.
Thanks for Looking..

Hi All, I have now switched to working solely on the 'Ice Cream' wagon and made a little progress on the body shell and next stage of animation for outside gears. The outside gears when added will rotate, but functionally have no real purpose.
The worm and axle will transfer motion from the wheel to the outer gears, which is what I'm working on at present.
The body shell is a snug fit on the brass gearbox.
The actual rivots were done on the milling machine for precise positioning with a pointed centre punch shaped tool mounted in the collet holder and a flat piece of ebony ( hard wood ) mounted underneath the 10 thou sheet brass.
The worm and wheel will provide motion to the outside gearing.

Hi All, Managed to give the bulk components of the Sigma-Jones the 'Evapo-Rust' treatment, I used the same 'Evapo-Rust' solution as previously used on the BCA jig borer and although the rust removal took a little longer I'm quite pleased that the product did both machines. Also fitting the same 550w sewing machine servo motor as previously fitted to the BCA and Pultra watchmakers lathe.
Just noticed a little rust showng in the turn table side holes.
I didn't bother stripping down the handles / dials and screws as they looked OK.
Still need to sort out the drive belt....
.................
There is a slight chip in the pulley, but I can live with that...
Thanks for Looking.

Hi All, Just acquired this lovely little Sigma-Jones jig borer / mill from the bay, in fact, the images below were taken by the previous owner and used in the bay listing. At present, the machine is stripped down and getting the 'Evapo-Rust' treatment previously decribed when I did the BCA jig borer. For anyone interested in the history of the SigmaJones / Excel, Ultra and BCA jig borer / mills, there's a link on the lathes site : http://www.lathes.co.uk/bca/
The machine is in very good condition for its age.
I think that M.T.73 is a production / serial number, all the main conponents on this machine have this number stamped on them. Perhaps stands for Machine Tool 73.
...............
All the tooling made previously for the BCA MK3 will also fit this machine.
Regards Pete

Snitzl's Scratchbuilt Fun Town.

Hi Mikkel, The citizens have demanded a central lift and a double helix stairway, but there's another idea I'm pondering to do with a mechanism and magnet for a moving 'Wheeled Cart' and perhaps also a way to access 'Vernes Flying Machine'.
