  1. 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.
  2. 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
  3. Very nice work and thanks very much for the guitar string tip - don't know why I haven't thought of that myself. (Ernie Ball ?) Snitzl
  4. Decided to cover this topic in a little more depth and detail after visiting one of my earlier blogs for some information, only to find it totally lacking in regards to the electric's and programming details for Arduino. Arduino is not something I work with everyday, the last time I tinkered was some 6 years ago in blog 'Funtown Micro Layout - Part 1', so this blog serves as a reminder to myself, for the next time I tinker. So began a re-investigation, what files did I use for programming previously, what was the name of that website I downloaded 'Arduino' DCC libraries and function decoder code from, where's that circuit diagram for connecting DCC to the 'Arduino' microcontroller board, the list goes on. I didn't write any code for this project (just changed the decoder address), everything needed was downloaded free from :- https://rudysmodelrailway.wordpress.com/software/ Rudy provided the DCC libraries and source code for the function decoder. int decoderAddress = 217; // 217 = Walls Module,Terraced Shops = 219,The Mart = 221, used for Building Lights. Thanks for Looking : Snitzl
  5. 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.....
  6. Two of the functions in the controller that I've found very handy is having the abilty to set the maximum top speed and also reverse the motor. I use two motors on the lathe with one controller and switch the plug as required
  7. Very interesting to see you doing wheel modifications with the lathe, and I'm so glad that the motor worked out for you. I now have these sewing machine motors on three machines, here's one fitted to the BCA jig Borer / Mill.

    Ice Cream Wagon

    Hi Mikkel, As you mention, all those parts were really cheap on ebay, so I've got them ordered. Mind you, for anyone else interested, I had the last Churchward suction calibrator and there won't be anymore for at least five day's.
  9. Hi Mike, That's a very thought provoking idea, I'll have to add fairground organ to my to do list. Thanks

    Ice Cream Wagon

    HI Mikkel, That thought never even crossed my mind, guess I'll have to do another version of the Ice Cream Wagon, can't have the town's folk of 'Fun Town' eating only vanilla.

    Ice Cream Wagon

    I'll make it a top priority to get some video's sorted in the next couple of weeks, it makes sense to have video's when creating railway animations.

    Ice Cream Wagon

    Hi Mike, I'm hoping to do a collection of short video's on 'Fun town' in the very near future, I've just got to persuade myself to spend some time and get familiar with the Vegas software. The wagon has four steam driven transverse cylinder's that generate motion for the refrigeration unit inside an internal rotating barrel ( situated behind the large central gear). In reality, I doubt that such a design would be feasible but the project was enjoyable. I'm determined to have an animated humanoid in the next project. Pete
  13. Fun Town - Ice Cream Wagon. Had this crazy idea about building a few animated wagon's that would run on DCC for Fun Town's market. The original thought's were to add movement to the 4mm scale humanoids that would occupy these stationary wagons, maybe a rotating head, guy serving ice cream, someone waving, rotating cog's / gears, steam cylinder's, and roof fan's. The animated wagon's would be similar in size to the market stall wagon's and form part of the same train. With very little pre planning, I jumped straight in and made three very similar chassis with a common mechanism for the steam cylinder's and then later decided to concentrate on one wagon to see what animations were achievable in such a small space. This blog covers the construction of the first wagon and although I'm quite pleased with the end result, I'm a little disappointed that no animated humanoids were made in this first attempt, however, I do now have a few idea's to try out on the next wagon. Thanks for Looking..
  14. 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..
  15. 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. Pete
  16. 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.
  17. 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
  18. Hi all, felt it was time for an update - I did mention in my previous post that I would concentrate on the ice cream wagon to speed things along a little, but have since found myself working on all three. Made the decision that all three wagons would have some common features and later I will try to individualise each wagon. These three blocks are machined from solid brass and will house the mechanism, which will include a motor with integral planetary gearbox, gears and cams. These 45 tooth - 0.3 module gears have an offset post that will provide movement to steam generated refrigeration cylinders. There will be four of these cylinders on each side of the wagon. The motor / planetary gearbox was purchased from the bay, the 28 tooth steel gear fits on the output on the planetary gearbox. The brass components with the four side holes will house the cylinders, which are in the process of machining at the moment. So far the mechanism hopefully will provide movement to the eight cylinders and two rotating roof fans ( How to create other animations is still to be thought out ). The brass inner will later be clad with 10 thou brass sheet. Pete
  19. I've started work on what will eventually be three animated covered wagon's, these wagon's will run on DCC, and each will contain a small motor and gearbox to animate exposed gear's, lever's, cover's and the little people. The wagons will be modelled in a Jules Verne style with cast iron side's with valve's and pipework. So far , I've managed to complete the chassis for all three wagon's, but going forward, I will concentrate on each wagon in turn. First on the list will be an 'Ice Cream' wagon. Here's a look on the underside of the three chassis's, the frames are live for DCC pickup. The shortest wheelbase wagon in the foreground will be the 'Ice Cream' wagon and will contain a steam driven refrigeration unit. Thank's for Looking.
  20. This should be the last of the tooling I had in mind to build this season, it's an ER11 adaptor plate that mount's on the rotary table and should be suitable for machining romford type axles and steam valves. Construction is a combination of the ER11 collet adaptor and the chuck adaptor previously posted. Clamping slot's added on the Herbert OV miller. A removable dowel on the underside ensures concentricity with the rotary table. As before, the ER11 nut was purchased cheaply from the Bay. Pete
  21. Here's the modification to the motor mount to make it easier to adjust the motor height and tension, this became necessary when I removed the origninal 240V AC motor and replaced it with a digital variable speed sewing machine motor, I've kept all the original fitting's just in case there's a need to revert back. Started with the main block in aluminium, there was only just enough room on the Herbert to drill and ream the 14mm diameter x 85mm length hole - Had to use morse tapered drill's and reamer, no room for a chuck. Managed to find some Clarkson 'C' type autolock collet's on the Bay, so now I can use the larger collet size's. With the main block and an unmade component in Aluminium, the remaining part's were made from mild steel. Here are the main part's assembled, the aluminium extrusion was a lucky find from the scrap bucket. The two steel screw's with cross hole's in the head actually secure the tension of the belt and not the height as might be expected, the height can be adusted with the piece yet to be fitted in the above picture. ( Height can also be set by the mounting bolt ). The original bracket that connect's directly to the motor was retained. Here is the new motor and bracket assembled to the BCA. A closer look for clarity - The modification work's fine, only long term use will prove it's worth. Regards Pete
  22. Managed to make some headway with the BCA tooling so hopefully the machine will be ready to use during the winter month's, still need to do a modification to the motor mount to make it easier to adjust the motor height and I also fancy an ER11 chuck that mounts on the rotary table and is self centred by a dowel. Here's a mounting plate for a 3 jaw chuck that mount's on the rotary table. Machining the plate on the Boley Leinen lathe. Over on the Herbert OV mill - Adding clamping slot's and three holes to secure the scroll chuck. Part's gathered for assembly. Look's like one or two bur's need removing from the clamping slot, but otherise - Done. Thanks for Looking.
  23. Managed to make a few more collet adaptor's for the BCA using what was left of the 3ft of 3/4" dia EN8 bright carbon steel purchased for the ER11 Collet Adaptor, it's a good job that I didn't buy 6ft. Collet adaptor's for a JT0 drill chuck, JT1 drill chuck x 2 and a 4mm Spotting Drill. Three slitting saw arbors in 3/8", 1/2" and 5/8". ............. .... Job Done.
  24. One of the pitfall's with being obsessed with old machinery is tooling, or the lack of it. Take my BCA for example, the machine came with three imperial collet's, an 1/8", 1/4" , 3/8" and a small drill chuck. Recently, I purchased an ER11 collet holder and a few collet's so that I had an improved method for mounting dental burs, small metric cutter's, engraver cutter's and diamond bur's, I use these small cutter's quite often when machining model railway component's. This small adapter was mounted in the 1/4" collet and worked well, but the adapter position could change / creep during machining, so here are a few images as a reminder to myself and hopefully of some help to RMWEB'er's contemplating making a similar collet adapter. 3/4" diameter, EN8 bright carbon steel mounted in the 3 jaw, one end is threaded M9 x 1, the shank is turned to 7/16" dia, end is centre drilled. Setting the 20 deg angle on the compound slide : 20mm movement on the compound slide = 269 thou on the dial gauge. The 20 deg angle added. Using the same 14mm x .75 thread as used on the previously purchased ER11 adapter, I will also use the same 'Nut', which are plentiful on the bay. The die was adjusted so that the thread was cut in three stages. Collet is first drilled and then bored out with the compound slide set at 8 deg. Checking the fit with a ER11 collet. An M9 x 1 split nut is made from a piece of brass, the nut will protect the thread from the drive dog when machining between centres. With the adapter mounted between centres, the shank and 20 deg angular section's are remachined to size. Diameter of the shank is reduced from 7/16" to 10.97mm. Had major delay here getting the tailstock aligned with the headstock. Adding an 1/8" slot on the Herbert Mill. Couple of flats machined for a 12mm AF spanner. Job Done.
  25. Managed to complete all the de-rusting on the BCA jig borer and most of the part's have turned out very nice, only the chrome handle's and pulley wheel showed serious sign's of pitting from the rust. I'll probably do a little restoration on the handle's later in the year. About 1 litre of the 'Evapo-Rust' solution has either evaporated or been wiped off the part's as removed from the solution which is still active. The 'Epavo-Rust' gel was used on the vertical face, extra gel was applied periodically to area's that had dried, other's have suggested covering with cling film to prevent evaporation. The head was totally stripped, here's a pic taken during the re-assemble. The chrome handle's were very rusty in place's and the chrome had flaked, pitting from the rust is very visible. Pitting on the pulley was expected. The head assembly is now ready for installation. Job Done.
