  1. Been doing a little work on my BCA jig borer, I've had this machine since the early 1980's when I purchased it for just £1.0 scrap, the machine suffered damage during transportation from Britains - London ( which manufactured farm animals / soldiers ) to Byron International - Notts ( toy typewriters / play centres ). I worked for Byron International as a model maker, the company then renamed itself as Britains Petite. The X / Y axis DRO was fitted a couple of years ago and it must be one of the best addition's made. Fitting a DRO to the Herbert 0V miller in the
  2. Sticking with rolling stock construction, here's the initial design for a 'Replenish Wagon', this wagon will supply good's to the market stall's outside both 'The Mart' and by the 'Cattle Dock' area. The wagon carries goods in tray's that match those used on the market stall's and are stored in racks. Construction will be very similar to the market stall wagon's which have split frame live chassis for DCC led lighting. Underside of the chassis, a lenghtened version of the 'Market Stall' chassis. The CAD model is created with Pro Desktop, by PTC, very old software
  3. Thanks Mike, I intend to have a dabble with video's but before I do, I need to get familiar with the software and design a youtube page. LEDS : Set yourself a real challenge, how about miniature mercury discharge lamps.
  4. Thanks Mikkel, When I started 'Fun Town' I saw myself as a model maker taking a short break from traditional historic prototype model making but it's turned into a very long short break. I feel quite flattered that some members have catagorised some of my work as 'Steam Punk' and that's understandable with all those metal gears and pinions. Once the paint's are applied, the model's morph from 'Steam Punk' to 'Steam Fun'.
  5. Thanks Dave, I can't recall if I've ever made a loco without some copperclad, it's a big thankyou to the electronics industry for creating something so useful for us model makers.
  6. First off I must apologize for the long delay in posting a blog, the truth is that for the time being at least, I cannot spend as much time as I'd like on model railway's. Therefore, after what seems like an eternity, here's part three of 'De Snitzlton'. This blog covers the design and construction of a trailing bogie / pony which I considered a last resort 'steam assisted uncoupler' method as I much preferred the original design that featured in Part 1, but this design failed to deliver. This blog also illustrates the construction and wiring of the locomotive to run on DCC. What i
  7. Hi All. With the exclusion of the steam assisted uncoupler system , here's a few images of 'De Snitzlton' in an almost complete state. The loco run's fine when DCC is wired direct to the pickup wires, but otherwise needs a gentle nudge now and again. I think that the problem maybe the thin 0.5mm diameter brass wire fitted, I will have to source some phosphur bronze pickup wire or thin strips and try that. For now, work on 'De Snitzlon' is complete, I feel the need to make progress and intend to battle through a few simpler and hopefully quick turnaround projects. 'De Snitzl
  8. Hi All, A few images of the mechanism developed for a scratchbuilt Sharman type steam traverser. The traverser is DCC operated and runs just as you would a loco, the drive and motor are part of the traverser. The gearbox housing is machined from brass and will be mounted on the underside of the traverser. Most of the gear's came from the scrap box, some needed a slight modification's. Just checking that the gears mesh OK. The gearbox is now ready for mounting. The rail wheels pictured left are free running. The large gear on the
  9. With the steam assisted gearbox put aside for the moment, work now continues to get 'De Sniztlton' finished up to the painted stage. I have my little list of jobs to complete to make this happen and these include routing motor wires, footplate retain, secure motor, brakes, steps, pickups, painting, lining and weathering. The loco will run DCC, so where's that PCB going to go ?. The loco was totally stripped down in order to machine a small slot and hole for the motor wires. The fixing plate is also machined to add routing for the motor wires and also two 14BA tapped hole
  10. Hi John, initially I thought along the same lines as you and thought, what can I disguise the trailing bogie / pony as, but later I thought, why disguise the unit at all, why not make a 'Steam Assisted Uncoupler' bogie. It wouldn't surprise me if trailing bogie's / ponie's existed for all sort's of reason's in the industrial world and 'Fun Town' was created for weird and querky modeling. I've been thinking for quite some time of building a cast iron hot air balloon complete with mechanism, obviously, there's no prototype for that. Hopefully this illustration is public domain - Invi
  11. Hi All, Thought I'd add this topic to illustrate a few of the drive mechanism's I've been working on and also add new one's that are still in the pipeline. To start, here's what I believe to be an original design for a compensated motor bogie, but I'm sure there has to be similar design's out there. Here are the components for a compensated chassis for 'De Snitzlton', a small vertical boilered 0:4:0 locomotive that requires drive to both axle's due to the transverse cylinder arrangement. The drive axle mounted on the left is fixed, while the gearbox mounted on the bevel g
  12. Here's a few images illustrating the construction of the Bramhope Tunnel entrance, this is quite a nice tunnel with gothic features. The whole structure is constructed from 0.5mm - 1.0mm styrene sheet. Stone positions are marked with a scaper and then stained with acrylic paint. The stones are textured with dental bur's mounted in a mini drill and then scrubbed with a wire brush to remove any bits. The curved ends are made up of multiple layers of 0.5mm styrene sheet. ................. Here's a few images of the now complete tun
  13. Started this vertical slide project last year and have now managed to almost complete it. The only area left to do is the attachment, don't know what to attach to it yet, probably a high speed spindle ( do I make one ?, or do I buy ? ), that all depends on what crops up. With the exception of four fixing screws, grubs screws and gib strip, all other parts were machined in the workshop. The 20 x 60 degree dovetail cutter was purcahed quite cheaply from the bay, slides are machined from mild steel on an old Herbert OV milling machine and suds are applied with a brush by hand.
  14. Here's a short video of 'De Snitzlton' with the latest steam assisted uncoupler. The transmission is provided through a trailing pony / bogie. I would have preferred a motor hidden in the coal bunker solution but as yet have failed to get those designs to work ( due to lack of space ). I'm also disapointed by the amount of operator monement, due in part to loose linkages and fits. At the moment I feel the need to make progress, so I may start a new much simpler project. Thanks for Looking'
  15. Hi Johnson044, It's nice to know that there's interest in this thread, "Steam Punk" genre has been mentioned a few times in my postings and I think it's a fair classification. The design and building of the uncoupler mechansim for 'De Snitzlton' has been a real headache for me and two further failed attempts made on the uncoupler have not been posted here for fear of boring everyone to death. Time has also been been spent making jigs and index mechanisms for the lathe to improve concentricity of those tiny 0.15 module gear's used in the mechanism. De Snitzlton has been run by connecting wires
  16. Hi John, I'm trying to resolve uncoupler design on De Snitzlton and thought maybe I should find a solution before posting, I'll have an update in the next few weeks, just waiting for some milder weather and then I can start work in my workshop.
  17. Here's a little additional information regarding 8mm watchmaker collets (stepped collets). The above, is a list of 8mm collet manufacturers with thread and body details, notice the two variation's in thread diameters, I have both types i my collection and therefore also require two draw bars. The stepped collets are numbered 1 to 5 with a range of approximatley 4.0mm dia to 22.0mm dia in 0.2mm increments. Here's a small bogie wheel mounted in a stepped collet. The one negative learned so far is that the crankpin on driver wheels, get's in the way when mounted a
  18. Hi All, The weathers been so nice here in the UK this last couple of day's that I decided to get out into the workshop and make another index plate ( yes I've got more gears to make for de snitzlton locomotive) . Here's the new 39, 45,50 and 55 hole index plate made as previously described - drilled and countersunk with a centre drill. After recounting the number of holes in the first plate virtually every time I needed to make a new gear, I decided to engrave the plates with a Taylor Hobson 2D pantograph. After engraving, the numbers are given a dose of felt t
  19. Regarding AdamsRadial's sound advice on machining the jaws, it's also worth noting that if there is excessive wear on the scroll threads or jaw threads of the chuck, then you are unlikely to get the jaws true, you may improve concentricity to within a few thou. Also, many jaws are hardened, if so, you will need to attach a grinder and cover the lathe bedway surfaces with some form of protection.
  20. It just happens to be a very big bits box. I think that I must be getting a bit slow, it took me a few minutes to figure out what was what.
  21. Here's a link to a step by step guide that should in the least provide food for thought.... Tile that Roof..
  22. Hi richbrummitt, Thanks for the offer of a swap, but after sleeping on it, I prefer the metric thread over the much courser imperial thread on these small watchmaker slides, my favourite slide has 0 - 25 thou dials. I probably don't need to redo the dials either, as long as I remember that 10 on the dial is 0.1mm.
  23. Decided to post a bit of a tutorial on using the new index plate, vertical slide, milling spindle and compound / cross slide assembly and I must say that it was quite an enjoyable experience without any concentricity fustrations. This was the first time I'd used any of these items, all of which were purchased earlier this year. The only surprice was the Pultra 1750 compound / cross slide, the dials read 0 - 100, which I presumed to be 100 thou per revolution, in fact they are both 1.0mm per revolution, so it's either new dials, or new screws and bushes. A job for the warmer months next year.
  24. Not seen anything quite like it, looks very interesting and unique, I see that you are using two stepper motors and timing belts. Can't imagine getting my head around the arduino code though. Look forward to seeing more.
  25. I'd love to illustrate the process of making gears for anyone interested, but I'm not sure from reading the intro pages of Lathes and M/C Tools that this would be appropriate for this topic. The topic seems to cover lathes and machine tools with a liitle advice on how to use them. What I intend to do is turn a gear blank on a lathe in the usual way, then remove the drive belt and lock the lathe spindle into 26 equi spaced indexed positions. A vertical slide / spindle is then attached to the lathe bed, in effect, converting the lathe into a mini milling machine. One gear tooth is cut, then th
