Finescale - of a sort?!

Giles, an official airing for Bagshot station is being planned for October, but I very much doubt that the little engine will be allowed to attend - the show is rather scale specific!

It might be a bit too cheeky of me to ask if I could bring it along as well?

There are various jobs piling up that require attention, so here is a very brief update:

Being as mean as ever, I thought it might be a good idea to mark out and cut a trial smokebox faceplate and backhead in cardboard. It would save wastage of expensive materials if the things turned out not to fit properly?

I needn't have worried, the boiler now sits really nice and level.

These prototypes will only need some very slight tweaking: I copied the curved profiles of the bottom flanges exactly from the Horwich drawing, but surprise, surprise, they don't match photographs of the real thing!

There is still some rather unglamorous stuff to do as well as a few "interesting" bits before the chassis can be declared complete - and actually ready for the boiler. I am jumping the gun here, but it is nice to look at, and very much helps with the impression of real progress.

It must be working, as Little Man and his Grandad have both been caught recently making train noises during official inspections!!

It is a good point that you have raised Mick!

I suppose my sister knows me as well as anyone can, and she drew this on a card for me:

Of course I like to think that there is a bit more to it than pure selfishness...?!

This project started with the realisation that toys are somewhat ephemeral, and the red plastic ride-on train would be no exception. It would be played with, smashed up and then all too soon grown out of and discarded.

I wanted to make something that could be a shared plaything, that grownups could enjoy just as much, and hope that it might eventually become a family heirloom?

My son has just popped in (without Little Man) as I am writing this - and if he wasn't so busy and having to rush off again, we would probably have got the track out of the box for yet another essential "testing" session!!!

Afraid so Phil!

I hope my sister doesn't mind me saying, but she does something really, properly useful with her talent: As an accomplished "Prosthetist", she has contributed to the wellbeing of almost countless people over many years!

When my boys were young she used to send them samples, and they were able to perform the classic "Compo" trick of inviting their peers to closely observe the contents of a matchbox, horrifically revealing an awfully realistic eyeball, ear, nose or finger; to much grizzly amusement!

Talk about horrors; I decided to knock out the pair of knobbly motion weighshaft pivots on Sunday. As it was yet another hot and humid day, the dank, dark and cool cellar-cum-workshop seemed the best place to be!

It is a fantastic spider farm down there with some fairly spectacular species, but that is not the point.

Here is the bulbous, right hand casting to carve:

Note; this photo shows the ground off "modification" to allow the expansion link hanger pin to be drawn out in mid gear. The motion seen here is locked in full forward with wire wound round the reversing lever quadrant to prevent folk from fiddling with it at the NRM!)

The left hand pivot has the same lower part, but a flat top fitted over two studs...

Back in the deep dungeon; I was making good progress shaping up the little beastie...

SAM_x3299.JPG

Then this happened...

SAM_x3301.JPG

CR-A-A-CK...!

I just stood and stared at it for quite a while. All I could think was how much effort had been wasted, and how long it had taken to get this far!

There seemed to be no choice; I may be damned, but I'm definitely not going to bin it; so I shall have a go and pin it...!

Squeezing some Resin-W into the gap and clamping it up tight might cure the immediate problem, but there was clearly a weakness in the grain.

Fearing that it might fail along adjacent lines I decided that when fully set, I would drill diagonally through the break and insert a fine brass rod.

The rod was snipped slightly over long at both ends, and then lightly hammered to form a rivet.

Hopefully, that'll hold it...?!

Needless to say, I was very relieved to find that the more complex left hand carving is "shake" free!

That reminds me:

We have a rather solid pine, built-in cupboard in a chimney alcove. For some reason, one of the hefty brass door hinges kept working loose. Finally I decided to fix it once and for all. One morning I took the door off, snapped a matchstick or two and poked them in the vacant holes. Of course, driving the old screws back in was then quite hard work, and the problem was compounded by their location; requiring an awkward, left handed approach!

One of my (then) very young sons stood quietly observing the effort. Then, after a while he spoke:

"Daddy"...

Satisfied that he had briefly caught my attention, he queried;

..."Daddy... ...is it sodding thing?"

I chuckled and replied, with an upside down, half inside the cupboard voice;

"Yes son, I think it is!"

At that point he rushed away, and I heard him call out;

"Mummy, mummy"...

..."Daddy 's just screwed the sodding thing up"....!

Many years ago (30+) a friend gave me a lift to work (his name was Alan) with his wife and young daughter (four or five years old), at some point during the journey we were cut up by a boy racer causing my college to brake heavily, at which point said daughter in a very solomn tone said "daddy that bloody man's a pillock" which was followed very quickly by said wife "Alan "you and I are having words tonight!"

You couldn't of scripted it better if you tried.

The innocence of children is something to behold :D

A friend of mine had a young nephew who's parents heard a persistent bang-bang-bang coming from the lounge. When they went in there was said nephew sitting on the table and hitting it with a hammer. When asked what he thought he was doing back came the classic reply - "THIS".

Oh boy... why this sounds familiar.. Beat's a bit of hoofing and doofing right? ;) hehehe

Time and tide waits for none, and the little man, now less little, must be getting fed up waiting for Grandad to get on with his train?

Now at last the season approaches where time will be made, come what may, for "the project"! My earnest desire being to finally complete the chassis before next Spring.

There has been something nagging away in the back of my mind for a while now though. Whilst the original idea of using the toy motor and gearbox may have seemed a mildly sound one, I failed to take into account the lack of speed available and the dreadful "power drill" noise the engine makes when underway, or that over time both issues would become utterly intolerable to my grandson and the builder!

I'm afraid that a health issue now demands fairly regular appointments at my local hospital, and at my last visit, while poddling along the winding paths twixt the car park and clinic I was steadily, and quietly overtaken by a very large lady riding on an electrically assisted, but otherwise conventional looking wheelchair! As moving aside in gentlemanly fashion entailed stepping off the kerb, I had to take care where I was putting my feet and without raising my gaze, observed perchance her chassis as she passed me by!

Epiphany!...

..."Ah, hah! now that is what I need!": I exclaimed!

I could only have been happier if she had actually run me over, for then I could have had an excuse for an even closer look at the undercarriage arrangements!

Later searches online however proved to be both bewildering and frustrating. There are an enormous variety of motor and gearbox combinations available, along with a whole raft of technical information that is utterly meaningless to me. Then there seems to be an even greater confusion of prices in this particular field too? I am ruefully forced to accept that none of the "buy it now" or "best offer" quotes can even be considered, let alone any attempt made at justification!

Well my boy; looks like we are stuck with a growling snail for the foreseeable...?!

That was until this Thursday afternoon; when I chanced upon a nearby shop that I had previously been quite unaware of. One that specialised in Personal Mobility.

The lights were all on inside, revealing a grand and mountainous clutter of machinery and spare parts, but no entry could be gained. A hand scrawled notice on plain corrugated cardboard hung outside and stated:

"I am open but if door is locked I'm only five minutes away so try again later or phone ... on ..."

So I did ...

...and came away with this:-

Wphworrr - what a beast!

Even just turning over at less than 12 volts it has a massive amount of GRUNT, but runs as smoo-o-o-th as silk!

It will sit perfectly between the frames, both vertically and horizontally. Even the axle length is spot on, so should be a breeze to fit?

SAM_x4981.JPG SAM_x4983.JPG

It almost seems as if it were made to fit the model?!

But the best bit of all;

If it doesn't work out, it won't have made much of a dent in my wallet!

Quite a result, especially as going around staring at females' undercarriages normally ends up with an encounter with Her Majesty's constabulary or worse (or so I'm lead to believe) :thumbs:

Interesting!

Have you checked to see if it has a built-in 'freewheel' facility (useful for pushing dead mobility scooters) ?

Also - a twin shaft suggests this might be for a single motored device (most have a motor per wheel), so might there be a differential lurking inside?
That might not work too well unless the gearing is suitably 'mullered' to deactivate any differential activity.

Interesting question, what happens if it does have a differential within?

Well it wouldn’t be ideal for a rail vehicle, in that the coning of tread and rail would not work. But what of quartering? It seems to me that one would have to be very unlucky for this to be an issue, as the quartering of the other axle should keep the differential happily in the same angular relationship. I think it could go wrong if the crank on one side or the other were close to the front- or rear-dead-centre position, and wheelslip were to occur. This could lead to crossed rods. Seems unlikely though probably better that it doesn’t happen.

It’s easy to check if it does or doesn’t: grasp the axle ends firmly one in each hand, and attempt to turn one whilst holding the other still. If this is possible, and the motor body moves (or tries to) as a result, it has a differential. If the motor body doesn’t move, it’s one-wheel drive (drill and pin axle & sleeve, I guess) and if turning one end of the axle turns the other in the same direction, you’ve won!
