excellent engineering

build from basics and understand /comprehend the entire project and then carry it through

I had to make my own as I am operating from a sealed 12V battery and not through the transformer. As the commercially available product has an input of 18 volts AC, and then has rectification, when I feed it with 12v DC, there is a big reduction of output, so I have to make my own using more basic electronic materials. This is nothing more then a wiper which touches a length of resistance wire with the ability to reverse the current built in, and a car bulb used as an overload safety device by being wired up in series to the 12v input.

The next project I mentioned I've made a start on it. I've already enlarged a hole in the footplate so the new (Actually not new!) powered chassis will fit. It is going to be a tight squeeze, but I believe it is doable, even if I may need to slightly raise the height of a part of the bonnet to achieve it. While it is likely that I may also need to do some further work on the chassis by a small amount of cutting, filing and there is the possibility I may need to remove the flanges from the centre pair of wheels (A bodge which is even found on the real railways to enable couples wheels to negotiate sharp corners), but other then that, and actually building the kit body, I see no difficulties in obtaining the results that I'm hoping for.

I remember when I first began building my first kitchen... and began understand how it all came together...

It was great when it was all completed ...from wall units and floor units.

To gas and electric [although I would get a guy to check these things out]
 
To flooring and wall tiles and wall paper -  did this three times over many years with many homes...

Including toilets and this was something I thought I could never do .....

In fact I went throughthe whole house and even to landscaping and seeing the finished product..

I did this because "it was all about saving money"  many households do the same thing    :D


Now I think it's time to "let someone else do the work - as I have reached the point where [ really cannot be bothered ]

It happens.. as you get older...

Though I cannot afford it to be done[so you end up with things falling  apart - this happens when you get older [ as you start falling apart]  old:

Lose a leg or an arm or lose internal function...  [great fun]


Excellent - but you know - I can still build train tracks   loopy:

Shame I can't show pictures, as there is no way of copying them on this tablet.

I'm currently building "Biscuit", which will lovingly be named after my cat who is now in Heaven and I really miss.
