Stefan's Speeder

For discussion of the issues faced when building a model or layout - how to replicate wood, what glues to use, exactly how much weathering can a Gnat take, a good source of detailing accessories - you get the picture, I'm sure.

Stefan's Speeder

Postby Geeky Gecko » Thu Dec 29, 2011 1:35 pm

I have had in my spares box a Lima n-gauge power bogie for quite a while now. It is 18mm wheelbase fitted with traction tyres on all 4 wheels, and no provision for electrical pick-up. First, I have replaced the axles with longer ones to increase the gauge to 16.5 mm. Electrical pick-up from the one side will be from the axles, from wipers on the wheels for the other side. The grooves left by removal of the tyres should not cause a problem but could be removed by removing the lip. The coarse wheels are not likely to cause a problem on 00/H0 rails.
Image
The spring steel strip is the pick up for the axles, and brass tubes fit on the axles to maintain the axles in position.

Here the bogie has been reassembled. The screw provides location for the wheel wipers. The clearance between the nut and the spring steel is small, so a piece of insulation tape has been used.

Hi Stefan...........

I know little if not nothing about electrickery so this sort of thread does inspire me to take note at least.

As an aside something I've noticed about your post though is the "img" code top and bottom of your pic's.
If as I suspect you're using the "img" option on your Photobucket links drop down, there's no need to use the "img" button whilst posting into the forum - all the code you need is right there as copied.
Not trying to be a clever dick or anything - just trying to save you the needless effort.

An interesting conversion to say the least the only place i could see that the flanges might cause an issue would be going through a set of points, unless of course you are going to do a Welsh scene and do double flanges on everything :twisted:

I have added weight in the form of lead sheet, some of it is slung loosely from the axles using tape to allow the axles to move and keep the wheels in contact with the track. 've used tape to prevent any electrical shorts.

I managed to add 20 grams and get the weight up to 34 grams.

The frame is made from some steel rail with two lengths of brass strip to allow it to be secured by screws into the original mounting holes.

The bearing 'castings' are plastic tube wrapped in paper.

A simple 'wooden' body.

I've tried it through a set of points, Michael and the only problem is the wheelbase is shorter than the plastic frog. Maybe a trailer with pick-ups...

Thanks for the tip about posting images, Andi.

reminds me of that indoor hospital railway. I know there has been a thread on this , but can't find it now. I am thinking something similar for my cheap battery train set.

Well done, Stefan!

You have inspired me to come out of lurking and to join the Forum. I have some old Bachmann 44 ton single truck power units which will work perfectly for little speeders such as yours.

I'm looking forward to the finished product!
Cheers

just found the pix I was looking for, the Longue Point Asylum Railway, but the search facility on here wasn't good enough, instead found it via Google, but included Gn15 in words. This forum is obviously high up on Google lists.

Certainly has a lot more class than my simple speeder, and a lot better finish - Well done :D

Thanks everybody.
It's stained with water based 'Antique Pine' wood dye-the drop left in the bottom of the tin. The board edges are scored with a knife and a blunt scorer. The cut lets the dye soak into the card producing dark lines and the blunt scorer indents the joins between the boards.
The simple frame and body was how I imagined a couple of apprentices would complete the task of designing and building the real thing.
It needs a starting handle, some hand rails to keep any riders from falling off, a seat or cushion, and some controls, brake, throttle, maybe a clutch pedal. These will have to wait for the driver to arrive.
