Re: Bachmann B1 - need help with pickups

I made some pickups following the suggested diagram in the instructions. I connected these to the motor and was able to run the locomotive up and down pretty well. Flushed with success I moved on to making the brakes and then found that they fouled where I had just made the pickups. I felt a bit dum...

Re: Stour Valley Dream - progress on P4 layout

I've been doing battle with the rear wall of the goods shed. While the drawing looked fine the output of the cutter had weird artifacts of weak cutting lines at various points. The result looked pretty hideous. IMG_7962a.jpg Looking at the cutting preview I could see that the good bits of the cut lo...

Re: Yard crane gears

As David's crane is Irish my instinctive response may not be valid: Tight fisted Scotsman pinched the wheelset for another vehicle. A more engineering thought is that they were removed to go around tight corners. This is Clare in Suffolk rather than County Clare in Ireland. Taking a look at the hig...

Re: Yard crane gears

I think your crane is looking rather nice. At some point I want to try and build the crane shown in this picture
https://www.transporttreasury.com/p937405195/h9ba213fd#h9ba213fd

It appears to have a 6 wheel chassis and if anyone has any more information I'd love to hear it.

Re: Bachmann B1

The weekend has been spend working on the functional springs and bogie. The cosmetic springs hold the wheels in place and also hold the functional wire springs. The spring wires are held in a hole at one end while at the other they are bent to pass through a 10BA grub screw. The grub screw can be ad...

Re: Bachmann B1

Have you missed out the bogie pivot screw? This might bring on a bout of stress or bad language. Perhaps make the dummy spring unit soon so the wheels don't keep falling out. DaveB Yep I have! I can happily screw it in to the tapped hole from underneath but going down from the top is a +%$&*$. ...

Re: Bachmann B1 -construction progress

I made a good deal of progress on the B1 chassis. I'd already prepared the coupling rods so it was time to face preparing the bearings and mounting some wheels. Each of the bearings gets numbered and the kit includes an etch with the numbers on which doubles as the functional spring hanger which is ...

Re: Bachmann B1

I found a High level gearbox in the station ( A RoadRunner + 40:1 I think ) and a used Mashima 1424 (I think). I've got them assembled and it doesn't seem to run too badly, motor starts to turn at a very slow speed and top end seems only as noisy as I'd expect from maximum welly. IMG_7947a.jpg I've ...

Re: Bachmann B1

Today I had fun making the motion bracket. I was a little daunted but the parts folded up nicely and, following the instructions and the diagram, it was not as hard as I feared. I had to solder a 10BA nut under the frame spacer because my tapping wasn't quite up to spec. IMG_7943a.jpg IMG_7944a.jpg ...

Re: Stour Valley Dream - progress on P4 layout

More progress on the goods shed today. The unrebuilt end has an interesting row of bricks just below the top of the gable. I've modeled this by putting a 1mm slot in the 3mm material and then feeding a 1mm piece with the diagonal ends of the bricks into the slot. A row of soldier bricks from 1.5mm M...

Thanks Dave I didn't mail direct as I thought you might be getting fed up with my questions by now!

Re: Bachmann B1 - remote QA required -cylinder angle?

Having got the frames made up I moved on, per the instructions, to the cylinder fronts and rears. This slid down into the slots in the frames ok and a rod through the piston gland lines up nicely with the centre of the middle axle. IMG_7940a.jpg I'm a bit confused though as the slots in the frames i...

Re: Bachmann B1 - a social isolation project

Chassis delivered from Dave Bradwell, Wheels from Alan Gibson, looks like I have a suitable motor and High Level gearbox in stock. I got the loco chassis underway. All went together quite smoothly so far. I'll take the fact the sides are straight and there is no rocking when placed on a flat surface...

Re: The Socially-Distanced Challenge - Registration Thread

I started a Thursday night with drilling out and tapping the frame spacers flat on the etch as per the instructions. I was fortunate that ...

Re: Stour Valley Dream - progress on P4 layout

Thanks for the nice comments Ralph. I've found that using the thin 1mm and 1.5mm MDF from the 4D in London works well. It is often worth putting a little bit of thin superglue into it immediately after cutting to give it strength as this means it can be filed down without falling apart. I've also le...

I built their D16/3 a few years back, I didn't think it was too bad, needed a bit of work but definitely a good starting point.

Re: Stour Valley Dream - Social Isolation project

I've been continuing with my TurboCad work on the goods shed and decided to motivate myself by cutting the main shell in 3mm MDF. I honestly expect to need more than one go at this and each one doesn't really take a great deal of material. It gives an impression of the size of the building and to be...

Bachmann B1

Hi folks

I've just purchased a 2nd hand Bachmann B1 from Hattons for £46. damaged box and a 'Warped drive wheel'
It will be interesting to see if it is a bargain or a turkey.

Re: Stour Valley Dream - progress on P4 layout

I've spend a good few hours in front of TurboCAD drawing out the goods shed. I decided I'd try and work out how to make the rather complex buttresses at the corners (well actually 3 out of 4 corners, the fourth is just plain and simple). It has taken two attempts but I'm getting there. This is cut i...
