Re: Bachmann B1

I would not try to say my weighbridge is particularly accurate in terms of absolutes but where it did come in use was getting a feel for which axles were taking most load. IMG_8001a.jpg I just put a load of lead in the body of the B1 and came up with the following, these are not final figures just a...

Re: Bachmann B1

I'm just reading at this point, but slightly confused by the etching for the radius rods. I'm thinking I might be having to drill a hole that didn't get etched through but wanted to check. IMG_7999a.jpg IMG_8000a.jpg Or does the hole which ends up in the middle of the expansion link get drilled afte...

Re: Bachmann B1

I think the springing on the bogie is currently too firm. Obviously at the moment there is no weight in the front end at all. Could I suggest you get the weight in before adjusting the springing? My 2-6-0 experience suggests plenty of weight on carrying wheels is needed for reliable track holding. ...

Re: Stour Valley Dream - progress on P4 layout

A bit more progress on the goods shed as well over the weekend. I got the mortar filler added and couple of washes over the brickwork. I was trying to get the 'tired' look of the working goods shed rather than the sand blasted clear brick of the preserved building. IMG_7995a.jpg IMG_7996a.jpg The ro...

Re: Bachmann B1

So over the weekend I made some pretty good progress on the B1 chassis. I managed to make up the drop links, complete with their little tiny oil fillers and fit them to the cross heads. These really were small but went on well, fastened with the rivet for the connecting rods. The cast piston valve e...

Re: Stour Valley Dream - progress on P4 layout

As far as software for the laser is concerned, and not knowing what laser you are using, have you looked at Lightburn? https://lightburnsoftware.com/ It is an excellent piece of software and you can trial it for 1 month after which you have to pay a nominal sum. The software that we got with our la...

Re: Stour Valley Dream - progress on P4 layout

I got a bit more work done on the goods shed while I was waiting for a replacement soldering iron to be delivered. This morning I cut a load of slates into postage labels and stuck them on the roof. Then this afternoon I sprayed a couple of basic base colours, brick red on the walls and a slate grey...

Re: Bachmann B1

Thanks to Wizard of the Moor and a mail from Dave Bradwell I think I have worked out that the part 59 in the instructions actually refers to part 109 on the etch (described as the drain cock linkage). Dave suggests I don't actually fit this until later so the next task is the drop link. I've been se...

Re: Bachmann B1

So my replacement iron arrived from Eileen, I purchased the slightly more expensive version which has silicone lead and I must admit I'm rather impressed with the difference from the cheaper PVC cable. The additional flexibility means there is considerably less drag on the iron. So, on with the buil...

Re: Stour Valley Dream - progress on P4 layout

The demise of my soldering iron gives me an enforced break from the B1 (and Dave Bradwell a break from my foolish questions!). The result was some more progress on the model of Clare goods shed. I got around to fitting the overlays for the buttresses and plinths and tidy up the corners. Then I drew ...

Re: Bachmann B1

I think I'm getting there but you will have a few days peace on this topic as my soldering iron has just packed up. Order placed with Eileen for a replacement.

Thanks to Dave Bradwell for all his encouragement.

Re: Bachmann B1

Yes, absolutely nothing is fastened together at the moment.

The question is whether that is necessary, whether there is a better way and whether that is enough.

Re: Bachmann B1

I've worked on the other side slidebar and now have two that fit and slide well. I also replaced the plastic wire insulation with a standard crank pin nut, which as Dave says, recesses into the coupling rod once the bush is filed down a bit. I've also taken a gnats off the boss of the coupling rod a...

Re: Bachmann B1 advice on minimum thickness crankpin?

So I want to have a crank pin nut recessed into the rod so that there is the maximum clearance. I only have Gibson crank pin parts available and these have a bush, the running section of which is which is O/D 1.5mm, the coupling rod is currently drilled for this. The Gibson crank pin nuts are O/D 1....

Thanks for the suggestions everybody. I've persevered with the coils and made them into flange wipers. They seem to be working better so we'll see how they go.

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 ...
