8BA converts well to 2.0 mm 7BA converts well to 2.5 mm 5 BA converts well to 3.0 mm I found this also to be the case when I changed all my hex headed BA steel fasteners with stainless hex drive screws on my locomotives. 3.0 mm hex drive screws replaced 6 BA fasteners, it was probably...

Hi, I have just returned to this forum after a considerable time away and found you r thread which I have added to my favourites list. I am impressed by your workmanship and the innovation you apply to overcoming obstacles. The speed at which you have progressed the Simplex chassis is also...

Another try to get the video links

Hi all, an update Video show running on air Brian Forward https://www.youtube.com/watch?v=Q-W7ow6r2dk Reverse https://www.youtube.com/watch?v=E3jGAg3vqnc

Hi all, I am building a LMS Black 5 basically of LBSC design. However I am unsure of the purpose of the tender water valve mounted on the front drag beam of the tender. Is it to control the water flow to the injector or to open/shut the return flow from the axle water pump? LBSC narratives and...

Thanks for your comments. I started it about November 2012. Having taken photographs of the locomotive I realised that, given that my workmanship finish is not great, there is something lacking and that is the milling of recesses in the coupling and connecting rods and parts of the valve gear...

I don't have an air supply. I'll have to think of someway of getting air to the cylinders.

Hi all, I am making a 3.5" gauge 2-6-0 locomotive based on LBSC's "LMS Black 5". It deviates from his design due to the fact that when I started it I didn't have the drawings or build information, I was using photographs of the model locomotive available on the internet. Hence the measurement...

Thanks kvom, so tantalising close to a solution. The essential criteria is making sure that the crankpin is set at back dead centre and the positioning of the crank (offset) is correct. Both aspects provided by the jig presumably covered by fig 17-36. Regards Brian

As said before, the return crank is positioned so that at back dead center the end of the crank is directly over the axle centerline. Is this true for all configurations of Walschaerts valve gear? I looked at the GA drawing for my locomotive and the postion of the return crank doesn't appear...

Thanks Kvom and Niceonetidy. At first reading Kvom I thought you were proposing making an adjustable eccentric rod, however this jig goes between the return crank and eccentric rod. This has me flumixed, since the eccentric rod is connected between the return crank and the expansion link. The...

Hi all, it states here http://www.modeng.johnbaguley.info/Valve%20Gears/valvegear1.htm fourth paragraph, that for the Walschaert's valve gear, the return crank can be set using a simple jig and that the lengthy set up that specified by LBSC, et al, is unnecessary. However, it doesn't show how...

Thanks Mike, it's perfectly clear now. I suspected that the LH hole was the oil pick up but thought it was a right angled fully enclosed hole which would make the opening for the oil pick up at the bottom of the stand and blocked by the bottom of the reservoir. A groove would work. Regards...

Thanks to everyone that provided input. Mike that is the exact information I require, it is probably LBSC's design for a larger model locomotive. I had nearly got there by deduction but what was and still is a concern is how does the oil get into the cylinder? The oil pick up would have to be at...

Hi all, I have attached a GA sketch of a mechanical lubricator designed by LBSC. However I don't have detailed construction data to enable me to make one. Some information I can deduce from the sketch, but there are areas that have foxed me, particulary the operation. The principle appears to...
