Re: BR55/G8.1 Locomotive Project

Thanks! Hi, Is there any proper wheel standards? I have been to a few different websites (http://ibls.org/mediawiki/index.php?title=IBLS_Wheel_Standard, https://www.dbc-d.de/gleisstandard.htm) and looked at different plans, there is no consistency. So I am not sure where to go from here. Thanks Ian ...

Re: BR55/G8.1 Locomotive Project

Hi, I am building in 1" scale or 5" Gauge. How much sideways float does one allow in the axles? How much clearance between the axleboxes and horns? Thanks Ian I have come upon some new information for me. It was mentioned that the drive wheels have no sideways float which seems to make sense to me.

Re: The 1" Kozo A3 that never was (a bit of a CAD rambling)

Hi Ian, Thunderskunk is right. When you are designing machine tools, you design to minimize deflection, not for strength. That is why machine tools have heavy castings, etc. Cast iron is also used a lot because it won't gall and seize at all, it "self lubricates" because of graphite in the grain st...

Sorry this a little of topic.

Hi Richard,

I was thinking of using epoxy composite for the frame. It would be great to have a thread on it!

Re: The 1" Kozo A3 that never was (a bit of a CAD rambling)

Hi Richard,

I am interested in CNC and have been thinking of making my own, do you have a picture of yours?
I will be building a BR55 hopefully and still drawing it up, I have a thread on it. I am using 3d software to model it.

Thanks
Ian

Re: BR55/G8.1 Locomotive Project

Now that I have found a suitable frame width I have had to reduce the lower width the my firebox to fit it between the frames. With this reduction, the current area is 70mm x 196mm (2.76" x 7.72"). I have lost 9% grate surface area, should I worry about this? Lengthen the firebox to make up for it? ...

Re: BR55/G8.1 Locomotive Project

Hi Ian, regarding to your question I've contacted my friend Sven, who is very knowledgeable in things like these. Here are his statement: The "symbols/markings" denotes thread sizes. These were handled differently in each locomotive factory, because of a missing common "thread standard" in Germany ...

Re: BR55/G8.1 Locomotive Project

Thanks makinsmoke, I would tend to agree with you. But what is it referring to? Maybe it references a chart that should be with the drawings?

Re: BR55/G8.1 Locomotive Project

Hi Asteamhead, Thanks for the reply, the only marking I put on the drawings is the red circle I put on there. Now that I have just written that, I see I failed to point to the points of interest. What I cannot read is the designations in the red circle, I cannot make sense of the symbols/markings. I...
