Re: Buffer Stops

Some earlier discussions/advice on making buffer stops on my thread here https://www.scalefour.org/forum/viewtopic.php?p=55479#p55479 In the end I borrowed Allan's Studiolith bender (a lovely bit of kit) and can confirm that it is possible to bend quite sharp right angles out of steel rail without t...

Re: Making a Start - The Peak District Midland / Monsal Dale pre 1903

I've been doing a little research into the cab interior ... specifically trying to work out what happens either side of the back head and what covers the wheels. I have obtained these images of the preserved 41708 ... though this has been converted to belpair. 41708 - cab details 2.jpg 41708 - cab d...

Re: Making a Start - The Peak District Midland / Monsal Dale pre 1903

Thanks for the pep talk Allan .... I am thoroughly enjoying the process so far :D As Pete pointed out, if I had actually located the motor according to my drawing (using the high-level drawing ;) ) I would have been ok. I am making my own shorthand notes of all the little mistakes/learning curves as...

Re: Making a Start - The Peak District Midland / Monsal Dale pre 1903

What you have built does not match the drawing in that the gearbox sides are now much lower than the axle centrelines. I would question whether this leaves sufficient clearance over pointwork. You can guess how I discovered this kind of problem using an underslung gearbox with relatively small whee...

You might end up putting the ends of the cradle - or bridge - inside the frames, especially if you've arranged the platform to sit on top of them for support.

Re: Making a Start - The Peak District Midland / Monsal Dale pre 1903

So .... this is where I have got to at present. The restraining cradle is soldered to the frames with a wire 'H' hoop positioned to allow the tab to move easily up and down but not horizontally. The tab is soldered to the top face of the gearbox and set perpendicular to the cradle ensuring that it c...

Re: Making a Start - The Peak District Midland / Monsal Dale pre 1903

I would suggest that your tab could be further from the axle (that is higher) as you've got the cantilever situation here - if it works, however just leave it alone - I've seen tabs as short as this but not with a motor on the end. I suggested the top of the motor as the force on the tab and hornbl...

This is the current positioning of the motor within the fire box with the battery position indicated.

The motor position should be concealed from view by the ash pan, wheels, frames and springs etc.

Here's the killer - you have soldered all your gearbox extender arms together into one frame, haven't you?

Re: Making a Start - The Peak District Midland / Monsal Dale pre 1903

Returning briefly to gearbox restraints, I feel that I swept away the torque link rather unfairly and am including here a concept for a rattle-free design. Scangear018.jpg The pin-point axle serves as a staybar and can rock freely in the locating holes. Such a bar is traditionally called a pitman i...

Re: Making a Start - The Peak District Midland / Monsal Dale pre 1903

However my own production tends to feature small boiler-ed prototypes where the space above the gearbox/motor can be at a premium, which perhaps explains why I tend to favour wire links lower in the chassis. Given what Tim is trying to do, he is likely to have this problem. Will .... interestingly ...

Re: Making a Start - The Peak District Midland / Monsal Dale pre 1903

Would a new (well, current) 1:25k OS map not have 10m contours, and be about £10? A few will have altered but presumably the general lie of the land is still the same? Yep ... but 7.6m is better and free and already digital .... I can pull it into cad and overlay onto the 1897 25" map. The 5m ...
