    Hi Folks

    I am a member of a few model railway groups and I like to give my trains a good run. My two monthly groups have coarse scale track with no points and on this Big Big stock runs well, but my local weekly club has fine scale track with many points. Big Big stock will not run well on this, with the wheel flanges touching the sleepers and the wheel back to back too small to run through the points.

    I decided to convert some Big Big stock to run on fine scale track. To my mind the Big Big bogies are okay so I just wanted to change the wheels. Buying 3′ 7” coach wheels is easy I got mine from Roxey moulding and I have also tried Slaters (7125) but the bearings supplied do not fit Big Big bogies. I have seen others have got round this by drilling through the bogies to fit the bearings but I think this ruins the look and cannot work very well with the supplied bearings due to the large hole in the Big Big bogie. My answer is to turn my own top hat bearings to suit. I am lucky enough to own a unimat SL lathe so I am able to turn some 1/8” brass bar down to 0.111” Dia  to fit the coach bogie, about 4mm long with a small flange and drilled to suit the wheel set. I then shorten the axle to 46mm.  I have converted six coaches, one Hymek and a few wagons and they all now run very well on fine scale track with no problems with points.

    The Hymek needed a bit more work, I fitted a second motor bogie and used Roxey mouldings 7W0 15 diesel fine scale wheel sets modified to take the driving gear on each.  This will now pull six coaches or many wagons around the club track with no problems.

    Hi Folks

    Dave asked to see some pictures of my modified Big Big stock running. I have some video shot on my phone but I do not know how to share this on this site.

    If it is possible and somebody could tell me how. I would be happy to post it.

    Regards

    Hi John,

    I will try to explain.

    Use your phone with the video on it to browse to this site and create a message.

    In the menu you see a picture icon.

    Tap on that and you will see a screen for adding media.

    Tap on the browse icon to the right of the location field.

    Now you can browse your phone gallery and add the video.

    Hope this helps.

    Hi Dave

    I did try that but it will not load. I get a message “file wrong type or too large” I did put the video onto my laptop but when I try from there I get a “skip to main content” message.

    The file is a MOV File 46,182 kb

    Regards

    John
