Davet, Eddie. Thanks for your insights into the problem of getting long wheelbase vehicles through the curves. It's reassuring to know that a similar vehicle to the one I plan will run on the track at Gilling. The CAD predicts that the minimum radius that my vehicle will negotiate is 29 feet and thi...

Hello again. The radial axle is carried in a frame which can move laterally thru an arc. It is not a turntable design. On the prototype the arc radius is 7 feet - axle spacing is 11 feet. I have done a drawing with the radial axle displaced to its maximum ie the wheel is in contact with the main und...

Hi Frits. Thanks for your interest. Only one of the 3 axles is displaceable and it is one of the outer axles. The other two cannot move laterally. The centre distance between each axle is 297mm therefore total wheelbase is 2 x 297 = 594mm. The lateral displacement of the moveable axle is 6mm each si...

Hello Charles, If you can provide me with the maximum lateral displacement of your middle axle and the distance between the outer axles, I can calculate your minimum curve. 8) Just let me know. Frits Hello Frits. Thanks for the offer of help. The displacable axle on my LNWR carriage is the outside ...

Dear all. I am currently working on a 5 inch gauge model of a LNWR 6 wheel carriage of the 1890's vintage using a works drawing that I got from the LNWR Society archive. The carriage has 2 conventional axles but the third is of a radial design which provides a steering function as well as lateral di...
