3mm Scale chassis of the LB&SCR E2 as a fixed axle, rescaled and re-designed from the 4mm verison by request.
This has been designed for 12mm gauge locomotives in 3mm scale only.
Axle holes are designed as 3.8mm's diameter to accept 1/8th Top Hat bushes. Ream gently for a snug fit.
Please note, quite a few details and features had to be removed or thickened up due to the printing tolerances that have to be adhered to in designing.
A little material at the front and back likely will need to be filed depending if you build a standard or extended tank E2 as they were a few inches different in length.
Also the rear area plugs into the body so this will also need a gentle stroke with a file to fit snugly.
At the front there is a fixing hole for the body nominally 10.5mm's diameter, the material whether WSF or FUD will self tap thus no fixing nut is needed in the smokebox saddle unless you want one.
The overall frame width is 9mm's wide, inside area is 7mm's clearance for gearboxes, thus the frames are nominally 1mm wide.
Being quite small the chassis will likely be fragile until all the workings are in, especially in the FUD material. The latter however is more crisp.
A frame spacer has been sprued on the left hand side and there are four 2mm thick thin spacers already fitted. Feel free to remove these if needed, however if using a FUD chassis it is reccomended you carefuly and slowly use a saw blade as the material can be brittle and clipping them can be risky.
