I have got an OO model of a 14xx with a Comet Chassis it runs well and both the non driven forward drivers and trailing axle are sprung. It is fitted with a 38-1 gearbox, Romford Wheels and a lenz dcc chip.
My question is: Is it feasible to convert it to P4?
Two options I see, are to dismantle and rebuild from the ground up with P4 spacers or secondly, remove wheels replace with Gibson or Ultrascale wheels and axles and add cosmetic frames to cover the original (this will involve moving brake gear etc)
Is it feasible, or is there another option, or should I just buy a new chassis and start from scratch?
