I recently purchased a Steam Era Model’s J Class kit. This will be regauged to 18.37mm using P87 standard wheel profiles.
The driver wheels have been turned down and the wheel centres reduced correspondingly. Full compensation (ie suspension) will be installed using the Continuous Spring Beam (CSB) approach. This will be achieved with hornblocks from High Level Kits in the UK. I have put the horn blocks together and commenced reworking of the side frames to accommodate them (reshaped to enable the square bearing to fit).
The next step will be positioning the hornblocks, using a jig, and then soldering in place. Several other aspects will need to be addressed, such as coupling/driving rod width and associated linkages.
