I am using an earlyish set of drawings and the ME articles. I have found that, due to increase boiler length, the back of the ashpan hits the derailment angle at the back of the frames. I will move it back. The brake rods run INSIDE the frames. The ashpan side tubes are the inner width of the frames. Drop the aspan and it hits the brake rods! Martin Evans drawing shows two brake cross members, I found, after making them, they are not necessary, the brakes are not connected side to side. Two brake rod couplings are drawn by M.Evans., a further two are required ( but with only one rod connection) for the front brake. Please check against your articles……or is it me?
