Nice work
I am just putting the Vampire Counts Coach together for a friend - definitely no resin parts in this one.
Initially I could not see how the front and rear of the coach would join to the sides as they clashed but soon realised that there is excess lead on the upper edges of the front and rear pieces. A quick snip with the side cutters and all fits perfectly.
To ensure the pieces go together at right angles I used a trusty LEGO brick clamped to the side of the coach, installed the endpiece and then used another Dollar Store clamp to keep it in place.
