A quick coat of Railmatch "Weathered Black" followed by a bit of cleaning up the next day and the chassis is ready for a test.
Powered an half-century old H&M Clipper, it thrashes away on the rolling road nicely enough. Control will be more subtle on a better controller. I like the rolling road though as it gives all the Romford bits the chance to unscrew themselves. Two crankpins did - fixed with a dot of superglue on the threads - and one wheel nut - re-tightened with a bit more force.
Only one chip has appeared in the paint, possibly because the metal wasn't perfectly clean before priming, apart form the the hand painting has worked OK.
Back to the body now.
