Rolling, rolling, rolling…

Model Rail (UK) - - Workbench -

Shap­ing etched metal parts is sim­ple. All you need is a com­puter mouse mat and a steel rod. Cut the part from the fret and tidy up the edges with a nee­dle file.

Lay the part face-down onto the back of the mouse mat and gen­tly roll the steel rod across the sur­face. Start with the rod in the cen­tre of the part and move back and forth.

Only gen­tle pres­sure is re­quired. Check the pro­file reg­u­larly. If it needs a tighter cur­va­ture, ap­ply more pres­sure with the rod.
