Both my hand filing and my measuring proved inept, when on one of the attempts I managed to forget to take account of the radius of the big end and the whole thing came out a good 3mm too short. To be fair even if it had been the right length, it looked awful too.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For the next and hopefully last attempt I drilled all the holes and made sure that they would centre over each other on the two layers then I soldered one end together and before adding the bolts I carefully marked up the shape of the crank where it transitioned from the big end to the smaller end.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Next, I gripped the crank at an angle in the mill vice (using a parallel to ensure that the edge line was level and then milled down to my marked line on either side.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2026\/01\/Return-Cranks-Almost-scaled.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"359\" src=\"http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2026\/01\/Return-Cranks-Almost-1024x359.jpg\" alt=\"\" class=\"wp-image-7481\" srcset=\"http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2026\/01\/Return-Cranks-Almost-1024x359.jpg 1024w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2026\/01\/Return-Cranks-Almost-300x105.jpg 300w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2026\/01\/Return-Cranks-Almost-768x269.jpg 768w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2026\/01\/Return-Cranks-Almost-1536x538.jpg 1536w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2026\/01\/Return-Cranks-Almost-2048x717.jpg 2048w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2026\/01\/Return-Cranks-Almost-500x175.jpg 500w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">After some cleaning up and going around the raw edges with more solder to ensure that they remain as pairs I fitted the retaining bolts.
