This caused more than a few mutterings. One thing that I noticed was that in retaining the Dereck Mundy Crankpins at the rear albeit in a modifified form on the centre axle the thick boss was still causing issues by pushing the coupling rods in to an open-ended wedge shape. I had dismantled one side with the plan to carefully extract the crank pins and turn the bossed down on my Unimat SL. Life intervened and I bought a Unimat 3 early last week, so having collected it from Driffield on Tuesday, I did them on that instead.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"777\" height=\"802\" src=\"http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2021\/04\/IMG_0003.jpg\" alt=\"\" class=\"wp-image-4523\" srcset=\"http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2021\/04\/IMG_0003.jpg 777w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2021\/04\/IMG_0003-291x300.jpg 291w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2021\/04\/IMG_0003-768x793.jpg 768w\" sizes=\"auto, (max-width: 777px) 100vw, 777px\" \/><figcaption>GCR Class 5A Crankpin boss turned down<\/figcaption><\/figure>\n\n\n\n<p>It now runs much better on the rolling road but I am sure\nthat once I get some weight in it and on a test track it will be fine.
