They were not expensive \u00a38 for the set but I figure they will be good enough to work on whitemetal.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2025\/07\/Drill-Burrs.png\"><img loading=\"lazy\" decoding=\"async\" width=\"699\" height=\"582\" src=\"http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2025\/07\/Drill-Burrs.png\" alt=\"\" class=\"wp-image-7134\" srcset=\"http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2025\/07\/Drill-Burrs.png 699w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2025\/07\/Drill-Burrs-300x250.png 300w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2025\/07\/Drill-Burrs-360x300.png 360w\" sizes=\"auto, (max-width: 699px) 100vw, 699px\" \/><\/a><\/figure>\n\n\n\n<p>Once I fitted the burr in my Proxxon Mini Pillar drill I realised that with the axle guards fitted to the wagon body the chuck would hit the body stopping me from being able to drill in the correct place. At this point I had two choices I could either remove the axle guards to drill them out or make an arbor to hold the burr further away from the chuck. I chose the latter route as being the easiest.<\/p>\n\n\n\n<p>I made an arbor from a piece of 6mm rod recycled from an empty toner cartridge. Drilling a 3.25 mm hole in one end and cross drilling and tapping M3 for a couple of grub screws<\/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\/2025\/07\/1-Cutter-Arbor.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"526\" height=\"1024\" src=\"http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2025\/07\/1-Cutter-Arbor-526x1024.jpg\" alt=\"\" class=\"wp-image-7135\" srcset=\"http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2025\/07\/1-Cutter-Arbor-526x1024.jpg 526w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2025\/07\/1-Cutter-Arbor-154x300.jpg 154w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2025\/07\/1-Cutter-Arbor.jpg 658w\" sizes=\"auto, (max-width: 526px) 100vw, 526px\" \/><\/a><\/figure>\n\n\n\n<p>Then using a couple of bits of coffee stirrer to support the casting level I set up to realign the holes.<\/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\/2025\/07\/1-IMG_1624.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"570\" height=\"1024\" src=\"http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2025\/07\/1-IMG_1624-570x1024.jpg\" alt=\"\" class=\"wp-image-7136\" srcset=\"http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2025\/07\/1-IMG_1624-570x1024.jpg 570w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2025\/07\/1-IMG_1624-167x300.jpg 167w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2025\/07\/1-IMG_1624.jpg 712w\" sizes=\"auto, (max-width: 570px) 100vw, 570px\" \/><\/a><figcaption class=\"wp-element-caption\">Set up jig<\/figcaption><\/figure>\n\n\n\n<p>Using the depth stop on the mini pillar drill I was able to straighten and make the holes slightly deeper without drilling through the face of the axleboxes<\/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\/2025\/07\/1-IMG_1623.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"892\" height=\"1024\" src=\"http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2025\/07\/1-IMG_1623-892x1024.jpg\" alt=\"\" class=\"wp-image-7137\" srcset=\"http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2025\/07\/1-IMG_1623-892x1024.jpg 892w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2025\/07\/1-IMG_1623-261x300.jpg 261w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2025\/07\/1-IMG_1623-768x882.jpg 768w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2025\/07\/1-IMG_1623.jpg 1115w\" sizes=\"auto, (max-width: 892px) 100vw, 892px\" \/><\/a><figcaption class=\"wp-element-caption\">Drilling out the axleguards<\/figcaption><\/figure>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Over the last few show demos I have been slowly building a pair of Connoisseur LNER Single Bolster wagons.
