I ordered a 3.5mm boring tool and when it arrived, I\nthought I would have a go. <\/p>\n\n\n\n<p>I cut a length of brass rod and turned a section of it down\nto the required width and then drilled progressively bigger holes in the end\nuntil I reached 5mm in diameter. Then I tried the boring tool ad had a gotcha\nmoment. The tool might be 3.5mm wide but it\u2019s also 3.5mm deep and it wouldn\u2019t\nfit when trying to centre it in the hole for cutting\u2026. In order to get the tool\nin I would need a bigger hole than I wanted. <\/p>\n\n\n\n<p>I scratched my head for a bit and then had a rummage thought the box of tools that came with the lathe. One of them had been ground with boring holes in mind but the corner of the cutting edge was chipped so while it would cut, I didn\u2019t get a square edge to the bottom of the hole.<\/p>\n\n\n\n<p>It was at this point that I remembered that I had bought a\nmini bench grinder from Lidl about 3 years ago and it was sat on a shelf under\nmy bench. <\/p>\n\n\n\n<p>Out it came and I had my first go at grinding a cutting tool\nfor the lathe. Light touches soon restored the missing bit of tip and I now see\nwhat Ian meant when he said a sharp tool makes a lot of difference to how it cuts.<\/p>\n\n\n\n<p>While I had it on the bench, I reground a couple more tools\nthat had dings out of the edges too.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"861\" src=\"http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2021\/05\/IMG_0002-1024x861.jpg\" alt=\"\" class=\"wp-image-4582\" srcset=\"http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2021\/05\/IMG_0002-1024x861.jpg 1024w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2021\/05\/IMG_0002-300x252.jpg 300w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2021\/05\/IMG_0002-768x646.jpg 768w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2021\/05\/IMG_0002-357x300.jpg 357w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2021\/05\/IMG_0002.jpg 1201w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption>Front Windows<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"743\" src=\"http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2021\/05\/IMG_0004-1024x743.jpg\" alt=\"\" class=\"wp-image-4583\" srcset=\"http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2021\/05\/IMG_0004-1024x743.jpg 1024w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2021\/05\/IMG_0004-300x218.jpg 300w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2021\/05\/IMG_0004-768x557.jpg 768w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2021\/05\/IMG_0004-413x300.jpg 413w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2021\/05\/IMG_0004.jpg 1280w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption>Front Windows with 5p<\/figcaption><\/figure>\n\n\n\n<p>And one with the obligatory 5p for scale.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I had some Milliput out for making some modifications to some axlebox ready to make some castings of them.
