This allows you to export GCode in just a few clicks directly from BikeCAD. The time it now takes to go from a BikeCAD drawing to the actual mitered tubes is significantly reduced. I find this particularly useful for down tubes that connect to tapered headtubes or that require a lot of water bottle holes. In a couple of minutes you get a fully mitered downtube with a perfect fit at both ends and the holes drilled in all the right places and inline.<\/p>\n<p><iframe loading=\"lazy\" title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/RVZA1H-YKIA?si=tPirEgkqJFa3a-Ab\" width=\"560\" height=\"315\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><br \/>\n<!--\n<a href=\"https:\/\/www.instagram.com\/reel\/DDW-INEOXYb\/\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" class=\"aligncenter\" style=\"padding: 8px; border-style: solid; -moz-border-top-colors: none; -moz-border-right-colors: none; -moz-border-bottom-colors: none; -moz-border-left-colors: none; border-color: #dddddd #aaaaaa #aaaaaa #dddddd; border-width: 1px 2px 2px 1px; background-color: white;\" src=\"\/wpblog\/wp-content\/uploads\/2024\/12\/Insta.png\" alt=\"\" width=\"525\" \/><\/a>\n--><br \/>\nSome curious minds out there have asked me for some more details on the actual machine so here is a list of the main components I used and a video of the latest setup:<\/p>\n<ul>\n<li>The X and Z axis is provided by the Gantry of a CNC router made by Rat Rig in Portugal (<a href=\"https:\/\/ratrig.com\/cnc-kits\/routers\/stronghold-pro.html\" target=\"_blank\" rel=\"noopener\">StrongHold Pro<\/a>)<\/li>\n<li>The gantry is coupled with a lathe like bench made of Alu profiles sourced from <a href=\"http:\/\/shop.aluprofil.com\/de_DK\/shop\/Baureihe_8\/Profile_8\/\" target=\"_blank\" rel=\"noopener\">Alu Profil in Austria<\/a><\/li>\n<li>The Y axis is a made of two <a href=\"https:\/\/eur.vevor.com\/dividing-head-c_10129\/vevor-indexing-dividing-head-k11-100mm-3-jaw-chuck-tailstock-for-cnc-milling-p_010861397809\" target=\"_blank\" rel=\"noopener\">rotary chucks sourced from Vevor<\/a><\/li>\n<li>The <a href=\"https:\/\/eur.vevor.com\/other-c_11229\/4kw-er25-air-cooled-spindle-motor-and-4kw-variable-frequency-drive-inverter-vfd-p_010832703532\" target=\"_blank\" rel=\"noopener\">Spindle and the Variable Frequency Drive inverter is also from Vevor<\/a><\/li>\n<li>To control the 4 step motors I used <a href=\"https:\/\/us.openbuilds.com\/BlackBox-Motion-Control-System-X32\" target=\"_blank\" rel=\"noopener\">OpenBuilds BlackBox Motion Control System X32<\/a><\/li>\n<li>To send the GCode to the controller I used <a href=\"https:\/\/software.openbuilds.com\/\" target=\"_blank\" rel=\"noopener\">OpenBuilds Control Software<\/a><\/li>\n<li>To hold the tube on one end and keep the step motor coupled to the tube after the 1st cut, I mofified a<a href=\"https:\/\/www.forcetools-kepmar.eu\/en\/p\/exhaust-pipe-expander-tool\" target=\"_blank\" rel=\"noopener\"> Pipe\/Tube Expander<\/a> with an extended arbor<\/li>\n<li>To hold the tube in place on the other end during the 2nd cut, I modified a Pipe Cutter (replaced the cutter with a bearing: see video\/pic below)<\/li>\n<\/ul>\n<p>The main benefit of this setup is that it uses a carbide bit instead of say a laser or plasma\u00a0 and it let's you cut alu, steel, stainless and titanium without heating\/altering the tube.
