I'm going to save the best for last kind of guy so in my perfect world I'd be showing you guys the coolest parts at the end of the video like the laser cutter but I want this video to be sort of a start-to-finish journey of the of the birth of the new case for my personal rig so we're going to go completely in order all the way through the bending and and the and the cutting until we arrive here freshbooks is the super simple invoicing solution that lets you get organized save time and get paid faster check out the link in the video description to try it for free alright so this machine you're looking at right now is a 2.5 kilowatt yes that is 2,500 watts carbon dioxide laser worth about a million Canadian rupees it concentrates all of that power on a spot about seven one thousandth of an inch in diameter giving it an energy density greater than the Sun and allowing it to vaporize up to 200 inches per minute of 20 gauge cold rolled steel as you watch the laser start a new cut you'll see an initial flash where the plasma goes flying up as the beam hits the top of the metal then you'll see sparks on the bottom from the inert assist gas protocol e makes their own on-site with a nitrogen generator blowing it down towards the grate which holds the metal in place during the cutting process so the machine you're looking at right now is purely digitally controlled and has been running about 18 hours a day since 2008 with only about 5 days of downtime the next stage is deburring for small parts that would otherwise fall through the grate and get lost in the cutter there's little tabs to hold them in place that need to be manually removed but all of the parts do actually get Deibert anyway because while in a perfect world little bits of melted metal would not cling to the finished parts because the laser has to slow down going into the corners of a cut power needs to be dropped appropriately or the size of the cut will change and co2 lasers don't respond as fast as the machine needs to move so power control on the corners is imperfect so for that reason two sets of rotary brushes are used first a high abrasion one to eliminate what they call dragon's teeth and slag with a less aggressive one to round the extremely sharp corners that would otherwise slice up your hands fun fact the two sets of brushes that are used oscillate back and forth by at least one brush radius this ensures that every edge is hit equally from all sides and gives the bare-metal a uniform finish for applications where it won't be painted next is countersinking where our very small project was run on a drill press with a spring-loaded depth stop device to ensure that all the screws are perfectly flush but for larger projects there's actually a CNC router table that does this automatically next is the part where we all do the bender bender ah dude oh I fell off my box anyway um anyway no actually this is the part where the metal gets bent proto case performs their bends on a press break with a punch and die system that's designed for airbending where the punch the ground hardened steel piece beds is made to be accurate to put them about a couple thousandths of an inch pushes the metal down into the die but leaves an air gap under it this technique combined with the accuracy of the controls being used so the one you're looking at is a CNC controlled 60 ton press and extensive computer simulation of metal bending to compensate for spring back and metals propensity to stretch better than it compresses allows air bending to be very versatile and accurate without the same operator skill requirement as bottom bending where the punch bottoms out into the bottom of the die at the next stage pens or cell flinching fasteners if you're one of those people that actually calls things self-adhesive bandage or facial tissue instead of band-aid or Kleenex and these are standoff stands and nuts that are inserted by a press that applies six tons of force to permanently fasten them to the metal fun fact the press doesn't apply its force until it's about a fingernails width from the workpiece to prevent operators from crushing their fingers when it comes to welding there is no single way to do it but proto case uses gear from an Australian company called fro Gnaeus that helps to alleviate some of the shoes with using more traditional MIG and TIG welding techniques like the tendency for example of thin sheet metal to get wavy or even melt back from the attempt to join leaving two ugly pieces of metal and a gap in between instead of a joint it actually bears a lot of similarity to MIG welding where a spool of wire is being constantly fed towards the joint filling much the same role as solder wood and soldering except that the difference with fergus's technique is that thanks to digital control of power and the spool feed rate the filler metal is actually repeatedly heated and applied 20 to 30 times per second rather than constantly this results in cleaner work lower power consumption and less heat being applied to the workpiece so with this tech instead of being limited to working with 16 gauge aluminum or higher you can go all the way down to about the thickness of a pop can the only drawback is that machines from erroneous cost about ten times there's always the gotcha isn't there router milling is used in situations where the design work is too fine to handle the heat of a laser so the setup you're looking at is a five by 10 foot table with a CNC controlled cutter very similar to a drill bit that can be controlled to within about a thousandth of an inch the coolest thing about this doodad is the automatic tool changer so more of the process is automated even if asked to make a lot of different kinds of cuts then with all the parts bent and cut it is finally time for painting almost working mistake number one with any paint job is poor preparation so the entire project gets cleaned and degreased edged with a phosphate to roughen the surface for better adhesion and in the case of steel coated with a light touch of zirconium for corrosion resistance after that all the little screw threads and anything else that would be damaged or resized out of Tolerance by getting gunked up with paint gets plugged heat-resistant masking tape is used for any areas that need to stay barrel and then the finished parts are hung up electrically conductive hooks where the powder coating powder clings to them due to static electricity yet another fun fact the nozzle of the powder coat applicator is charged at 100,000 volts to make the powder really cling to the parts so you can actually build up multiple layers of material before they're finally rolled into an oven and baked which leads us to the final stage assembly where the computer drawings are turned into a real-life object that if all goes according to plan somewhat corresponds to the original computer drawing and from first inspection I'd say this went pretty darn well I can't wait to put my liquid cooled system into this truly one-of-a-kind rackmount case so huge thanks to proto case for building it for me it is really amazing what those guys can do with custom metal fabrication speaking of amazing what if there was a desk that could be lower and then higher oh there is write-up desk comm the providers of the desks that we use here in our editing den benchmarking room and in my office they're fantastic because not only do they allow any individual user to get it customized to exactly the right height for their their best comfort while they're working they are also quickly and easily adjustable so you can go okay I want to be sitting right now oh you know what I'd rather kind of stretch out my back a little bit and step work standing up for a little while no problem we've got presets all you do is hold the button and boom it goes to exactly the setting that you set with the preset we've got a variety of different table tops everything from corner desks two large straight desks two smaller straight desks they've got a lot of different surface coverings that they can do and a little bird told me that if you contact them directly they can even work on custom sizes of tabletops as well so check it out over at updesk dot-com slash Lynas linked in the video description if you've been thinking to yourself gee I sure would like a standing desk one that's well-built high-quality and all that good stuff so thanks for watching guys if this video sucked you know what to do but if it was awesome get subscribed hit that like button or even consider supporting us directly by using our affiliate code to shop at Amazon structions for which are up here buying a cool shirt like this one or even with a direct monthly contribution through our community forum you get a cool little contributor badge so now that you're done doing all of that stuff you're probably wondering what should I watch next so click that little video on the top right corner to check out our channel super fun video with a Christmas relay race should be pretty good
