Late Nights Engineering Unusual Hood Hinges | BANKS BUILT Ep 26
this is the last week before lockjaw heads out for sheet metal work the guys rush to get all mock-up pieces fabricated and installed built protected by amsoil with support from roadster shop and nitto okay so all right guys exciting moment today matt and i have been finalizing the mock-up hood hinges that we've got here super beefy in quarter inch plate but in this configuration they're kind of loose useless they're sloppy and we need to hold these two mounting points to each other so that's where this guy comes in i just finished tacking up this bracket and it uses two existing bolt holes on the core support there's more we're going to drill it later but this thing is essentially ready for test fit so i see matt over there going through the list and i want to test this thing i want to see these hood hinges in action all right wanna hold this for me while i do the owners yep definitely let's put this guy down here all right i'm really i'm really excited to see this come together right now first mock-up okay so far so good let me grab the two bolts for this guy okay so it bolted up all right so i bolted it right now back up first and let's just take a look at this thing oh man that that looks so cool looks ridiculous in the best way possible all right you ready here goes how cool is that victory oh man that is awesome look at that that is so rad i want to do it yeah yeah that hard stuff worked perfectly yeah so we talked about here i'll take this guy all right we talked about keeping it from going the links from going over center yep uh this stuff's all just loose right now there's no bearings in it or anything like that not even washers yeah it's thrown together i was too excited we didn't wash it tighten it but to keep to keep this link and this link from from going over center or this way at this point i use the geometry and just let it lock itself into place so it's got a built-in stop to it yeah I'm glad that's pretty awesome I'm glad we added those extra bolts i mean it's all hand tight right now but yeah we've got some spots and we just used two of the factory holes but there's some extra um yeah those are going to come in positions that will bolt through on this thing and just once we have all the way make it beefier i get to sit here for the next few hours and just do this all right i had sweat now i have blood snow i just need like a breakdown this coming weekend no blood sweat and tears on this thing so we talked a little while back about how we're going to design a new fiat system front engine accessory drive for our l5p here because we're putting our blower on we've got our new crank pulley and we're going to kind of position everything down low on lockjaw here and this is just for mock-up so that we can go off to sheet metal and have all this stuff in the location it's going to be in when we actually build the final engine so alternator vintage air sent us a mini sand and air compressor so that's mounted down here the suction and discharge are popping out the side here so we should be able to route that nicely around here and probably hide it within the sheet metal work so there we go mocked up front engine accessory drive with our hood hinges mounted now there's there's a decent amount of weight hanging off this core support we can't fit the factory inner fenders which come over and gap this core support from the firewall and hold it in position so we're actually contacting our tire right now which isn't good no not what we want so we got to find a solution for that and these hood hinges are going to hang that hood a lot of weight out here so it's going to you can you're gonna want to pull the other way then and those fenders are only gonna the fenders and the inner tubs are you know those are 19 gauge 16 gauge they're i mean they're not made to be a structural member between the two they'll certainly help yeah they'll hold the position but i will still probably get a little bit of deflection or a lot of deflection depending on you know how the hood sits out here yeah so we need you know so the best thing to do is to add something in here exactly to to stiffen this whole setup so we made a couple mock-up pieces on the plasma cutter so we yeah we put it back at droop put the inner fenders back in to grab our reference measurements for measurements let's see where you know where the core sport should land and started talking through our design for our own core support spreaders i guess we could call it yeah yeah yeah so now with these in here you know we're gonna we're gonna build some more permanent solution to this uh which you know when it goes to sheet metal Sean may or may not use those but for now for us it's going to get everything short up right where we want it to be and it's going to help me and cad as i design our air filter boxes so that i know I'm getting things into the right spot and now when we close this hood hinge with the support braces in i can get my hand under there we have gap that we need we've got clearance we're fully slammed right now so next thing we got to do make some that don't do that yeah that's actually not bad that's not bad at all hard cut to me grinding again for the seventh time this week go all now so we've got the main structure of our design for the uh fender spreader our sorry core support spreaders here so there's gonna end up being two of these per side uh and then we've got our cab side bracket which can land up here our hinge side bracket which is going to overlay on our uh reverse hinge bracket that lands on the core support that we're going to sandwich in front of that and then the piece that i have yet to cut is going to be a piece of 14 gauge overlay that i'm going to end up laying across the top this entire thing while that entire seam and blended out so it'll be a nice organic tubular looking structure that'll be uh really stiff and removable I'm gonna get my fingers cinched off here Erik just finished tacking up the firewall and at the core support here and to give it torsional rigidity what we're gonna do is we're gonna cap this piece now with with a little bit thinner metal the beauty of 14 gauge is it's a 75 thou i think nominal so it's still thin enough to manipulate but a little bit thicker than say 16 or 18 to where we'll get a little extra rigidity out of it we built these to fit some of our pre-made fixture tooling so we have a set width that we're shooting for and we're cutting the piece to still have a little bit of material thickness to go and capture a weld and one thing i have to look out for here is it's it's very easy to go off course off the start so you know if these first few tacks are a bit off all of a sudden my overlay is just going to start shooting off to the side if i do it right it'll slowly pull itself in as i tack it and i'll tack as i go and kind of push down tack push down attack and follow this contour and then once it's all tacked up i'll be able to either in position or put it on the fixture table go and weld that entire joint and blend it out and act like you know or pretend that this is a nice organic piece of tubular work when really it's three gorgeous rigid nicely done wait i think we got one last step on this though we do those are heavy so yeah and let's let's arrow both of them both bags so we can slam it yep all right let's lay out the rear first okay how's it how's it look so far uh well I'm not i can't even look yet it's too much ready yep are you kidding me let's say our get our estimations worked here we go all right let's just pop on two air filters and run it like that right that was a lot of extra work that we didn't plan on but i'm really glad we did it that that really shored up this whole front of the truck mounted the hinges really well it would have had to happen once we do the whole hood and we realized how much it was going to deflect off the core support we would have had to do something nice work Erik you as well all right so i just finished getting this laid out with matt I've got all these pieces corresponding to each other so now I'm going to take this get it tacked up and either bring that to the hood or bring the hood over to me set it up make sure everything looks good before i do any stitch welding or welding at all and I'm hoping pretty soon here we'll have a hood that opens backwards so i got some work to do all right you ready yeah crazy uh crazy hood hinges need crazy brackets so that's the first time this is going on it worked in the computer so it's guaranteed to work here our bolt spacing is okay here we go it will bolt on step two will it fit the hood all right moment of truth here no way oh yeah look at that oh yeah oh my god it's perfect no way that is awesome one two three four now we gotta yeah i mean we're halfway there but we're gonna make the other one we know it works i just uh i just mirrored it in the computer then we're good yeah so that's what they do at the factory right they just build half and they mirror it yeah okay so you can just mirror this real quick we're good oh that's so cool i'm going to weld the net to the back side of the doubler this is an existing hole for the original hood hinges and then what I'm really excited for is putting this thing onto the hinges and seeing how it moves all right time to weld some really old steel how did i get the crappy job all right that's the last one that means we can bolt these both up and uh throw this hood on once and for all all right stiff as hell initial mock-up went really well on these they fit freaking awesome um so now we're gonna pull them back off so Erik can weld some studs on the backside which will make it quite a bit easier as we put the hood up onto the hood hinges with the stud poking through and we can pop them into the hood hinges and put some nuts on looks good that's gonna work yeah see if my notches aren't lined up on something I'm never gonna see again that is just unacceptable okay which but it's here it's in here you'll know oh oh no i don't forget damn it show time there we go both sides done time to put them on the hood we'll put that on the truck with the hood on the truck that's what i want to do that's really not a great thing to hit on my hand kind of feels too sick a mechanical hitting device right there i i shouldn't have seen it or anything it's not a bright color yeah that's when i start calling all my dead blows and hammers mechanical hitting device yeah I'd much prefer that technical term it sounds better it's like if Jeremy Clarkson was an engineer i guess we could even go one step further and call it a mechanical impact who designed this should we get our shop boy to help us yeah so brackets are on uh this this is it this is a moment of truth we are gonna put this on the hinges right now and we're gonna see if it fits and once it's on the hinges we can check the hinges out and see if it closes tune in next week all right let's do this this isn't awkward yeah we're gonna like tuck it up into the yeah here we go hold on you're almost done this one's in this guy's in damage oh man down never whatever i get a nut on what do you expect out of an intern all right that is one reverse opening hood on lockjaw oh my god you ready we'll see what happens we're gonna see one two three oh wow that's like really smooth all right of course there's no there's no cowl piece but yeah look look at that gap that that is spot on that is awesome so we've got we've got three three planes of adjustment that we have to worry about with the hood uh we've got our our four and a half we've got our side to side and then we've got our up and down so our four and a half is taken care of in the the angle bracket we've got slots in there our side to side is taken care of in those starfish that are on the underside of the hood and then our up and down is going to be in this bracket here uh mounted to the core support so we got a little bit of adjustment to do to get all the body panels to line up nicely but all in all let's open it up this is awesome yeah you did a nice job nice job they didn't give me a microphone nice job buddy he's about to kiss you i didn't really have to support it at all this time following the spring is going to be perfect yeah we're going to get a spring on this thing that's going to help assist in the in the initial opening and then as it comes over the top it's going to slow it down so that it doesn't we've got our stops on here mechanical stops built into the springs but we don't want it to just smack into those when it opens so an over center spring it's actually going to going to dip across center line so it's going to help you open it and it's going to help catch it on the way down that's a sick Volkswagen beetle dude that's so cool what was that Lamborghini panda wagon it looks like i think Gales pretty happy about that hood in the next episode lockjaw heads to empire fabrication for some sheet metal work you
