hi welcome back to zack of all trades I'm Zack and today I'm going to be building the Gothic arches for our little $500 shed house the first move is to put down some shoes here because I'm gonna build these art on a jig they're gonna be lots of interruptions because I have help since I have four foot sheets here and I'm gonna be building something thirteen feet tall but I'm here I'm gonna use some spacers some pieces of siding and because somebody's gonna ask where somebody will ask I would what am i doing in a basement how do I have a house to to work in the place where I'm working here is the basement of some family who is who is building a house pretty near our property so I have the luxury having a pretty good pretty good workspace here which is really nice very cool that be able to have yeah so now I have know about mmm about 13 and a half feet or so of death and I've got 8 foot wide so what I'm gonna be making is 13 foot by 7 a half feet wide and I've got a corner back there that corner is gonna be really handy for this whole bending bowing thing I'm gonna do a little measuring here I'm measuring its marking 13 feet which is gonna be the top ultimate top of this thing market here do it again over here now I've made these marks I'm gonna measure seven and a half feet don't think that it's gonna be an issue because these sheets or heavy enough but just in case the just in case the plywood bow tries to stretch these guys out I'm gonna go a little strips here in order to hold them all together now I'm going to screw some blocks down here at the corner and now we'll see if this is gonna work like I think it is the corner with this guy into the other corner with the other end that seemed to work now down here at the bottom in I'm gonna go ahead and take a chunk just a small chunk of 2x4 and I'm gonna screw it down right here because ultimately my baseplate my frame really is gonna be 2x4 so I want that to fit right into there so I'll go ahead and screw this guy in here I'm also gonna screw down a couple of blocks on the outside here and here I've seen in a lot of other people's iterations of this project a lot of blocks you know like 15 or 20 blocks following the whole contour of this and in my opinion I don't think that you're gonna get that much I don't know miss shapen this when you're when you're bending just this much here so I'm just gonna put down two on the outside then I will go ahead and put my four inch spacers my four inch blocks which are going to be dispersed throughout the whole thing and then I can go ahead and put the next one in there with these just temporarily kind of in the way to make up whatever that space is going to be and then I'll put the blocks on the inside the jig blocks on the inside to hold it all in place and then I think I'll be about ready just using this jig quickly this is not what I had hoped for we will talk more about this later but in the meantime since I have a whole bunch more of them let's try another one now I went ahead and marked out 18 inch spacing just kind of arbitrarily and I wanted to start it at the center of this joint right here I want to have I want to have one piece of support evenly on either side of that joint just to shore it up a little bit just to make a little bit stronger and last lastly I have a piece of 3/4 inch plywood that's going underneath there just as a spacer while I'm screwing these down so that so that the the two-by-four chunks will be right in the center of these 3-inch strips here so let's get Rocking shall we and now as some of you probably realized before I did I've discovered the problem with using this corner back here I'm not gonna be able to get my drill back in there to to screw into the backside of this block I think it'll all hold together enough to pull it out of the out of the thing pull it out of the jig and screw it in outside of it I hope that's true sheesh so if you're doing this maybe backing yourself into this corner isn't the best idea learn from my mistake okay let's pull it out of the jig and see if it holds its shape or if it springs cool I think it sprung just a little bit but I don't think it's enough to be a problem I'm gonna get this guy together okay just nine more to make nothing to it now that I've finally finished building all of these blasted things I have a few observations that will help you should you decide to undertake a project such as this first things first plywood yeah there's lots of varying grades of plywood and I would highly recommend being pretty selective about your plywood I just grabbed regular old three-quarter inch Ono sheathing a grade plywood in order to do this because that got me the best price and that's what they had something that I had not taken into account with this plywood I don't know if you can see this let's do this how about right there can you see me through those gaps yeah there you can look at that so gaps as many of you carpenters know in regular old plywood there's gaps well that's a problem when you go to bending plywood because while some of it bent very nicely and gave me no troubles something like I don't know 15 of them or so did this when I bent them now that brings me to my next thing I made some comment about how many people put way too many blocks in their jig and I only put two plus the ends I think I then figure this out until way too late but I think that even with this subpar plywood and I had jigs with that many blocks on it or a jig with that many blocks on it that those blocks spread out that pressure that tension and I think that I probably wouldn't have broken so many of these so what that'd be a I don't know a lesson I guess put more blocks on your jig it'll help and what was the other thing oh yeah so the the whole backing yourself into a corner and and then pulling the pulling the bows off of the jig then screwing in the outer side to the blocks changes the angle of the dangle a little bit on the on the base of the of the bow some of you probably figured that out and probably said that to your computer screen but I wound up after I figured that out I wound up taking a clamp I had one clamp in the truck for changing brakes I wound up taking a clamp and clamping that that bass end together so that I could get the whole thing out of the jig and then put the put the screws into the outside of it so I think that's it so now I've done a full-scale mock-up with the base of the bows 15 feet apart like it's going to be and i mocked it up up here a broken piece of plywood is to make the impression of a ridge pole a ridge beam whatever you want to call it so now that I've got all that mocked up I've measured here from here to here on this bottom one because as you see both of the bottom bottom strips are too long now so I've got three six and three-quarter inch right here and now I'm gonna cut them all off at six and three-quarter inch and then should be pretty well ready to rock amazing isn't it how quiet a skill saw is when you don't turn on the mic yeah drills are pretty quiet too but let me tell you what I'm doing here anyway I have this little board that I'm gonna screw in as a gusset of sorts to hold the top end of this thing together and the thing that I didn't show in the video earlier is that those top blocks those top two by four blocks I've doubled them up so that the surface that I'm drilling into are screwing into right now is actually flush with the front surface of the strips let's give it a try shall we see how it looks standing up oh yeah that looks dandy done it yeah I think that'll do here look back at the camera so you can get a good thumbnail shot go ahead oh no what do i do do I catch it in do I not oh I can say it was beneficial to not have the mic turned on for that one let me show you what happened here look at that little board right there my gusset that's where it broke when that torsion hit it just that little gusset broke rather than any of the rest of the pieces to this which speaks somewhat to its inherent strength and blind sheer dumb luck well that's pretty much going to do it for today only thing that's left is to carry these guys out to the site I really hope you enjoyed it if you did I imagine I'll be seeing you again real soon if you didn't thanks for stopping by either way thanks for watching take care
