为我姐姐的婚礼招待会伸缩谷仓枝形吊灯

I was really excited my sister asked if she could have her wedding reception in my barn. I had a couple ideas of things I wanted to do to the barn before the wedding, the biggest of which was a rustic chandelier hanging over the dance floor. But I didn’t want to take away anything from the space as a workshop, so I decided to make the chandelier retractable, allowing the chandelier to be raised up out of the way into the rafters.

我已经恢复的谷仓是由8“×8”wooden beams, constructed using mortise and tenon joints. I had a couple of these beams left over, which I thought would work really well for the chandelier.

One of the ends still had the tenon joint, and instead of cutting it off, I decided to cut the other ends to match. I Thought it was sort of an homage to the construction of the rest of the barn. I used the Skillsaw to cut as much as I could, and then used the Sawzall to finish it off. I also drilled dowel holes to match. I notched out the centers of the beams so they could overlap each other in a lap joint. After setting the depth stop, I used the miter saw to make these cuts, and then used the backside of my claw hammer to knock it out. (Ya, a chisel probably would have been better, should probably get one of those one day, haha). Set them over the top of each other.

I wanted to use one large 1 ½” bolt through the middle of both to secure them. I was nervous to drill this hole by hand though, because I was sure I would get the hole crooked. But the drill press didn’t have enough reach to make it to the center of the beams. The only other thing I could figure to do was clamp down a piece of plate and then use my mag drill to bore through it.

Instead of just using a large washer on the bolt, I drew and cut out some decorative brackets on the CNC plasma table. Before I had the CNC table, I did countless cuts like this using printed stencils and a handheld plasma torch. This is 3/16” mild steel plate. I got the matching brackets bolted on the top and bottom and tightened down the 1 ½” bolt. Had to use pipe wrenches to tighten it because I didn’t have any other wrenches big enough.

I also cut some brackets for the ends of the chandelier, which the support chains will attach to. I made the tabs for the chain attachment slotted, thinking that if the chandelier didn’t hang flat because it was heavier on one side than the other, I could adjust it here hopefully. I cut these brackets out of ⅛” hot rolled sheet metal. I also used 1 ½” lags screwed into the wooden beams to keep these brackets from sliding inward when it’s hung.

我在镇上买了一些连锁店，但是当我回到家时，我决定我不想用它，因为它很有光泽，并与枝形吊灯的其余部分形成鲜明对比。相反，我决定从⅜“板块中剪掉自己的链条。我无法削减完整的循环，因为我当然无法组装它，但我应该这些“S”形状应该锁定在一起，对100-200磅的枝形吊灯仍然足够强大。我还剪了顶部支架，即使用氧 - 乙炔火炬将连接到并加热并加热并弯曲它的侧面。所有人都抱了起来！只是用绳子暂时保持它。当他们在谷仓里达到顶峰时，我有几个家庭成员的担忧，以检查我的进步，并以为我将用一些小绳子，哈哈挂着枝形吊灯

我开始接线。我使用了长¼“钻头钻通过8”的光束。我偏离了洞，交替的侧面，认为它看起来比沿着光束中心沿着灯泡运行更好。

我买了几个灯具（我认为它们被称为蜘蛛吊灯？）只适用于电线和插座，因为它实际上比购买电线和插座的短管轴，并自己接线。我将电线切割在顶篷下方，并将其扔进金属废料箱中。我在梁的下侧放置了电线应变消除，在设置电灯泡的高度之后，然后在向上拉动以保持紧密的同时将另一个拧紧。

Wire management time. I used lots of wire staples to keep things as organized as possible. Had to use two electrical boxes to fit all the wire connections. I picked up some heavy duty 12 ga rubber coated wire that will supply the power to the chandelier. Testing out the bulbs for the first time! I bought edison bulbs, which I thought would look cool for this because they put out a nice warm color and you can see the elements inside. All 26 of the bulbs, I was happy.

随着枝形吊灯完成，我搬到了卷轴上，将升级和降低它。我想一个大，重，简单，工业的轮子是票。我花了一些时间在Sketchup中设计，然后在Illustrator中重新拧D形状，为CNC表创建GCode。插画家使用vector，它创造了更平滑的弧。另一方面，Sketchup使用线段制作曲线，即使电脑屏幕上的平滑曲线也看起来像是更加锯齿的曲线。

我希望卷轴为5英尺，必须切成2件。我从本地废料院子里拿起这个⅜“板。我真的很高兴找到它，因为大约是购买金属的一半。得到双面切割并将它们放在焊接台上。我把它们夹住并焊接它们。我焊接一侧，将焊接光滑与角磨机接地，将其翻转过，再次夹紧，然后焊接后侧。

我以为1“钢筋在卷轴外面弯曲的弯腰会用作一个手柄，因为钢筋抓住很好。当我焊接它时，我用来了一个来将末端拉到一起。我剪掉了一个较小的背面，因为它唯一的目的是将电缆保持在卷轴上。我还切割了一些5“管道，电缆将在卷轴的中心包裹，并通过它的中心焊接1 7/16”轴材料。锁定机构。我在周边围绕着大量1“孔设计了卷轴，因此可以设置在不同的增量高度，然后这一英寸的轴将滑过并将其锁定到位。我焊接在一个标签上，所以我可以挂锁它，只是没有人搞乱它，意外地导致事故。

我在谷仓的阁楼区安装了卷轴。卷轴的大多数框架将被设置在墙壁中，只需几个臂突出，以握住卷轴的外部。我建立了1.5“和2”方形管，厚度的框架。我用两个轴承拧到卷轴上。我也在¼“材料上的一些角落上切割并焊接到框架中以增加一些强度。我使用½“螺栓将框架连接到8”x8“木梁它被夹在顶部和底部之间。

随着卷轴和枝形吊灯完成，最后一件事就是将一些滑轮在谷仓顶部附加到谷仓顶部，以运行电缆。绝对需要这些是坚强和安全的。有一个枯草葫芦，沿着木梁跑，峰的整个长度，我认为我可以在顶部安装一块金属通道，以支撑保持皮带轮的括号。但我不想仅靠干草葫芦梁，我认为最好也将通道绑在椽子中。

I fabricated some truss brackets out of 3/16”x2” metal strips. I drilled 3/8?” holes in these, so I can bolt them to the rafters. I cut some square tubing in half, which had the right inner diameter to fit snuggly over the hay hoist track. It was ¼” thickness. I found two old pulleys on our farm that I thought would work. I cut the pulley brackets out of ½” plate, which is probably over kill, but why not. The pulley that redirects the cable back down to the reel needed to be angled, so I heated up these brackets with the oxy acetylene torch and bent them to matching angles.

我去的梯子。我不期待这一部分。很多旅行上下。我搞砸了椽子上的一些板走路。

通道滑倒在枯嘴葫芦梁上，并用½“螺栓将其螺栓固定到位。然后我将桁架托架设置在椽子上，钻孔，并使用⅜“x2”螺栓螺栓固定。在这里安装了电源出口的枝形吊灯。然后我喂了½“缆绳上方的滑轮。我很幸运能找到我们在农场上坐在较旧的灌溉设备上的农场上使用过的电缆。然后我沿着谷仓的峰值拉动电缆，并在末端和朝向卷轴穿过第二滑轮。

我很高兴从椽子下来。这是一个夏日，谷仓的峰值必须是110度。我被污垢和汗水覆盖，我的妹妹很好，可以拍我的照片。这只是在她的婚礼前几天，我觉得她有点紧张，我可能不会及时完成它（就像我......）在快速淋浴和冲洗后，我通过卷轴的洞喂灯夹紧它。

我在卷轴上放了一堆额外的额外额外的额外额外的卷曲夹紧枝形吊灯的重量，而不仅仅是电缆夹。

一旦我觉得我在卷轴上有足够的时候，我将另一边切割成长度并将其连接到枝形吊灯上。我通过电缆上的顶针循环它通过大凸螺栓循环，以减少弯曲的严重程度，然后使用几个电缆夹。在......紧张局势建设......我不知道它有多难以升空。我对整个项目都很紧张。在卷轴的中心的管道，电缆缠绕的直径只有5英寸，卷轴直径为5英尺，所以我认为应该有很多杠杆率。如果我正在做我的数学吧，那么卷轴的一个完整的转弯应该只会提高枝形吊灯15“。但仍然，我不知道要转身有多难......它慢慢地抬起叉车，并不糟糕！它需要一点点肌肉，你绝对必须坚定地坚持它，但并不是累人升级或降低的一切。

最后我一直把枝形吊灯放在头顶上方的一只脚下，并将一个安全栏附加到电缆上，以防它留下了我。更安全，而不是抱歉。我也插入顶部的电源线上，并将一些环连接到电源，该电源将夹在电缆上，以保持它在升高和降低时组织。

我肯定会推动在婚礼前为我姐姐完成吊灯的截止日期。哈哈，我之前的一天完成了它。对于我认为的每个人来说，这对其来说有点压力。但是，就像我在婚礼上发表的演讲一样，它只是因为我希望一切都适合我的小日子。她和她的新丈夫在他们的第一次舞蹈期间看起来很棒，我很荣幸能够在我的谷仓里接待。让一个大哥自豪。
