Join Paul J. Smith for an in-depth discussion in this video The spring barrel and hook, part of SketchUp Pro: Modeling a Lamp.
- [Instructor] Chapter 03_03, we're going to add the barrel and the hook to this piece, which is the small spring connection from the last exercise, and we'll just pop over to the PDF just to have a little look at what sort of sizes we're dealing with. And then we can finish this off. So this is what we're looking at doing, this hook here and the barrel. The hook's about 13.5 mm. It doesn't really matter if it's slightly off that. and it has this sort of conical top bit which is 6.0 mm. The spring really, in reality, starts from this bit, and there's a little sort of metal piece on top of that. So that's 6.0 mm up, and it is a 6.0 mm diameter, as well. Okay, so back to SketchUp, and we'll finish this off. Oh, the other thing to point out is the 52.5 mm depth of this thing here. Okay, so we're back into SketchUp. We're going to grab the circle tool. And we're going to click somewhere, and we're going to make a seven radius, seven mm radius. I've got 24 sides. I'm using Push-Pull. That's P, and it's 52.5 mm. Okay, so we're going up 52.5. Back to the circle, C on your keyboard, and hover over the edge and track into the center. And then we're going to go three mm, so three for that, okay? Now nice little trick you can do with this, if we select that inner circle, use the Move tool. That's M on the keyboard, and then we click on it. And notice we cannot pull it up, but if we use the up arrow on our keyboard, we can force it in that blue direction. Very, very simple. So different ways of doing it, Now when it comes to the bottom bit, the hook, we're going to select the base, and we're going to copy that over to there. I'm then going to use the Rotate tool. That's Q on the keyboard. so that's going to move it to the red orientation. Move over to the green direction. Forward or back, it doesn't matter. And there we can bring it around our face, the white face coming forward. Then the line tool, and just chop it off halfway. I could have used this thing, the Pie, but easiest to copy existing geometry. And E for erase, get rid of that. F on the keyboard, that's Offset, and then we can offset this in, one, enter. Couple of other things we're going to do now is just take that up to that point, so that's perpendicular. So make sure it goes magenta. And we're going to draw a line down to there, as well. Sort of chop that bit off. Another erase, E for erase. Click and hold, and trace over all these lines you don't want, so you've got that. P, Push-Pull, click, one, enter. And that's that, okay? So triple click, G or right click to create the component, and I'll call this Hook. And then Create. That's that bit done. Then move it into position, so I'm just going to grab it by its midpoint here. Come underneath and hit that point there. And then just move it in, say half a mil, so move it that direction. Okay, so now we've got the barrel with this conical shape at the top. In the next video, we shall put all this together, from the smaller spring.
