Install the Upper and Lower Drift Pin Assemblies
So the first thing that we're going to do is we're going to install the drift pin assemblies. When we send you the machine in parts, it will come with all of the parts with the bolts sitting inside the holes that they need to go into when the machine is assembled. The entirety of the lower drift pin assembly and the entirety of the upper drift pin assembly would be inside different bags, just so that it makes it very easy. They'll also be labelled up, just so it makes it very easy for the reassembly. So if you come a little bit closer to the machine, we're going to do the first bit.
So the first thing we're going to do is we're going to insert the upper drift pin assembly and if you start by popping on the upper locking nut. There we go. Just get that properly on there. And if you get it a little way up, that will really keep it out of the way for the next thing that we have to do. And then if you rotate the cam around a little, we'll just slide that whole bolt section. One second, it needs to be a little bit higher. Rotate the cam around a little. What you'll need to do is you'll have to make sure that it's like that. You rotate it around to the right position. It should just sit nicely above the hole.
And then if you pop the upper pin drift assembly in through the very, very bottom of the machine. So up through here, and guide it up through this hole. It's by far the easiest way to get it in. And then up in through the upper pin drift assembly guidance section, just here. It's a metal plate at the top. And then the cam might not be perfectly in position, so if you just give it a little wiggle until it wants to take to that nut. And there we go, perfect. We have got it on, so to speak. Then you can just bring that nut down a little. If we move it all up out of the way actually, for the time being, we can adjust it all up towards the end. But if we just get it up and out of the way right now, that will make it easier for getting on the lower drift pin assembly, which is what we're going to do next.
So we're back at the machine and we're going to install the lower drift pin, but before we do that, we have to install the arm that controls and guides the ejection height and the fill depth. That arm will come in a plastic bag with two nuts, two identical nuts. And the first thing that you have to do is you have to attach one of the nuts onto this little side arm here and spin it all the way up, all the way up, all the way up. Then you have to pop on this middle section and then attach the other bolt from underneath. As I've said a few times, I wouldn't bother tightening everything up just yet, because it's all going to need tweaking and adjustments and we'll do that right towards the end.
The next thing to do is to insert the lower drift pin. As you insert the lower drift pin, you need to have one of these cogs ready, these adjustment nuts ready so that you can pop it in in this section just in here. And also have the other one to hand because it goes in here and this lower drift pin needs to thread through both of them. It doesn't matter which way around they go then. So if we tilt the machine, it's probably best if you have someone to help you with this, because it can be a little bit fiddly.
Get the first one in there, just spin it down a little. Get the second one over the top, continue to spin down the first one. Then once you've got that first one in properly, just get in this second one. If you have bought TDP punch dies from LFA Tablet Presses before, now would be the absolutely perfect time to change them, or maybe before you even put in the TDP 5 lower drift pin assembly. All right, can we rock that back to flat? And it just saves you having to fiddle around at a later point.
The next thing we're going to insert is the nut that holds in the lower die. So you've changed over your dies. As I said, now would be the perfect time to do it. And then after that, just the side section that holds these two nuts in place. And if I find it using my finger first, I often find that can be quite helpful. Just needs to be a little bit higher than I first anticipated, but there is that little side nut. So let's pop on the little bar that holds everything in position. As I said, it's not worth tightening it up really just yet with a proper Allen key, because we're just lining everything up for the time being, just getting everything ready to be lined up. So the next thing that we're going to insert is the plates.
