How to make a tablet press part 2
Installing the base plates
Winding, just getting everything ready to be lined up. Okay, so the next thing that we're going to insert is the base plate. If you've got a TDP punch die from LFA tablet presses, now would be the time to change the center section. You do this quite simply by removing this front rod. So I'm just going to get the bolts to do this, and then we're going to do that. Okay, the next thing that we have to do is insert the base plate. I find that the best way to make sure that it's sitting in exactly the right place, is to roll up the punch die a little higher than you would normally have it. So just loosen off the sides here. As I said, we're going to be doing a lot of fiddling and adjusting with these over the next while, so it's good to have them relatively free and easy. So if you just do that, and then tighten it back up again. Once you've got that in place, just roll it through the motions just to make sure that the upper pin is coming down into it as well. Just want to make sure that it's properly lined up.
Before tightening up the bolts on the bottom, by making sure that both the top and the bottom die align with the centre ring in side the base plate. This ensures us that when we come to actually turn on the machine, that center section is bang smack in the right place. This will avoid any damage happening to your punch die. If it is not aligned correctly you will likely chip a part of the top die. So this comes highly recommended.
There are two access points for the nuts, one on either side. So if you just get on them. I've said with other parts of this, it's probably not worth tightening it up straight away. On this part, definitely is worth getting it in there and just getting it absolutely solid. Sometimes if you're having trouble changing a die, it can be worth stripping the machine back just this far, just to get the dies in and out. I mean, there is a video that we've also done, showing you how to change dies without taking it quite this far. So that might be worth checking out as well, if that's what you've got planned in.
First things first, let's just get this absolutely tightened up. So really do make sure that that plate's on and solid, and then once that's done, you can tighten in this front rod. It's also worth getting that one in nice and tight, nice and early. Get this front rod in nice and tight.
Always do a full cycle before turning on the machine
Next, just move it through the motions. Perfect. Now, obviously, our ejection height is completely off. The next thing that we're going to do is continue on up the machine so that we can actually have a tdp 5 flywheel to work with, so we don't have to keep turning the greasy rods by hand. So if you join us at the flywheel section.
Okay, so the next thing that we need to do after doing the upper and lower drift pin assembly, is we need to come around to the side, and we need to install the filling mechanism. So we're on the right-hand side of the machine right now, and the first thing that we're going to do, is we're going to pop in the supportive block that holds the hull of the mechanism. That comes with three Allen key bolt/screws that are gonna need to be tightened into place. And as I said before, all of the parts will come with the bolts closely attached to it. So you'll know exactly which ones you're going to be using for which holes, otherwise it could get a little bit confusing. It's impossible to get this on upside down or back to front, so just whack it in the way that it comes.
This bit, you want to tighten up nice and tight from the start, whereas we left all of the upper and lower pin drift assembly loose so that we could get back to it later and adjust it all up nice and neat. This bit here is going on and staying on. Once that's nice and securely on, the next thing that you want to do is take this little timing bar, just pop it in somewhere. It's definitely not on this side of the mechanism. It's on this side of the mechanism just here, so don't try and pop it in on the wrong place. On the little bolt that supports it, you'll be able to see a little dimple. This has to be facing towards the front of the machine, because as you can see, just here on the side, there's a little Allen key bolt that goes into the metal, which you actually have to tighten up to secure it into place.
Once I've found the right size Allen key for that. Here it is in my collection. Make sure you get in there and get that bit tightened up, otherwise it's going to be difficult when you come to turning your machine on. You'll just see it pull tight into it.
You want to leave the bolt out a little way, this bolt out a little way - I did just tighten it a bit too tight - just so that it can move freely, because you don't want it catching or chumming up. Just pop that in like that so it's got a little bit of movement in it. It's absolutely perfect. If we adjust the camera down a little so you get a better angle on it. Just there onto the bottom, goes your filling boot. And we'll now move the camera around to the front so that you can see how we secure in the TDP 5 filling boot.
