Just a little back, I found some MTL Interactive padlock cylinders on eBay rather cheap, and with no use for them other than picking them, purchased a handful. Once they arrived, of course I picked them all a couple of times over a few days, then set them down and wondered if I could make use of any of them. I didnt have a pile of MTL padlock bodies lying around sans cylinder, but I did have a pile of Lockwood 234's and 334's. I took a quick look and ascertained that although close, the body was not quite big enough for them, so I packed them in their bag, and put them in my collection box. Not long after, I was browsing Noctis's Youtube Channel and seen that the bugger had already done it!
After a brief watch of the video, I decided I wanted to convert one of my Lockwoods as well. I did one of the 334's and with a little effort, it fit and worke beautifully, upgrading a nice medium security padlock that I have a lot of, to a excellent high security padlock that I had none of! Of course, once I had done one I started looking at all my other Lockwoods, and decided to modify my 290S84 shutter lock as well. I figured that you guys might like it, so I took a few photos of it afterwards.
First of all, the body is a little too small as I mentioned above, when I measured, it was .0005" thou different. Not much! I used a small sanding wheel on my dremel to open up the body, unlike Noctis, who did the inverse, and sanded down the cylinder. Either way will work.
Next, I set about modifying the bible, in order for it to fit into the other part of the Lockwood IC assy. Take a little off the front and a bit more off the back, being careful not to cut or file into any of the chambers. I was moving a bit fast on my first go and ruined a cylinder by doing exactly this. When you are finished, it should look a little like this.
Next, I had to find a tailpiece that would operate the lock in the correct fashion, as the original was oriented 90deg differently from the Lockwood. I got lucky on this step, and found one that fitted the bill amongst my parts, I think it may have originally been in a BiLock padlock? Either way, it pays to hoard
Lastly, I put it all back together! I had to adjust / sand a little more out of the body, but other than that, the cylinder fits and works a treat. Oh, and it looks super cool with all its chrome
Now, the thing is, I still have a whole lot of Lockwood padlock bodies, and only a few more cylinders, so I can't possibly use them all. I know that quite a few of you guys also bought the cylinders, so I was thinking I would be happy to send anyone a body if you wish to do the same, for the price of the postage to wherever you may be. I'm located in Western Australia, and for a rough guide, sending the body to the US would set me back about $10 AUD. If you want one, hit me up with a PM and Ill get it done for you, and when you build it, post a pic here so we can all cop a look!

You motivated me to get off my lazy hindside and do something with one of those inexpensive MTL cores and a Lockwood body. I did file down the KIK cylinder diameter just because it would allow the core to be moved to another padlock if I decided to do so in the future. And did, of course, shorten the bible on both ends. (Sorry, no more Genesis or Revelations).
