Downloaded. WOW. For the rest of you reading this: Michael has just sent me over 60 intricate photographs of various parts using his digital calipers for accurate measurements. That's over 60. Don't forget Michael, like Mark and Christian already own all the stuff the rest of us want to make from these templates, so there's no personal gain here - now that's true generosity These will be invaluable Michael. Thank you very much. Once Vern has the shop drawings for the tubes in his hands we'll be well on our way to uber accuracy As regards the T-Track: ahhh but there is a good reason to have the true measurements - I have a number of ideas/ options up my sleeve for DIY accurate T-Track so stay tuned...

Roger Roger! Sounds brilliant - PM on the way While I'm posting - re: the E-11 templates. Taking this past a Sterling through to E-11 would require accurate T-Track dimensions. I've got 10.7mm wide by 6.35mm high (1/4 inch). Can anyone confirm or correct this?

@ Vern - Re: the end cap lug. What I'll do is separate ot off on the tube template so that it can have the accurate circumference for a 42mm OD. Can you give me the dimensions for those L shaped slots? Re: the variant templates - what do you see as the difference between the template for a PVC pipe and a steel pipe? If both have the same OD couldn't the templates be the same? @ davej - that sounds awesome! It's amazing how hard it is to get. 38mm ID is not so hard but OD is almost impossible. I found a place here too but the minimum order was even more, something like ten meters. I did find a place in the UK with 38.1mm OD plastic pipe for ponds and fountains that will do a 750mm length but of course it involves importing it. It'd be great to hear what comes of your source. Maybe we could find 6 or more people and split an order? 12 people would be ideal I guess but probably unlikely. We post an interest thread on TAG maybe. Meanwhile, as an added attack, I've set my wife on the task. She's like the Internet Sherlock Holmes and can find websites for companies that don't even have websites...

It looks from the second pic like one is up and one is down... Well spotted!

That'd be brilliant! The full folding stock details and corrections are the last major hurdle left! Meanwhile today's update is the cocking handle. It can't really be templated due to it's odd size and shape but of course we need to include the dimensions within the templates document.

I don't know about Canada but I know this is the case in Australia for sure. In fact you can't even list toy guns on eBay.com.au (I tried) I have gotten toy guns through customs but they were not realistic ones and they still got opened and checked. A modded Hasbro blaster is an odd grey area. I have heard that painting them flouro colours and letting the buyer repaint them can work... I'd contact the buyer and ask him if he knows. If he bids on an item he doesn't think he can get past local customs the onus is on him.

@Lichtbringer - thanks for the offer sir. As it happens I already have the Sterling user handbook, and it has been a helpful reference but it is limited in that it doesn't include any dimensions excepting total length with and without stock folded. It's definitely the owners manual for care, operation and cleaning - understandably, not much for info on replicating. What I really need is numbers - the rest takes care of itself. @ Locitus - you're exactly right. Thanks for putting it so succinctly. Meanwhile mag housing and mag is under way. Vern is sending me some important stuff soon apparently and we should be pretty close to a complete external spec. The folding stock is now our big one, so everyone throw that info at this thread!

Matt's suggestion is a good one because other than that they are indeed made by the member in some sort of editing program like photoshop. Once you've made your sig (however that may be) you can upload it using your personal settings. Hope this helps

Here's how I see it: As with the tube templates I will create and release the full templates, once finished, for genuine 38mm Sterling dimensions. I will not make functional MYO sub machine gun templates. This is a prop replica nothing more. The dimensions and appearance will be accurate to a real Sterling but it will unequivocally be a prop. I intend the stock to function and the cocking lever to pull back, nothing more. There will be SEPERATE 40mm tube based booklet (the sights, blowback shields and muzzle need changing to fit) due to popular demand. You can see clearly by my tube templates that I have made two completely separate templates for people to choose from. I have also stated unequivocally that this an open source community project. All PDf's remain vector editable for any correction anyone can see need making. Alternatively if you see a differentiation between your real sterling and the measurements posted here I encourage you to post corrected measurements. I am creating the artwork primarily from the hard work of Mark and Christian. I have no access to a real Sterling and not only encourage but actively seek help from anyone in possession of a real one or plans for a real one that can ensure the accuracy of the dimensions. In addition to asking for any corrections that anyone sees need making on what I have posted so far I ask that anyone who can, provide the following: Accurate measurements for the arms of the folding stock Accurate measurements for the folding stock rear hinge (diameter etc) Accurate measurements for the butt Any accurate dimensions or functional aspects of the spring mechanism that operates the folding stock at the front. Correct dimensions and spacing of the cut grooves that lock the end cap to the lug If you can provide this info you will ensure the accuracy of the dimensions of these templates. This is exactly what this thread is for so post away and I promise I will do your hard work justice for the benefit of the entire community. For years now we have been hearing about how the BBC plans are inaccurate without an adequate replacement. Most legion deployed troopers are still using the BBC plans where real Sterling conversions are unavailable so this project is for any and all of them that we can help build more accurate blasters. We can do it and we can do it soon. The benefits could be huge, and the benefits for those about to embark on a build even bigger. I know form my own experience that one can be about to embrak on build with the plans available, and someone says 'that's inaccurate' and all building plans halt for fear of inaccuracies, but can't be resumed while no more accurate details are available. We can be the people to change that. Let's do it and do it now. Everyone that has them throw the facts and the true dimensions at this post and we will be off and running in no time

My intention with regard to the bolt is to only provide templates for a solid bolt. Mine for example will be made of resin, so there is no way the inner aspects of the gun could work. With regard to the spring loaded folding stock, with all the info we could template it up, the actual accurate building of it with all the intricate parts would be up to the skill of the builder. My thoughts are we could do two - one as is genuine and one that simply functions with the use of a magnet and just looks accurate, for those with less confidence with fiddly building.

Nothing to be ashamed of Steve! I blubbered like a baby when I watched Heart Of An Empire...

Vern, you need to go back in the thread and read the posts more carefully. There are tube templates for BOTH 38mm and 40mm. I've explained the method by which I adjusted the spatial relationships to create the 40mm tube template. We started with the 38mm but the 40mm was created by popular request. If you download the template you will also see that it it explains that the end cap lug is 42mm OD and that you should build accordingly if using a hollow end cap. If you read my post associated with the grip templates you will see that I have covered the issues with legalities and that this grip plan will not make a functioning trigger assembly. I will also cover this again when I create the inside templates, which will not function. With regards to the folding stock, we've also discussed the spring. Now I am still working on it and I can't garauntee yet that the folding stock templates will definitely be spring loaded, but they will be functional. You can see where I've posted the first draft of the folding stock template I've asked for imput and created editable PDF's for those who can contribute. I have been using those great stock photos from your older post as reference and they have been very helpful. It would be awesome for the creation of the folding stock if you could do like Mark and Christian did and mark up any photos with measurements. Any diagrams or info you can provide with respect to the inner workings of the stock would also be appreciated. You're not wrong about how challenging the stock is to template up, and it may well be the case that it ends up replicating the outside only, but this is a replica sterling template not an actual sterling template. That being said I would love to make the stock function so I invite you to jump on board the project and make it the best that it can be!

@ Lichtbringer - thanks so much for taking the time to do that! That's very generous and extremely helpful. @Seantrooper - I'll keep you posted and you keep me posted! @davej - Tell me about it! I've been hunting this down for a few weeks now in an attempt to locate 38.1 outside diameter pipe and wow the measurement system is crazy. The best thing I've been able to do so far is carry my 38.1mm resin muzzle casting around with me and just physically try fitting it to whatever pipe is stock. So far no match though...

Do they have Bunnings in Queensland? I was there yesterday and they carried 40mm PVC as stock. That being said I'm on the hunt for 38.1mm so I'm going pipe shopping and phoning around a bit at the moment. If you can't find 40mm outside diameter near you I could pick you some up if I find and send it over. Better still if I have any success with the 38.1mm I could get that to you

Yes indeed - outside diameter of 40mm. For us Australians it's a standard pipe size, the 38.1mm is Imperial 1.5" and is pretty hard to come by here (at least in my experience).

OK guys, after much help and hard work from Mark at CFO here is the final tube template for an accurate 38.1mm Sterling tube. Every detail has been checked and it also includes the optional end cap lug spacing for those with hollow end caps. This will give you a genuinely accurate Sterling receiver for your E-11 kit. It comes in 3 different PDF's. One is a full size template for those with access to larger format printers and one is a two page PDF which splits the template in two (includes alignment marks) on to internationally standard A4 paper size for easy printing. The final PDF is the same two page set up but on Letter sized paper for our American brethren. Not only that, but after a lot of math (not my favorite activity ) I have an accurate template scaled up for the common 40mm pipe. It is important to note that this template has NOT been scaled up across the board, or by percentages. The tube circumference has been enlarged and the details carefully moved in tiny measurements to maintain accurate relationships but all dimensions and certainly the length wise distances remain accurate. Admittedly I'm talking about centimeters and millimeters here, but there are substantial differences between this template and any other template for a 40mm tube I have been able to find. Taken from sskunky's genuine Sterling receiver these are the most accurate templates I have been able to create for a 40mm tube. These templates are also attached here in the same three formats (large, A4 and letter) as the 38.1mm templates. There is only one important caveat: for a number of reasons there are questions raised by variations on the placement of the rear folding stock mount. You should use discretion when getting the best placement for your folding stock depending on the origin of your stock. Consider this placement accurate for a scratch made folding stock according to the stock templates we are currently perfecting. And of course, as always, all PDF's remain illustrator editable to allow for community improvement if needed.

I hear what you're saying Tray. What we might be able to do is set the max for IPM's higher, so you can do this. I'll check into it for you.

but it's milled - not "bent" as such?

So here's a question for the team: Most templates have the rear sight as one piece and instruct you to bend it. However I have been doing some revision of the measurements for the rear sight, and for a variety of reasons mainly to do with the 2.5mm width of the substrate I don't believe this is actually possible to do and maintain accurate dimensions. The outer curve of the bend is simply too extreme. Witha gap width of 11mm at the base and a height of 15mm on the inside the rear sight has a total inner measurement of 41mm. However with a base width of 16mm and a an outside height of about 18mm the total outer measurement comes in at 52mm. This means 5mm in each curve which is a: very rounded and b: impossible to flat template out without ending up with an inner height that is too tall unless you cut a v groove into the substrate. Bearing in mind I can only examine photographs, it appears from my extensive research that the real Sterling rear sight was in fact two half circles not one bent shape. Can anyone confirm this? It's either that or a template with a large v groove which would not be easy for most folks to cut...

I'm pretty sure I know what it is - I'll get on it.

That's great Christian, thanks. Can you also double check the measurements on the template I uploaded for me? Particularly the parts around the 9 holes in the stock front - that was where I had to do most of my guess work. Meanwhile I'll apply those measurements. Congratulations on your upcoming wedding by the way! As someone who has done it himself I can highly recommend it No worries Mark - looks like Christians got the folding stock covered but I've still a few question marks on the tube template before it gets locked down. Will PM you the relevant bits. Thanks again both of you! This is really coming out great.

Don't stress Eric - its important that you keep us informed. Did this start yesterday or earlier?

Today's Update: The grip assembly - extra special thanks to MArk and Christian for this one. I've had to make some very small steps away from uber accuracy for this one. NONE OF THESE STEPS RELATE TO MEASUREMENTS OR SCALE. The things I've had to alter or improvise all have to do with the inner workings of the trigger/ grip assembly. I've created two kinds of inner grip. One that is solid and non functional, set to fit the non functional trigger template made earlier. The other is a hollow assembly, created for use with the accurate Sterling trigger template, however it does not include any parts related to a working trigger mechanism or genuine Sterling gears and mechanisms. The structure will allow for springs, electronics etc if the builder so desires, but no assembly instructions or measurements have been provided. I did this because firearms laws vary widely from locale to locale and there are many places in the world where making this part function is the first step to a firearms possession charge. The parts will look 100% accurate from the outside, even as a static prop, but anything more "accurate" will have to be the responsibility of the builder. We've all seen the Sterling Owners Manual PDF and you can refer to that if you want to risk building a working trigger. Anyway - legal disclaimers aside - here are the blueprints and templates: I've yet to add the plastic grip, because I'm having a hard time getting a handle (no pun intended) on how exactly to make a template for it being that it's so rounded and really needs sculpting. I will do something as close to accurate as I can but I'd probably recommend buying the outer grip and using it with these custom made parts. they are easily available and shouldn't cause import problems if purchased on their own. This site has them for sale for example: ------------ Boy - we're really getting there now!

Sorry - one more thing... Is the stock catch that attaches to the tube spring loaded or just a slide?

Oh yeah - just to confirm the little tube that mounts the folding stock BEHIND the trigger is 15mm OD yeah?
