Waterworks Posted December 15, 2019 Share Posted December 15, 2019 I'm fabricating a non functional replica STEN mkII and need just need to know what the thickness of the butt plate and grip piece steel sheet is ? And the spacing and diameter of the holes in the barrel sleeve. Thanks. Quote Link to comment Share on other sites More sharing options...

Chris Hall Posted December 18, 2019 Share Posted December 18, 2019 Yes, those plans aren’t accurate, there’s some dimensions that if you follow, they won’t fit. Also, they are different to the original so aren’t interchangeable. Quote Link to comment Share on other sites More sharing options...
Waterworks Posted December 18, 2019 Author Share Posted December 18, 2019 Perhaps @eddy8men if he has the time could check the dimensions of his STEN to the plans and see what the score is ? Quote Link to comment Share on other sites More sharing options...
Chris Hall Posted December 18, 2019 Share Posted December 18, 2019 The whole front barrel trunnion is different, you can’t even compare dimensions as they are so different. The face of the trunnion should nearly in line with the magazine opening, the one in the plans is something like 4mm out. Also the ejection port is almost parallel with the mag opening, a real STENs ejection port is something like 20mm further back. Quote Link to comment Share on other sites More sharing options...
BC312 Posted December 18, 2019 Share Posted December 18, 2019 The original sizes will be in inches imperial so what looks 6mm or near would most probably be 1/4 inch 6.35mm etc etc Quote Link to comment Share on other sites More sharing options...

Chris Hall Posted December 18, 2019 Share Posted December 18, 2019 The threads are out to, the TMH cover is held with 2 x 2BA round head screws the same as the mag release catch retainer screw. The barrel nut, if I remember correctly is 22TPI UNS. Quote Link to comment Share on other sites More sharing options...
Waterworks Posted January 7, 2020 Author Share Posted January 7, 2020 I'm only really interested in the external dimensions as my replica will have the barrel and barrel sleeve fixed in place, no trigger mechanism, and no way to feed cartridges from the magazine.

Waterworks Posted April 5, 2020 Author Share Posted April 5, 2020 The lockdown has put me back on this project, I've got some measurements off a mk5 but I'm still looking for Mk II stock dimensions. And a cheap magazine. Quote Link to comment Share on other sites More sharing options...
BC312 Posted April 5, 2020 Share Posted April 5, 2020 Sten mags at the big shows were £3 a pop not that long ago brand new in grease. Cant get them cheaper than that. which stock do you want as there are two types, T stock or the gun shape open frame job. You can buy them on ebay as i have seen these up for grabs on there from time to time. Quote Link to comment Share on other sites More sharing options...
ferretfixer Posted April 5, 2020 Share Posted April 5, 2020 Also in these Plans. The barrel Latch, or in Reality. The Mag Housing Positioning Plunger. Is nothing like an original..... & missing the barrel nut retainer plate. Which would prevent the barrel nut from unscrewing when being fired on a Live fire Sten.

I don't want to buy any parts except a mag , mainspring and its end cap which are not practical or economical to fabricate. Quote Link to comment Share on other sites More sharing options...

Those plans are certainly different to what I'm finding by measuring STENS. The rumour is that they are from a metric Israeli STEN copy.

Chris Hall Posted April 5, 2020 Share Posted April 5, 2020 It’s not an Israeli copy, those are near identical to the Standard STEN to the point it’s hard to differentiate at times. I think the plans are just easy DIY plans removing some of the more difficult engineering aspects. Quote Link to comment Share on other sites More sharing options...
Waterworks Posted April 5, 2020 Author Share Posted April 5, 2020 OK, I'm finding 2 mm or more difference in some parts like the main tube end bushing, and the barrel sleeve is 60 mm longer than a MK II. I don't trust those plans at all. Quote Link to comment Share on other sites More sharing options...
Chris Hall Posted April 5, 2020 Share Posted April 5, 2020 No I wouldn’t, it would be easy to custom fit everything but it could end up looking nothing like a correct mk2 Quote Link to comment Share on other sites More sharing options...
BC312 Posted April 5, 2020 Share Posted April 5, 2020 As for going to a show, you get a friend to get you one. Obviously no show on this year, your have to wait till next year. Quote Link to comment Share on other sites More sharing options...
Chris Hall Posted April 5, 2020 Share Posted April 5, 2020 Have you seen this chap on Gun-star? He’s well known and legit. https://www.gunstar.co.uk/parts-kit-complete-royal-ordnance-factories-sten-submachine-/Deactivated-Guns/1186888 Perhaps you could buy some of the harder parts to make? He sells a kit or individual parts so can be your choice. I’ve bought a spring kit and a few other bits from him and he’s very quick to respond to messages.

Waterworks Posted April 5, 2020 Author Share Posted April 5, 2020 I will see how it turns out first before I buy any parts, the magazine, the main spring and its cup are the only parts worth buying for me personally as I worked in metal work, welding and fabrication .

ferretfixer Posted April 17, 2020 Share Posted April 17, 2020 It just occurred to Me. Your Name on here is 'Waterworks'. & one of the many Names given to the sten. Was 'The Plummer's Delight'! Lol Quote Link to comment Share on other sites More sharing options...
