The idea here is to take a pair of AGM mkII Sten's and using as many genuine or reproductio parts as possible to convert them to mkV's ,the project is aimed at the highest standard possible but at the same time showing how it could be done more simply as a DIY .
This project has been on the books since before completion of the Owen gun but has been stalled several times waiting for components so to me its felt like it started long ago but in fact I only started cutting metal today .
One of the important design ideals I've been tasked to achieve is to have the stock to be fitted in the proper easy clip on way of the original using a sprung button design ,I'm working with a pair of genuine stocks and genuine spring caps that incorporate the take down button .the spring caps fit inside the receiver tube perfectly however part of the space contains the gearbox motor so a section needs to be cut away ,the next thing is the hole on the rear sight barrel band assembly ,this is a small threaded hole in the AGM but I need it to be 15.6mm for the button on the spring cap to go through so it was bored out on the lath ,the lath means I can do this accurately but a hand drill and files would also work .
In the real gun the spring cap would be under compression from the main spring ,while the air soft gearbox occupies much of the space where the main spring would go however I plan to use a narrower spring that goes over the top of the motor and butt up against the back of the gearbox to act on the spring cap ,this will not unfortunately go all the way forward to the fake bolt so I plan on adding some sections of spring on to the rear of the fake bolt to make it look like a complete spring ,these fake spring sections will be further out than the real spring so when the bolt is pulled back to open the ejection port they will move past and over the real spring ,its not perfect but will look heaps better than standard AGM.

a problem shared is a problem halved ,but an advantage shared is no advantage at all
if a job's not worth doing then its certainly not worth doing well
i also separated the first trigger housing , the front half will be modified and re used but the rear section will be made from scratch .

Looks good so far Gav, be interesting to see this one take shape!
I'm hopeing it will be quite straight forward ,the stock mounting and trigger housing are the complicated bits .

revised stock mounting system , new design uses the original end cap that has the half twist bayonet fitting , the horizontal bar on the original mounting is now completely removed ,its replaced by a sleeve that fits into the rear main tube and has the "L" shaped cut outs for the twist lock cap that retains the spring and stock locking cap,this sleeve will be welded onto the main tube , this means the rear sight barrel band part won't be under spring tension and as its only held on by one 3 mm screw its for the best .

Gav.. That looks just like the real ones. Fantastic work.

Ordered springs today ,finally found some that were not chromed .I also separated the second trigger housing so while I wait on spring and tubing I'll modify the front part of the trigger housing's as they are a bit shorter at the front ,the rear section will be fabricated .the tubing on order is for the front barrel shroud ,its 1.5inch and much narrower than the mkII barrel shroud and as it also is the mounting for the reproduction fore grips it has to be changed for more than just aesthetic reasons ,while there I want to find a better way to mount the barrel shroud than one countersunk Phillips screw

Yes, buttstocks are the easiest part* of a STEN to find!

Spring and barrel shroud tubing arrived so i temporarily fitted the rear baronet fitting for the stock catch and put it together , there's a really nice feel to the locking button , i need to weld on a return lip on the back of the barrel band/sight assembly as the AGM has none .
Also cut and terned down the front barrel shroud tubing and the alloy hop mounting piece to fit , now i just need to work out how many rows of holes to drill in the shrouds ,it seems to vary depending on what picture you look at , some had three rows ,some four and some seem to have 5 rows so i'll have to peer at a lot of photo's of mkv's and pick the most common number unless Chris had a number in mind ?

Looking great. I wish I had your mechanical skills.

After a lot of looking at mkv pictures I'm leaning toward 5 rows of holes in the barrel shroud ,5 seems most common followed by 3 ,I can't find any with the 4 rows as AGM went for ,I guess it was easiest to machine ,just 6 holes, in one side out the other and job done ,pity its wrong but that never stopped the Chinese air soft gun makers.

After some deliberation and discussion I went for 6 holes to the front and 3 at the rear ,such a small detail but it makes the difference ,sometimes a compromise has to be found in one area of a project but if you get the other details right then it goes unnoticed ,so far no compromises though

holes drilled ,sounds a small thing but marking them out before drilling takes a little time and precision ,you also have to drill them to 7.5mm then use a mill cutter of 8mm one each hole otherwise when drilling into tube the drill bit tends to give a semi triangular off round hole and the mill cutters don't suffer this effect but you cant really drill with them either so its a longer process than it sounds.

Nothing much to see but I was waiting on some of the parts for one of the guns as they were posted in two parcels so today was catch up on the modifications to those parts in the second parcel ,other than that I welded in the sleeves for the spring caps at the rear .
I'm afraid that's all for this weekend as I'm in shift lag going from nights to days so i didn't get up very early and i'm working on Sunday to boot 
,I have some shorter shifts coming so I might squeeze a few hours in during the afternoon's next week .

Some mini and micro deans connectors arrived today to play with , I have a plan in mind where as the stock is pushed up and locked in place it will also mate a pair of connectors meaning there won't be an unsightly umbilical cord of plugs and wires between the gun and stock ,to this end I ordered the deans plugs to see if they would fit ,after a little more research I found the micro deans are only good for 5-10amps so not enough really but the mini deans are good for 15amps and as these are not hyped up BB hoses that should be fine ,strangely the mini deans are a little shorter than the micro's as well .anyway after offering them up it looks very promising ,I'm not 100% sure its possible yet until I have the new lower receivers (trigger housings ) finished I won't know for sure but I'm going to pursue it as the main plan ,of course its not essential to the build and if your looking at trying this out as a conversion then plugs and wires will work very well.

A section of 35 mm steel round bar arrived as well last week so the barrel shrouds now have their internal mountings made , they screw into the the front of the receiver as the original barrel did with a 17 mm fine pitch thread and new barrels once made will screw into the shroud with a 14 mm left hand thread .The inside threaded section is at present an interference fit or in layman's terms its pressed in with a hydraulic press ,i may decide later on to weld them as well if they show any sign of moving .

New barrels made , i might take the narrow section back a bit , they are meant to have a step down in diameter just outside the shroud , i think I've made it too far outside the shroud by maybe 3 or 4 mm ,anyway you get the picture.
