Our own Tact2jager currently finalizing his G43 replica kit is well into the build of his even more ambitious FJ42. 3D printing, devotion and creativity at its finest. He has FB pages walking through the entire development process for both. Search FB for each and ask to join.
Once done these will be fabulous additions to our axis offerings and fill some critical voids. As a FB follower Steve seems feedback and suggestions so you have a chance to contribute to each project. For example he showed both a ribbed and unrigged forestock on the FJ and surveyed preferences.

Thanks 2nd Bat /salute! My FG42 project was put on hold to finish up the G43 project, but now I'm back at it. The good thing is that the model was already a year into production so know I'm going back in and adding more detail to the build. Not only details, but re-engineering the model to work for airsoft. I'm trying to keep it simple this time, because I learned a lot from my G43 build, overthinking every assembly just slows things down. I'm also hoping to get more advice from the community regarding gearbox/hopup configurations, currently I'm working on the Outer barrel, inner barrel insert, inner barrel, hopup placement. I plan to line everything up first before moving to other parts. That being said, I ordered a 3/4 inch PVC pipe to be used as the Outer barrel but 3/4 is more like 1.08 inches OD. So this will not work. I'm currently looking for new ideas for the outer, Id prefer to use plastic for the first prototype, but I'm not against the idea of copper/aluminium/steel/ ect.. Once I get the alignment done, and the magazine lined up, I can proceed to finish off the project. I just finished redesigning the bayonet. Total of 4 parts, a split design with working buttons to allow removal of the bayonet (Still WIP). If you would like to follow my build you may ask to join here: www.facebook.com/groups/426876244104566/

About GB - depending on the angle and the handgrip you can consider an all available version 3. If the handgrip is not allowing - you can consider the GB from SVD - A&K that has the motor cage in line with gears. Alternatively - the GB from Sten gun might fit as well.
Technically I would recomend to use an already available base gun as support. For example the Sten gun will have the side magazine already

tact2jager so does this mean that the G43 is done? When will the kits be ready to purchase? Thanks!

Back to GB I think the most promissing is what you have available - V7.
If this is completely unacceptable for your project - let us know what bothers you and we can take it from there. I saw evike has some special GB from S&T for T21 (tavor) and for PPSH. I opened both GB and I can say that the shell looks bullet proof while the internals are crap but it is something you would change any way. If I recall exactly both will take V2 internals. Tavor has a trigger mechanism that might be easier to adapt to FG42. But I would rather go to an electronic controled Mosfet with a trigger switch located in the grip anyway.

tact2jager so does this mean that the G43 is done? When will the kits be ready to purchase? Thanks! Done, but not final. We plan to build the first Beta version this year, meaning, as we build it, I will tweak the designs to make it perfect (Well Im pushing it out in the good enough for now condition, as the community cannot seem to wait any longer). And by tweak I mean, prepare the files and assemblies to be printed with the most efficiency. This will also indicate how long the kit takes to build and how much the kit will cost. A good example of this is the bolt assembly, you will notice that I created the part in sections, (if not, that is how I build it for testing), anyway, if I can print the entire assembly in one shot (without the visible seams), then I'd prefer to do it this way but it still needs to be tested. Perhaps I made the mistake of sharing my kit a little too early, but I assure you, once perfected, it will be available. This also includes the time it will take to create the instructions for the build, and we are hoping to make a few videos explaining the process. For what I have right now is a field tested prototype that needs to be finalised. So to answer the question, mid, to late 2017.

I will be using the V7 (Sten) GB and hopup. I do plan to upgrade the internals to SHS parts (See my page for the alignment). The side feeding hopup was the only one I could find. I have to reposition the trigger assembly as seen in my designs. I already printed and installed the sten trigger assembly but its total crap. So Im going to use a different trigger contact (with mosfet). I can take a look at these other GB's but keep in mind that the size of the receiver is very narrow. *Other custom FG42 builds also use the V7.

If it fits the Sten gun - this is not very expensive and already available. FB is a problem for me - I prefer good old forum ways. The only issue would be that this is only auto. So you might need to use an electronic control device - the cheaper I know is the Jefftron unit

Are you going to keep the base gun or you will print the whole thing?

Are you going to keep the base gun or you will print the whole thing? I plan to print all of the parts needed. I also have plans in the future to have real wood parts, depending if my woodworking guy can match my tolerances, and or cast important parts in metal (Like the bipod legs and bipod base).

You are the expert on the printed parts resistance. As an outer barrel I am using black 16mm metal pipe used to hang curtains at windows. The big issue is the metal is very thin and doesn't support threading. Other options are 15mm copper or 16mm aluminum pipe used for stairs rails. The only issue with the aluminium is comming in bright colors and it is a pain to paint. But it is thicker (1.5-2mm) so you can thread it.

Some great decent progress announced in Tact2jagers FB project page. Feed and magazine challenges, bayonet and other intricate details tackled, barrel and other particulars remain but this is really looking promising.

I have the same issue with a steel pipe I had laying around (Curtain rod around 19mm in Diameter) but very thin. To solve this problem, I plan to 3d print an insert that sits inside the outer barrel (in between the inner barrel and the outer barrel), then line up the holes and apply short screws through the outer barrel and into the insert. The thicker the outer barrel the better, I'm still searching for the perfect outer barrel. Still aligning the hopup/innerbarrel/magazine: *Disregard second hopup hole in the magazine

If you need to move the hop-up forward to fit the mag whole you can consider a longer nozzle for the GB and a "spacer" to keep this alligned with the hop-up. This should help to keep using standard M14 mags. Nozle are available in a wide variation of leght from under 20mm to over 40. I think the longest I found is for TM M4 new generation. You just need to measure the actual dimension of nozle and add the difference needed to allign with the mag feeding whole and choose the most appropriate nozle
About outer barrel - if you are printing a tub to fit tight into the outer barrel as a spacer - you should be good without any screw. If you don't need these screws for design, it will just be very difficult to mask them.

So, if you are going to use wood - it means you are going to late version of the rifle. That's good to know. Do you know if the angle of the grip will fit a version 2 or 3 gearbox?

Thanks for sharing! I think the deal breaker would be mag/hop-up feed. Using a V2 will probably push this too far in the front.

Exactly. While they are the better gearbox, they simply will not fit. Most other custom FG42 builds (both types 1&2) used a V7.

Started printing out the receiver over the weekend, I need to test the fit for the magazine/hopup/ and later on the gearbox. I have to figure out a ways to secure the hopup in place. It has been suggested to replace the spring with O-rings but I will have to find a way to secure the hop up in place. More pictures here: www.facebook.com/groups/426876244104566/

If you are not following the progress on this FJ 42 and G 43 projects along with other WW2 potential products on Steve's Facebook page you should be. He just finalized the FJ 3D printed front handguard assembly which looks fabulous and work on a functional pea grenade type deal modeling the German lemon grenade.

Lots of recent progress on this FJ42 build which appears to be close to finalization. If you haven't already done so go back in the thread, follow the link provided and join tacj's FB link and join his following. His 3D work is superb.

Now over 2 years into this Steve is still tweaking and experimenting. His efforts continue to amaze me but alas I fear he deep down hates the idea of finishing. Again to follow his efforts go to his facebook pages for both the G43 and FJ42. Incredible effort on both of them.

He has it to the point of field testing and as near as I can tell is at a point where it could be printed and sold. I think comercialization is low on Steves interest scale but thats a pitty as it looks and apparently works well and would fill a void in the hobbies needs. www.facebook.com/groups/426876244104566/permalink/2228139687311537/

Tac2jagers finished FJ 42 was nominated as one of the top 10 custom airport guns of the year and finished 4th. Very impressive. There were some other fabulous contenders including a Bren an SMS and an over the top 1800's vintage Gatling gun. Congrats Steve!
