M3A1 GREASE GUN AEG VERSION Alright. In my quest to not have to use my M1928 Thompson at events because of the large amount of Thompsons we have in the Midwest I have decided to begin the journey to build an M3A1 Grease Gun to compliment my BAR and Springfield. Our gun god Schmitty has built two of these weapons both of which have come out beautifully. 2nd Bat owns one of them and he loves his Grease Gun. Like Schmitty mine will be made from the Hudson M3A1 GBB Airsoft Gun, I will be exploring the possibility of using the Mp-40 gearbox, hop-up and barrel. I recently purchased a broken Hudson GBB M3A1 Grease Gun from a member here on the boards and I have ordered the internals from an Mp-40 from a person here on the boards and will be using those for the Grease Gun.

If you hold the M3a1 over an AGM MP40. The gearbox, mag, hopup & barrel match almost perfectly.
I thought about converting a springer M3 using MP40, but just don't have any spare time rite now.

Well the Grease Gun came today and Holly Crap its awsome. I ripped into it and tore it donw to its basic components and this thing will be exreamly easy to build. Actually as soon as I get the internals I expest it to take one weekend to build at the most. Considering I have no cosmetic work to o and all I have to do it litterally slip the internals in and glue them in. Teh Im dont. Ill modify whatever magazing I get to work with the mag catch built intot he gun and Im set. This will be sweet.

With the BAR near finished I will soon be starting on the Grease Gun. I have decied that I will buy and AGM Mp-40 and see if the internals will fit. If they do not then I simply will have an Mp-40 to play with also. But if they do I have determined the only cosmetic work on the entire Gun I will have to do will be to make the Mp-40 mags look like M3 Grease Gun mags.

The Thompson magazine housing is completely different with it's unusual channel arrangement which the Grease gun didn't have.
You can buy existing grease gun magazines fairly reasonably (Around 30 dollars from IMA) and then set your donor magazines inside. Real Grease gun mags fit very nicely inside the Hudson body with very little modification. I used Thompson (30 round length) donor magazines which are slightly shorter then the Grease gun magazine but not by much (3/4 of an inch) As such you can use the Huidson/ Grease gun mag release as designed which is also kind of nice.

Well this next weekend I will be seeing if the Mp-40 internals will fit inside the grease gun and if all goes well with that then I will order oen to put inside.
I also have decived I will simply mod the Mp-40 mags to work

The actual Grease gun makes with just a tiny amount of filing fit perfectly in the grease gun and even the release mechanism from the Hudson works perfectly. The magazines are slightly longer then Thompson mags (About an inch) but with Low caps that isn't a concern at all. I really would encourage you to use the actual mag housings. The Thompson innards fit with reasonable modification.

I would love to use actuall grease Gun mags but I simply can not afford too. There roughly $30 for the Grease Gun mag, plus another $20 per 60rnd Thompson mag. Thats after shipping gonna be between $50-$60 per mag. and I want at least 6 of them. So thats a final cost of $360 for them.
Nah Ill be able to make the Mp-40 mags look just like Grease gun mags no problem. Then the cost per mag will only be $20 per mag. Im simply going to put styreen sheet on all sides of the mag to make them smooth like the grease Gun mag and make a small notch at the top of the mag for the mag lever to slip into.

The real M3a1 barrel could be swapped out to fire 9mm. The barrel, bolt, springs, and a magazine adapter for using Sten magazines was part of the conversion. In my book the MP40 mags are politically correct.

Instead of using RS grease gun mags I would recommend using TM MAC-10 mags. They look identical, fit nicely in the Hudson body without sanding the mag well. They will need to be modified for the mag catch and depending on how you arrange the gearbox will determine how the loading port fits. Overall it's the closest cheapest option. They have only just become available or I would have used them in the grease guns I made.

Good to know Schmitty! I had these three spare Grease gun mags sitting around for ever and only recently got around to converting them.

2nd bat: The Mac-10 mags will not fit very tightly in the Grease guns I made because I sanded out the mag wells to accept real M3 Mags. Not that they can't work but they fit pretty sloppy. Had these been available before I would have used them instead of sanding the mag wells.

I just finished doing two additional magazines using the real magazines I had acquired. It really helped having your finished magazine so I knew just where to cut and what the precise fitting would have to be. It was still somewhat awkward and a little challenging. Lots of cutting on the Thompson inner magazines. I assembled them and tested them and they worked great. I put two tiny screws in the top just where you did to hold them in place and have applied some resin paste to fill in the gaps. After they dry overnight and sand and finish and they should be done.
Again so much easier to do with a sample ready mag to go off of. The existing mag release on the Grease gun works great. I didn't realize you had to file the mag well out on the Hudson although as I recall I had to do so on a Hudson back when I had gas gun version. The mag was too tight.
The Grease gun magazine is quite long. Is the Mac 10 mag as long? The greaser mag is a full inch and 1/4 longer then the Thompson 30 round length.

Well Im on the prowle for an Mp-40 now. After Reenactor fest here this upcoming weekend I will be putting what ever money I have left to buying an Mp-40. I have recently Pm'ed a person on the boards here and we shall see if there Mp-40 plus 3 mags are still up for sale. I will hopefully knwo in the next day or two here, and hopefully (depening on hwo much cash I have left over from reenactorfest) I will be able to buy it next week. That will mean I will have all the required parts needed to build the gun over spring break.

Alright becuase I will have several projects going on at once now since my AEG M1918 BAR has been finished I have decided to combine the M3A1 Grease Gun build and the Lee-Enfield SMLE build into one thread as I dont want to annoy people with my many threads all on seperate builds. If people think I should seperate these builds then I will, but I for some reason get the feeling the mods may be annoyed with all of my builds TommyGunner

I think you should seperate them into two different topics you actually follow through with your builds and I think each deserves its own thread. Just my opinion as a mod others may vary.

I agree. I think your threads are helpful and informative as well as inspirational and that you should seperate the two threads. Enroute and once completed they will serve as great resources and there are folks who will be accutely interested in the SMLE who would have no interest in the Grease gun and vic a versa.

Well there was a problem in shipping and the internals have not gotten to me before I had to go back to school. They will probably get here when I am in school so I dont know when I will return home to work on the gun again. But I am working on it lol.

Ok so I had recived all my internals for the gun, I still need a barrel and hop-up unit for it though and cant do much untill I do get those parts.
However I have already started to look at how the gun will go together and the internals will fit beutifully. Beucase of the strange pull rod arrangement for the Mp-40 trigger mechanism I will be able to use the M3 trigger assembly as is and simply attach the rdo to the existing trigger in the M3.
However there is not way in hell I am going to get the internals inside the gun without cutting it in half and then after every thing has been positioned, glue the gun back together. It will work but will require more work than I thought.
At some point I will have pics but that wont be until I come home from school again (who knows when that will be)

Boy howdy does this build need and update!!! Alright here are some pics of an AEG Grease Gun I am actually building for a member here on the boards Jimseery. It has invloved alot, of cutting and thinning of the grease guns body, however it all will fit together and look great when done! The battery will fit above the motor in the empty space and be acessable via removeable end cap at the rear of the reciver. I still have more cutting to do on the end portion of the gun to get the internals to fit. A pic of the hop up and the barrel that I have to cut to length. TommyGunner

Ok, I have all thr parts built and fitted, just have to put it all together now and do the finishing work.
I will say that this project has so far been the hardest I have done, the BAR was easier than this.
I hope to debue it this Saturday at our event!

Wow, It's looking realy good. I wasn't sure what to think when you said you where going to cut the gun in half but now I get it You mentioned glueing it back together? If so how will you access the gearbox later for maintenance or repair? Schmitty

Is there a readily supply of Hudson Grease guns out there? How much did you get your Broken Hudson for? What kind of glue are you using? Just curious.
