Re: m2 hyde inland from scratch in semi

[snidervolley]

I am taking on a most ambitious task .
in ww2 the us decided to replace the Thompson smg with something better and cheaper ,there first choice was the m2 Hyde inland as produced by marlin firearms co.
it was sent to Aberdeen in 1942 and proved itself better in every category and accepted with an order for 164,000 .
after first 400 where built it was canceled for the far inferior gun the pos m3 grease gun .
I will replicate this gun as close as possible in semiauto and maybe a post dealer sample or two in full.

I will reverse engineer every part as there are only two survivers I know of and I have no access to either and no dimensioned prints exist.
so I will draw blue prints for each part .

My first guess is that the grease gun was cheaper. Cool project though.

blue print for front trunnion and the plastic fit up parts ( I will be printing some of the parts in plastic first and if feasible in stainless steel later

Very cool! Keep us updated on this project.

bolt as made with Thompson for end with laser printed stainless front end trunnion which in actuality replicates the sintered steal on the original very closely

Do you have access t the dimensions?

kwg

OK. I see you do.

 

[Art Eatman]

I'm clueless as to how much hassle, but the US Patent Office has drawings with dimensions. (And all other US-invented guns, as well.)

Are you making a 1 off for yourself or are you going to produce them for resale?

I hate to ask.
But are you fully versed in the ATF laws concerning manufacture of full auto, or 'easily converted' open bolt weapons??

According to Wiki and other sources, the M2 was difficult to manufacture, and required skilled machinist labor. The war effort required a product that was cheap, required no skilled labor, and used the least material.

The M3 Grease gun was designed by the same team of Hyde and an engineer from GM's Inland division to get around the M2's problems.

Here's a quote from Wiki: "The M2 is a simple blowback operated design, although it was difficult to make. The receiver was built from a steel forging and a seamless tubular section, which took extra time and effort to machine and finish, causing the US Army to adopt the M3, instead. The bolt was shaped unusually, having a large diameter at the rear, and being slender in the front. Unlike the M3 it had a fixed wooden stock, and wooden furniture."

Here's another article about them with an exploded drawing: http://www.historicalfirearms.info/...e-inland-m2-submachine-gun-the-hyde-m2-is-the

In this last article, they mention that during testing it was twice as accurate in full auto fire as the Thompson it was to replace. They scored 99 hits out of 100 at 50 yards, full auto, into a 6"x6" square. Obviously, someone who knew how to shoot well.

Not laws. Rulings. They do not have the force of law. Not that it matters. If they can take the gun, remove the trigger and sear , pull back the bolt and let it rip they are going to call it a machine gun whether the rule/law makes any difference.

rc yes i am and these are not easily converted (using as stated a ar15 trigger group and there for closed bolt)and the post dealer samples would be as said and registered as such by a qualified licensed builder

speedo also the gun was an excellent inline design that didnt climb .
