Waffenmeister actuator test

[deerslayer]

 

I had two of the waffenmeister actuators come into my hands.  I modified one to 1921 status.   The steel is very hard.  Like their gripmounts.  It appears to be cast steel.  Took twice as long to make as a standard gi actuator.

Good to know Dan thanks for posting. I've eyed those from time to time as I'm on your wait list to have two 28's cut down to 21's. Sounds like it's an easier task for you if surplus GI 28's are used, and less prone to breakage with those I'd guess since they are not cast.

I shot 150 rounds today.  Not exhaustive but it ran flawlessly.   They look very well made.

Nice work Dan!

If the Waffenmeister 1928 actuator is cast steel, can it be as durable as a milled USGI 1928 actuator? I know the cast West Hurley 1928 actuators are junk. That said, can a cast part manufactured today be just as good as a milled part manufactured during World War II.

I am also curious if the Waffenmeister 1928 actuator is manufactured to USGI specifications.

TD,

That would be a good question to ask someone at Ruger firearms.

They make all kinds of high pressure rifle and revolver receivers out of castings.

Ruger uses investment casting. That's a whole 'nother animal.  The end result is the same as if it were machined from billet only a lot less expensive.

I sent Waffenmeisters an email asking about the manufacturing process and material.  Let's see what they say

Thanks for sharing.  This thread reminds me that I still need to source a spare 1928 actuator to have milled to '21 specs to use with my 1928AC

Waffnmeisters confirmed that they are cast, said they will get back to me on the steel spec.

[Bridgeport28A1]

So are Waffenmeisters Thompson Grip Bars also cast steel?

[deerslayer]

I would guess they are cast too.   The gripmounts are almost impossible to drill through.  (Like for quick change barrel option set screw).  They are good quality.  

 

I like the actuators.  They are well made and if, like a quality ruger part are made in a similar way, they should be good to use.

Just heard from Waffenmeisrers.  the actuator is made from 4140,
