m19 build

[bigkilo[TK]]

So - I'm in the process of molding my e11 to offer kits. Bought an m38 scope to mold, but m19s are a bit harder to come by (and certainly more $$), so I thought I would make my own to mold and include as an option in my kits.

 

Its basically a PVC build, I started with a 3/4 in PVC coupler cut down to 1.25" long, and cut 2 very small sections of 3/4" PVC to sandwich the "lens" into place. One of these sections I dremeled the interior to make a thinner ring and added cuts at 3 and 9 o'clock. The "lens" was made from a small segment of a pingpong ball I discovered in my garage. For the objective lens side, I also cut a 3/8 inch long of 1.5" PVC and sanded the exterior to thin it out. This was to become the cap portion of the objective lens.

 

The taper was made with a small section of funnel I had laying around, which I then connected to a 3/4" PVC cap that I had belt sanded to be flat on the top and smooth on the sides.

 

The front end parts:

 

Broken down - the 3/4 inch coupler with a section of 3/4" PVC within:

 

Then the pingpong segment and thinned out 3/4" PVC ring next:

 

And the thinned out 1.25" pvc placed around the exterior of the front ( this had to be cut with some removed so that it sit flush with the 3/4" coupler):

 

Then I glued the objective lens assembly to the funnel and then to the 3/4" PVC cap, which was shortened to ~3/4", then I cutout two slightly smaller circles from some scrap abs sheets to attach to the ocular end:

 

Then I used scrap copper pipe and copper couplers to make the side tube and ocular lens housing (I believed this was 3/8" copper tubing). Then I dremeled out the funnel area to attach the side tube and glued it in place

 

Next was to bondo the whole thing to blend and smooth the body

First pass:

Second pass:

 

Wood and abs cut and stacked and glued to make the two bottom feet

*forgot to take a picture of this*

 

Added three "screws" to the objective lens end (actually, I drilled holes, filled em with bon do, and used a screwdriver to imprint a flathead screwdriver slot into the bon do - looks convincing enough in person

 

And painted it up - ready to mold! I weathered it a bit to have some pitting, scratches, and other imperfections so it matches the rest of my gun. I really want these to come out of the mold "pre-weathered"

 

Its not a 100% match, but it is close enough to convince most, I would say. Some of the incorrectness I kept on purpose as kind of a signature:)

 

Final cost was almost free, since I used mostly scraps, but I imagine it could be done for under $10

I have an m19 mold I can sell you made from latex rubber

Now you tell me:). You are just the man with the solution, aren't you Vince? Well, I am going ahead and finishing this build, but I am certainly open to solicitation regarding an already completed mold. But latex? Does that even work? I'm using smooth on mold star silicone. Have done the whole GE silicone tube thing with mediocre results, and have done a couple urethane castings for cement - never used latex. Wouldn't that get shredded after 1-2 pulls?
