Second, this is only a slight modification of the original Bacon Bow
First the barrel: I used several pieces of 3 different sizes of brass to achieve the nesting/breech setup.
- Piece #1: I cut out the rectangular breech from approx 4" of 1/2" brass. This was permanently gooped to the original (orange) barrel stub.
- Piece #2: I also glued a 17/32" stub directly to the front disk of the plunger tube (after drilling out the centre, of course).
- Piece #3: An even shorter piece of 9/16" brass was nested over ths stub to form a nice solid series of nested brass to support Piece #1.
you can see Piece #2 at the base of the breech in Piece #1 (Piece #3 is in there but not visible):
- A fourth piece was about 9 inches of 9/16 tubing which acted as the barrel. This barrel slides back when the spring/plunger head is pulled back/cocked.
Unlike Piss Bacon's and Lukeinator's version though, I decided to take advantage of the existing (sliding) guide rod located above the plunger (below and forward of the built-in "scope").
I drilled out a hole at the front of the cavity that accommodated the sliding rod and added a length of PETG to extend the guide rod anteriorly (forward). I used some Crazy Glue and hotglue with a piece of the air restrictor from a NiteFinder to connect the PETG to the rod. Sorry, I only took AFTER pics. You can see some of this from above the rod cavity (the front "sight" was hacked off).
here's a view from above the cavity (notice you can see the PETG dimensions on the sticker and part of the NF air restrictor)
This PETG is the "arm" that moves the brass barrel backwards to close the breech. The PETG and barrel were linked using a a copper T coupler, some hose clamps and a piece of picture frame hanging material (metal) bent into a loop (looks a bit like the Omega in the greek alphabet). Oh yeah and some glue and a cable tie to secure the union of the coupler and the bent metal.
Here's the assembled blaster (breech closed):
