The basic idea is that I want to use Zorn Lemma's BBB Overhaul idea.
Except that I want to make the bow more like the old Nerf Bow, in removing the handles; and building a handle on the plunger.
Things that I want to do to this BBB (some straight from from Zorn's Thread)
-I'm removing the back half, so I won't need reinforced parts in the back half; I filled mine with green stuff (a games workshop epoxy putty, it's green and blue... I actually don't know if it's safe compared to expoxy putty. D: Does anyone here know any better? The stuff becomes very hard, and is normally used to fill gaps in metal models; or help bond metal models)
-I'm going for the Method 2 Plunger Head; a series of metal and neoprene washers
-I want a more resilient plunger shaft; so I'm thinking of building the above Plunger Head on a length of threaded rod. (good idea? bad idea?)
-Build a handle to draw back the plunger
-Place a washer at the base of the plunger tube to reinforce the plunger tube
Hopefully, I'll be able to get some threaded rod that's a good length.

Is the bulk of the original interals that I'll probably keep. If I have my way; I'll replace the plunger tube with a threaded pipe, and a screw-on cap that is epoxied or glued to keep it in place. I'm not sure this is possible.
Of course, I'm thinking about replacing the spring; but I might keep it b/c of lower draw weight, and saftey concerns; a real "Bow" cannont have greater than a 20 lb pull when using modified normal arrows for what I'll be using it for. So getting a 100' range isn't necessarily good.
Accuracy is really what I want. Not retarded power/range.
I've got a feeling that I might "over" build some parts if I use a metal tube for the plunger tube, but whatever, the "bow" will last that much longer.
.... actually, now that I think about it, some of the black ABS piping could be used to make a plunger assembly, maybe replace the front piece with an ABS to PVC coupling, and see if I can get something that fits the inner diameter of the ammo type that I'm planning on using (Fome's "Arrows" made from grey pipe insulation specifically)
Anyway, the "remaining" parts that I want to have left will be pretty much this:

The plunger rod is just there because I didn't remove it. In hindsight, the reinforcing of the plunger rod is unnessecary, but w/e.
I'm planning on doing mostly cosmetic work after that. Hopefully it turns out well. I find that it's just a matter of planning and patience when it comes to building purely cosmetic things though, so I'm not too worried.
Edit: for some reason, I can't nest URL (link) and IMG (image) BBcode; Url BBcode around Img BBcode gives me text with a link, and Img around Url seems to do the same. Also, resizing images to make them smaller isn't implemented on these boards. D: Ah well, I'll just post the full images.
