STORY TIME!

I bought a rough cut a few months ago (the white one, if that makes a difference) and decided to give it a paintjob. It worked fine out of the box. When I opened the blaster for the first time I was happy to see that all the internals were "connected" in one big chunk that I could just lift out of the blaster without any trouble. I took the guts out, painted the blaster, put the parts back in and fired a few darts. So far so good. However, when I tried to use slam-fire, the priming handle locked up. I was able to pull it back and then forward (almost) all the way with the trigger pressed, but no dart fired. When I tried to pull it back, I stripped some gear teeth making ANY priming impossible.

After a few weeks of mourning my useless but really cool-looking (which made it even more sad) blaster, I decided to just go buy a new rough cut and do a full internals transplant. Again, super easy because it's like replacing one big piece. I tested rough cut B out of the box and slam-fire was working perfectly. After dropping the new parts into rough cut A, slamfire would not work and despite countless surgeries over the last two months I cannot find any missing/broken parts in this thing.

So now I'm asking here: Is there some magical piece in the rough cut that makes or breaks slam-fire that I should check specifically? What could I be missing?

Thanks for your time!

Gut the electronics, drill a hole in the shell, and attach a crank to the gear. Bam, crank-action stampede that doesn't require batteries, or even a trigger.

...(also judging by your past posts, I would consider you pretty dang wise elder like in the modding community :lol: )

Photos. Photos photos photos. This might help us diagnose your problem, especially those more familiar with roughcuts. Additionally, check out the internals pictures thread and see if you are misassembling the blaster in some way.

Thanks Aeromech! I'll get pictures up tomorrow.

EDIT: I just checked the internals directory and didn't see the rough cut listed :( I've actually started messing with the gears to see if there's some sort of default position they need to start in to see if that makes a difference. So far no luck.

There is most definitely a specific position that the gears and racks need to be in. I've found that the rack connected to the pump grip in particular can slip out of place even if you leave the internals "chunk" together.

Thanks. Yeah I was just messing with that and I'm starting to fear that it might be the other rack under the plunger tubes that's out of alignment.

Try taking the pump rack out and put the plunger rack all the way forward. Then put the pump rack in almost all the way forward...I think it should have 2 to 3 teeth behind the gear that it meshes with.

Basically, the plunger rack needs to be all the way forward by the time the pump reaches the front of the slots. The plunger pusher/rack is what moves the slamfire hammer into place, where it can engage the trigger's ramp.

Yeah, I figured that out. That's actually not the problem, THIS is:

There is a tiny amount of wear on the chunk of plastic on the plunger rack that pulls the long piece "B" (I colored it green) forward. Normally, if your pushing the priming handle forward with the trigger pulled, piece "B" engages the catch and voila! You have slam-fire. What happens here is that there's too much wiggle room and that nub on piece "A" is able to slip over without pulling "B" forward.

First picture looks to me like the top rack can move further forward, but I'll have to open mine up later today to check out what's supposed to hit where.

It can and does, I pulled them apart a little so the two pieces would be clearly separate from each other. In picture two there together as far as they go.

I also had this problem with my white out roughcut.I am very interested to see what the problem is.

I doubt that you have 1/8" of "wear" on that piece. It looks like it was just set back one or two teeth on the rack (linear gear). I'm NOT a roughcut expert, but it seems like you might be able to fix the problem by adjusting the interface between the rack and gear.

Inspect the blaster carefully, like I said I have rarely seen this blaster but it seems more likely that the rack simply slipped out of it's proper timing with the gears.

The two surfaces on A and B on my rough cut are totally square http://i162.photobuc...210_000015.jpg.

Whereas your second picture seems to be pointing out some round-ness, right?

And yeah, with the gears taken out and my punter rack all the way forward in its track, the slamfire hammer cannot move backwards at all.

Edit: This is my bone stock white rough cut. Note that the back of the bottom rack is pretty much even with the gear housing contrary to how I finagle d my blue one. I just opened this thing for the first time and that's how it was. Slamfire works beautifully on this one, easily allowing me to single shot slamfire (hope it's still like that when I put it back together!)
