My new E-Bolt project:
Update 1 Well, after putting everything together, I tested it with CO2 in a vertical position on a remote coil. Why CO2? I was desperate and out of air. I have encountered some problems. ------------- Evil Elvis: "Detrevni is definally like a hillbilly hippy from hell"

| psychobalistics made a pretty good cocker, the lightning, its pretty fussy and a lot of people say they arnt built well and need a lot fo work, but they are very accurate, ive tested it and it is ever so slightly better than my freeflows accuracy. unfortunatly pretty much everything on the psycho breaks... |

Sounds like it should be a fun project. I'll look forward to updates.

Alright DeTrevni, Here's what you do.
Look at the silver ram housing. Notice how the two rings down by the actual brass ram are further apart than the others? Those two are the ones that fit where the rings on the end-cap sat. Now, take your right hand clam-shell. Place the board in the hollow recess of the handle, get your ASA screws, retaining bolts, and new double-tapped ASA and figure out the bolt depth. Give yourself 1/16 - 1/8th of an inch leeway above the end of the bolts (screwed all the way in with the ASA on) and mark that as the bottom position of the board. This is where you will want the board to sit so you don't accidentally screw the ASA bolts into it and fry the sucker. Now, very carefully, use a very small dremmel grinding bit to grind out a half-circle at the front-lower corner of each side of the receivers' grips to allow passage of the lp line from the micro-rock to the solenoid that will be housed on the board inside the grips. Make sure you remove enough metal to let the LP line sit inside without pinching as that would restrict air-flow. Don't go too-big or you'll let moisture and dirt get in the grip and potentially mess up the board. You'll also need to notch the bottom front of each grip panel to allow the lp line to pass through. On the left clam-shell, mark 1/3" wide by 2" long rectangle which runs lengthwise perpendicular to the length of the grip approximately above where the board's dip-switches are located on the other half of the clam-shell. Using a cutting wheel, remove this section and file it down so that you can access the panel by simply removing one grip-panel rather than dis-assembling the marker. Now, when putting everything back together you won't need the hammer, charging handle, end-cap, drive spring, or hammer buffer-ring, sear, sear springs, etc. You'll just need the trigger and the pin that allows it to pivot as well as the two pins that sit behind it. The two pins behind the trigger allow you to mount the micro-switch in place of the sear and trigger spring. Fix the board to the inside right half of the clam-shell (I used a dollop of hot-glue, but didn't have the video, so you should probably watch it and see what it says) and run the LP line from the lower input on the solenoid out the bottom of the grip frame. Run more lp line from the upper output of the solenoid to the barb on the back of the ram housing. It should have a recessed cut in the bottom of the ram housing to allow the line to pass out the back of the marker body to the barb without pinching or needing to mill the marker body. Once all of this is done, place the left-side of the clam-shell over the right side (with all parts placed inside) making sure the battery connection cable comes up through the charging handle opening on the left receiver half. Once the shell is in place, I suggest attaching a battery to the connection to make things easier. Use the battery-cover to cover the battery and the new bolts (about 6 threads longer than your old ones) to affix the whole thing to the marker sealing off the charging handle opening like a rocket-cock would. If the battery cable has an on/off switch on it, it should go through the rear of the battery housing, not sure if the PB ones did or not though. It's an easy enough mod mind you. Now, put the new ASA on and run your bottom line to one side. (I prefer the left side) use the 90*NPT fitting on the other side and thread the micro-rock into it. Connect the lp-line from the grip to the rock and trim as necessary. Now, with the power to the board on and the LPR turned down to zero, gas up the marker. Slowly turn the lpr up until you hear a hiss come from the solenoid/ram. When this occurs, turn the lpr back until the hissing stops (usually 1/8-1/4 turn) Now, chronograph the marker. If you bring you velocity screw flush to the body, you can use the lpr to change the dwell and chrono the marker that way, just like any other electro-pneumatic marker. If you have any problems, feel free to ask!  ------------- <Removed overly wide sig. Tsk, you know better.> |

Yep! Nabbed it from Raion. Tallen, thanks for the info, but I also got Model 98 receivers for it, so it should just drop in. If not, I'm sure I can make it work! This isn't my first E-Bolt project, but the other one crapped out, due to no fault of mine. It was a BSI kit, and regrettably, the board was fried. I still have the ram, battery housing and solenoid, should anyone want them (for a price.  )OMG NO SELLING NEWB! As for Psychoballistics, they did make good project 'cockers, and had a light body, but were only worth a darn if you replaced the pneumatics, feedneck and frame, which is greater than the cost of the 'cocker itself... Also, you'll have a hard time convincing me one 'cocker is more accurate than another under the same conditions. Or any gun for that matter. EDIT: I edited my first post with a running price list, to keep y'all updated. I also look forward to see where this goes, as to I'm not even sure yet. May try to make my failed E-Bolt project work, but I don't know if I can. Also, I decided to go with the E-Bolt over the Sniper and Pneumag for 5 reasons: playability, awe effect, customization, affordability and I've always wanted one.

Yep. Raion said she had a few. I don't know how many that is, but if you REALLY want one, now would be the time to jump. Keep in mind, these are for the original Model 98, and with some slight modification, the 98 Custom. If you have a new-style 98c or a 98c Pro, it will take a LOT of milling and grinding to make these work. ------------- Evil Elvis: "Detrevni is definally like a hillbilly hippy from hell"

I have an old style 98 custom, I got it 8 or so year ago (before the A-5 came out). Its still stock, I figured it was just a better value to save my $, and get a better marker down the line. However I have picked up some good deals on clearance for it (Dye UL barrel back for $5, at the same time i picked up a bunch of Angel LCD parts and upgrades for an additional $10). I just don't know if I can justify spending $135 dollars,... money I don't really have to spend right now. ------------- 2005 Freestyle Naughty Dawg Freestyle Angel LCD SP-8 Tippmann 98 Custom |

DT, if it's a "Gilled" M98 (one of the original bodies) you soooo have to mill out the gills my man! ------------- <Removed overly wide sig. Tsk, you know better.> |
Posted By: DeTrevni

It is. There's the Model 98, the 98 Custom and the 98c Pro. Each is a different version, so I just call the original 98 the M98. Just for clarification's sake.  The only thing keeping me from doing the gill mill is that when I'm done with the project, I'm probably gonna need some sort of anti-chop device. I'm not sure, but if I cut off the gills entirely around where the eyes will be, would there enough meat on the receiver to use eyes? Know what I mean? I'll draw plans soon. When I get the eyes figured out, I'll cut out the gills around the eyes. It should work, and look awesome! If there isn't enough meat for eyes, I'll just do that home-brew anti-chop bolt system. Edit: I don't know. The gill mill would give a lot of room for dirt to get in and crap everything up... ------------- Evil Elvis: "Detrevni is definally like a hillbilly hippy from hell"

That's psycho man. Are you doing break beam or reflective? Either way I'd place the vision system so it looks at the bottom of the chamber. |

true on the dirt part. as for eyes, there's no place with enough meat on a M98 to put eyes. Just use a good hopper and you won't chop. We're talking 15bps max out of an e-bolt anyway. ------------- <Removed overly wide sig. Tsk, you know better.> |

If I don't find a way to 2-way it, that is! It looks like the ram housing extends all the way to the beginning of the hammer, making 2-waying it difficult. BUT, with a drill press and a dremel, I bet I can make it work! EDIT: If it doesn't, I still have the BSI ram to work with. ------------- Evil Elvis: "Detrevni is definally like a hillbilly hippy from hell"

shouldn't be an issue, but.... you're going to need another board with a 3-way solenoid. (1 in, 2 out) ------------- <Removed overly wide sig. Tsk, you know better.> |

Same here. I always wanted to e-bolt a 98c, some more ups, and do some custom milling. But thats a project for when I have money to throw around. -------------

I'm down. This may take longer than the SL build off-however... I'm willing to bet (figuratively) I can compete with the Predator! Edit: I changed my mind. This marker is gonna be built to MY preferences, and I don't expect it will be too pretty. Of course I'm not gonna let it get ugly, but it definitely won't be a "show marker." ------------- Evil Elvis: "Detrevni is definally like a hillbilly hippy from hell"
