Last Chance for Superbolts Update #3

solved the superbolt problem GET RID OF THE DELRIN SLEEVE.
the reason for the bump at the top of the sleeve is because
the body was turned down to clear the spring Right?
The bump at the end is the actual .68" diameter of the normal bolt
The spring is located concentrically at the washer inside
the body. On the bolt the spring is located by a slightly
larger diameter on the ss part.

when inside the breech and barrel the bolt is located by
the front of the bolt, and guided somewhat by the powertube.

the solution. take a normal bolt turn down the body as you
do for the superbolt but leave the end at the .68' diameter.
drill out the stem as you do for the superbolt
or make the stem out of hard anodized aluminum.(Assuming
you can find the correct brazing metal to join aluminum and
stainless)
The delrin does not remove weight it adds it,AS it is only there
to replicate the original steel bolt profile

So what do you think

So when the next ball rides along the top of the bolt it will fall into that void created by the differing diameters and get chopped by the bolt retuning to cocked position.

Very Bad Results...

Well, last night, I cooked my bolt, and then sanded it done on the ridge as recommended. My sanding job was much ruffer than yours, but I got it back as smooth as possible. Today at lunch, I went to the paintball store and got some nitro for the tank. Tonight, I put in the superbolt and shot 500 shots. I was getting a little bolt stick on my emag at first. It was like I would pull trigger once and bolt would fire and kinda stick, then a second pull would release it and cock it again. It happened around shots 175-225, then stopped. I shot my 500 shots and stopped and checked the bolt. It seemed fine. When I put it back in, I changed barrels. The original was a Smart Parts Progressive, and the second one was a CP One Piece. The new one didn't have the bolt stick problem, so I just kept on firing. Around shot 1450, the gun began making a funny ringing sound when fired. I stopped and took it apart and discovered that the sleeve had come off in entirety and was lodged in the top of my barrel. I was firing with my condom on btw... I had read the posts about the sleeve being loose and needing gluing, but mine was still tight before I started. No chips or breaks or anything, and it looks like the delrin sleeve would slide right back on and glue on. I will call in the am and get an RMA# to send it back to you. Dangit, this bolt feels so good when it is working. I hope we can get these problems figured out.


Update: called Thursday afternoon and talked to Jon. RA#:86236 will be on its way back to AGD Friday!

Butterfingers I honestly didn't think about that,nice catch
aren't public forums great.
However how about the blowback ? It would lift the ball away
from the bolt. just a question of whether the bolt retracts
faster than the ball bounces back.
Of course if the ball does bounce back faster than the bolt
retracts, the ball would run into the bolt,and not into the breach,
that kind of calls into question the whole principle of powerfeed in the first place.
Warpfeed might be a problem though.
Besides the bump has already been introduced, its a
question of how extreme it can be.
Maybe it is a bad idea or maybe the beginning of a good one.

If you are having problems please RA the bolts back to us. We are remachining the sleeves now to reduce the bump.

Thanks for your cooperation,

AGD

Tom,

If it isn't too much trouble, could you post a thread or notice to let us now when the superbolts are available in the online store again? Thanks.

when i recieved my sb and tried to insert it into my main body it was too fat. i had read something about a problem that could be fixed by sanding it down. it was refering to the ones that was too long. so i assumed that the bad sb's were all too fat before checking ao i sanded the tip(outside diameter) with 300 or 400 grit sand paper until it fit snug with no resistance. i shot several dry shots before i ever tried it with paint no problems when i tried it with paint i was chopping with my warp and e mag. i checked ao and relized my velocity needed to be readjusted. i was shooting 353fps after i re adjusted i have not broken a ball in my e mag or classic mag. i have played three weekends in a row with no breaks. approx 2500 balls and atleast that many more dry fires.hope this helps i would be glad to answer any more questions you may have .

[oneshot]

boiled bolt , then sanded it,

550 dry fired shots , and a hopper with paint, no sign of any cracking

hope this helps

[headcase]

I got my SB back from AGD with all the updates(foamy, sanded, I can only assume it was boiled) I dry fired around 2000 times and the bolt looks fine still, also fired some pro-ball that has been open for 2 weeks and had a broken ball or two in the bag, without a single brake or chop.

What has been done to them???

Well, I got home today from work, but after 7:00pm, and found a UPS sticker on my back door. I have a package from Airgun, but unfortunately, since I didn't call them until after 7:00pm, I can't pick up the package until Tuesday. It is my superbolt back from AGD. What has been done to them? Has anyone besides headcase gotten theirs returned? What are the results? I am chomping at the bit here!!! :)

foamie

how do you make a foamie and put it on?

[sifu01]

HEY! Im excited and waiting to get my superbolt. I was just wondering if AGD could throw us a bone here and give us an update!!!! PLEASE!

[TITAN]

Tom- if you eventually cant find a solution to fix the delrin sleeve I would like to suggest using Ertalyte or Nyube which are both frictionless plastic but are supposedly much more stronger and durable than delrin.

Problem?

Recieved new machined, boiled, and foamied bolt for AGD. Did not have a chance to put it through its paces until super bowl sunday. Played a couple of practice sets for the best in the west tourney this weekend. Before I post problem my gun specs: Micro Mag RT vert feed with Halo;Dye Boomy(.687) and Lapco big stot; 3000 flatline set to 750psi output; chrono'd 292,295,293,292; Brand new box of Marbs and RP premium. Bolt has no recoil, but breaks paint! The premium was the worst, I could not pull the trigger without breaking a ball( yes it was new paint not something in the shop for three weeks). Sqeegied clean and repeated process. Pulled valve out to see if paint shell was stuck on spring or in breach, nothing there. Switched to Marbs and it was alot better, but I broke one out of every 100 balls. Didn't matter which barrel was used. Replaced stock bolt and did not have a problem with marb or premium the rest of the day . I really like the superbolt but, it breaks to much paint. NO I'M NOT SHORT STROKING, well I did once but the bolt was so light(more dwell) that allowed it to double feed instead of chop .

Thx, B

[AGD]

Micro,

If you are double feeding at any time you have a problem with your nubbins. Chopping is always a feed issue not a bolt issue. Breaking down the barrel is a bolt or breach issue.

So how has the reaction to the superbolt fix been with people your in contact with play with them TK? Just wondering if breaking is down or what not?
