I've been hearing bits and pieces about people combining lurker bolt parts on their boss bolts. Can someone explain to me in further detail how to do this? Pictures? Settings? Love?

It's actually the other way around. You add Boss's orings and delrin spacer onto the Lurker Eigenbolt. It adds a soft cushion for the bolt during it's forward movement, as well as aligns the Eigenbolt's rear bolt sail with the bolt guide dump holes a lot better, allowing the poppet sweet spot to be further in, causing efficiency gains. Combine that with the Eiegnbolt's rear spacer design, your bolt is now padded on both sides.

Here's what my bolt engine looks like:

Stock spring or one of the Boss?

[incognito-z]

That looks like the stock spring, from what I can see.

[Teahouser]

Stock spring. Works the best with this set up. 160psi.

[Blak Katalyst]

I wanna try this, thanks Teahouser

[WhiteStripes]

Some marker mad science up in here!!! killer idea Teahouser!

[Razyger]

Nice, I like it. Would be very curious to shoot it and see how smooth the blurker'ed Mini is. Did you have to adjust your OP with and without the Boss cushion ring? Did you have to re-tune it, or did the optimal settings stay the same? I guess you mentioned that the back cap is turned in a bit more.

i've been running a 'Blurker' ever since I saw Tea posting about it in the Lurker thread. I can attest to it's increased smoothness and efficiency.

My settings are:

-160PSI
-4ms dwell
-1 1/8 turns out

I'm using one 012 o-ring on the bolt guide (closest to the Eigenbolt spacer), all others are stock 015.

I'm now getting around 1 extra pod on my Ninja 50, and a smoother shot. the 160PSI I'm shooting feels more like 120PSI.

I'd like to hear more about this hybrid bolt also. Anybody done the hybrid and compared it against an eigenbolt or boss xsv/infamous bolts?

Read my post and look at Teahouser's pictures, you've got everything you need to know. Go try it out for yourself, all you need is both bolts.

In terms of performance, it doesn't really perform like either the Eigenbolt or the Boss bolt because it has cushioning on both sides of the cycle. It requires a slightly higher OP to operate at velocity, but you can't feel any "kick". As a matter of fact, there's noticeably less kick relative to operating pressure. Also, since the Boss spacer & shock o-ring make the Eigenbolt's maximum sail line up with the holes on the bolt guide better, the poppet can be tuned to use less air per shot meaning greater efficiency.

Well basically by adding Boss's spacer and bumper oring to Lurker's Eigenbolt, you do a couple things:

1)You shorten the distance the bolt travels, by the length of the spacer and bumper oring. This lines up the guide holes with the back of the bolt better, since Lurker's bolt's sail goes in a bit.

2)You increase the tension in the spring. The way Lurker's bolt is designed, it works better with stiff springs, to counteract how effectively it speeds up the bolt. That's why you get the smoothest shot when using the stock spring with a slightly higher pressure.

3)The poppet back cap can be sweet spotted farther in, closer to one turn out, increasing efficiency. (I'm getting almost an extra hopper off a 68/4500 fill.)

[lunatic209]

Cool. I'll have try it out.

[Lurker27]

Kind of wonder if 2 orings wouldn't have similar results, although it wouldn't secure the spring as well. No reason to have to buy 2 bolts for no reason

[old _fart]

Teahouser,

You are getting how many pods? Cold or hot fill?

[Teahouser]

around 1700 shots off a 4300psi-ish fill. so..like...around 11 pods and a rotor?

You mean just two of the shock o-rings instead of one o-ring and the spacer?

Aside from lining up the sail with the guide holes, does the delrin in the spacer absorb the bolt's force as well as two rubber o-rings would?

Does not really work. The o-rings tear up pretty quick and they try to climb each other and bind.

[Lurker27]

Makes sense - One would need to be at least 90 duro. I'll order some stuff from mcmaster to play with about it though.

[blueshifty]

Sorbothane is really the most ideal shock absorbing material. I may do a little research and see if I can find a suitable front bumper for the lurker bolt.

A square oring is also better than 2 stacked orings.

[Lurker27]

Actually now that you mention it I have the perfect size (016) of square orings already from my GEO bolt prototype, and mcmaster makes the perfect PTFE piece to back that up: 9560K49

Will definitely be testing this, but seems pretty straightforward since this is exactly what o-ring backups are designed to do.
