and even looking at deeper into the equation you're not going to get any less kick than you can get from an MQ cocker only because you cant reduce the mass of a paintball.

while the concept is feasible,

the blowforward concept is simple at its best,
but a spring would do more wonders than an electro coil.

I'm all for simplicity, but MRKR killed me at the micro switch part

I am thinking that this is a very strange form of a troll. The man made a new profile and his post is thinly veiled nonsense.

I think it might work if you had balanced magnets (non-electro, strong earth ones) that were on the front edge of the end of the bolt rather than the backside and had counter magnets in front of those magnets, the operation would have to be very small and be perfectly balanced so that there is even resistance with the contrasting pulls so that bolt wear isn't a factor and magnets don't slam into each other. But in reality you would have to be running super low pressure, probably below 60psi because the response of the magnets wouldn't be quick enough or stable and consistent enough. If you could get over that hurdle then it might work.

Using electromagnetics is very expensive and wearing on batteries, so I would steer clear from that.

sorry I just picked a random gun that everyone said had hardly any kick. in alot of these guns that have extremely low reciprocating mass the only thing making kick is the mass of the paintball flying out of the barrel. shoot you gun a bunch of times with no paint and then drop a ball in.

I know what you're saying, you're just not right. It's relatively trivial to design a system that has the benefit of mitigating kick due to the paintball or has a method of canceling out that kick...In fact, I have prototypes of such a system in a DM4 right now.

Also, I'm giving you a hard time because you said that engineers don't have common sense. You're not in a position to be talking down to people more qualified than you. Your posts are consistently off topic with poor punctuation and spelling. I'll stop short of lecturing you but please do reconsider your posting style; I'm a very tolerant person and you really do drive me in to a murderous rage more or less every time I see your avatar.

Cordially,

Lurker

Well you could mitigate the kick but to do so would either require reciprocating mass that doesn't do anything besides mitigate kick. Or you could be a complete and total genius and design it so the reciprocating mass and make the timing so perfect that it does this. I was only saying that there really wasn't any way to reduce the kick from the internals much more.


Hey at least my spelling has gotten better since I switched over to chrome from ie.

edit: while I do respect your knowledge (looked in your sig)
the fasor concept does not fit this markers supposed style of operation.

while it does share a basic similarity to spool-esqe' fasors (something im working on)
it isnt driven like a fasor.

i believe a blowforward spool would better suit the workings of this concept.

on the order of "ok let drill holes all in this aluminum frame to make it lighter and then put a quarter inch steel plate on the bottom to make the frame stiffer."

anyways is there any more news from the op as to if he's really gonna try and make this?

I'm guessing no...

To comment about mechanical engineers. Most of my colleagues at the college I transferred from were tight wads fo shizzle. I was prolly the most outlandish in design mentality, however it was mostly because everyone else would use prefab'd parts, and I proved you could make them, and consequently, make them better. Was it a tad bit more complicated for a single piece? yes. was it a bit harder to trouble shoot? yes. Did we win the contest with the most efficient and fastest design? also yes However it was weird because winning at school in a contest with your colleagues is usually a lose/lose situation because even if you do win all the other kids are jealous and make fun of your teams name which is an acronym, and instead replace it with homosexual innuendos, and if you lose you still lose lol.

My mentality has always been don't be ashamed of complicating things... If in turn they improve efficiency and speed.

I like your idea. one way that it could be done is by making the bolt out of something slick line nylon or delrin, then at the end of the bolt attaching a neodymium magnet to make the magnetic return much stronger and faster.

Although these issues come up
-the battery life would be much shorter unless you used a lithium polymer battery
-with a neodymium in the gun you would have to be careful holding it around certain electronics such as computers

rare earth magnetics would be an even better choice than neodymium, they're the strongest magnets that i know of besides electro.

make it a pump. This will solve your bolt return problems.
And make the bolt extremely heavy, so that when it flies forward it will counter the force of the release of air, causing minimal kick. Also make it autotrigger-able, so that it has a market.
