Opinion on modified hammer

[DireWolf]

Has anyone thought up the idea to remove as much excess material from the hammer as they can(i.e milling and drilling) My idea was to put the hammer in a mill and remove material on each side as well as the top to lighten it as much as possible. Also drill 3 intesecting holes all the way through the bolt between the o-ring and the start of the "spring hole"

Any better ideas on cheap home mods?

BTW, pardon my terms, im still figuring out the correct names for alot of the internals.

-Thanks

The heavier the striker, the more force applied to the valve pin. If you go lighter, you will decrease kick, but you also increase your chance for recocking problems.

Goalie, not really.

Just to clarify, These shouldn't have any effect on valve dwell. The primary reason people had to run harder mains with the DHC was the finish, not the weight.

I think Apoc solved that problem.

Anyway, valve opening time is determined independent of the cyclic mass. (Given constant vlve spring) It is a funciton of kinetic energy of the hammer at the moment it hits the valve, which in turn is determined by the spring constant and compression
(Hookes law, KE=.5K(X^2) )

Given that, kick is determined not by cyclic mass, but by cyclic momentum MV=MV. Heavier markers kick less for that reason. A lighter hammer, say half the stock weight, will move faster because the spring will impart on it the same kinetic enrgy (minus frictional losses, determined by the hammer's throw, which we'll say is constant between strikers, and of course the coefficient of friction.

Keeping that in mind, because of those two equations, the lighter hammer moves faster (more cps!) and also reduces kick due to having less momentum. If it's half the weight, because momentum doesnt have velocity squared, but KE does, it doesn't have to move twice as fast! it only have to move {(root)2} as fast, or 1.41 times faster. You'll see more cps this way, remember. Kick then, is (1.41/2), or %70.5 of the original. Apoc's striker is lighter still, and probably, by itself, will make your marker cycle (in theory) twice as fast, with half the kick. That will be somewhat mitigated by the addition unchanged mass of the bolt, but the reduction should be clearly greater than the less smooth (more losses) DHC hammer.

So, the losses caused by the DHC Hammer were based solely on the hardcut titanium finish, and an investigation of Otter's page shows that his modified Ti striker actually gained him velocity.





All that said, the striker is hardened steel, and machining it isnt fun. The best mods have all been done to my gun, sigged.

Maybe a drill press would work for that.

[DireWolf]

A friend of mine has a small mill that I might be able to use. Otherwise I have a drill press in my garage that will work. The idea is to take as much material out without affecting the spring, oring, or the hole on top for the pin. Once I know that my local paintball shop has a spare hammer, I'll start my testing.

[Lurker27]

Use TiN or carbide, possibly cobalt bits... hardened steel will eat standard steel bits like crazy.

i think every physics class teaches it.. maybe youll learn after you graduate 1st grade keyboarding class :D

lol sorry.. just someone had to say it.. :P

[megabork]

been a while since physics class,,also since first grade ,,you guys will learn as you get older not to take life so seriously as it goes very quickly indeed
