Initial review of the H.B. MACHINE fluted hammer

Not complete, but here's what there is.......

H.B. MACHINE fluted hammer

Very succinct and to the point.  >

am i missing something? what dose a lighter hammer do for u other then require u to use a lighter spring?

I'll have to add to it a little at a time. If I try to do everything I wanted to, it'll never get done. The first thing I'll do is just tune a stock CCI bolt, get some readings, and then just drop in the fluted bolt and see what the difference is. My hope is that this be the perfect and easy solution for those that like to play pump at night, but don't like messing with the bolt/set screw to chrono lower.

That should help point me in the right direction with using different springs. I want to use the CCI spring set which only gives you a choice of different valve springs. That's makes perfect sense with the TPC being adjustable. A variety of main springs with an adjustable bolt is just redundant and confusing the issue IMO. I also want it to be something that everyone could easily do, and the CCI springs are readily available.

Then I'll start messing around with valve volume to try and get 60 plus shots from a 12 gram! 

Nitro,

A lighter hammer can help make the valve work more effectively with the right spring combination.

Terry, you're backwards. CCI offers three different main springs and only one valve spring. Seeing as how they are much easier to change, and don't require degasing the marker. Each spring has a different range of adjustablity, though there is probably some overlap too.

[thkyle]

You are right. What's what happens when you need glasses!

Maybe I'll have to try a set of Maddman springs? I have a big pile of old springs, but I wanted to use new ones, and something that was still available for testing.

I'm looking forward to hearing more about this I have a nelson fluted hammer coming that I planned on trying out in my Gargoyle to see if I could get 60+ on a 12ie.  Odd that we both picked that number.

[Nitro]

ok i still don't get it... if u need X amount of air to get a ball to leave the barrel at Y speed how is a lighter bolt + "right spring combo" going to make u use less then X air if X is the amount of air needed for Y speed?

if your not changing the presser of the air u are still going to need volume X right?

Roughly, but changing springs and mass allow you to modify the impulse of the system.  The more quickly you can open (and close) the valve on a paintgun, the more efficient you can make it.  Of course, there's other non-efficiency reasons to mess with hammer mass and springing - cocker owners were all about super heavy hammers and super light springs for a time in order to minimize LPR pressure (in an attempt to keep from chopping paint).

[super_stanchy]

is this a mass produced hammer....

or is it somebody who was bored in a machine shop?

just curious

[Chefdave]

It's a prototype hammer produced by an innovative (and probably bored) Have Blue.

[Have Blue]

The hammer is just a CCI hammer - I simply introduced it to the milling machine.

Mitch has done some pretty extensive testing of the hammer and finds that it's getting him about 5-6 extra shots with no other modifications to the gun.  I'm considering that to be a 'win', so I'll be proceeding with the project.  I do need to decide on how best to re-plate them, as the bare steel surface starts getting a tinge of oxide over time.  Thinking of going with a Teflon impregnated nickel just for 'oooh, aaah' factor, and who knows - maybe it will actually help a little.

Found this link to a review of an old Lapco ultralight hammer from many years ago:

http://www.geocities.com/bz456/lapcoph/lapcoph.html

I got my hands on one but haven't tried it yet. Weighs about 28-grams with sear.

I hear there are over half a dozen variants: steel, brass, fluted, non, short, normal.

Of course those are all out of production and difficult to find. It would be great to have a current source of performance hammers.

It hasn't been said in this thread but would a light hammer have less tendency to bounce than a heavy one, all things being equal?

[Chefdave]

Yes.  A light hammer has less tendency to bounce.

[super_stanchy]

hmmmmm what if instead of makin a + shape design.... you make it just 2 or 3 wings?

wouldnt it be even lighter? or would it not be beneficial?
