anyone ever lightened the rear hammer to reduce recoil? I'm building one and I just can't get over how much moving weight there is in it.

before I take this this to the lathe and mill to reduce the weight just thought I'd ask if anyone has done the same?

Pics would be great.

The newer ACS ones are fairly lighter than the old ones, ive seen them reduced before just make sure you have enough weight or a spring kit to open the valve

Engler Customs (http://www.englercpb.com) makes a lightened rear hammer with a self lubricating finish that doesnt require you to toy around with springs.

Yes we do. It is a drop in part. The hammers that come from tippmann are really hard and eat up normal drills.

I couldnt find it on the website... and I work at a machine shop.

that looks exactly like what I was going to try

Thank you

IIRC Tech-T made a very light hammer for a while. Dieted stainless steel, swiss cheese milling, over a delrin core. From what I understand they had an ACS-compatible model in the works, but I'm not sure that it was ever actually made.

**Keep in mind you will want to install an LPK to balance your setup.

holy crap I have AO community members helping me on a tippmann build... whats a LPK?

[Thompsonshooter]

low pressure kit

[Jedihippie]

why would I need an LPK to balance it out, will it not work well without one, is there anyway to make my own LPK?

If you could ever find one

Jedihippie, you can check out model98.org for write ups on how to build your own LPK.

If you do it right you may not need an LPK to balance the set up. You should be able to just change out the main drive spring to balance it out. I have heard with the Techt Zero Kick Hammer all you need to do is install a different spring.

The LPK was really designed to make the 98 a little easier on paint. Instead of it being a high pressure low volume system it becomes a lower pressure higher volume system.

Stock 98's and A-5's use between 700 PSI and 900 PSI, basically whatever the tank's output is. If it is a CO2 tank it can get up to 900 or even 1,000 PSI. If it is a compressed air tank it is getting whatever the reg puts out. That could be between 750 PSI on a PMI reg to 1100 PSI on a Ninja SHP reg. A 98 or A-5 equipped with a LPK operates around 350 PSI. The valve for the LPK has more and bigger flow passages for the air to make up for the lack of pressure. In order for the marker to have enough volume to function properly at 350 PSI they added the volume chamber. If you want a more technical explanation I am sure you can do a search to find one.

You don't really need the LPK if you want to lower the operating pressure of your 98. You could just slap on an inline regulator that can has an output of 800 PSI and adjust it down to 600 to 700 PSI and your marker with function just fine. I have one 98 that can get down to 500 PSI without a LPK, but it can have recocking issues at higher rates of fire so I leave it around 600 PSI. I have another 98 outfitted with Cyclone feed and Response Trigger that functions flawlessly at 700 PSI.
