We've been working on an idea based on seeing other Derlin hammers and the fact that WGP sells the Lazarus valve so I have a feeling a few of you picked one up like I did and might be interested in what a weight reduction of the hammer could do. This first run came in just over 10 grams and the *very* rough math for it shows a roughly 20% efficiency increase at the valve. The stock ICS hammer and rear cap come in around 42 grams so the cycling mass alone should be significantly lower to say the least. Another comparable hammer would be the Jenny some of you may have personally run which is around 7g so you can expect a cycling feeling similar to that.
Things you should know:
1. only one exists today and we haven't thoroughly tested it. Assuming it works out we'll be making a small batch in a week.
2. Efficiency: This is optimistic calculations at the valve without considering all the real world realities like friction, actual air flow, space monsters, time warps, what Reba Mcentire is doing today, etc. Another way to think about it is that it wont make the entire marker more efficient so expect no improvement and be happily surprised if it provides any for your setup.
3. Spring: we haven't been able to source springs but the spring kits you all already own are about right. The optimal range from the math is 4-5lbf from the spring. Your IVG should be able to get your in range with most springs kits (lower end of spring strength options in your kits)
4. Valve PSI: It's looking like 195psi will be the sweet spot.
5. None of this is tested! I'll have significantly more information once I can get this dialed in and test out actually getting 290fps from it on my Karni.
6. Will this work for a non Lazarus valve? Probably not, let me know.
7. I'm an idiot, assume I'm wrong about all of this 😎
What is it called:
I'm calling it featherweight for now unless one of you fine gents has a better name.

I love ics setups for fullblock cockers. Are you planning on this only using the threaded type rear block or have an insert to use on standard back blocks?
