Just curious: Is the 2024 line only available in chrome? CRplus?
H&S 2024 Line

- Start date
CR only at this stage, but they may do the non cr in the future

I think so - it's triple plated chrome. I'm not entirely sure what the squidmar coatings are though, but that's the other option (a mix of chrome, gold plating, and whatever the black is).
Very nice, boss

alright, getting closer to getting my mitts on one of these. Should only be a few days now. I will be looking much closer at what makes it tick.
Can't wait to hear what you think of it.!

very interested to see what you think of the new trigger.
having now painted a few hours across a few days, I think, for my finger, the knurling feels a bit sharp. it does keep my finger engaged and has minimized any slip but I find my finger feels a bit sore the next day after using it.
I'm clearly 'pressing too hard' on the trigger, but that's what feels most comfortable to me based on my preferences. maybe i have some bad habits this trigger is trying to train me to break, or maybe the pad/button is just uncomfortable. otherwise I like the brush a lot.

@DaveG I used the air valve spring, o-ring, and lubricant from your Evolution conversion kit (decided not to reem out the packing seal yet to accommodate the black o-ring in the kit).
the trigger is 1000x better - very very soft and doesn't bother my finger anymore.
I also replaced the trigger spring and was surprised the one that's in the Infinity 2024 looks gold in color (most likely brass?).
After replacement and tuning the trigger spring adjuster, I'm feeling much more comfortable with the new design.
thanks again for your efforts with the conversion kits. Guess I won't have to ship mine to Ian after all.

Either send it to Ian or send all others to me... your choice...

hehehehe, I will work with the brush for an hour or so just to get to know it in stock trim, but it will for sure get the seal and spring change. Everything does (because I spoiled myself). Spring is plated, I am sure.

The Infinity 2024 has landed (Special thanks to Artem and the team at Spraygunner.com for making this happen - love you guys!). Here are some first pictures - the camera really does not do that red justice. Beautiful finish on this brush, for sure.
I have given the brush a once over, inside and out. I spent a little time comparing parts with the previous version, adjusting, and acclimating to the new brush. For me, feels great in hand. Well balanced, and everything just feels like it is right where it is supposed to be. Kudos to them for increasing needle draw without making the trigger taller - the underside of the trigger has a recess for the excenter to ride up into, allowing the top to remain the same height.
After some initial spray testing, I did replace both the stock air valve spring with my own softer unit and the teflon seal at the air valve top with an FFKM75 O-ring. There is a lot of adjustment available in the needle return spring, but I will probably change the teflon packing out for an O-ring anyway - the action is very smooth (I am spoiled with the softness of the o-rings)
I did a quick comparison between the new and old brushes and found I could easily get a finer line at lower pressure from the new brush, which was also easier to maintain versus the older one. I had to up my air pressure maybe 25% to initiate paint flow on the older brush, and had the line frequently break while having to re-establish flow. I used the same paint sample in both brushes, and will work to actually quantify the pressure requirements as I have more time to work with the brushes.
I have a couple of projects already on my desk that I will carry on using this brush on, as to get to know it under actual fire. I will have more as I learn what I learn.

I suppose it looks great at arm's length...

@DaveG - there's some speculation going around about putting the needle set with the new nozzle into an older brush to see if there is a gain in performance.
I can't say I have enough milage to really assess the subtle changes this might bring. If you end up doing this test, let us know what you find.

I will be checking that out... The claim at present is that the new brush moves more air through the body to feed the new nozzle/head combo. I am working on a setup that will allow me to measure the actual flow - in addition to observational testing.

Excellent! I look forward to your findings.

From what I have read, and this is only speculation on my part, the idea behind the switch to titanium (other than a marketing strategy) is to make the nozzle "walls" as thin as possible, reducing the outer dimensions. This in turn can provide a bit more freedom in the design and size of the air cap. The nozzle always gets the attention, but the air cap is the silent hero here. It is what makes it all work together. Too tight a gap, it could be prone to clogging and make concentricity very challenging among other issues. To big of a gap will require considerable more air volume to keep the pressure differential. Air pressure, volume and speed need to be properly controlled in order to get the best performance, working together with the nozzle, needle profile and needle position.
Add to that the complexity of the dual action. You want very little paint at relatively low speeds for ultra fine detail but you also want a lot more at a much higher speeds at full throttle.
Am I getting this right?

Actually, I don't quite understand what benefits "allowing more air to pass through the body" can bring? I think the atomization and control of an airbrush is primarily affected by the combination of the nozzle and nozzle cap. As long as there is enough air passing through the pen body it should be an “OK” airbrush？ (I think even if more air passes through the airbrush body, the gap between nozzle and nozzle cap will limit the speed of the air)? I would like to ask you how you think and analyze this problem ？(my physics is not very good, if there is physics-related knowledge, it may take me some time to understand!) Thank you DAVE！
