Umarex Notos bottle source?

[Firewalker]

It's not timed quite right but I dont really care that it's off to the side some as long as there isn't a leak

As long as your happy with the severely weekend joint....

No, there is no space inside that one, just an air channel.

Thanks Firewalker, I am checking out the Huben Power site: https://shop.hubenpower.com/products/huben-power-umarex-notos-regulator-ultra-stable-output-pressure

Why is it weekend that way it's tight or because of be side ways some

The threaded portion of part 66/air block is thin walled, it can withstand straightline forces but with being cantilevered and holding the weight of the drop-block and bottle, it's one good jar away from severing of fatiguing.

An adjustable plenum with a large cross-section bears that stress instead allowing for a safe conversion.

It depends on how the reg is placed in the block

Thanks Airgunmann.

Good to know thanks I will fit it properly since I'm looking for a airleak any way

You are very fortunate to have had a perfect fit! I've fit over 80 of the Crickets so far and I have not found a single one that was threaded to match the clocking on part 66/the air block.

I've got 2 Cricket regs and they both turn about 120 degrees (about 20 analog clock minutes) on two different Notos's too far to fit tight onto the Notos block.

So to get it to clock straight down I need to get rid of about 0.9mm. (it needs to turn 240 degreees further) don't know what the thread type is so I could be off on the 0.9mm, I did a quick measurement i.s.o. a threadcalculation)

Unfortunately I don't have an end mill (nor a lathe) so sanding that much off is more or less out of the question I think. And the oring recess will be .9mm less deep then as well, not ideal...
For now I have some 14mm and 16mm bonded washers on order. Hopefully that'll do it when they arrive... (tried to fill the gap with bigger oring and such, but that starts leaking prettty fast as it is not contained)

Does anybodyhave any other possible solutions maybe?

I’m not sure I understand what you’re comparing there. Do you have a picture of an adjustable plenum?

Use the plenum by c88machining on eBay. It has an inner and outer barrel, just unscrew it a full turn before installing the Cricket then snug up the end on the guns air block and turn the Cricket until its clocked correctly.

Add your bottle and add air. The air pressure will lock the plenum where it is.
