First Notos major modifications

[kbstingwing]

Ok, so I decided to make the Notos a Bottle gun, I found a drop block on Amazon and made it work for the Notos, I really didn't do much to the drop block, I removed the main valve assembly and the bottle adapter from the drop block, I used a 16 x 1 mm tap and tapped the threads as far as I could on the drop block gun side, I just made a valve depressor pin, I used a 4 x 20 mm screw and cut off the head and ground it down to about 14mm long, I then Tapped the small center hole in the bottle side the same thread as the screw, this will provide a valve depressor for the paintball type regulator on the Carbon Bottle, then I shaved about 0.003" off the drop block gun end, just enough to align with the main body, installed a 16 x 2.5 mm O-ring from the parts kit that came with the drop block, I used a lathe to shave the block, I'm using a 500cc /4500psi carbon bottle, the diameter of the bottle is 61mm, length is 11.75" from regulator bottle connection to end of bottle, I switched out the regulator O-ring on the end to a larger O-ring 14 x 2.5mm, I also added a 20 x 2.5mm on the regulator neck, the drop block fosters fill port is going to be unused, tape it and cap it off, install a Teflon seal into the gauge port and install the Gauge, the bottle gauge and fosters fill port should line up on either side of the barrel, reassemble the gun, leak test, make sure to cock the gun before filling with air.

drop block:

I have only did a few shots to sight in the scope, getting to dark to check FPS, my regulator is preset to 1500psi, I filled the bottle to 4500psi,
I will be testing everything tomorrow.
here's what it looks like

 I'm not sure if you are aware, but this severely limits your warranty Looks great, I was going to say I will be waiting for a shot count to empty, but may not live that long

Kevin! Awesome mods! You should get at least a thousand shots now 🤗! Ha! Nice work!

Oh No, I forgot about the Warranty......  , Oh Well, I guess I'll have to fix it myself if needed, I'm guessing on the shot count being about 250-300 shots, my Gauntlet has the same bottle and about the same tune, and it got just over 300 shots, I lost count.... , weight wise feels about the same, maybe just a couple oz more than stock, I'll have to find my scale to weigh it, tomorrow will be the day for testing, so we'll see.

Thanks Randall, I don't think it will be in the Thousands but several hundred will be adequate for me...

Nice to see you get it all done, takes the notos to whole new level.

It was easy too, the drop Block is already 95% there, just trimmed about .003" off the gun end of the block for alignment to the main body and then tapping the threads on the 16mm x 1mm hole more the the regulator Valve depressor screw, a few more O-rings and done, just getting the tools to do it takes a little time.

Very nice, so the big question is how much you going to charge me to make me one of those lol.. 

[tennx]

Many Props for the build and Im sure it serves u well….but I dont understand increasing the shot count ,when u still have to load it and I havent seen a 300 round Mag….your gun/your rulz….good luck

That is the next thing, just screw a tin of pellets to the mag and shoot away

a 300 round mag..... Hummm , it's all because I'm Disabled, I want to have a gun I don't need to air up as much, like most of my guns are bottle guns except my HW100's and a couple other exceptions which might get converted some day, having to reload pellets from a tin is easier than lugging a buddy bottle around with you to refill, I do a lot of shooting at my friends property and I go through a lot of air and pellets, last time the Notos ran out of air and I had to walk back to the truck to refill, I was several hundred yards from the truck, for me that is hard since I have Sciatica, I have to carry a small chair with me so I can sit and relieve the pain every time it comes on and I carry my Primos Tripod too, so hence Bottle gun now, I also use the tripod as a cane, which helps a lot, I don't want to need a vehicle to get around, I need the exercise but I don't need the extra weight of a buddy bottle hanging on me or walking back to the truck every time I need air  :'( :'( :'(

now Who's going to make the 300 shot Magazine....

[kbstingwing]

Ok, Yesterday as I was finishing the Drop Block, I was also Printing a Moderator Baffle on the 3D printer, it was doing great, 9 hours on the printer 80% done.... then disaster
the Baffle came loose from it's bond to the build plate and went haywire :'( so this morning I went back into the program on Cura and found the problem, I set the build plate adhesion to "Skirt"..... for something this tall, "Skirt" doesn't work... DUH so I went back in and deleted the file and made a new Cura file, reset the build plate adhesion to "Brim", Started printing again this morning and we will see if it worked later this evening, now I need to do some testing.

I'll Be Back

Hey Brian, you don't need a Mill or Lathe, if you have a belt sander it will work, all you need to do is take off just enough metal so the block will align with the main body of the Receiver.
also you would need a 16x1mm Tap and a tap to fit the screw you would use for the regulator valve depressor, I used a 4x20mm screw but a 6/32 screw and tap would work just as well.
the problem is having to have your gun to align the block, I'm sure they don't do every gun exactly the same, were talking china here, so small variants could make a huge difference in the alignment.
besides, I don't want the Liability, doing it for myself is one thing, but for others is another, especially dealing with a high pressure part. Got it...

good luck
Kevin

Ok, I'm Back,
First, I shot the Notos with a 1500psi Regulator and averaged 673 fps with the hammer spring adjusted to full spring tension shooting Hades 15.89gn, I was expecting some loss in FPS due to lower plenum space with the drop block, I switched out the regulator to a 1800psi that I had on hand for another project, that bumped up the gun to 730 fps, which is good for me, not sure how many shots yet per fill, it's gonna take a full day to shoot this tank down, I did weigh the gun with Atlon Talos 4x16x42 scope, it came in at 7.1 lbs, not to bad, it is still really accurate, hit the knots on the tree dead on center every time at 25 yards, there was a Squirrel that ran off just before I sighted it in again, to bad, he could have been the first test subject..... ,

so it works, maybe hogging out the block might increase plenum space, maybe later.

Too much talent, Kevin sir 👍

Gotcha may have to pick one up and play around with it.

[Back_Roads]

 LOL looks like I need a Notos, a drop block, and a bottle with a reg or my head examined ')

[kbstingwing]

Thanks Richard, just Backyard Engineering at it's finest....

Hey Brian, the drop blocks are cheap enough, even if you mess up it's not a major loss, just sand a little at a time and test fit....

Hey James, you might just need one of each.....

[Firewalker]

I followed Kevin's lead and bought the drop block and stripped it down, turned off .005" so it would clock properly then tapped the block for the Notos male fitting.

Not very hard to do and if you are willing to sign a "Hold Harmless" affidavit and send me the parts I need, I'd turn the block and tap it.

I have 4 Carm magazines, 48 shots total, I reloaded them 4 times and still had 2300psi down from 4250psi filled.

"Why the heck did you do this?!?" Cuz I love to tinker, it was WAY cool and now its an all-day-shooter instead of a 2 mag shooter.

My CF .43L bottle weighs 12oz, the steel tank on the Notos weighed 10oz, my reg and dropblock increased my overall weight by 8oz.

The AEA Carbine is now for sale, no need for both and since the Notos groups 1/2 the group size, its a no-brainer!

[Firewalker]

UGH! It wont post correctly!
