Very interesting idea.  This morning I sent him an eMail asking to buy two units.  Hopefully they should be here next week when I return.

Good ol' Steve in NC is really doing everything he can to discredit the work Steven has done.  It seems that this new device might take some of his revenue away from his partnership with AoA.

Personally, I'm loving it after the attack he and his cronies rendered upon me and the SHD  ;D   But just to be fair, he does seem to be a smart fellow and his Maraurder HDD should be reliable and long lasting as it applies (or is it steals) an age old braking theory, it's just a lack of  social skills that holds him back from being one of the greats in our hobby. Uhhh.....did I just say that?  ???

What I would like is a device like a nitro piston to replace the hammer spring.
I find the vibration more annoying than the loss of gas from a de-bounce.

It may kill two birds with one stone meaning it will only fire once and not bounce?!

Anyone?!  ;)

I assume the hole is for the hammer pin, Carl.

Does the O-ring act as the brake so when it rebounds the o-ring rolls along the tapered edge to stop the pin bouncing?  ???
Title: Re: another hdd
Post by: quickster47 † on November 17, 2011, 09:15:39 PM
Yes, hole is for the hammer pin.  And correct, the o-ring rides up the taper and puts the brakes on.  That is the theory behind how it is supposed to work.  Will know more tomorrow.

hey there ya'll,

i'm very interested in this  hdd. looking strictly for increased shot count, anything else is gravy.

certainly do not want to spend money on the delrin junk that someone else is selling. already been burned by that person, not going to happen again.

don't know about anybody else but, i have to be careful about my airgun expenditures. 20 bucks isn't going to break the bank, but i'd hate to waste the moolah. :-X ;)

looking forward to your reports and thanks.

Carl

Yes, a bit of testing on the inventors end. I made them and sent them on to him. We were just about to make a couple of adjustments, shallower taper and v-cut the delrin ring so that it would be guided by the hammer pin and also open more as a result of his testing when all of my family started to fall apart. Family first, so it was just a matter of time before someone else would build a better mousetrap and I do believe that by using the o-ring, it may have been the crowning tweak.

The picture I have says May 28th. The one above had to be re-saved to fit the 200K limit here on the board, so that one is dated yesterday. But hey, I am not sorry for me, only the guy that had asked me to make it for him. Had I been able to continue without the interruption of the inevitable circle of life, he might be making 20 bucks a pop and not someone else. I do however wish him well as it was a good idea (at least I thought so) or I would have passed in the first place. I just hope it works for all of us.

Post by: quickster47 † on November 18, 2011, 02:34:37 AM
Rich, I've read good things about it but we shall be seeing first hand tomorrow.  Like you, I also look for the gun being quieter since the hammer should not be bouncing all around and burping the valve.

Carl
Title: Re: another hdd
Post by: quickster47 † on November 18, 2011, 10:59:02 PM
Okay, took some time out of my overly busy day doing stuff that retired folks do and that would like my wife says, "What did you do today?" and I reply "Nothing."  She then says, "I thought that's what you were doing yesterday." I answer her by saying, "That's right but I didn't get finished."  ;D

Anyway I fitted one of the new HDDs to my basically box stock 2240.  And when I say box stock I'm talking about the internals because externally it has a long steel breech,  a complete 1701P/Marauder pistol trigger frame, a 2300S rear velocity adjuster I've been playing with, a brass muzzle brake and bolt handle from local CAPOF member arkmaker, and a red dot sighting device.

The gun is nothing special, just my workbench workhorse.  Right now it is shooting JSB Diabolo Exact Jumbo Express pellets weighing 14.30 grains and delivering 420 FPS average with 5.6 FPE.  As I said, nothing overly special.  In fact, it might be a little bit on the light side for 2240 guns.  But that's okay.

My HDD testing will be done over a couple of days and was started today.  First observation was what I expected and that is the gun is definitely quieter, and this is a good sign that the HDD is doing what it was designed to do.  Will report back later about the increase in shot count if there is any.

Carl

I think from some of your testing I saw that is what you did so the last time I bought five boxes of 25 powerlets I opened them all up and sorted them by weight.  I did this one night when I was totally bored out of my mind.  Doing this did not help.

Carl,
2 questions...

That muzzle brake looks heavy! Does it make the gun front heavy? I usually fire off a shot or two to see how it sounds. I never did with this one, just forgot before I sent it. How does it sound? Each one seems to sound a little different from the next and since I have still not made two alike, I'm curious.

Post by: quickster47 † on November 19, 2011, 05:10:37 PM
Dave, Make sure you get the o-ring facing toward the back of the gun otherwise the braking principle will not work.

Rich, this gun has a similar sound to the others with HDDs.  This one sounds like a pftttt.  You can definitely tell the HDD is working by the sound it makes.

Most interested in how it holds up and if my shot count goes up.

Yep, the muzzle brake is a little bit heavy for this gun but so far it hasn't effected my shooting.  This set of plastic grips has also been filled with liquid metal and that gives me a better balance.

Leave the end cap off the breech. It should cock.

The HDD is just long enough to require that you remove some of the end cap material. Not to the screw hole, but some amount.

Good point Larry.   :)  I guess I've been using them so long that I forget about some of that stuff.  I also went to Lowes and picked up some 1/4" black plastic plugs and use them to fill the hole.  Although not necessary, it does clean up the rear of the gun.

ok, what does HDD stand for, and is this something I have to have? 

I know I don't have to have anything, but here is why I ask.  I have a BOSS valve i put in for more FPS, but t's eating my CO2.  if I used one of these, would I increase my shot count, and keep the FPS?  And how are we supposed to remove a portion of the end cap?  Are all airgunners machinists?

HDD = Hammer Debounce Device

So why is a HDD necessary?  Well, glad you asked that.  The problem with the Crosman 22xx CO2 guns is hammer bounce (repeatedly hitting the exhaust valve, releasing small burps of CO2) and that wastes gas.  So anything you can do to keep the hammer from repeatedly striking the valve will improve (lessen) the CO2 usage.  Therefore, less CO2 gets wasted when the hammer isn't bouncing into the valve multiple times per trigger pull.  The design of the HDD for Crosman pistols allows the hammer to fly forward without any drag, but as soon as it starts snapping backward the HDD expands against the walls of the bolt bore and brakes it.  This stops the hammer from opening the valve multiple times as it bounces back and forth between the hammer spring and valve spring tension, which obviously just wastes gas.

The HDD fits over the hammer's cocking pin, with the slot/opening facing backward.  The opening/slot is what makes the device expand; the hammer snapping backwards makes the pin attempt to back out of that opening/slot and makes the body expand in the bolt bore, creating friction to slow the hammer.  Forward motion isn't restricted though, so your shot velocity remains unaffected.  You just get way more shots per fill since it isn't re-opening the valve after the pellet's already gone.

It's also worth mentioning that the gun is a lot quieter with the HDD installed.  I actually shot a string with the HDD installed first, and then took it out to shoot "without HDD" string.  The gun sounded like a cannon after I'd gotten used to the quiet volume of the gun with the HDD.

Hey Carl,

Are you planning on trying the HDD on multiple aftermarket breeches?
I'm guessing they all have slightly different variances in the bolt tube diameter and I'm curious if there is an optimum combination with this HDD or if one with a tighter fit would cause issues with its function. 

I'm mainly curious on how well it works with a Cothran breech.  Figured it might be an interesting additional experiment.  ;)
Thanks for taking the time to post your results.  I'm finding it very interesting.

Title: Re: another hdd
Post by: quickster47 † on November 22, 2011, 01:57:37 PM
I do happen to have a Cothran breech laying around so Imight just give it a try and see if there is any difference in the way it works.  Think I will also send Steven another eMail and ask which breech he used for his testing.

Good point Mr. Slothart.  :)

I'm still shooting my 2240 with the HDD and might be getting close to emptying my first powerlet.  Shot count so far is about 50.

I'm all ears and reaching or the pocket book.  However, I need to know if I have to modify the rear cap in order to use it.  If I do, I'll have to send someone my cap or take it to a machinist.

You can do without the cap.  It is only there for cosmetic reasons and serves no useful purpose other than aesthetics.

Title: Re: another hdd
Post by: JEBert on November 22, 2011, 08:48:04 PM
DP,
If you follow Carl's advice and take the rear cap off, send it to one of us and let us grind some off of the front of it.  I will do it for you but I don't have one of those HDD's so I will need to know how much to take off.  I will have to use a grinder.  One of these guys that has a lathe might do a better job but they might want to charge you something too.
Cheers,
Jerry

again I am an idiot....this piece goes in the breech, not the air tube.  I don't have a cap, and at some point I have got to stop putting money into a free gun I didn't need.  But at this point it is my favorite gun.  My QB-57 is pretty sick, but it is not as easily wielded as the 2240.  Sounds like I can just toss the HDD in there and be off to the races.  Thanks guys
Title: Re: another hdd
Post by: quickster47 † on November 22, 2011, 09:53:10 PM
Here are a couple of pictures.  One is the breech and the opening in the rear.  You can see the screw that passes through the breech.  The other picture is the metal plug that comes with the Crosman Long Steel Breech kit.  If you add an HDD and use the Crosman breech you can NOT use the plug unless you trim it.  If your breech had no plug you are good to go.

I ran through a powerlet on my 2300KT this afternoon with the new HDD. I saw a slight decrease in pellet velocity (-12 fps), but very minimal change in shot count (+4). So far, this device is neutral on my gun as the numbers were much like the 2300KT without the HDD. I still have a few things I want to try before I make a final statement, though.

And here is a pic of the Crosman steel breech end cap that has been ground back to the thru-hole. Grinding seems to be the easiest, because it would be hard to hold in a lathe because of the flange. If you wanted to use a lathe, you could always make a split arbor, but since it is a 3 minute job at the grinder vs making the arbor, I chose to grind. If I had 20+ to do, I would make the arbor. Anyway, grind back until you are close to the hole and you will have enough room for the HDD.

Great way to do it.  I used a drill bit through the screw hole to hold the thing so I would quit burning my fingers trying to hold it.  It also worked out as a good heatsink.

I just put mone in my 2300T yesterday, and I have a hell of a time cocking it now.

I guess I'll take it down and grind the plug down.

If it only gets four more shots per powerlet, it is not a worthwhile upgrade, IMO.

You can also just leave the plug out for your testing because it is only cosmetic and serves no functional purpose except to plug the hole.

So, normal shot count with a FPS range of +/- .5-10, per powerlet on a stock 2240 is around 35-40. So, if a HDD gets you 50 flat shots, then every 6th powerlet is free. (of course, that's after recouping the cost of the HDD). Add to that the benefit of less noise and fewer physical powerlet changes and I see it as a win....

Does that sound right?

I also don't remember using a HDD that I got any kind of FPS increase, nor did I expect one.  That is not one of the things the HDD is supposed to help/improve.

No, sorry for the confusion. That was not what I meant. I was talking about having the shots stay at a consistent FPS until the cart went phooey and the FPS dropped off the face of the earth. Point was that even if you only pick up 10 good shots per cart with a HDD installed, you're doing good. Should have just said that to start with. Sometimes (usually) I use to many words.

Apologies for the confusion.  :-X

Actually my post was not directed toward you but more to the general public that might be expecting a FPS increase from using the HDD.

i just got one of these things yesterday from Smaug here. i can barely fit the pellets into the loading spot with the hollow probe bolt im using. anybody else noticed this?

im thinking of passing it on to someone else who wants it.

you could shorten the rear of the bolt if really wanted to keep it!

Who made the probe you are using?  I have not seen a problem with them if they are made correctly.  And it should not make a difference as to the type of HDD.

Do you have a long steel breech with the rear end cap plug in it?  If so, that could be the problem.  It needs to be shortened or removed.

You snagged it before I could, If you want to pass it along, I'll be glad to mess with it and see if i can make it work.

I'll probably take the 2300T apart again and grind down the rear plug a bit.

If millipede does the same thing, that will create more room.

I've yet to run a CO2 by the chrono and check for improved efficiency. Maybe tonight.

oh yeah, it's a .22 hollow probe bolt made by charles mellon. im using the stock hammer spring too in case anybody wondered

Post by: dpricenator on November 29, 2011, 07:39:33 PM
The holow probe bolt is longer than a stock bolt already, so you probably just need to grind a bit off the back of your bolt.

Same thing happened to me when I had the Transformer set up with the .22 14" barrel and Charlies Flow-thru. Being that the pellets are so big and easier to handle than the .177's, I left it alone. I had enough room to sqeeze then in without ruining the pellets, but if you can grind off a tad, you'll be golden!

Here is Carl's pic that he posted a while back. Thought I might need it some day!

hey there ya'll

been gone for awhile.

there hasn't been any new info on the hdd. that seems to bode not well.  ??? :-X

is it not giving the shot count that many were hoping?

just didn't live up to expectations?

it seemed to have promise but, i haven't seen any further info here or on the green.

does anybody have a low down on what's going on w/ it?

thanks for any thing ya'll can give me. :-*

later

i simply haven't had time to test it. i installed it and chronied a few shots one day but a few days later i realized i had it in backwards   ???   after this christmas rush i should hopefully have time

I've been using one in one of my 2240s but I have to say thus far the results have not been that spectacular.  Can't say that I'm disappointed just yet.

thanks for getting back carl.

yeah, i was hoping that the season might have had something to do w/  not hearing anything. the silence was a bit ominous. hopefully that thing will work out.

merry christmas and have fun.
Title: Update on mine:
Post by: Smaug on December 12, 2011, 07:49:03 PM
I installed mine on my wife's 2300T a couple weeks ago. I noticed that unless the bolt is pulled sharply back, it either didn't cock at all, or didn't cock all the way.

If the bolt is pulled back and it cocks, but not all the way, then it has a hair trigger. Just touch the trigger and it discharges. So be careful guys.

Yesterday, I finally got a few minutes and the motivation at the same time and took it down to the garage. Pulled the rear breech screw, took out the breech plug, and ground down the breech plug to pretty close to the hole with the Dremel drum sander. Cleaned up the sharp edges, put it back together, and was done in 15 minutes. Didn't even need to mess around with that 0.050" front breech screw.

Works great now, though I haven't taken a shot count yet. I put a new CO2 in and shot 22 rounds, and left the tally sheet on the gun, so I'll remember to keep count. (I don't want to blast through a CO2 just to count, and waste all those pellets!)

It is noticeably quieter now. If it ups the shot count by 10 or more shots before I notice it falling off, I'll consider it a success.

It is curious that a few noticed their pistols were quieter after installing this HDD. In my experience, there was no reduction in sound. Shot count was basically the same with or without this device. All in all, this first batch is neurtal on my CO2 pistols. In fact, S. McCann has received very mixed reviews from this first design and is working on v. 2. He said that everyone that received an HDD from the first batch will get the newer design when it is finished.

I would have to agree with you. I noticed no decrease in sound levels in mine.
