Hey guys, I've got a suggestion. How about one of you QB tuners offering a turned down bolt handle and a better machined breech (one thats contoured to fit the C02 tube better). I own one of the large knob brass bolts, but the way it sticks out is very unflattering. If a turned down bolt handle were offered I'd jump to get one and I bet alot of other QB owners would also. Same goes for the breech. It would be great to have a better fitting breech that maybe floated the barrel. This way the barrel band could be eliminated, and POI shifting would be greatly minimized.
Don't think I don't appreciate the stuff that you guys do for the QB, quite the opposite. I feel you guys are the only ones good enough to handle this request. So how about it?

Dannyboy, oh Dannyboy!!!!!!
I hate that song and I bet you do too:)
The cool thing about the QB78, and the different variants(I have an AR2078 also) is that although they aren't really all that polished and primed, they shoot really well regardless of the chunky machining...with exception to the barrel band, but you can find aftermarket bands too(RJMachine) and also there are 15mm metal bands available in stock form (archer airguns). So they look all funky sometimes, and internally they definately benefit from a good tune, they are pretty good shooters without much aftermarket "pretty things" added. I think a couple people have been working on .20 and .25 cal mods, and there's some NICE stocks out there, muzzle brakes are easy to find. Archer sells a couple oversized bolt handle things, I just polished my stock handle...oh and then there's also that snazzy safety switch that Art at Artshack makes. Obviously not as many things out there as there are for the Crosman 13XX and 22XX guns, but there's a few, and the other stuff imho just isn't worth messing with. BTW, you can float the barrel as-is.

Who is this Art at Art-shack you speak of, my QB master? LOL! No, really who is he? I looked in the mall but didn't see a link. I've got this twisted idea for a custom QB, but I don't know if it can be done. I'm thinking chrome plated everything (all the metal), leather covered stock fastened with brass finishing nails, adjustable butt-pad, shrouded or a nice MB on the barrel. A turned down, fancy chromed bolt handle. It would be kinda like a Harley tribute QB, get it? I know that the QB's are inexpensive guns (I own two), But look at yours- its fantastic! I've always been one to try to make a silk purse out of a sows ear, so this new QB idea might be the next stop. That is if its possible to do the things I'm thinking of.
Oh yeah, BTW, I really hate that song! LOL!

Hi Danny, We suply brass bolt handles for the QB on request, a couple of pics below. Is that what you meant?
Also I'm not sure if the alloy on the trigger case would take chrome but I reckon the rest would ok.
Sorry about the pics, my camera does not do macro.

My next door neighbor as a kid used to sing that everytime he saw me, I hated that song then, and still do today. I think the only thing that bugs me more is when someone says,"Book 'em Dano" and giggles like it's the first time I've ever heard it before.
Anyways, enough of my hangups and hurt feelings. The "QB Custom Cruiser", I can see it already. Yuppems, can be done. I think I'll build one too as I have been thinking of doing a "theme gun". Hehe, so wrong, but sounds so cool all at the same time:)
Tonight I think I'll bring the old QB out of its case and see what I have to work with. I have lightly tuned mine, it's a .22 and think it shoots in the mid 600's with 14.3 grainers, it has an Arts Shack muzzle brake http://www.arts-shack.com/index.html and a polished bolt handle. Other than that it's in stock form. Not going to mess with the AR2078, it's "just right" as-is, although I would like to bulk it at some point.
You know as far as the chrome idea, the QB is all steel almost, so you can always chuck anything round up in a drill press and polish it shiney with steel wool, then clear coat with poly spray or whatever.
Ok, off I go!

Ian, thats a nice bolt handle! But... I'm looking to have it bent down, curved, if you will, like a firearm bolt handle. I believe the shape of a curved bolt handle would add to the beauty of a custom stocked QB. Is this possible with brass? I'm working to put all of the ideas on paper now, and then I'll start putting together a list of guys that can do the work for me. Let me know if you can do this.
Thanks!
Danny

Hey Dano...Book'em! LOL! Gotcha'!
Thanks for the link, Art does some nice work! I believe he may be the one to go to for my QB MB needs. I'm still trying to figure out how someone would get the leather tight enough around the stock to make it form to the contours. I've got lots of planning to do, but I'm gonna' follow through with this idea and see where it takes me. I might have to sell something, but in the end it'll be worth it!

Hi Dan, I told Jon, the guy who makes the bolt handles for us, amongst other things, says he in a "muffled" voice ;) I believe he now refers to them as LDCs as in Lead Dust Catchers, that they should be bent, but in honesty I'm not sure what the angles will do when the bolt is moved forward. Yes it will cock but the stresses will be different. May have a play with a piece of steel.........
And Dan, you KNOW who is playing with .25 QB's ;) figures soon, I hope and if you look very carefully at the gas tube in the second pic you may see something different about it?????????.

Hello Danny boy, so your into leather hehe. Anyway I do aliittle leather work , check my ( Work to hunt post) I made the deerskin pellet pouch , I've found that to get leather to form good, nows here's the scary part, I would soke it in water. :o Water softens it up and forms well and when it dries ,it shrinks aliittle making a tight fit.Depending on the thickness, the thicker the leather the tougher the fit.Deerskin works good for me, thin and workable. Good luck. Ed

Hellooooo Ian! Thats what I'm talkin' about! A piece of steel, rather then brass. If steel is used I don't think that stresses on the handle will be a worry. I noticed the tube in the second pic, but forgot to ask you about it. Is that a PCP QB? The .25 QB sounds like a winner and should be deadly on any small game one would encounter with it. I prefer .22 myself, and use 21.0 grain Kodiaks in my QB for hunting squirrels out to35yds. My QB is deadly with these pellets, but also likes the 14.3 Accupells.
I'm piecing all of the ideas together, so if you say you can build what I need, I'll be contacting you very soon. I'll be putting something up for sale here soon to get some more $ for this project.
Thanks!

Hi Danny, what you should have asked "Is that ANOTHER PCP QB?" the answer would be "yes!". It's our next generation PCP, shooting now but still in development. See my gallery for the earlier type with the big gas tube. That rifle is getting my next .25 conversion, time I had one too instead of just selling them.
I'll look at the bent steel bolt, should not be a problem and if done properly will stop the bolt damaging the gas tube as it does on some rifles.
May be a long way to ship kit but if I do it and you want it then no worries :)

Hey Danny, I think this is the sort of thing you were asking about. Steel shaft, ally "ball" and bent so it does no damage to the tube or the wood when you use it. Feels more comfortable in use too.

I have made a few straight brass ones as I supply IJL. I have an idea how to bend them without marking the polished finish and will have a go in the week when I have time. Does anyone know how brass bends when heat is applied?
Jon

Jon,
You don't need to heat the brass. With a large radius bend like that, it will bend fine. (unless you are using CAST brass)
If you heat it it will aneal, not good for this application.

Thanks Tom and a big Welcome to the GTA..:) I was waiting for the answer to Jon's question and you have itched my scratch..:)
Thanks for sharing

Brass tends to work harden, so you bend it, and if it isn't right then you heat it.....then it's soft again till you bend it again, then it's hard again. I'm not real great at explaining it, but basically you can bend it all you want cold, so long as you anneal it in between to resoften it. Everytime you rebend it you will work harden it. Back in the days before me copper (brass is copper and tin I believe?) tubing was use in aircraft hydralic and fuel systems because it was easy to route through the airframe......which is a great feature....unfortunately as those systems are pressurized and depressurized, and the airframe flexes, vibrates, etc....the tubing would work harden and eventually crack...bummer when your fuel lines crack:) Thank goodness stuff like this is no longer used....like since before WW2!
On a side note the trigger blade on my BAM50 is brass, which is good because the shape sucked...so anneal, bend to shape, done! Easy way to tell when you've over work hardened something is when it cracks....be careful!

All that depends on what alloy you have. There are many brass alloys. It is not just your WWII brass anymore. My favorite is leaded brass,
Used by engravers and clockmakers, my profession for 30 years. The brass typical in these bolt handles won't work harden that quickly.
If you wanted to bend it into a hairpin, that would be a problem. Cast brass is a big problem to bend. It usually will bend a bit but will likely break if you try to bend it back. Then you have shell case brass, a pain to machine unless you aneal it first.

Good deal, my metalurgy classes were a long time ago and mostly forgotten. I probably know enough at this point to be dangerous:)
Clockmaker eh? Man that is some intricate stuff, wish I had 30 or so extra years to start learning that!!! Have any pictures of past work for us to drool over?
Dan

I had a heart attack and quit clocks about the same time, about three years ago. When I quit something, I do it right. Don't even own a decent clock now. Don't even wear a watch ;o) Now I just work as little as I can get away with . Mostly making tools for clock and watchmakers. Nothing special.
I have started playing with air guns as it is harder to find places to shoot power guns now. I do like the QBs ;o) Just got a QB1 that I am adapting to paintball tanks.
