Well, I decided to go with online metals, so I tried to think of every piece of rod and tube I might need over the next few years and put an order in :)

Hi, thanks for the link. Unfortunately it looks like all the K&S tubing that the hobby shops stock is thin walled - 0.014. I thought I saw other wall thickness from K&S somewhere, but I'm struggling to find it now. Made more difficult by the fact that most retailers don't even bother to list the thickness. There is at least some aluminium tube in .035, so I could fall back on that if I can't get brass. At least I'm in no hurry, I'm up to my eyes in sawdust at the moment with my first attempt at making a stock. That should keep me busy for the next couple of weeks at least!

Regards,
Jim


I should have told you to wait till Monday! I have lots of brass or aluminum, Stainless or steel at work I could send you. Small bits only!

My order arrived today - can't grumble with that for quick delivery over a wintry weekend. I ordered several pieces as offcuts with random 10 to 12" lengths, all were generously cut. Everything was well packed and the shipping cost didn't seem quite so bad once I had 7+ lbs of metal in my hand. Overall, I'd recommend them as long as you can put together a big enough order to offset the shipping cost. Most of this will go in a corner while the ideas ferment - reckon I have several years worth of fun here :)

Try to find new style breach, it will solve the pellets loading problem. I'm very happy with mine, work flawlessly!

How would the new style breech attach to the body of the gun though? There's no hole on the tube to screw down on. :?

...unless the newer guns moved the breech hole and screw further back?

Ace, I meant no corresponding hole tapped on the main tube that would line up with the hole on the newer breech.

On my 2240 (purchased on 2011) there is two tapped holes, the rear one fits new style breach... Ace is right, screw is under probe.

Well that would certainly be an improvement. Both the breeches I have are the old style, and I don't actually remember if the tubes have the second hole or not. I'll have to look next time I have the guns apart. It still doesn't solve the problem that the channel is too wide for a 177 pellet, so I think there is still value in trying to sleeve the loading tray. I've just about talked myself into leaving the breech screw out. If I add extra set screws over the barrel and ensure that the barrel is well anchored to the main tube I don't think the breech screw will be contributing much. On the 2240 I have the barrel band right in front of the breech, and on the 1377 I'm planning on an aluminium band that extends from the pump pivot and holds the barrel. I'm not so convinced about that one - have to see how it turns out.

I totally get what your saying with the pellet getting stuck on the little screw and having to tilt the gun especially with an extended probe. So i just did this little remedy literally 15min ago with my trusty aluminum tape, now its not as extreme as your plan but it works great no more pellet hang up, if i need to get at the screw just peel the tape off and put another one on, thanks for giving me the idea EverHopeful. :wink:

this is my 2289 backpacker with the extended prob mod.

Nicely done! I hadn't thought of the good ol aluminium tape :) Did you have to take any metal off the bottom of the bolt or was there enough clearance already? That extended probe looks very functional too. I use a Mellonair extended probe, and I noticed that it does make the tendency of some round nosed pellets to tip over worse than with a standard probe. Exact RS seem to be the worst for that - they are very nose heavy. If I get the chance, I'm going to try a through flow probe as i'm guessing they push the pellet more evenly. My end-game is a full length sleeve with a through-flow bolt made out of 3/16 brass rod - should be fun :)

Nope did nothing to the bold just measured the peace of tape that was needed used another spare bolt probe to shape the curve of the tape so it would just slide underneath the bolt and that was it works great, hardest part was getting it to slide underneath without sticking to the bottom, i just used a pair of tweezers worked perfect i was actually surprised it worked so well, I'm very happy with this cheap and easy mod. :D

Take a guess what the extended bolt prob was made from :D
