Title: Another Kessler Resurrection
Post by: threesuns on January 10, 2022, 11:01:17 PM
Have had this 3rd variant, as a parts gun, 10+ years. the receiver where the stock screw attaches is stripped bad. Other issues … missing stock retention screw, pump cup missing & valve condition?? but cosmetically not too bad & 95% complete.

having brought my 1rst variant back to life I though 1 day I figure out a way to bring this 1 back too.

well its going to happen … a NOS receiver & stock screw showed up at my door today. 
 
Looking for suggestions to try to duplicate original crinkle finish on the receiver. my 1rst thought is spray on bedliner ??

One day I hope to find one to rebuild, until then I will be happy to see your progress on this one. As for finishes, I am in the same thought as you for using a truck bed liner type paint, but others may give a better option as some truck bed paint seems a little rougher than the original Krinkle finish.

Well if you want to get into building Kessler.

Mike,

I think that’s a little more than I want to take on at the moment, but it is tempting. All I am looking for is one to set next to my 1880’s vintage Kessler Brewing Company Beer Bottle, that was produced here in Helena, Montana.

Out of curiosity I lost track of them or maybe you sold them all, do you happen to have any of your Crosman 114s available? I really like the Crosman Model 99 I picked up from you last fall.

finally got the kessler apart. Should’ve been a combination of copper & leather shims to seal the valve halves but this one was glued together. looks like the hammer spring lost a coil or 2 at some point too.

Good news though ?? … the new stock screw is too long & will need to be cut to length and only the last 1/4 of receiver is stripped. the remaining 3/4 inch was packed with shavings on top of the set screw that holds the valve. maybe it can be saved.

Following. This is very interesting. Please be generous with photos of your build as you move along.

so here’s the valve assembly in order … input 1/2 of valve is soldered to compression tube, check valve is 3 pieces with seal sandwiched between 2 parts that unscrew (seal easily fab’d from a crosman end seal) valve spring, poppet ball, seal nut, seal (again easily fab’d from an end seal), valve body (my 1rst variant was brass), hammer, spring, nut, striker & pull knob.

again only thing missing is the copper & leather shim seals between the valve halves … which I will replace with an O-ring. A little trial & error to get the thickness right to align the exhaust port with adequate seal & compression while in the receiver.

Thank you for the organized picture. That’s an interesting design. That valve spring looks similar to the football style used in early Crosman’s 100, 101, 102’s. I like to know the dimensions too if it isn’t too much to ask. The spring wire size too. The reason being is if the Kessler used the same spring as a Crosman and Steve has some NOS springs in stock this could really help some of us with the early guns.

Also, that ball valve design is a great feature. What a classic air rifle.

Kessler valve spring. sorry for the pics … my digital calibers battery is dead & I haven’t used these ones since high school. Digital tech has made me forgot how to read.

here’s the check valve disassembled.

is it .053 or .052 wire ??

Timothy wife and I are almost out the door. I’ll get back on the wire and the check valve looks just like an early Crosman.

Can’t thank you enough.

is it .053 or .052 wire ??

I believe that wire is .053 or fifty three thousandths. The length looks to be around 1-1/8”.

I’ll add some dimensions of the spring from my Crosman on another thread so it won’t confuse any Kessler builders. Mine is different enough to leave it out.

Thanks again!

new valve seals installed … O-ring between valve halves … 3/16 drift punch will align TP, then valve set screw will lock it down & I will tighten the compression tube. O ring should compress, sealing the valve & atleast provide an addition seal between the valve and receiver, on 1 side, since there is no TP seal (if I have the size right).

i think I have it … maybe a degree or 2 off but since its only hand tight it can easily be tweaked later.

I tried using the copper/leather shim method when rebuilding my second variant model A & gave up. not sure how the factory did it. I didn’t want use goop & have issues getting it back apart when & if need. IMO O-ring is the way to go.

Thanks, Kieth

stock screw shortened, installed & holding strong. getting ready to install & adjust pump rod.

forgot … have an old picture of a kessler seal kit. since the pump cups R pretty unique … I chose to go with a Mac1 delrin O-ring pump for my Model A 2nd variant because I just love that 1 and shoot it often.
Title: Re: Another Kessler Resurrection
Post by: threesuns on January 14, 2022, 12:57:28 PM
Well it’s not a power house … in fact 10 pumps is only in the 550fps range. Quite a bit off from the advertised 700fps but then my other kessler is just barely over 600fps.

You won’t win any target competitions with it either … it was the last build before the end. Notable differences in build quality between my 2. but it’s a plinker again.

I’ve put 2 pumps in it & softly released the hammer, if it holds overnite, I’ll call it done.

Nice save, Kessler's and Rochester's are among my favorites. I have a standard Kessler that shoots RWS Superpoints in the 690 range with 10 pumps. I think part of the reason for lower velocities is reusing springs that were heated up when breaking old valve solder during resealing.

Well I’m happy it held air overnite. 
You might be right about springs Jon, but I didn’t use any heat during disassembly. 
My model A I blame on headspace. The Mac1 flattop just doesn’t fit the domed valve face like an original cup would but I’m glad I saved that for the model C.
And the model C I could probably adjust the pump rod another 1/8 turn top & bottom but they are so close to maxed out & still not bottoming out.

Timothy
Can you give me the serial numbers stamped on the pump lever of your new model C please.
I have been collecting Kessler serials trying to refine the timeline on when they were made.
The model C has two variants.

Thanks
Dave

Yup
I thought so a late Model C variant 2. Made toward the end of production!

Post by: threesuns on January 15, 2022, 07:23:53 PM
that must be why I see such a deference in build quality … 1 low serial number & 1 high number.

Both of these were my oldest pending projects. Glad they are done.

what’s next ???
