Almost winning the battle with the mighty Crosman 600

[@WalnutandSteel]

After attempting to repair the two 600’s I have they both wound up in the capable hands of Henry for repair. A man has to know his limitations!

Well documented 😂

[@PongbyAtari]

I have a nice works well 600 Boxed with manual. I had a friend who's well versed in the 600 get it working & resealed cycling well. Not something I shoot often but love owning this interesting piece of Crosman history. I commend you on tackling this one nice job.

I sent mine out to Precision Pellet to have it resealed . Never had a problem with it after that . I only shoot flat nose wadcutters in it . Seems to run very reliable . I had read once that these old repeaters run best with wadcutters . Works best in my Crosman 400 to . Which is pretty much the same mechanism but manual bolt action instead of semiautomatic .

I’m glad you had the patience needed to keep working on this gun so we could see it. Beautiful piece but too much bother for me to own

[@christopherfranklin972]

Very cool looking pistol and a great concept but Crosman clearly didn't believe in KISS. I admire your dexterity and patience!

[@canuckair]

I know. It's hard to look at this 1960 design and connect it to the 2240 type guns, that are just refinements of the old 150 type. Clearly, in 1960, saw a bright future in complex, highly engineered air guns. After the 451 (and maybe a decade of building the 600) that bright light dimmed considerably.

I had 1 in the late 70s and after Pilling to bits could not get back together finished up putting in the bin😂😂😂

[@stevedeline2537]

Ahhhh I've been waiting for this is one!!! Super fun

[@xelntchancechance2466]

Similar experience with my 600. Now relegated to be a display piece.

"Wonderfully complicated"

It has intresting finish glosy

The end seal variant of the model 600 was an absolute disaster for Crosman. It got so bad that warranty stations were ordered to completely convert all guns returned for service back to the original piercing cap format which meant tossing out the compression tube and all end seal parts. The one mistake I did spot with your final assembly is that you did not tighten the front half of the valve assembly after it was installed in the compression tube. That is what the large cutout slot on the front of that section is for. You install the complete valve with front and rear sections hand tight only. Once the valve is secured in place with the two pins, you tighten the valve front with a large blade screwdriver which expends the Oring in between the two sections to create a gas tight seal. As Nibs mentioned, when in doubt send any model 600 to Henry Ford although I suspect that may be an issue for you being in Canada with your gun laws on both firearms and airguns.

[@canuckair]

Actually, I really cranked the two parts of the valve back together, once I realized I had the wrong o-ring in that place. Off camera, I put the valve in my padded vice and used a straight edge to wind the two parts together. I'm not sure if it shows up in the footage, but you can see the valve with the o-ring showing after I hand tightened it. But after it's snugged down, there's no gap to be seen. My gun had a hard life before I got it, and I expect there's some wear and tear leading to some loose tolerances. Still, I expect Henry Ford could fix it up, but I agree that shipping a handgu-looking device over the border and back is a headache I don't want to consider. It's not necessarily the actual gun laws to blame, but the shipping companies, postal services, and border control agencies (on both sides) who are afraid of interpreting them. I knew a guy who got detained by customs for a couple of hours because he had an empty gun case in his truck. They actually called in the RCMP, who took one look at the empty case and shook their heads in disbelief.

Ok brother, this will be a stretch but think about doing a conversion back to the original system. you will need to source a used early (or late) production 600 compression tube. I've seen these listed before so keep an eye out for one. Likewise try H Ford, J&G Airguns, Precision Pellet, etc. as they might have something laying around. The other item you will need is the early model piercing cap assembly. Plenty of decent aftermarket versions available right now. This will at least resolve the leaking and will absolutely provide more performance as the earlier design was more potent than the end seal system. Good luck... - SRG - Classic American Airguns on FaceBook

RWS super h point cycle well in mine...

[@canuckair]

@@SteveGibbons-x7c One fly in the ointment is that Crosman put a threaded hole in the bottom of the compression tube. I understand that was to allow access to a stuck CO2 powerlet and lever it out of the gun. Converting back to the original piercing mechanism would require plugging that hole perfectly - welding it and then grinding it smooth inside and out. I think a much more sensible solution would be to just find a 600 that was working better.

[@SteveGibbons-x7c]

@@canuckairSorry I have not been able to get back to you sooner brother. Once again, the 600 story is a real mess. The End Seal revision was a major nightmare for Crosman, a number of rather ugly issues with the End Seal Block Assembly shooting out of the gun when the tube cap was removed while the gun was still under full pressure. (Insert Lawyers here....) The hole at the bottom of the frame was for a screw to secure the End Seal Block assembly from coming out of the gun. Yes, a CO2 cartridge (the original bottle cap type) could adhere itself to the End Seal (not unlike the early 1st variant Crosman 622 Rifle) and be pain to remove. The sum total of these problems would force Crosman to go back to the original tube cap piercing design which did save the gun from being discontinued altogether. Obviously enough, there are still End Seal Piercing guns out there so would-be collectors/shooters need to be aware of these issues. I did warn Nibs at Walnut & Steel about this when he was playing around with an End Seal gun some months ago.
