Hi,

Last Sunday was a good day: I picked up two parcels containing many airgun related goodies from the USA.

These two Taiyo Juki Bobcats needed to be resealed. Normally I would send the valves to Lawrie aka "The King of Seals", but these turned out to be very easy.
The stems screw into the brass head, which is great. Terry Robb's QB78 valve seals fit like a glove, and seal well. Then I used Crosman 160 seals from Ped's kit. The probe o-rings came from my collection of old o-rings. I have only tested the .177, a big bang and three shots at 194, 195, 194 m/s; about 640 ft/s > 7.7 ft/lbs (8.44 gr JSB's). Must do a full shot string, it might be very steep. The tube holds 2 powerlets, of which only one is pierced; the tube cap does not have a piercer. The second is probably meant as a spare, for hunting situations? Japan only made airguns for competitions and hunting.
Very little is known about Taiyo Juki. They made a few models, of which the Bobcat, 380, Junior and Grand Slam are the most common. I think they were sold in the USA, New Zealand and Japan. There is also a Deluxe, which has a magazine. All work on CO2; I don't know why they didn't make pumpers, as those were very popular around that time (the seventies). I have read that Taiyo Juki's were made by the well-known firearms manufacturer Miroku. Miroku did not answer my email for more info (I didn't expect a reply, but ya never know!).

There is some info on the net. A BB Pelletier report

Great info on the Grant the Kiwis forum (New Zealand). Grant has two boxed Bobcats. Also info on Danny's forum of course.

These reseals were nice and easy. Now I need to do some testing.
The .22 (top) was very kindly given to me by a member on here from Virginia.
The .177 I found on Gunbroker, and a friend and fellow Titan fan in the USA helped me to get it. It was cheap. The action has a paint finish. I think it is not original. In fact many parts on this example are not original (open sights, screws, trigger spring). But that don't matter.



It is a Crosman 160 clone (yes, I wear awful slippers when tinkering):



This one had miles of trigger creep. I glued some leather on the trigger to reduce sears engagement. Much better now


These old seals become like a sort of tar


Valve stem disassembly. The valve return spring at the top left is not original. It should be longer. I fitted a few washers to make it work better.


Thank you "The Robber" (not everyone likes him lol!)


This German Haweka sight has great glass. The loading of the .177 pellets is a bit awkward with this low mount though.


Any fellow Taiyo Juki owners on here?
Cheers, Louis
