boring bar bit removal

Is there something that unscrews on the other end of the bar? Or maybe where the "business end" joins the body of the bar in the region at which the diameter appears to decrease in your photo #2. I have a couple similar older bars that unscrew there. It looks a little rusty, so give it a good soak in penetrating oil. And remember that the geometry of the thing is such that the leverage of the tool tightens the screw when it is in use.

I've got one just like this. The thing on the end is a screw with a slot through it. The sleeve is supposed to turn freely on the bar. If it is rusted on, you've got a problem. That is a simple part, though, and might be easily made if you have to destroy the original. The screw should simply unscrew, standard right-hand threads and all. But, the sleeve needs to turn to allow the screw and bit to turn with it.

There is a special wrench for that type of bar. It will fit the slots in the end of the sleeve.

oops. well, that was embarrassingly easy. i don't want to use up my "please help me" coupons here. apologies for asking a question i should've been able to figure out on my own, thanks very much to Jerry, Bugs, Jon and John, 'specially Brian Lawson who sent me an exploded view pic. i posted Brian's pic to show anyone who may have been wondering the same thing as me but was too shy to ask :-) .

last night i gave it a good spraying w/ pb blaster and thanks to Brian this morning i confidently took it apart. i was kinda thinking probably the whole thing simply unscrewed but there was still a doubt if maybe it had a left or right hand thread (guess it should've been obvious though to someone who thought about it, it would be designed to tighten with use.) (but then again, that "bolt" part is surprisingly thin where the bit goes through it, maybe possible to break it clean off (?) if exerting a lot of torque on the "slotted" end exclusively, i mean, if there was a lot of rust/etc. on the threads.) (sure helps to be able to ask though. thanks!) (oh, and was able to sharpen and extend the bit and proceed with my small project to completion today, yay! thanks!) (pics tomorrow.)

b.w.
