How to connect black stove pipe to Cl A Chimney?

Here is my problem: running black stove pipe up to cl A chimney ping through ceiling which pes through roof to outside air. I have 8" pipe, chimney and collar coming off stove. I am trying to connect a non-flared end of an 8" black stove pipe to a non-crimped 8" Cl A Chimney, or in other words, trying slide a piece over another except both pieces are exactly the same size. Any ideas? Is there some sort of an adapter out there that I can use and still be safe? Next issue: when it comes to the collar on the stove itself, the collar is where the damper is located and the crimped end of the black stove pipe must go in as well....First of all, the black stove pipe would keep the damper from turning, secondly, it won't fit anyway! I am guessing they make a "splicer" that I could use for this. Any help would be greatly appreciated. Also, this is a free-standing wood stove. Thanks in advance!
