Newb question: bottom bracket replacement

I have an 1960's schwinn bike frame that has a one piece crank and threadleas bottom
Bracket casing.

Without realizing, I bought a cartridge bottom bracket and three piece crankset to match the bB.

My question is, will it be possible to
Use the newer crankset and Bortom
Bracket in my old frame. The frame seems to be threadless where the bottom bracket would go.

Is it possible?

There is an adapter that converts Ashtabula (one piece) bottom brackets to standard English threads. Harris Cyclery has them for about $20. Look here:

Also, the length of bottom bracket axles varies depending on several factors. Hopefully you ordered a crankset that will be compatible with your frame and drivetrain.

Don't tell me what "should" be - either it is, it isn't, or do something about it.

If you think I'm being blunt take it as a compliment - if I thought you were too weak to handle the truth or a strong opinion I would not bother.

Please respect others by taking the time to post clearly so we can answer quickly. All lowercase and multiple typos makes for a hard read. Thanks!

But you'll have to replace the crank with a set of square-taper cranks, so it'll cost more than that.

Check the original post "I bought a cartridge bottom bracket and three piece crankset to match the bB."
Sounds like he already has those parts - assuming he's got the right length for the chain line to line up.
