very old cup and cone BB / crank removal...thin walled 15mm socket needed?

[pygmypony]

hey all, my wife has this sweet 1990s-ish LL Bean bike that is still very much in good shape...there's a minor bit of play in the bottom bracket / crank spindle that i'd like to get rid of...

in order to remove the crank arm to service the BB, i need a 15mm socket that has a super thin wall, i think...

has anyone else come across this issue and found anything that works, short of grinding down the outer wall of a 15mm socket?

thanks!

Have not come across this issue, but if it is 15mm, that's a pretty common auto wheel socket size and there are thin walled options available.

You want a peanut butter wrench. Look it up

thanks, i have the crank extractor, i just don't have the 15mm socket to remove the bolt...it looks like what @Karate Monkey linked to is exactly what i need to get the bolt off! i'm on the lookout!

Your extractor won't fit the 15mm? Can you grind the outside of the socket.

yes that's the next option, grind it down...was looking for an "anti grind" option...

 

[Dingo]

grinding is good

you got a friend with a lathe? thats probably the route i would go, just measure the ID of the recess and take a couple thousandths off for clearance, if i had a lathe id offer to turn it down for ya. that keeps the center of the oustide and the center of the hex on axis with each other.

@pygmypony The "Herse" one is the one you want. The other is strictly for axle nuts (it's a flat box wrench). I seriously doubt you'll find a PB wrench for sale at a bike shop, as 15mm bolts haven't been used extensively for years. Even Campy gave them up.

Like @Dingo said, you can get thinwall sockets that fit, too. Auto parts stores might have them in stock.

thanks all, went to the depot, bought a $40 ryobi grinder, and it’s done and it worked!

now i just need a spanner wrench to remove the BB!

 

[pygmypony]

also to note, i didn’t even have to grind the entire outer diameter to get it to fit...just about half of it...

So just the tip?

 

[Dingo]

Always good to have any excuse to buy tools

Okay, that one was kind of funny.

well too late, but put the socket on a drill and grind it against the curb?
i'll give you $10 for the grinder
