push nipples cast iron basaeboard

     I am reinstalling cast iron baseboard for a customer of mine that just finished renovating a house he bought.  He installed new windows throughout the house and sprayed closed cell polyurethane foam insulation on all exterior walls and also in the ceilings of all the rooms. The original baseboard lengths are now way oversized. 



     I am separating some of the sections of the radiators, but I am having a hard time removing the steel push nipples between the sections.



      I was wondering if any of you out there have a better way than me to remove them. I am currently heating the bushing with the torch and then I chip out pieces of the bushing with a small chisel and a hammer. I get them out but what a pain in the ^%$(^$)+. I know somebody out there must have a trick up their sleeve when it comes to this,



     Somebody please................................tell me how to pull a rabbit out of a hat!!!!!

    twist them with my Knipex 12" pliers

    That's all, if I have new ones to go in.

    Before you shorten them Lower the water temp.

    If the base board is over sized you can drop the water temp and leave them the current size. This will save even more on the fuel bill and even out the heat. This also means putting them all back to the original length.

    If you need to remove those push nips

    take a length of all-thread that's longer than the baseboard section and run two nuts on either end. One end should have some all-thread sticking out to beyond where the push nip would extend. Lock the nuts together. Then hammer on one end gently while using the projecting all-thread on the other end to keep the nuts on the inside of the nip.



    It worked for us.

    Stick a 1/2" x6" nipple in the push nipple and gently tap it up down and front to back it should fall out.
