I wouldn't waste any more time. Get a power hacksaw and cut it apart
what would be the right tool to make a cut like that?I think cutting it would be the way to go.
Ayuh,..... I'd use my angle grinder, 'n a thin cuttin' disc,.....
Put the blade between the sink and fitting and slice through strainer. Use the longest metal blade you can findI wouldn't waste any more time. Get a power hacksaw and cut it apart
I am not sure.
A Hacksaw, with a fine tooth blade, to remove the bulk of the old drain, cutting as close as possible to the flat flange.
Congratulations. Persistence pays off.finally! went with a sawzall, vertical cuts to remove the center piece, then made cross cuts, pried the pieces away, and finally a fine toothed hacksaw straight through the center and split the threads in half, at which point the strainers fell out.
thanks for the help!
