I'm remodeling my bathroom, and just finished demolition. My toilet was not mounted on a flange, rather it was screwed directly into the subfloor with drywall screws (no wonder it always rocked!). The house was built in the mid 60s, and te drain pipe appears to be made from lead with an integrated flange. This flange is clearly not for mounting the toilet, but seems to be there solely to support the wax ring. I don't think there are any issues with the drain pipe, but I'm wondering how to create a better connection for the toilet. Do I need to call a plumber? Or is this a DIY thing?

You only get ONE CHANCE to make a mistake, otherwise you will be removing the whole lead bend and replacing it. A plumber would revise the lead flange, install a brass flange, solder the two pieces together, secure the flange, then reset the toilet, properly.

Depending on the damage to the plywood, you may also need to replace the plywood. Toilets need really strong backing to secure it and prevent rocking. You will need a water proof cover such as tile or linoleum to protect the sub floor and facilitate cleaning your finish flooring.

Now, what plumber would recommend using an all plastic flange, and lead being malleable might eventually expand from the pressure and the flange would come loose.

an all lead flange is A-OK
yours is actually at the proper height to accommodate 3/4-1" of finished flooring
the issue is securing the bowl to the subfloor
i would use 5/16" stainless steel 'coach screws' which are wood threads on one end and machine threads on the other
if tiling:
install screws after backer board (through same) before tiling
install screws using a plastic flange laid on top of the lead as a template (the plastic will NOT be used with the toilet)

he was asking for a DYI solution. anyway, i would think the rubber ribs on that flange would make up for a millimeter of expansion.

EVERYONE wants a "diy solution" even guys doing plumbing for a whole house, but not everything works with one.

packy,
he simply wanted to DIY properly, so he asked plumbers for advice
based upon his 'surgical' finished floor removal WITHOUT damage to a lead flange i gave it
my answer was based on what I would do for myself if I had purchased the house and found a lead flange in good condition
peace,
john
