So I’ve got some rusty old floor screws that I can’t loosen with a Phillips head (they’re old, so I’m betting it’s not posidrv). The notches are all rusted and it hardly bites at all.
If I drill them out, I know I’m in for a hard time but am I better off going for a really fast rotation or slower?
And should I start with a narrow drill bit and work my way up (historically I’ve broken a few doing this in the past) or just begin at the intended diameter?
Yes, in fact I do work with computers - isn’t it obvious?
Just wondering, do you need to save the floor board?
No, I don’t… It’s plywood that has been under damp vinyl for far too long (there’s bound to be some significant work to remediate the floor)
We’ve had many of these. We just leaver up the boards and tear them out.
You could plunge cut with a circular saw along the edge. Then work a chisel under it and just tear out the floor boards any way you can.
Then for the screws, I either tear them out with pincer pliers for the shallow ones (you can get decent leverage with pincer pliers). Or just cut them flush with the joists and leave them there (quick work with an angle grinder and cut-off disc).
PS. Sorry been trying to reply to you for a few hours but my client wouldn’t connect.
