Impact Driving of Very Old Floor Nails

vendredi 30 janvier 2015

Good Morning Everyone



A friend has proposed a novel solution to a problem and I am wondering if anyone else has tried it. I do not wish to risk damaging very old floors.





Background



My house is over 130 years old with messmate floors (Eucalyptus Obliqua) and Tas blue gum floor joists (E Globulus). With over a century of drying the timbers are extremely hard - I cannot drive a nail into the joists and if I drill the joists the bit basically burns its way through.





The Problem



I want to sand and polish my family room floor. First I must drive some of the floor nails so that they are below the level of the sander, and then bog the holes.



When I did my kitchen I made a punch from tool steel and welded it to a bit of flat iron (to save fingers) and then used a short handled sledge hammer to punch the nails. It was very heavy going - five or six whacks on each nail!



And my family room is three times the size of the kitchen, and many more nails to be punched.





The Solution ???



A friend has proposed that I should use an impact driver on those recalcitrant nails, rather than a hammer and punch. Is this likely to work or am I likely to damage the floor?



These are fairly large hand made nails that have been well imbedded in the floor for 130+ years.



Has anyone any experience with this? Or is there a better option?









Thank you



Graeme
