Hi folks,

I'm trying to make a special drill for drilling out the stump of a 9"
sq wooden gate post but want to leave the surrounding concrete intact.



Have you thought about sharpening the end of a piece of threaded rod ? The rod comes
in all sizes and sharpening the end into a point and cutting a couple of straight
slots for few inches up the length would give you a cutting point that could be
drilled in and pulled out a few inches at a time.

Hmm, that's a new idea, like a very long starter 'tap' ;-)
I do have various lengths / diameters of 'studding' in the workshop
.... ;-) I'm not sure how well it would 'clear' though but I can see
the idea (I was probably going to have Henry working in there as well)
might work. I would imagine this would be very good for breaking up
nearly rotten timber but if this one is like the last one I did it
will be clean solid timber about 1" under the rotten end?

I think I saw some on the Screwfix website that is 1mtr long X M10 and was 94p a
length. B&Q also stock it at roughly the same price or not much more.

As you say .. pretty cheap experiment in any case ..?

All the best ..
