Needs to drill 3" hole through ext wall.

[chickenwing]

it's brick and block. any ideas.. I don't have a drill that big, my goodness!

[Paul Franklin]

Rent a diamond hole saw and a big drill to power it at your local tool rental place. It will be well worth the $20. You'll probably need an extension as well, to get all the way through.

Alternative is to drill a ring of 1/4 inch or so holes with a hammer drill and a long masonry bit and then chisel out the waste. It will take a lot longer and will give you a rough sided hole, but will get the job done.

HTH,

It's ok, take your time. Now I do have a 10 GA Turkey gun, I wonder if that would get it started

[chickenwing]

I'll have option A there, for $20 Yeah I agree, man, when you got the right tools, it makes you feel smart

Draw the circle on the brick with a Sharpie. Then drill holes with a small masonry bit (3/16", 1/4", whatever) all the way around the line. Knock the piece free.

Single Jack and a cold chisel.

[neverhirelocalmen]

What is the jack for

[Sacramento Dave]

the Jack refers to the weight of the hammer Single Jack and Double Jack Can't remember what weight the double Jack kicks in Might be LBS. and up

[BobK207]

Single Jack Hammer: A single jack (3- to 4-pound head with short handle) hammer can be used with a star drill to punch holes in rock. The single jack can also be used to drive bridge spikes, and other uses that are too demanding for a regular claw-hammer, but do not require the heavy duty blows of a sledge.

I beleive a single jack was called that because it was used with a single hand, a double jack required two hands...........why they're called "jacks" I don't know

Dependin on how uniform & cleanly drilled the hole needs to be........

you could rent a Bosch or Hilti rotary hammer and a 3" core bit

cheers Bob
