@james-fleming Oh yea, there were always exceptions ! but on average, most never got pinned. Carl always had the money clients. LOL
Carl always had the money clients. LOL
Carl's problem was always a failure to extract enough of that money to cover his costs.?ÿ
We have had good results with a rotary hammer drill. Also if the nail is a little bit loose in the hole the best thing that I have used to tighten it up is small pieces of?ÿ rebar tie wire stuffed down in the hole. We used to use the tie wire system with regular Framing nails to attach to concrete or sometimes even rocks.

I used to use the fluted masonry nails but ran into quality issues.?ÿ Now I use the 3/4" mag-nails with the plastic survey mark disks.?ÿ The disks make it easy to hold and drive the short nails without smashing fingers and mark the nails so that they're easy to see on the footings.?ÿ I used to get callbacks from contractors on a regular basis because rain and mud had obscured the nails and paint.?ÿ When the nails are driven flush the edges of the disks rise slightly and are easy to see even after a good amount of rain a mud.?ÿ They're also durable enough that shoveling the footings doesn't yank up the nails & disks.
We use a center punch on the end of the rod. Then set a magnail. If concrete is green pound it in. Else use a cordless hammer drill. We set nails on all floors if ten story hospital the day after every pour. I've thought about mounting the prism over a hilti 22cal nail gun.?ÿ
I have used tapcon masonry screws. Drill the required hole size with a hammer drill and set the screw. I have also used them for control in sidewalks. Use the required hole size full depth then use 1/32? bigger than the head to countersink the Phillips head also holds the rod tip from kicking out
The small rotary hammer drills with quick release head and tapcons set flush is the best for the mason, is efficient, and you never have to worry about a bloody thumb.
Set the tapcons flush if there's a chance the footers can get covered with debris and will need to be shoveled out.?ÿ The masons will love you because they can simply back the screw out a bit, hook their chalk string to the tapcons and snap a line.
I learned this by asking a mason what they do when they don't hire a surveyor.?ÿ?ÿ
I have received the smallest mag nail (3/4 inch), with the little square flag tabs.?ÿ I think they will be stout enough to just drive straight in, which is the fastest in my experience.?ÿ ?ÿMy son and I pinned the 48 corners in about 4 hours, with me dragging because of onset covid, and this was with many of the nails bending and requiring another nail(s).?ÿ ?ÿSince the mags are so short, I think I will try holding them with a wire stripper wrench rather than by hand, to get them started.?ÿ I don't pin many houses for construction anymore, but have one coming up.?ÿ I appreciate the advice,?ÿ Thanks.
