Has anyone had any experience or tips on filling in a punch mark in a set brass cap?
Scenario recently where stamping and punching a Monument that was set in concrete sidewalk. Crew Set up and staked out to the point, punched the brass cap. And then realizing that the wrong prism was set in in the instrument, which in our case is approx .07' (happens all the time just not while setting monuments). So now staked out to the actual point and punched the Brass cap in the correct location with the right prism. Crew used & symbol to make it less of a punch and then used lead to fill in the first punch that was incorrectly set.
Just wondered if anyone had any other experience in this.
Grind the incorrect punch mark off? Or am I mis-understanding the question?
I would probably incorporate the incorrect punch mark into a pattern of punches refferencing the center punch or "X".
I can only speak in a speculative manner however as I have never incorrectly marked a point.;-)
A grinder is best, but I've used a plain punch to fill in an errant dimple. This is much easier to accomplish in aluminum than in brass or bronze, though.

Well, if the brass tablet is large enough that a miss of 0.07 ft. still hits on the cap, you probably have enough space to stamp "JUST FOR PRACTICE" by the misfire and "REAL DEAL" by the second.

But if space is tight, probably "NFG" and "AOK" would work just as well.
STOP IT! You've got me laughing and folks around here are giving me strange looks....:-P
I had one boss that would take a chisel and make some gawd awful looking cut to take out a punch mark, then place a new punch mark where his best measurement fell.
:-O

Mission accomplished! :>
get another instrument and crew to stake the point. You will have three punch marks. Now you look like a normal surveyor.
ww co pls

LOL!!!

Punch it in, punch it out.
I'd try a 3/8" pin punch and just tap away around the edge of the original punch. All the material is still there... just persuade it to go back to where it was. When done, you might see a small dish type mark but the orginal punch will be gone. I just did it on an aluminum cap... the sharpie marks are pictorial reference only or maybe thats where the correct punch should be?! 🙂
Warning! A new or real nice pin punch has sharp edges. Round those edges very slightly on a grinder or you will end up with a lot of round edge marks. And then tap the surface to smooth it.. I use a 3 pound machinist hammer. Tap... don't hammer!
Before....
Punch mark made...
Punch mark gone...
Yeah, you could randomly put about 15 more marks on it and stamp a date about 20 years ago.
After its ALL punchy you don't need to punch it any more just pick the one close enough to where you would punch it if there were only a couple other errant punches.
Punch it in, punch it out.
Just add about 5 more punch marks.... let that guy with silver hair, write a book about it!!!
He he he
Punch it in, punch it out.
:good:
I just add my punch mark to your brass cap, so don't worry to much about it.;-)
Punch it in, punch it out.
HAHA! All truly great ideas i would have went with leaving both punches and stamping my bosses cell phone number into it LOL
What's a punch mark?
Is that made by one of those dimple machines?
could you make it into a crows foot incorporating the erroneous mark?
Dtp
I use a P.K. as a punch in a new disk. Why add a punch to the tool pelt.
Tapping will "sort of" remove the the incorrect punch mark.
