Hi guys
I've been doing a lot of building surveys recently and it would be really helpful to mark points on external windows cills/sills. I'd then like to set a ground tripod like the one below over the point and measure it with a robot.
Where I live lots of the cill are either concrete or granite and unfortunately are often wet! I'm struggling to think of a way to mark a point like an "x" or an "o" on the cill. Anyone got an idea? I don't know of a pen that works in damp.
?ÿCheers, Andrew
Thanks party chief
The Milwaukee Inkzall marker is one of the best I've used.?ÿ Works pretty well on damp surfaces and the tip is very tough.?ÿ?ÿ

thanks for that, amazing review on a Amazon, will get some

Great ideas above.?ÿ Beats my idea by a factor of 100.?ÿ I was going to suggest a center punch and an 8-lb (3.64-kg) sledge hammer, ???? ???? ?????ÿ
Probably not a good idea.
@jim-frame what is it? If it is pencil how it will write in wet surfaces?
Rechargeable electric hammer drill with 1/4 and 5/8 inch diameter drill bits so you can set a MAG nail
it is a masonry/concrete scribe.
And it works fine for tight locations.?ÿ I carry one in my vest, but the tool I use much more often for scribing crosses in concrete is one of these:

I couldn't tell you how many hundreds of X's I've Scribed into concrete in my construction days. Almost every day. All it took was a plumb bob tip and the straight side of a hub... As apposed to the curved side???????? a couple distance calls in the field book to things around it and it's permanent.?ÿ
thanks again guys for the answers.
I normally have sds drill bits with me on site to help me encourage survey nails into concrete. I found that the tungsten tip of the sds bit is really great at scribing into concrete.

Me too.?ÿ Also used my bob to dig in hardpan and gravelly clay.?ÿ But doing so wears down the bob tip so it needs regular replacement.?ÿ Oh, also forgot playing "quickdraw" where you whip out yer bob from its holster by the string yoyo style at a target on a tree.
I'd be wary of scribing crosses on window sills, could be liable for damages by an irate tenant.?ÿ If necessary I'd scribe it subtly and rub the ejecta into the grooves so only a surveyor could recover it and a quick whisk would reveal the cross. Clearly the tungsten pen is the right tool for the job.?ÿ They're handy for shooting beer cans in one gulp too ????.
