"what in the samhill is that?!?"

Glad you asked.

if you had said, "why, that's obviously a poor man's laser plummet!"
you'd have been quite correct.

We had set the monument boxes the last week in September, when I had enough manpower, to complete the operation, but didn't have my final positions for the two corners- these are the "magnetically detected" positions from a few weeks back. I knew I was good to a tenth so - as I said we set the boxes and drove on.

this week I went back down to set the mons- by myself- the crew is scattered to the 4 winds putting out fires-

i'd known ahead of time that it would be a pain to set and mark the monuments deep in the box- So I thought i'd prestamp everything I could then put the

DIMPLE

on after the thing was in and solid.

I thought a laser plummet would be sweet, because if you have a pole on the cap and try to mark it in the box it would be difficult.

I considered buying a laser plummet, but I had PO's my boss earlier in the week and didn't feel like begging for spending authority, plus it would be a pretty much one time use for me since I'm red/green color blind.

so I was driving down to Hamilton contemplating my slight predicament- and viola' (sp).

I stopped at the near by construction office and got 2 labels- and drew the grid on there- I used my motel key for a straight edge....

After prestamping the year and my PLS no. I went down town- not quite Willem Dafoe and Brad Johnson- but as enthusiastically as I figured the situation warranted-

I set up my Traffic control and mobed everything out to the intersection. I cut open the tops of the monboxes- we duct tape them shut when we are finishing the concrete to keep from sealing them shut. and looked inside- there was a divot in the subgrade from when we'd set the box and my measurement said it was within .05'

subgrade is 1.1 ft below the top lip of the box-

I put the breaker point on the thunderbolt and attempted to make a pilot hole-
and hit a stinkin' rock- I thought an unkind thought for a minute then broke thru the rock with the tool.

The caps are Berntsen 3.25" ac- we put them on a 3/4"X24" rebar, so I turned it over and drove the rebar into the cap then drove it down with a deadblow hammer, til it was out of reach then used a piece of 2x4 to finish driving.

I dumped in some chips and rodded them a bit to make it tight and keep things fairly free draining- then I whipped out my label- oriented it to north and stuck it on.

Then I set up a std tripod and tribach- positioned it over the corner- sited down at the grid- and using the ever-present dimple device, got 'er done.
