> I bought a 25000 lb anchor at a Government Liquidation auction a while
back.
> I thought at first it was Navy but a) the color is wrong, b) it doesn't

> A friend (who was very persuasive) claims it's an Army "dead head" used on
> (for example) a Ranger training course to counterbalance an suspended
> cableway or something similar.
>
> I want to use it for a similar purpose (couterbalance) but I can't get the
> top off. The anchor is made of steel filled with cast iron with a
> hemispherical bottom and a 6' tall 10" diameter post sticking up. In the
top
> of the post there's a 2 piece funnel shaped *aluminum* clamshell with 6
> recessed allen headed bolts in a circle around the edge of the clamshell
> top. There's a 1-3/8" hole at the bottom of the "funnel" and wire rope
marks
> on the tapered sides, so it seems clear that the clamshell is supposed to
> come out and apart so that a wire rope with a knob on the end can be
> inserted.

> I got the bolts out and the funny thing is that the bolt heads are resting

from

is

are

the
