PB-9 Plumb Bob

Who in their right mind is going to take a $100+ plumb bob to the job site when they can bring a perfectly serviceable $10 one? If you showed up on the job site with the PB-9 plumb bob from Bridge City Tool Works, you’d either get laughed off the lot, or all work would stop while everyone came over to admire this beautiful tool.

Precisely turned on a CNC lathe from solid brass, the 9.3 oz plummet features a removable stainless steel tip. If you remove the knob from the top of the plummet, you can screw it onto the tip to make a smaller 1 oz plummet. You suspend the plummet from a 21′, black-braided, polyester fiber cord that winds onto a knurled brass spool.

For storing and displaying the plummet, Bridge City Tool Works created a Juara wood stand which also stores the spool and cord. The spool cap/plummet stand also serves as a sighting target.

Available starting March 1st, the PB-9 plumb bob is on sale for $120 until March 3rd. It’ll normally retail for $130.

    I made an earlier comment about fishing lures – some catching more fisherman than fish.
    This looks like one of those cases where the tool may be designed more for the tool collector than for the professional user.

    I’ll stick to my General Plumb Bobs for Transit Tripod and general use and my Tajimas for door jambs. As a relative comparison this is about 3 times the cost of the Tajima and 10 times the cost of the General Tools – with no more funtionality.

    At least when you move up from a Transit to an Engieering Station – you get lots more for the price jump.

    Who would want to use a hundred dollar plumb bob when you could use a thousand dollar laser???

    Come on folks, that thing isn’t even mercury filled. With that cross section it won’t take much of a breeze to get it moving, and we all know how useful a moving plumb bob is

  4. Fred says:

    The issue is not the $100 – but that it does not buy you any greater accuracy.

    If you need an Engineering Station – then spending $ 3000 even for a moderately-featured model will:

    Re: Mercury filled – good idea but probably illegal in California

    Perhaps someone can explain something to me while on the topic of plumbs. Why are they made of brass? I’ve got a cheap stainless steel one that works fine and was cheaper then the brass ones. Best explanation that I have heard had to do with the steel reacting to magnetic fields more then the brass would, however, this plumb bob with a stainless tip would seem to eliminate that advantage.

    So the question is, why are good plumbs brass?

  7. Blind says:

    Course, I could have answered my own question had I double checked to make sure that brass was denser than steel. Oh well. Nevermind.

    This only makes me feel better about getting the cheap one at Sears for about 5 cents when they had that coupon.
