I am doing a rather challenging project in an old home where the floors
were laid on a web of small joists supported on beams which are
basically complete trees with a flat side adzed along the length.
During the last 150 years, the lumber has copped an attitude of its own
and has become very creative in its non-levelness.
To attempt to correct this washboard/minigolf, I decided to snap a
chalk-line grid on the floor of 12" squares and that way measure the
elevation at each intersection relative to a level plane shot across the
floor with a laser. I transfer the elevation differences to the side of
2x4's and bandsaw them to fit the wobbles and valleys etc. I have used
this method in an office in Toronto before with great success, using my
dumpy level, and the end result was a very solid floor without too much
increase in height... now I want a decent laser. The client goes along
with the budget, Rob is happy, Rob gets a new toy, Rob gets to do a
Off I go to The Borg (Orange) and start checking claims on the displays
and I then check as much as I can on Google.... Back to HD...I want
something simple, self levelling, small, and something that puts the
beam as close to the floor as possible. I luck out on getting the help
of a very friendly lady who is not afraid to rip open packages of
batteries, so we can play with these things in the store.
Final bake-off happens between two lasers, exactly $100 apart. Both low
enough to the ground to make me happy.
The one with the thinnest line is going to be it.... we turn them both
on at the same time...and the Black & Decker BDL310S Crossfire wins it
hands-down over a Johnson Acculine Model 40-6620 for $ 100.00 more.
Goes to show ya...
