Patent attributes
A laser marking device includes a fixture for temporarily attaching the device in an initial cutout of a number of serial cutouts to be fabricated in adjacent assembled I-joists. Combined with the fixture is an angle gage that provides angular positioning of a marking laser. The angle gage is configured to hold the laser with its beam coinciding with the marking origin of the initial cutout, which in case of circular cutout may be the reference center at which the pilot drill of the hole saw is centered at the begin of the cutout operation. The marker laser may be horizontally and/or vertically oriented together with an eventual alignment laser and an eventual target marker temporarily affixed on the I-joist where a final reference point is determined for an axial orientation of the cutouts across the I-joists.
