SCRIBE TRY SQUARE
Though layout may not determine the quality & expedition of your project, it may very well facilitate it. Moreover, should you compromise here; you will definitely not forget the consequences. One crummy, poorly laid out stick can cost you an afternoon. A hole in the wrong place, a one inch error, a cut on the wrong side of a squiggly line, or a mortise where it does not belong, can & will spoil your flight plan. An understanding of metrology* and a dependable layout square will increase your odds of success.
I designed my tool for me first; I use it. I use it for direct measurement, scribing and knifing lines, some easy setup and checking for square. All of its edges have been machined and ground; they're straight to +or- .0005"/beam length. The tee is square in 4 places to at least .001". It can be used in either hand on either side of the stock. Moreover, it can be used upside down or backwards. You can scribe a line from zero at the reference (right) end of the stick to within 1/4" of the opposite end, using the same reference end as the starting point.
The tool works well on metal, wood or plastic. The tee configuration provides the ergonomics for easy handling and a reference for the supplied 10.00" straight edge. You can pull the beam against the edge of your sample and press it down with just one hand, stabilizing it. The reach with the straight edge in play is 9.50". The straight edge is shouldered to aid in its registration to the square. The 5.750" cross beam can be retrued** in the event of wear or a drop to the concrete. A lot of application, a fun tool to use; it could save you time & money.
1. Product includes the Scribe-Square & the 10.000" ground straight edge, (both Aluminum). The blade of the square has been precisely notched to lock & nest over the beam. The stainless steel screw holds them together. It is not adjustable.
2. The straight edge is shouldered to register to the blade of the square. The finger/thumb hole provides a means for the beam to enjoy some intimacy with the straight edge. So, with one hand you can square and hold the components firmly together.
3. Another view of No. 2. In this case I'm using a pencil; a knife is also an option. The straight edge is in contact with >4" of the beam. That and the interlock of the shoulder with the blade, provide adequate purchase to keep the straight edge from slip/sliding under duress. Note the blade against the stock, doubling the contact of an ordinary square with the work.
4. If measurements and scribe lines are to be made, measure directly from the reference edge/end to the square.
5. I designed the tool so I could always measure from one end of the work. The beam, with 7.75" of possible edge contact, allows markings to within a 1/4" of the opposite end without losing a grip on the tool.
