To layout dovetails;
1. Use the either dovetail square to layout a reference line. Next, adjust the sliding bevel arm to this line and lock in place. This will allow the user to use the dovetail leg first as reference to set the ‘T” Bevel for all the reference lines. This is mandatory if the dovetails are longer than the saddle square arm.
2. One can put a business card or other small uniform thickness between the body and the stock and scribe from heel to toe.
3. One can simply make a reference line and then realign the tool and continue the mark.
