hi richard,
you did a 16" lightbridge one for me and mate yes i use it all the time..it is a bloody fantastic job you done for me... easy readable and extremely accurate..
i have it on my desktop in pdf so if anybody needs one it's there....
one thing i did do different was not use a paper then laminate but used a drafting film which will last longer and more durable then laminate-recommended from the place where printed and laminated..
i also reduced it to i think 99-98 percent of what you did just to come in on the base 2-3 mm and avoid any damage to the setting circle...
mate once again thank you..
