The Morton Portable Glass Shop (PG01B) is a system of plug-in fixtures for Morton surfaces that transform them of them into a glass jig system. With this system and its accessories, you can make all the geometric shapes quickly and accurately; diamonds and trapezoids are no harder than a square. The Morton surface itself is sold separately.
We have been using the Morton System here at Whittemore-Durgin for umpteen years and can attest to its efficacy and durability.
