    I started with build of a-pillars
    rings were cut on CNC and then chamfered behind the driver cutout and also in front.










    T-nuts were added

    Terrter will be held by neo magnets - 4 pc for each tweet


    Before start, rings were soaked with poliester resin. This asure that bond with filler and MDF will be as strong as possible and wont crack where two materials meet.

    Original upholstery material was stripped down from pillars. Pillars were sanded, drilled a bunch of holes in and covered in three layers of rowing/mat and trimmed.



    taped off back side of pillar



    after fiberglass was applied

    back side of pillar will recieve additional layer of fiberglass to create a Sanwich of Fiberglass/ABS/Fiberglass


    a part of pillar at the bottom is without fiberglass applyed

    next stage in pillar fabrication was to create molds of the dash, which will serve as bottom part of the enclosure.
    Car was protected with alu tape and painters tape.....

    Next task was to mold together this bottom part and pillar







    A mix or resin and filler with strands were used to make milkshake which was used to "glue" this two parts together






    Large opening on the pillar was created to obtain enough unobstructed air-flow for midrange to vent under the dash. All original pillar fastening spots were preserved






    Rings positioned and secured in place
