Fiberglassing the Battery Tank
As you can see from the following images, the inner fiberglass shell has been made.
Battery tank, putty spacers.
Battery tank, temporary wood infills.
Battery tank, fiberglass mold.
For ventilation/expansion etc, the molding is spaced away from the metal tank by half an inch or so. This is done by cutting wood sections and placing on top of ‘play dough’ spacers. The fiberglassing is then applied to the floor, and then on the wooden wall fills using gelcoat, a little over half an inch thick (which is catalysed using a hardener). Time is needed for curing, before a skincoat is applied.
Once dry, the shell is lifted out (actually, it got stuck and needed a lot of force to budge) so the underlying dough spacers and wood fillers could be removed.
Since the batteries can generate heat, we’ll need to consider extraction fans or proper ventilation tubing; we could come up with a pseudo ‘exhaust pipe’ for venting heat perhaps.
