Claims: I claim:

1. An assembly tool for use in connecting fiberglass handles to tool heads, said assembly tool comprising means for holding a tool head with a piece of masking tape extending across the top of said tool head in overlying relationship to the handle receiving opening of said tool head, a tape applicator movable with respect to said tool head, said applicator having a concave resilient pad formed complementarily to the convex portion of said tool head surrounding said opening, said pad being constructed and arranged so that said pad upon movement thereof toward said tool head engages all of the peripheral edges of said tape adjacent to and surrounding said opening and moves said edges downwardly simultaneously while applying no pressure against the portion of said tape which extends across the top of said opening, whereby said tape is drawn tightly across the top of said opening, said padd being adapted upon further movement toward said tool head to press the portions of said tape disposed outwardly from said opening inwardly simultaneously into sealing engagement with said tool head around the entire periphery of said opening while said tape is held tightly drawn across said opening to seal said opening against leakage of potting compound inserted into said opening to bond a handle to said tool head.

2. The structure described in claim 1, said pad being formed of cast silicon rubber.

3. The structure described in claim 2, said rubber having a Shore A hardness in the range between 20 and 60.
