Split forms

11/10/2019

The bow and stern pieces were planed to a knife like edge. This was achieved by first drilling small holes through the form as a guide to show where to plane to on the other side and then planing just shy of the 5/8 line.




The split forms were prepared by using a stanley knife to remove 15mm (the width of the forms) of the paper from the middle of the form.  This was done as a guide for the bandsaw.  The measurements marked on the paper were for 5/8'' or 3/4'' thick forms but mine are 15mm.



The delaminated section was then removed using the bandsaw and then the split forms were sanded ready for glueing to the end form.  The paper side forms were glued first and held with masking tape and then left overnight to dry before the other side was glued on.

The thin ply removed from the stongback in the triangular section was glued into the open angled ends and clamped, this will still need to be nailed in place.  I tried some plaster screws but they tend to split the hardwood ply when driven home (even when predrilled)  so nails are the go.
