Fit­ting mid­dle panels

Practical Boat Owner - - Practical -

The mid­dle panels were much eas­ier, with only a small amount of curve to take up. These fit against the keel, into a re­cess formed by the edge of a piece of ply­wood. This needed trim­ming back to ac­cept the panel, and the per­fect tool for the job was a Bosch os­cil­lat­ing cut­ter, placed on a piece of scrap ply­wood, to trim the edge back enough that the bottom panel could fit un­der­neath. A ¼in chisel and mal­let made short work of any­thing left be­hind.

This done, we saw that we needed to plane a curve, and marked this by push­ing the sheet up to the keel and mea­sur­ing 15mm in from the edge, later join­ing these lines with a long, flex­i­ble bat­ten and plan­ing to shape. There­after, we marked the po­si­tion of the stringers and drove in tem­po­rary screws to hold it in po­si­tion.

The out­side edge over­hangs the chine panel at this stage – but this could be planed back to form the new lower edge of the chine panel once the epoxy had set.

A sharp 1⁄4in chisel knocked out any waste and lumps from the re­cess...
