Hi Neil , congratulations on your new to you W32 . I would make a templet out of cardboard , and make the cheeks out of teak . I get teak from buckwoodcraft .com

They have the best quality , selection and prices that I have found . And they don't have a minimum .

Good luck and keep us posted .

Hello Neil.  Just a couple of thoughts:   You can make the cheeks about 4” to 6” shorter without changing the appearance much.  This will help keep them out of the water when moving.   Also you could use the wood of your choice laminated to Divinycell foam to save more than 60% of the weight.  The cheeks were 3/4” thick.  You could easily make them out of 1/2” foam and 1/4” wood.  I chose oak for the appearance.  You must use epoxy for construction and keep them varnished.   The area around the 4 mounting bolts of the SS box must be solid, ie, no foam.  Saraband’s cheeks are more than 20 years old and still look perfect.  I sand them once a year snd apply 2 costs of spar varnish.  Sometimes 3 costs.  Good luck,   Dave
