Sea Knight - Cutting out the frames


By Osangar - Posted on 21 March 2012

Went out to the local wood yard for hardwood lumber to see what kind of wood I could find to make the frames of the boat.  The plans reccomend Oak, Mahogony or Spruce and my original intention was to use Oak but I couldn't get it in the widths I required so I ended up settling on Mahogony for the frames.  I might end up using the Oak for the keel, chines, sheers and battens though but we will see.

Since I cut out my gussets I couldn't resist just laying out one of the frame pieces just to get a bit of a sneak peak.  Still quite a ways away from actually putting them together, but whatever, need to get my little wins where I can. Frame Sneak Peak

All the pieces are cut out now that need to be done at this time.  Over the next while I will be planing and sanding these to clean up my poor cutting ability.  A bandsaw is recommended but I don't have the room for one so I am stuck using a jig saw.

I have started sanding and planing but this pretty much catches me up to where I am right now in my project.  With any luck I will be able to start thinking about assembling the frames at the end of the month.
