Shaping
Hand saw - for cutting out outlines
Stanley Surform - for truing up outlines, taking down thickness, rail bands, foiling, bottom contours.
Sanding block - Wood block with foam on one side. Wrap your sandpaper around it, hard side for flats, foam side for curvier areas.
Electric Planer - Not a necessity for your first board but speeds up every aspect of shaping.
Block plane - For taking down stringer
Spoke shave - For taking down stringer in curvier areas the block plane can’t fit into.
Sandpaper - 40, 80, 150, 220
Calipers - For measuring thickness
Tape measure
These are the basics, you could shape a whole board with a surform and sanding block if you had to.
Glassing (poly blank)
Poly resin (use UV if you can, much easier for a beginner)
Catalyst (MEKP)
Surfacing Agent
4 and 6 oz. E glass.
Mixing buckets/sticks, squeegees, tape, chip brushes
Fin rope
Leash plug (looks like you’re set on that one)
GOOD RESPIRATOR
Sander/Polisher for sanding glassed board with various grits of sandpaper.
You’re also going to need some sort of racks and side lighting. You could go old school and just use sawhorses out in your yard.
Go with glass on fins for your first. Fin systems require kits, routers, jigs to install.
Check out Greenlight and Foam EZ they have board building kits with everything you need. I use Fiberglass Supply for most of my supplies. These are the basic tools you need but there are many more that you may want but add up to a significant investment.
