HI Dave ,
hows the narrow boat coming on..?.. to get you srated on swordsman start by tracing all the bulkheads and all the parts to cut out , if you follow build to the plan you should have no problems,
make sure you keep evry thing straight and in line , use a board with a datum line down the middle,
put centre line on every bulkhead and part that has to line up build model uside down on board make sure the keel is straight , make tempory block jig and use set square to check every thing
both ways i use the plastic one the kids use at school, from pound shops ,
on my latest swordsman i have used 1/16 ply skins from stern to balsa bow less jionts and will take a better paint finish …….hope get you on the way . will post a couple of buid pictures and a
scetch of my build jigs …….Larry…….
