Just started a Chester Yawl. Laying out chines in order starting with 'one' and aligning to a snapped chalk line on the construction table, the scarfs on neither plank aliigned properly. The bottom edge is together and the upper scarf edge is over a sixteenth (.063") off (gapped) as if the angle of the scarf to the 'chine' or plank is off. Went ahead and epoxied 'one' chines. Then in lining up 'two', they are off even more. The bottom edge - the 2 1/2" from the base line is closer than the top edge by about 3/32 (.093") this time. I went ahead and epoxied these 'two's' as well but if this is the way this is going to fit, it is going to look pretty bad where the scarfs are exposed on the inner hull when complete. I have checked my work against the plans and directions for assembly and I do not see a reason for this poor fit. This looks as if the scarfs were not aligned to the plank properly and if so, need to be fitted again making the chine too short by at least 3/16" (.188"). Too much of an error... The secondary reason for a scarf in plywood IMHO is a neat joint. This is far from neat! There will be a narrowing dark inner ply exposed on these planks.
What is the tolerance on these scarf angles? Looks like with proper set-up on the CNC machine, they would be very precise.... Maybe we are trying to output these kits in too much of a hurry?
Being very honist, we are not impressed with this kit at this point. This one will not look anything like the display model in the CLC showroom.
