Oar leathers
I took an easier path and did not make my own oars, at least for now. I bought ready made, pine-loom oars of 3m length, just about right for my Ilur.
While mast and yard varnish is curing I sat down to put leather on looms. I chose not to install buttons - just long, heavy-duty leathers as I will use these oars also for sculling.
There are many resources on web showing how to measure and install leathers. I do it the way described in Wooden Boat article.
I made a die to punch holes. Pitch of 5mm was a bit of overkill, it would be enough with 10mm but… nothing too strong ever broke. It was just more work.
Wet leather, cut so that there is 6mm gap when wrapped around the loom, is held with rubber bands. The oar is aligned so that the seam will be on top when rowing, protecting it from tear on metal oarlocks.
I use curved needles, it’s easier than with straight ones. Strong, waxed twine. Stitch is called baseball stitch - nothing fancy but strong.
About one hour later the job was done.
After the leather dries and shrinks I will oil and wax it.
