I’m getting to where I can eyeball the widths pretty good and only need Calipers every once in awhile.
This Dowel was 5mm thick and I brought it down to 3mm. But I started 15mm from center. The middle bit is left thick.
I use an Xacto blade and File for the notching.
What I do is to first put Contact Cement on the Shroud and also the Futtock Stave, which is basically a cut down Toothpick.
Once make contact, I use my Tweezers to get to spacing right. The Contact Cement has just enough give so I can adjust it. Once I get the spacing right, it’s just a matter of squeezing the 2 sides together. After a hat I drop some Superglue on it to fix it in place.
I ended up using a double binding for the Catharpins. it’s a challenge doing this in an enclosed area, but I’ve tied so many Clove Hitches, that it’s second nature now.
