This is a maiden from a Canadian Production Wheel and had been previously repaired. It was repaired with hide glue but the small bamboo skewer just wasn’t big enough to reinforce the joint.
I had to remove a nail holding the stub of the tenon on the end of the off-side maiden. Instead of making a new maiden, I decided to use a shouldered tenon and make it match the original. With the nail removed I could remove the stub tenon.
I cut the maiden off flush at the shoulder for the end of the maiden, then drilled a 1/4″ twist auger and then enlarged it with a 3/8″ duck bill spoon bit. I fit the new birch tenon into the hole, applied hide glue and clamped it together.
I also drilled a hole with a gimlet bit for the wedge and made a new one of birch to match the original
The next day I applied pigmented shellac to match the original finish on the parts exposed. The customer was happy.
