I drilled the holes using the pin holes in the tang as the guide. The bit sizes are #30 and F. These are slightly oversize for the pins, but much less hassle trying to fit it all together at glue-up time.
I'll be using two 1/8" stainless pins and one sweet 1/4" mosaic pin for the centerpiece. I cut these with a hacksaw about 1/8" longer than needed.
I mixed up about 5ml of Acraglas and coated both sides of the tang, the insides of the bolsters and pin holes and squeezed it all together.
Normally I'd take off some excess with the bandsaw, but this wood is very hard and started to smoke right away. I opted to crack out the hacksaw to remove the bulk of the scales.
Of course this can be done on the individual scales before you glue up. It works either way, just seems faster to cut them both at the same time.
