I'm posting this as a new topic but it could just as well have been added to AtlLaw's post on Gripmakers. My 1860 originally had the one piece walnut grips and I wanted to continue with that style rather than two panels connected by a cross screw. I therefore had to glue in the provided spacer. I decided to do it in two operations, first glueing one side to the spacer, trimming that panel and next day glueing on the other panel. That seemed easier than trying to keep three separate pieces all lined up togather.
These photos show the one side set up and ready to trim, showing how much there is to be removed. Removing that much material produces a flat which has to be blended in to the contour so all in all it requires quite a bit of material removal. I will post photos of the finished grips when they are done.
