My first rolling nut crossbow build is progressing steadily. As I've not done this before I'm kind of making the design and solving the problems to fit with my repertoire of skills and tools as I go along. I will shortly have to decide whether I go for a bolt rest or a groove. This isn't a replica, just a bow based on the medieval style and technology so historical accuracy isn't an issue. I'm thinking that if I cut a rest from a scrap of ipe (very hard and oily wood which I will also use for wedges) and put this in a dovetail across my oak tiller it should be less work than cutting a groove and easier to get centred and straight with a bit of adjustment available for tuning.
Any thoughts on the advantages and disadvantages of the two styles?
