Thanks guys. The splices are just simple v-splices about 4 inches long. The Ash is edge grained cut to the shallow curve. One bow was deliberately left thick in the splice area so just wrapping will be sufficient to reinforce it. The other had recurved tips cut off it, so the splice is a bit thin. I'll add an underlay to that to reinforce the area.
There is nothing really different about this style of bow, it's just an alternate method of achieving static tips and getting that classic horsebow look.
It's also a bit easier to achieve stable tips this way.
