Thanks again for all the replies guys.
spc I understand your concerns. The Elm stave I did was a very large stave. I first removed Bark with draw knife. I then took Cambium off as carefully as I could with draw knife. I did very slightly violate, scrap,scuff whatever a person wants to call it in about a dozen places. I really wish I would have thought of this first but I didn't. It literally took less than two minutes to power wash this stave perfectly clean with zero violations of any kind that I'm aware of, other than the ones I did with draw knife. The mess was way less than washing my pickup after driving our muddy gravel roads. I'm sure many people don't have high pressure washer with burner and others that wouldn't do this even if they did and I totally understand and respect that. When I first started harvesting HHB I didn't know the difference between winter and summer harvest. I had seen on you tube somewhere that you where suppose to harvest in winter so that's what I did. I have made several bows from these staves leaving some cambium on and knicking ring in places. I even used one of them for hunting this year and haven't had a problem with any of them. Anyone who uses summer harvested HHB soon realizes that this wood has many dips, bumps, ravines and ripples that make removing cambium a real challenge. I also like a perfectly clean back for laying out my bows. I like to follow the grain, it may not be totally necessary but I like the wiggles anyway. When I did the Elm I was concerned about powder post beetle holes and wanted a clean back before I continued. It was really out of nothing to lose that I tried this. Having said all this I'm not totally 100 percent sure I'm not doing something completely invisible to my eyes to this wood that could possibly effect it in a negative way. I was however with my draw knife. In all honesty I expected to get a lot of negative feedback that this isn't primitive and I understand that. It's not meant for those bowyers I respect their view point. This is for the ones who are sharing the same problems I am. I also would advise anyone trying this that so far it looks fantastic, but I haven't made a bow from one of these staves and possibly there could be a negative I haven't yet noticed. Thanks again for all replies + or -
