Just a quick update on the Ray Iles O-1 plane irons I wrote about a few posts back. After clearing off and squaring up some rough cut oak 4x4 and 4x6 the iron in my #5 is still looking pretty good. I've used it both with the grain and traversing and after a good deal of use is still taking a nice shaving with the grain, so still acceptably sharp. I did inspect the edge while I had the plane apart for cleaning and it's ready for some sharpening but not too bad. I'm pretty pleased with the amount of work I was able to get done before having to sharpen. I could do more but I'll probably touch things up before my next planing session. Why push it?
Also the combination of new chip breaker, iron and opened mouth made things very nice. I had absolutely no problems with chips getting caught or jamming.
