How many of us will be tempted to try to make 135 degree dovetails now that Bill has presented us with the problem and his solution? Many kudos to Bill and Derek and others who give us their problem to get ideas to help solve them. I follow these threads in great detail and while I'm no longer making any big furniture pieces I'm out in the shop every day and now I'm going to make some 135 dovetails just to prove to myself that I can. I'm busy making carved boxes a la Peter Follansbee for grandkids and greats and have made 4 sided dovetailed boxes but the 135 will be a challenge. You never stop needing to learn.
