I have a question about my hegner.I have had my saw for years but up until just recently I never had to use a blade like a # 1,# 2.Now I am trying portraits and have to use a smaller blade.My problem is I put the blade in the bottom holder, I used the 0.5mm clamp.Now when I go to thread it in the top I can't get the clamp to close on the blade.Maybe I'm just weird or my eyes are going.I have no problem with say a #5 or # 7.What am I doing wrong, it drove me crazy yesterday so I switched to a # 5 and had no problem.Just the blades breaking because of the tight turns.Could it be the quick clamp, just thought of that?Well any help will be great.....Dave
