Re: mac 1-40 and 250 bar sizes

Another option is to adapt a Stihl mount bar such as the size to fit from say 038 to 066 .Stihl bars have a wide enough heel to cover the area around where the oil comes out .It just takes some work with a die grinder to enlarge the bar tightener hole.Maybe a tad on the oil hole .FWIW I have a 36" bar from an 066 I can use on both a 2100S Homelite plus a 125 Mac .With the Mac though I have to run a 7 tooth .404 instead of an 8 Tooth .Slight difference between the way both saws use their bar tightener . You'll need to make some bar spacers also .It's like snug fit ID for 3/8" to whatever OD  the bar slot size is ,12MM maybe ? Besides all that if you can't find a true Mac bar Stihl bars are easy to come by .
