NICArcher : thx for the compliment my partner ( in the picture ) will love to know that her slippers are appreciated

Dengue : you pointed out the exact issu i m confronting. I m doing the floating tendons out of 18x30 ( mm ) then round it over BUT, my round over bit doesn't do the same curve as the straight bit used for the mortises so always end up with gaps on the diagonals of the tenon. Any suggestions ?

thx guys it encouraging
