Could I use this hook http://www.jannsnetcraft.com/oshaughnessy-jig-hooks/810131.aspx

with this mold http://www.jannsnetcraft.com/do-it-screwloc-jig-molds/412168.aspx ???

It doesn't look like it will work due to the angle of the eye of the hook. Click on the jig mold link and you'll see the recommended hooks have a 90 degree hook eye. Also, the hook eye you want is oriented differently and won't fit the mold.

MHO of course

you will have to modify the mold and the hook. Bend the hook back to a 90 degree bend and take a small drill and drill the hook eye slots to accept the flat eye instead of the conventional one.

if you bend the hook you will probably break it. You shouldnt need to alter the hook anyway. Lay the hook in the mold and see where you need to dremel to make the hook fit. Dremel a little at a time and keep checking. Dont try and do it in one pass becase you will ugly up the mold if your a little off. Even then its not a big deal, just more for you to trim off
