Thanks everybody for the replies. I also think that notching the sear is not a good idea. only alternative is notching the pillar,but then it has very little foundation for the action to sit on.
here's my plan I will use a 3/4w x 1" L x 1" H block of 6061 aluminum. my stock (Tacti-Cool ) has a set back or notch to clear the sear that is .200 wide. the action screw's hole outside edge forward of the trigger inlet is at .450,so forward of this edge will be solid aluminum that the action will sit on once bedded with Devcon1010 even with the notch I should have a solid pillar. the front pillar will be 1"w x 1" L x 3/4" H and finished off with a traditional round pillar from the bottom. I did a similar pillar bedding for a H&R M-12 the rear action screw was offset also leaving vey lttile pillar foundation,but I didn't have to notch it.
If I remeber I will take some pics as I go along for those who might be interested on how it comes out.

Thanks
