There's several ways of adjusting the blade position. Lots of good info in the wiki: https://shavelibrary.com/w/Blade_Centering

I've also had good luck with what I think of as directional pinning. Post 13 has a good illustration of the concept: https://sharprazorpalace.com/worksho...tml#post905657

This works best when the pins are loose so you have more room for adjustment. If the pins are already tight you might not have enough play to get much movement. I check the centering frequently while peening as I slowly get the pins tightened. I also slightly enlarge my pin holes (5/64 bit for 1/16 rod) to give a little more wiggle room.
