I've been procrastinating putting on the triangle center spot for my farpoint cheshire. Taking the mirror out? Yikes! What if I break something!?!
Well I finally got around to it last night and ya know what? It's not scary. Six screws, lift the whole cell out, and set it gently on the floor/bench/whatever. Honestly the hardest part was finding a third hand to push down while I held the template in place.
Collimation with the cheshire is lovely easy. I sort of wish my arms were longer but it does great with few moving parts.
