I just started putting T-Pins three on each side to hold the elev. in place while you measure, it works great just put the T-Pins right beside fuse and into elev. get it close by eye put the pins in and if you need to move it pull the pins from that side and slide it or whatever way you need then put pins right back and it wll hold it in place. Pull it out and put your epoxy if using that and then slide it back in put your pins back in the holes you made and very little adjusting is needed. If not epoxy you can turn it on itside and put your CA without it slipping while you glue it. I have a straight edge I use and mark on both sides when i get it set and then you just use it on both sides when doing your final epoxing or ca. However you measure the pins hold it in place great.
