The 120 mount was for dukes. Glad the skis are still serving you well!Remounted 2 pairs of DPS last night due to ever-shortening boots. No pics unfortunately as I was afraid of epoxying my phone.
I've used a modified version of Jondrum's template printed on semi transparent paper and re-used since it worked so well the first time.
The interesting frankenmount was the heel piece of the Lotus 120s which had been drilled once for Dukes (??, not my mount) and once for Dyna ST10s. I needed to move the binding about 2 cm forward and didn't have too many options so I ended up putting inserts in the plugged rear holes of the Dukes (same exact hole spacing, what are the chances). I measured everything 4 times to make sure that these holes were lined up and centered then re-drilled the holes to clear the epoxy. Enlarging the 4.1 mm holes with the 1/4" bit worked well and the hole seemed to be all wood (no epoxy sidewall). I was worried about the tapping part since I had only done it with a drill press but after practicing a bit on hard wood (oak for the chimney) I felt pretty good about mounting the tap on the drill and using the slowest possible speed for the skis. Three out of four holes came out perfect, the last had a couple of threads crumble when I went too deep. The inserts threaded in fine though with the expected amount of resistance. I'm horrible at drilling straight holes so one of the insert has a 10 degrees tilt. I used a 5/32" bit (3.97 mm) for the front 2 holes and used dynafit screws epoxied in place. I lined up everything with the boot in place and cranked the screws, no issues to speak of, alignment seemed perfect. I'd definitely want a drilling/tapping guide if I was putting holes in new skis though...
