I took the turret strip and power resistors and made my preliminary candohm replacement. I still have to cutoff the excess length, but the finished strip will be almost identical in length to the original candohm, which has at least two bad sections.
A few notes: I used 10 & 5 watt resistors per the recommendation of John Goller (K9UWA).
I decided to remove the unused turrets and found the easiest way was to use a 9/64 drill bit on the bottom and just lightly remove the small lip on the bottom of the turret.
To get two resistor leads to fit in the turret I had to gently enlarge them slightly with a 3/32 drill bit. There are ways around this but it would not be as neat. If you do this drill slowly and practice on a couple of the unused turrets because the first two I tried did not go well. As you can see I wound up with several extra turrets that I could glue back if needed, or if I found a similar piece of base material drill it and make a custom turret strip for a candohm replacement.
All-in-all I'm pleased with how it turned out and my connections to the candohm can just be wrapped around the applicable turret and soldered.
