Lots of good tips here, especially Rich's method of pre-installing machine screws into the conduit. Just one thing I haven't seen mentioned is regarding pull strings. No need to worry about putting them in place first, as long as you have easy access to one end. Put the vac over the end of the conduit, then tie a small piece of plastic bag to the end of your string and suck it through. We used to use this method successfully for pulling strings through up to 100m of conduit, where a fish tape won't help you. And if you the conduit gets flooded with debris, a septic pumper truck will provide ample suction to get it clear... (only had to try that trick once, but it was better than digging it up!).
Now I have a few options for when I finally get around to doing this. On a related note, my discovery of a nice hidden 4" channel between the water tanks and stbd settee inner liner face seems like a perfect place for conduit, and maybe even a forward heat duct for the Espar. It pays to poke around with a mirror while cleaning the bilge... :) -- Shawn Wright shawngwri...@gmail.com S/V Callisto, 1974 C&C 35 https://www.facebook.com/SVCallisto On Fri, Apr 10, 2020 at 10:40 AM Doug Mountjoy via CnC-List < cnc-list@cnc-list.com> wrote: > Nathan, > When I installed an additional conduit in my mast.
