I've been putting this off, 'cause I've never done anything quite this drastic to my mast before. But like most things I've done on the boat (fixing the transom, building a new rudder) it was much harder in the anticipation than in the doing.
It helped that for once I had all the tools and supplies that I needed to finish without having to run off to West Marine or Coast-to-Coast for something or other.
Putting on the new cheek blocks was remarkably straight-forward. After finding and marking the location for the new blocks I drilled the holes with my cheap yet long-lasting 1/4-inch Black and Decker drill I bought 'lo these many years ago down in California. Then I used my brand new pop rivet gun to fasten the cheek blocks to the mast with stainless steel rivets. Took about an hour, most of the time getting set up and getting tools out, etc.
After dinner I went back out and installed the J-mount for my new 10-inch windex. I bought this in the middle of last summer, but never got a chance to attach it, what with the limited amount of sailing I did (so I didn't miss it) and with my pre-occupation with building a new rudder.
I also attached my new jib block to the forestay hounds. That takes care of the top of the mast for this year. It'll be fun to try them out.
