Re: Davit
Went to a scrap yard, found a piece of 1.5", 3/16"-wall stainless pipe with a minor bend where I didn't want it and no bend where I did. Went to a friend's shop, heated the pipe with a torch and slowly put in the bend I wanted. Being an advanced metal worker, I removed the extra bend with a high-tech device that we call "The Jeep." Yup, put the pipe on the driveway and drove back and forth over it until straightened out.
Used a 3" long pipe nip ple screwed into an electrician's floor flange for a deck mount.(Miss Prudence, the iFish censor, won't let me spell it properly, sorry!) I used a galvanized downspout strap for the upper mount.
I drilled the pipe tip, threaded in a stainless eyebolt and attached a Folbe open block which came with a swivel. After the first trip, I removed the swivel because every time we flipped a rope at it, the block swiveled away.
A friend has a similar rig and motor vibration backed the nut off the eyebolt, allowing the block and eyebolt to sink to the bottom of Yaquina Bay. To avoid a similar loss, I threaded the eyebolt thru one wall of the pipe, then thru a stainless nyloc nut, and then out the other wall of the pipe. If the outer stainless nyloc nut loosens, the inner nut should save me $40.
After the third trip and after the bleeding stopped, I drilled the pipe so I can slip in a pin to keep the davit from swiveling and rapping me in the head when I'm not paying attention - which is usually.
What would I do differently? I wouldn't use stainless. During this project I learned the term "work hardening". I would have saved a lot of money over a commercial davit if I hadn't burned through about $27 worth of drill bits installing 6 holes. I think this davit would hold a submarine if it got in our trap. (The boat will flip before this davit fails, which is not a plus. Given the options of making a new davit or testing my PFD again, I'll go with the davit project.)
My primary crabbing partner, the long-suffering Carl, and I are around 60. We do not have a power puller and haul our gear by hand. The davit changes the angle of pull and our lower backs are better for it.
