    Boom Bale Hole Repair

    I left it 24 hours, but it's pretty cool outside and I did notice that it was leaving deposits on the paper. Anyway, now that the weekend's over it will have to wait for Saturday, so it will get a full 7 days of cure before I hit it with the grit next time. Maybe I can sand, blow some more over...

    Boom Bale Hole Repair

    This TotalBoat primer is hard as nails. I sprayed on 3 coats - not exactly "orange peel", more like "ploughed field", but hey-ho, I'll sand a bunch of it off anyway. Bad idea - it's really, really hard. I started with 380 grit wet, nope. Moved to some 220, nope. 160 wet is also hard going, but I...

    Yeah - that's one of my best memories - winning our class at the 3BF and sending the 6 year old up at the awards wearing an adult small shirt with the hem trailing along the floor. I'm pretty sure that when he said "clockwise" to the "which direction" question, he let slip that the only reason...

    I think I broke them for sailing when we did the Farrallons a couple of years ago. We came in second, but it was "sporty" enough to need a reef on the way out (first time ever reefing the boat, quite an adventure), and I hurled over the back of the boat, which impressed them quite a bit. I think...

    I'm struggling with the spray pattern for the Total Boat primer. It says "thin up to 20%" - so I did that and it's pretty runny, but the spray gun seems to be failing to atomize the paint. I have to turn the flow right down to a small patch, which is more or less circular rather than a fan. I've...

    Round rope does not have the "coolness" factor of a strop. Also, climbing slings come in pretty colors...

    Something like this -  But that still has the problem of how to secure it from sliding... I have seen others screw right through the strop, but that's kinda ghetto. Ideas?

    I'm going to try using a climbing sling. Someone else mentioned that climbing hardware does not have the longevity needed for sailing, but they are so cheap. Worth a try IMHO. Bluewater ropes does some beefy spectra slings with high breaking strain. My main problem now is figuring out how to...

    Yeah - we can get Acetone. Paint is TotalBoat 2- or -1 pack primer. They say it's not for Aluminum, but I already sprayed Zinc Chromate on it, so the paint won't see any Aluminum, only Zinc Chromate.

    Boom looking very spiffy in its yellow ochre zinc primer. I'm planning to spray some regular grey primer over the top to fill scratches and imperfections. The paint says "thin with Xylene", which I can't get in the People's Republic of California. What to use instead?

    Yeah - pressing the "easy-button" would be to screw a small padeye to the top of the boom. Neater and nicer would be to screw a padeye into the track so that it's mostly hidden. I have seen another solution where a piece of dyneema is threaded through the boom - trapped on the top by a small...

    What's the purpose of the amsteel loop tied between the two strops at the shackles?

    Scuffed up the outside, scuffed up the inside (Dremel taped to a stick, with flappy wheel). Epoxy 1/16th G10 sheet to the inside. Fill with epoxy loaded with filler on the outside. Waiting for it to properly harden - will sand and see what I have tomorrow.

    Not going back to bails. I was thinking about the strength needed in the boom and the strength of the strop. It looks like a 22,000 N strop would be fine considering 800lb is about 3500N - so plenty of over-design. I wonder whether the strop can generate the same force as bails into the mast -...

    The boom is probably not under a lot of load at this point - the mainsheet has a 4:1 on the coarse tune and 6:1 on the fine. In a blow, I need both arms to pull the main in the last little bit, and I can probably row 160 lbs in a one off. So let's say 200 lbs max on the sheet, which means 800...

    Yeah - I'm starting to think that the filler idea is better than welding. Lower chance of a fuckup. Here's the plan: 1. Take some FR4 PCB material (or thin G10), cut a little oversize and put a screw in the middle 2. Scrub up the damaged boom around the hole so it's nice and clean with fresh...

    Yes. 30 years of salt and pressure and the stainless bolt holding the bail has drawn itself through the alloy. Hall don't make this section any more so I prefer to repair this one rather than get a new boom - it's otherwise in pretty good shape, just needs repainting. Trying to decide whether to...

     I'm mulling on how to fix this. Options: 1. Some kind of composite/glass/bondo bodge-up, then use a strop around the boom for my main sheet. 2. Aluminum backing plate. Weld around the edges and then either fill with weld - use bales again for mainsheet, or fill with bondo and use a strop...
