To re-in force the step, should I do this to only the bottom of the mast tube? So reach through the inspection port and sand down the old fiberglass and then lay more down where the tube meets the bottom of the hull, to make it stronger that way?
I ran a couple strips of cloth down from around the mast tube, spreading them out at the bottom, out onto the inside of the hull bottom. I think I did a layer of 4 strips at 90* intervals, then another layer of 4 more offset by 45* on top of the first, and then a 3rd layer of 4 offset by another 45*. So 12 strips in 3 layers. The strips were like 3-4 inches wide by maybe 12 inches long.
Then I ran a longer piece around the mast tube on top of those strips, to kind of hold everything together.
Sorry, I can see how that word "around" would lead you off the track, not the best ... picture's prolly better - here's the way I did it -Hi cskudder,
By "around", do you mean in a circular way while descending... like the coloring on a candy cane?
1st layer of 4 was "N - E - S - W" if you get what I'm saying - 90* between each strip.
2nd layer of 4 more was "NE - SE - SW - NW" -- 45* offset from 1st layer.
3rd layer of 4 was back to N-E-S-W -- 45* offset from 2nd layer.
Then a last strip like a belt around the mast tube, over these 3 layers of "descending" strips.
I simply wanted more material holding the bottom of the mast tube to the bottom of the boat - bearing that shearing force. I wasn't so much interested in covering up the original mast tube, or going UP the mast tube, cuz the tube part of mine looked real strong still and I don't think the middle part of the tube bears a great deal of force.Ok, got it. With the idea of the 3rd layer of 4, back to the N-E-S-W position, being simply to cover up any remaining strips of the original mast tube that haven't been covered yet by your new glass and resin?
The "belt" strip- I wrapped this one straight around the mast tube- just like a belt straight around, not like a barber pole. It was only 3-4 inches wide, not the full height of the tube. I put it only around the bottom part of the tube. It didn't cover the whole length of the mast tube, it just covered the lower part just over the part where the up-down strips reached up the tube. The goal with this one was to get some real strength around the OUTSIDE, around the CIRCUMFERENCE, of all those up-down strips. I was thinking if the bond between the up/down strips and the mast started to fail, I wanted this "belt" to have another layer of strength resisting the shearing, resisting if those up-down strips started separating from the tube. I think I put it around like 2 or 3 times.Do you mean a strip that wraps in a circular, descending pattern around the mast tube from top to bottom? Like a barber pole or candy cane?
Or do you mean a belt of glass that is as wide as the mast tube is tall that wraps, say, one and a half times around the mast tube?
haha it was the first thing I could lay my hands on. No, the 2nd- the 1st was a bottle of bourbon that was too big around for me to hold the bandana with 1 hand and take the pic with the other. The vermouth bottle worked. Put 'em together = a Manhattan, which is one of my favorite ways to keep warm this time of year.Nice job on the bandana and bottle of soda by the way. ;>)
a syphon of sorts, a giant syringe ... using this forms part of the putting her to bed ritual, the boat not the wife.
it's six layers of that cloth that's in the background, west epoxied, clamped cured flat, trimmed
