Today, the weather was calm (pretty unusual for Heggerscale), dry (very unusual for Heggerscale) and almost 8-degrees C (almost unheard of for January at 900ft), so it’s time to hoist the mast and cast the rubber foot for the mast to fit into the tabernacle…
It’s the second time we have hoisted the mast, but last time involved so much trepidation we forgot to take any pictures… So this time Louise (on light duties having tripped down the stairs yesterday) was pushed into being the team photographer.
The “running foreguy and bipod”, as recommended by PJR, can be seen doing it’s job. Once up we poured the casting rubber into a plastic bag surrounding the mast foot (to make sure it didn’t stick to the sides of the tabernacle).
The pictures tell the story:
The team assemble to plan to deed. Colin, Mike and Malcolm
Pulling the boat out of the barn – Colin and Malcolm were helping from the stern!
All rigged and ready to go.
A lift from the stern to get the lift started, and the foreguy (and Mike) take the strain.
50% of the way, Malcolm inside getting the foot set true.
Very nearly in place, with Colin on the safety line.
A close-up of the bipod and foreguy rigging…
The mast in place, temporary clamps on, ready for the rubber to be poured. – and the weather closing in!
The photographs make the bury of the mast look short, but it really is 10% of the mast as recommended. It also looks quite vertical (it should be according to the drawings and machining of the foot block… Now (once the rubber has set) we can drop it down, fit the masthead fittings and wiring, and then set about rigging the sail!
Time to make a Yacht!
Following on from appearing to have (temporarily at least) sorted the steam plant, it’s time to get on with fitting Befur with her Junk-Rig sails, so that she can truly be the Steam Yacht that she was always intended to be. The embarrassment of having to be towed home on three occasions also sharpened our desire to get this job done. Continue reading
Today confirmed the order for the mast for Befur. A 6.4metre extruded alloy lamp post!
This is an unstayed mast, to support 16sqM of sail. Spent a long time trying to figure out how strong it needed to be – then suddenly realised it was much simpler than trying to figure the maximum wind load on the sail (guessing at maximum wind speed we might encounter) and realised it only had to be able to capsize the boat!!!
So the answer was a 177mm diameter, 4mm thick lampost, that tapers down to 90mm at the head.
Also reached the point where we could compile a list of the 70-odd outstanding jobs to finish Befur and divide these into Jobs to be done in Hampshire and jobs to be done once we have relocated to Cumbria. While it’s a daunting list, at least it’s fairly complete.
As noted in the last post, the plans for the cabin/mast arrived from Selway Fisher. Having poured/poored/pawed?? over these for a few weeks we have concluded we are going to slightly modify the proposed arrangement by installing a set of steel bracing inside the boat to support the Mast Partners (the thing the mast hinges in when being trailered), so that we can reclaim a little more internal space. We understand this is another bitter pill for the wooden boat druids to swallow, but hey, this is the 21st Century! Continue reading
