A block of mahogany 1m x 150mm x 150mm to replace the shaft log section of the sternpost will cost me .... $260! Yikes! So, looks like I'll be using PNG rosewood (one of my very favourite timbers) instead. I can get 75mm x 75mm rosewood so I'll just laminate that up, at about a third the price of the mahogany. The rosewood should be more durable, glues well and seems very stable so, hopefully will be suitable. Rick
Got the new shaft log in. It's a bit bigger than the old one to accommodate the different style of shaft bearing I'm going to use:

I also made up a jig for laminating new frames. I've put an old frame into the jig so you can see how it will (hopefully) work:

Progress is slow but it's nice to start adding rather than removing! Rick
I like the jig Rick.
I admit to having a few doubts about this project when you were telling me about it, but you're making good progress.
Making a new toerail myself, and that seems quite enough of a job to me!
That's clever, Rick.
How important do you think springback is? I mean, the ribs hold the planks in shape & the planks hold the ribs in shape.......
I'm sure springback is an issue but these laminated ribs will be fairly solid (about 40 x 40mm) so I'm not expecting too much. They'll all be bevelled to fit after lamination so hopefully there'll be enough leeway in the process for a good, tight fit. Rick
Well, I hope expectations weren't too high regarding progress on this project. Next week I have to return to Vietnam for a while - not sure how long this time but the Twister will have to wait a bit longer unattended. Sorry! Rick
No progress - just bumping! Happy to report though that the brattice cover has survived recent winds (seems to have been the windiest late winter in NSW for a long time) unscathed. Rick
What's the story Rick? Been a bit slack haven't you mate!!!!??
You could say that but it's just a bit tricky trying to work on a boat in Oz while living in Vietnam! I haven't been home since March. Rick
That's a long stint. When are you home next?Quote:

OK, back from Vietnam now and working in the Land of Oz, it's time to resurrect the Twister restoration and this thread. This summer's been really sunny and windy here in New South Wales - we've had floods up in Queensland and also down south in Victoria but here in the middle it's just been hot, dry and windy for the last couple of months. Great for sailing and we've been out on the Folkboat at just about every opportunity. But now, it's Twister time. First of all, we' had to level it up fore and aft so we used the ol' tube of water arrangement and that seems to have worked well. I used the old boot top as the reference so we'll just have to see later on how level that really is.

Then we levelled it up across the beam and improved the props.

So, framing's next. I intend to use PNG rosewood to make up the laminates for the frames. Hopefully the wood'll be here within a week or so.
Rick
Nice to see you back at it Rick. Do you want me to chase up that timber source up in Bris?
Welcome back!
Excellent. Say, where the heck has this thread been? Whatever, it is good to see Twister, getting attention.
This is a cool shot.
http://i470.photobucket.com/albums/r...k/IMG_4691.jpg
Thanks fellas! Yes Greg, if you have a good source for PNG rosewood or flooded gum up there, that would be great. I'm after dry boards suitable for planking, in 4 x 1 or wider (but they don't need to be wider), in lengths of about 4m (a bit shorter is okay, a bit longer is also good but I don't want to pay a premium for length.
I should mention that it's still going to be slow going on the Twister as I'm working full time again and I also have a house to paint! Anfd there are distractions - had a great sail yesterday!
Rick
No excuses Rick! We want pics of building work, no more skiving off with holidays to Tassie and sailing on the weekends!:DQuote:

Inspiring!
Rick
And for sale. I had a good look over her with a friend who was quite interested in her, she's lovely (but I think she's a bit small for him and his family).
Yep, great boat but if I really had my druthers I'd go for something about 34' I reckon. But, we have this one and I think for a couple it should be great and there's no doubt about their seaworthiness. Ours is heading for Tassie or the GBR or maybe even the Land of the Long White Cloud if I get brave enough, or maybe all three! How would you say the room inside Able Mabel compares to the H28 Greg? I'd say she'd be a bit roomier as she's a bit deeper and has a smaller cockpit. What did you think?
Rick
I was actually a bit surprised that she seemed so "pokey" inside, the H28s all seem more spacious in their various layouts. My friends have three very young children and the five of them would fit reasonably comfortably into a H28 but we looked at Able Mable with that comparison in mind and it just didn't seem to have enough space for them all. Though that may have been the layout and I didn't get any shots inside her to remind myself why she seemed so pokey.Quote:

Unfortunately I didn't take a whole of cabin shot. It didn't feel pokey to me but then, after a Folkboat, nothing else seems pokey!!
Rick
Sorry Rick, Pokey is probably the wrong word, I just found her that little bit smaller than I'd want for myself and too "cosey" for my friends family. But I think that forward bulkhead and narrow doorway doesn't help. I reckon you could do away with that, have a porta loo instead of a head and open up the bow to the cabin a bit more.
No apology required! I don't want our boat to be pokey so any of your ideas on how to make it less so are most welcome! Those bulkheads are under the mast step so they're needed for strength. However, I'm going to be putting in a series of ring frames (so to speak) in that area so I should be able to widen that entry to the forward berths I think. I probably will install a toilet though as we want this boat set up for cruising and I think Trace's tolerance for the bucket might be wearing a bit thin.
Rick
Rick, some quick comments. Laminated ribs are good, but messy to do. Could be better to laminate in situ, do every second rib. Fasten from outside with chipboard screws through existing rivet holes till glue sets. Predrill for screws, use pine blocks on inside as "nut". Drill correct size for copper nails, some WD40 sprayed in hole before nail being driven in helps. Minimum 5 laminations to minimise springback but there will be a little. Laminated ribs will be harder to spring into place if not perfect, some fairing may be needed. Back up any glued heavy section timbers with metal fasteners. That plank damage near fasteners looks like some electrolysis damage, possibly rusted steel/iron floors replaced with stainless floors. Would be concerned about boat strength in aft area, maybe laminate some "bridle" pieces across the top of the stern post to land on top of ribs, use longer nails through both and a couple of srews to attach to the sternpost. Re room inside, Ghost is probably similar to Twister, typically english, deep but not so wide. American boats seem to have more room due to greater beam. I do like the standing headroom in Ghost for the full cabin length, which I dont think a standard H28 has. A compression post will free up room forward, if cabin extends forward of mast.
Cheers for now
Adrian
Good luck with that restoration - a big job but you seem to have the energy and enthusiasm to carry it through.
I have a Twister - a 1967 composite boat built by Upham's of Brixham, Devon.
They are fine boats. I have had mine for 14 years and have no desire to change to any other boat.
Have you joined the Twister Class association, by the way? You would be very welcome.
http://www.twister.org.uk/index.html
Thanks Adrian. I quite like laminating though and I don't find it too messy. I'm going to use the jig I made up to form the new frames and then fair them in. I'm going to replace about half the frames - all frames from the mast back. The frames will be substantially thicker than the existing steamed frames and I'm going to fasten the planking with screws into the new frames rather than copper nails. There is a cabin forward of the mast, in fact there's quite a lot of room up there, so I don't want to use a compression post. I'll be setting up several ring frames (almost) near the mast so I'll just see whether I can reduce the restriction caused by the current bulkhead arrangement. I think the stern area is pretty strong so maybe it just looks a bit light in the photos. I'm sure you're right re the damage to planking and frames from those metal floors. They were installed to accommodate a water tank. This is the original design but I don't know whether the floors that were there were original or not. I'm not sure yet what I'll do about replacing them.
Twister, great to have you on this thread - I hope you'll be able to answer a few queries as I go with this! I have contacted the Twister Association and did get a response. I'll dig out the old emails and see what it was.
Rick
Well, I just picked up 45 metres of 100 x 38 PNG rosewood from a supplier in Sydney. I'm assured the stuff only comes from certified suppliers in PNG, which should mean that the timber mill supports sustainable logging and supports local landholders - I hope so! This should be enough to do most of the frames, if I don't mess too many up! So, I'll be looking for planking timber now - either PNG rosewood or flooded gum, I think. So, I just need to finish painting the front of our house and I'll then be able to spend a bit of time making up the new frames.
Rick
Brilliant!!! How did it compare price wise with up here and what sort of sizes can he do?Quote:

Sorry Rick, I thought I sent you the cubic meter price from the guy in Bris'?? He had 125mm x 36mm; 100mm x 36mm and 75mm x 25mm in 3metre lengths at $3500.00 per cubic metre.
Thanks Greg. I don't remember seeing that. Anyway, it was a bit dearer than that but not too much! I'm pretty convinced that they got it from a kosher source so I don't mind paying that bit extra.
Rick
Just bumping this up. I'm wrapped up in work and shed and house renovations at present so the Twister remains on hold. Lots of ideas developing though!

Rick
No progress to report except the wind ripped the cover to pieces so I'm about to put corrugated steel sheet up there instead! Just bumping this up for Euro.
Rick
You've had some wild weather down that way I believe.
A bit. You guys up there are lucky you live in a light wind area |:)
Rick
That's why I made my sail bigger than the 303 sq ft on the plans.:D
Bump for Sayla but some progress to report soon!!
Rick
