    Hello MIK,

    A little, thank you :). I'm hoping that I'll be up and about tomorrow, but I thought that of today - until I got up and found myself straight back in bed again! Still, hope springs eternal...and I've had at least two decent meals today, which is a lot better than yesterday!

    Thanks,
    the alex <twitch twitch, wobble wobble>

    I'm feeling a lot better today, and have been up and about for most of it - thank goodness! I spent a bit of today whittling away at the rear end-plate, so that it will look like a nice piece of furniture (see my avatar tagline for more details). There is actually a functional reason or two for the whittling, of course: removal of splintering edges; and very slight removal of weight, although the latter is fairly insignificant. Every little bit helps though, I dare say.

    I even took some snaps for you all:

    1. Front of the "duckcote" ;). The rounding-over and chamfering is finished here, and there remains a bit of tidying up via the Perma-Grit tools and sandpaper





    2. Port lower corner of front end-plate: still a small amount of scrabbling to do with the Perma-Grit tools and the sandpaper and the elbow grease





    3. Rear end-plate: more-or-less finished. I left the sanding dust whre it was in order to give the camera somthing to focus on - and also hopefully give an idea of the chamfer of the "new" sills. It certainly helped with the former, but not the latter so much





    4. Rear end-plate shaping viewed from the other side. The central sill will, of course, have the middle of it cut out for the upper gudgeon clearance, but I won't do that until the very last moment, as it's keeping the end-plate fairly rigid - and I don't want it flapping about





    5. An overview of the rear end-plate. In hindsight it would have been a lot easier to have done all the rounding over, etc., with the roof off...but I didn't, so it wasn't





    6. Another overview of the rear roof end-plate; same as before, really, only slightly less crooked ;)


    Follow this link to my Flickr account



    The four outer end-plate edges and the bottom edges of their "feet" will get rounded over next time I turn the roof over, whenever that might be. It won't be at the very least until I've finished off the ridge-cap and the rest of the top surface of the roof. Theodor popped over to look at the roof the other day (which day it was I can't actually remember as things have been rather blurry over the last few days), and was rather taken aback at its weight, AJ will be interested to know - although not particularly pleased, I suspect ;). Theodor did concede that there were indeed a large number of fairly large dead branches overhead, all awaiting their chance to smash the boat and her boatcote (ha ha) to pieces.

    I dare say that I could have got away with 6 mm ply if I'd added one or two more formers: the difference in weight might have been on the positive side (for lifting, that is). I still think that the compromise that I made was the right one, and in any case I'd run out of light former-making plywood! I may, of course, be changing my tune once the roof is "operational" - or not!

    While I was unwell I poked my beak above the ramparts and had a look at a few other threads: something that I don't normally do, in case I get driven to insane fits of jealousy over other people's nice work. I've said it before, but I can only see the faults in my work, not the good points (if any). Occasionally I see something that I've done that I think looks quite nice, but it gets overwhelmed by the catalogue of mistakes, bungles, etc. And it gets worse when I'm off-colour ;).

    Now that I'm feeling better - and I've done some more whittling away at it - I'm feeling a bit more positive about the 'Duckcote. More later.

    So it's going to be called 'Duckcote'? That's an appropriate name.

    Alex, you might also be pleased to know that I not only saw 3 wood ducks roaming freely near the kangaroo and wombat enclosures at Taronga Zoo on Friday (actually they were enjoying a pond at the time), but also dozens of wild bush turkeys. To be honest I don't understand why the rangers don't shoot and eat them cause they, the bush turkeys, are making a serious mess of the place.

    It was good to see you on Thursday arvo and see the progress on the boat's protective roof.

    Thank you for popping around: it was good to see you, too :). I'm wondering what the Botanic Gardens is going to do once the Terrible Turkeys reach that haven of MULCH. There will no doubt be A Great Squawking and Clucking - they're only just recovering (I think) from the flying foxes.


    1. "Glazing putty" - well, epoxy-and-sanding-filler filler - finishing off the front end-plate. The excess glue was cleaned up a bit later, when the resin had started to gel





    2. Close-up of new "glazing putty". Note the rough texture:this will be referred to later...





    3. More fillets. I've missed a spot in the lower edge





    4. Rear end-plate: a tiny bit tidier here: there was slightly less filler applied along the rear panel





    5. Close-up of rear fillet. The splinter jutting out from the bottom edge of the "foot" is one of the reasons for rounding over all the exposed edges. This edge and that at the front will receive the attention of the block plane in due course (before I separate the sides of the rear end-plate foot)





    6. Close-up of area around the gudgeon cutout on the rear end-plate. No attempt has been made to join or tidy up the fillet ends since that piece of the puzzle will be sugically removed wih a chainsaw when a number of other tasks have been completed - probably the last one before a resin-coat.





    7. What to do with the large amount of left-over filler? Use it as grain-filler, of course! There was a large area on this "B" or "C" side of the sheet which had a large number of grain voids, so I squashed the left-over filler into them with the side of the filleting stick acting as a squeegee. I should have been more attentive when selecting the side of the sheet to be pointing at the sky





    8. Lots of dead branches, all waiting to rain down on the boat - hence the heavy duty roof. One of these branches' former siblings was responsible for the hole in the foredeck





    9. The tree is a tallow-wood, I think (Eucalyptus microcorys, see this, for example). This snap gives a better view of the bark on the trunk. The tree on the right is a species of Genus Angophora; both trees are placed taxonomically in Family Myrtaceae

    Continuing on with the end-plate sill-filleting:

    1. Front end-plate after trimming the fillets





    2. Close-up of trimmed and smoothed end-plate fillet. In a comment in the previous post, I said that I was going to revisit the subject of the rough texture of the fillets. I left it a bit long and the gelling process had gone a bit far past what was really workable, hence the rough texture. I'll run a thin skim coat over these later





    3. Fillet on the other side of the centre-post, front end-plate. A bit wobbly - I didn't check the bottom edge carefully enough when applying the filler





    4. Rear end-plate again after trimming and an attempt at smoothing. I seem to be getting worse at fillets for some reason





    5. Fillet close-up





    6. Gudgeon cut-out with new fillets trimmed back a bit - to save my elbow!





    7. Close-up showing the unfortunately rough texture of the "water-shedding" fillet


    Follow this link to my Flickr account



    It's a pity I that had a rest after forming the fillets - and therefore just missed the period where the filler was at its best for working. I also made the mixture slightly too stiff in the first place, too. That means a bit more work to fix up, but hopefully won't take long. On a happier note, the Doctor Who episode tonight marked the return of the Ice Warriors - not seen since 1974. They didn't muck about with them too much - and there was a good script from Mark Gatiss.

    I'd better go and look into this skim coat before it gets too late.

    Good point ;). I don't want it to be me, either!

    I nipped down and did the skim coat immediately after tidying up my previous post. I used a very runny sanding filler+resin mixture:

    1. Preparing for the skim coat: masking tape. The fillet is still very slightly soft at this point. It's also still very difficult to see the slope on the top of the "sill", but it is there...





    2. Skim coat on: a very thin coat of filler+resin. This was very runny and a bit difficult to control. I'm also mostly expecting to find that the mixture has run right off the fillet and onto the tape by tomorrow morning!





    3. Close-up of skim coat on front end-plate. It looks a lot more even - let's hope it stays there!





    4. Rear end-plate skim coat





    5. Close-up of rear end-plate skim coat. If it runs right off I'll sort out the fillet texture with the undercoat - and some sanding


    Follow this link to my Flickr account



    One of the things that I did yesterday was push the sanding filler powder through a fine stainless steel sieve, twice. This worked well and dealt with all but the smallest (< 0.5 mm) lumps. The result when mixing with the BoteCote resin was much better than the last time I'd used the stuff. As can be seen in the photos above, both the filleting and skim coat mixtures are very smooth, apart form the uneven texture on the fillet surfaces, which was a function of the stiff mixture and not smoothing it off in time.

    If things go OK overnight and the skim coat doesn't flow off, I'll tidy the fillets up and sand off the roof panel that I squashed filler onto today. After that, a coat of resin over the whole roof, and once set, the thing will be turned over again and I'll do the final work on the end-plate feet and apply a coat or two of resin to their framing elements. I haven't made up much of the ground lsot over this last week, but I am at least moving ahead a bit more :).

    OK, change of tack - for the moment. The skimmed fillets looked fine this morning when I took the tape off. The lower tapes were a lot harder to remove on account of the large amount of filler on them, but at least there was still some skim coat on the upper parts of the fillets - so that's OK. A bit of sanding will sort that.

    I decided to polish off the roof - get the sanding filler off and some epoxy on. It's been a very long time since I've coated such a large area: I used a roller instead of a brush. I also remembered that I had a length of double-bias glass tape kicking about. and had the "bright idea" that it would complete the ridge cap. Compared with this stuff, the 50 mm tape that I used is almost non-existent! And of course weighs more and takes up more resin. AJ is going to have a fit...

    1. Second-last overview of uncoated roof: the filler has been sanded back by this stage. the "biscuit joiner" device on the Triton is there in readiness for a project for the family - once the roof is finished, or earlier if The Boss finally gets fed up! (I wouldn't blame her - I am already...)





    2. Double-bias tape





    3. Double-bias tape along the ridge of the roof - last overview of bare roof





    4. Roof - with one coat of Bote-Cote epoxy. The squiggle on the starboard roof edge is a trail of extra resin that poured out of the roller tray when I wasn't looking - and didn't notice until I was reviewing the snaps. The roller jacket hadn't been disposed of at that point so I hurriedly nipped down and mopped up and spread the trail quick-smart





    5. The other (coated) roof panel





    6. Roof panel slightly closer to...very eucalyptusy-looking. A bright finish is tempting...NO IT ISN'T!





    7. Roof panel again. There is some faint evidence of the sanding filler at this distance, although it is more apparent closer up





    8. Resin-wetted double-bias tape: it's very sticky, but I'm not 100 % convinced that it's saturated; it's quite possible that the sponge roller jacket has forced air into the glass along with the resin, rather than resin in and air out... At least it stayed put while I was wetting it, and didn't object to the roller being used on it





    9. Roof panel with extra resin "squiggle" flattened. It's still faintly visible as a lighter patch, on account of air bubbles from the foam roller sleeve


    Follow this link to my Flickr account



    All that - including the sanding - took quite a bit of effort. Once I'd dealt with the filler using 80-grit sandpaper, both panels then got a going-over with 120-grit paper. At least it looks a lot neater like that than before I put the resin on, as all the filler stains and previous epoxy along the ridge and around the edges have more or less blended in. I also used up quite a bit of resin: I'll decide whether another coat is warranted a bit later. It depends on how much soaks in; the double-bias tape will need another couple of coats (at least) in any case. That stuff is very hard to wet, and a metal compression roller might have been useful: except that I don't have one of those. Next up, either another epoxy coat on the roof, or fairing off the end-plate "sill" fillets (there's quite a ledge at the bottom of each fillet) - or both.

    Oh yes, and we're thinking of hiring a crane to move the roof down to where it will be used. Just slightly kidding...

    You have the luxury of sitting back and saying "I told you so" <grin>...should the thing be totally intractable . Looked at from another, more positive, point of view, it could be an opportunity for some more exercise...

    That's the superstructure, I take it? I guess if you can't sort something out, you could do her up and sell her. Then build a Bolger Micro or similar ;).

    Cheers,
    Alex.

    I got the second coat of epoxy (still Bote-Cote) on the roof this morning, after sanding both sides to knock the top off the raised grain. That is, sanding until the harsh hiss made by the 80-grit sandpaper softened to a quieter swish. After de-dusting with clean dry paper towels (changed frequently) I applied the second coat. So far, there has been NO sign at all of fisheye :).

    I'm also not recycling the (Duck Flat) foam roller sleeves this time, but chucking 'em when used once. I don't like doing that but it's one less variable in the fisheye equation. And so far, so good. That's probably it for the epoxy on the roof, apart from the heavy-duty double-bias tape, which looks as though it will take a couple more coats.

    1. Second coat of epoxy, starboard roof panel. Those screw-hole fillings really show up now (on this side at least)!





    2. Second coat of resin, port roof panel. The two joined pieces on this side are from the "A" or "B" sides of the respective sheets: no grain voids and only a couple of small top-veneer splits. Note the gouges in inner edge of the smaller piece where I slipped with the Perma-Grit block: while Perma-Grit is excellent for composite work, it is totally unforgiving if you slip up on wood





    3. Close-up of epoxy texture: some dimpling from the roller coat, but NO fisheye - anywhere at all :). Note the obvious staining form the filler: more noticeable here than on the "red" sheet on the other side of the ridge





    4. Close-up of the Jovian Red Spot; shortly to be covered in paint...


    Follow this link to my Flickr account



    Once that has gone off I'll get to work on the end-plate sill fillets - and another coat of epoxy on the new ridge tape.

    A couple more things to tick off the list: another coat of resin on the ridge tape, and the sill fillets' skim coats sanded :).

    1. Sanded sill fillet(s), front end-plate. It's actually the skim coat that has been sanded, not the fillet itself





    2. Close-up of sanded sill fillet





    3. Sanded sill fillets, rear end-plate





    4. Close-up of one of the rear end-plate sill fillets





    5. New double-bias ridge tape: this is the third coat of resin on this item - one more coat than on (most of) the roof panels at the moment





    6. Another view of the ridge tape. When the current resin coat has set I'll trim off the ends so that they can be finished off with the rest of the tape





    7. Yet another view of the ridge tape; snap taken without flash. The second epoxy coat on the roof panels has flattened out a little bit since I applied it with the sponge-roller five-or-so hours previously (and it has almost set at this point, too)


    Follow this link to my Flickr account



    I'm very pleased with the behaviour of the Bote-Cote at the moment: from this, it looks as through the fisheye problems that I was having a few years ago were a result of contaminated surfaces (amine blush(?), skin oils, silicone from tablesaw "treatment" and in fabric softener).

    Tomorrow, I'm either going to turn the roof structure over and finish off the end-plates (final shaping, epoxy), or put a couple more coats of resin on the ridge tape: probably the latter since the roof is that way up already. I'll prop the roof up before turning the roof over and give the floor a good hoovering.

    A quick clean of the floor with the vacuum cleaner while the roof was resting on its side was followed by manoeuvring it back down on its top surface, which took a bit of juggling. Once there, I started on the final shaping of the end-plates, beginning with the rear on, because it is harder to get at and psychologically easier to do first.

    1. Clearing the decks: I've even vacuumed the floor. There looks as though there is more space here than there really is: the camera is telling lies again





    2. Another snap of the interior of the "portable boatshed", a.k.a. 'Duckcote





    3. Back down on the floor, upside down





    4. The rear "foot" has finally been separated into two feet ;). You can also see that I've rounded over front and rear edges: I used the block plane to rough these out as it was quicker and neater - having unencumbered access to the whole length, i.e., no "legs" in the way. Shavings from this process can be seen in the background (and foreground)





    5. Gudgeon cutout viewed front-on. Look at that bench leg in the background - straight clear oregon! It and its three siblings have just been re-purposed ;). It's a pity that I ever cut it up, but at that stage I had no thought of building sailing boats...





    6. Gudgeon cutout with freed foot-end shaping started





    7. Port foot-end rounded using the Japanese saw to cut off the corner, and the coarse Perma-Grit files to shape the curve





    8. End-view of the excised foot section. The chamfer is obvious here - it is actually very slightly steeper than that on the front end-plate foot/sill, but the one on the front sill is still sufficient to not allow water to pool. The darker area on the top of the segment is where I brushed some left-over epoxy on last night, after sanding off the excess double-bias tape and putting another coat on the ridge tape before going to bed (and before cutting out the section today!). The saw-cut here is so clean that you can see the structure of the wood (at least in the original photo, it's a bit too small here). The meranti grain lifted quite markedly under the epoxy: it felt like one of the coarse Perma-Grit tools one the resin had set


    Follow this link to my Flickr account, where you can see my snaps at "full size"...



    Before I started on the gudgeon cutout, I rounded off the long edges of the still-intact foot and the vertical edges at each side at the rear: this leaves the the rest of the gudgeon cutout to finish off, plus the two verticals at the front and the rounding of the front foot long edges, before I start coating various items with epoxy again. I also acquired 300 x 1200 x 3 mm insertion rubber sheet today, for putting "shoes" on the "skids" and "boots" on the "feet".
