OK now I'll come clean, I sent Keith a PM after my previous post saying I didn't really know what it was I was just stirring the pot to promote the mystery of it. Although I did have an idea because I know how Keith did the cradle for Altair, it's his style. -
Some really nice work there mate If you're waiting for a heat gun to use on the heatshrink there are other ways to shrink it. A hair dryer works well as does a cigarette lighter, just keep a bit of distance between the lighter and the job. It doesn't take a lot of heat but you want to spread it around the tube so it shrinks evenly

It's obvious what he's doing, I'm surprised you can't see it. I won't spoil his fun though!

Mark, the windlass on Waratah has gypsies for the anchor chain and similar brakes though the axis is on the horizontal, the brake is manually adjusted as the anchor is lowered so yes someone has to stand there and effect a controlled descent of the anchor
-
John, the SHF shipyard is closed for the duration, no cruises either because it is run by volunteers and most are in the senior age group most at risk
-
I'd follow a loco thread Michael As for covid, the Sydney Heritage Fleet shipyard has been closed down and all cruises cancelled because most of the volunteers are of an age deemed susceptible

Keith, further to Druxeys comment, there is an old wood turning trick whereby you glue the quadrants together with paper in between then after turning it a sharp knife can be used to separate the pieces. Clearly you loose half the thickness of the paper from each face but that would not be noticeable in most cases.

Love the oars Geert, I wouldn't have minded if you copied the leathering, that's what the site is about. Learning from each other, getting ideas from each other etc. Having said that, I do like the darkened rope on your oars.

Yeah Keith, I'm replacing the broken drills with 10 packs. The HSS ones Eberhard mentioned would be great but I haven't found any and these are cheap. As for work holding I still have patience to learn in that area, I'll always try the quick easy way first but I can generally tell when I need to go the long route before I start something.
-
Yeah Eberhard I considered making something better to hold the pins but I only needed 6 and have about 500 to work with. I'll have to keep my eyes open for better HSS drills but these are cheap and plentiful

I got a set of micro drills last week and they've been very handy despite the steep learning curve using such fine drills in a machine, I broke the 0.3mm while getting the 0.4mm out! I cross drilled three of the 0.8mm pins with the 0.4mm bit before it snapped on the way out after drilling the hole, I think a bit of swarf came up with the drill and jammed it. I had to drill the remaining three holes with the 0.5mm bit which required very accurate centering leaving only 0.15mm either side of the hole. I couldn't hold the pins in a collet because I haven't got one small enough so I just clamped them in the machine vice and then used the 1mm bit to start the hole to prevent the smaller drill running off the side of the pin and breaking. The wire I used to put through the pin is 0.3mm diameter The pins were cut just past the holes
-
Eberhard, you have a conundrum! Michael and Joe, thanks. Yes you become very aware of the slight changes in the breeze direction and strength as well as the tide and I still have so much to learn.
-
It's tough when the wife has different ideas to you, you know most sail boats have engines too.
-
Eberhard what can I say, change your retirement plans.

Richard, if you have the time and space, do it. It was a joy to build and every time I take it out I get someone wanting to know all about it, it never fails to attract attention.
-
It's beautiful Richard although when rowing, which I do more than sailing, she's light and easily influenced by wind. She weighs about 230Kg with me in it and there's a lot of freeboard. The centreboard helps in that instance but it can still be hard work keeping it on line but I'm doing for exercise as much as pleasure so that's ok. I haven't done much sailing yet but when I do sail her she glides along beautifully and will make way in extremely light breezes. I'm yet to encounter stronger wind and don't intend to until I'm a better sailor. I don't know if this link will work because it's from facebook, it was taken by a bloke I sailed with last year, mine is obviously the other boat.
-
Beautifully executed Keith, sort of the inverse of my method, giving a stronger result. I'll remember that! Is this why you were looking for an octagonal collet block?
-
Standing rigging done. I couldn't make the thimbles any smaller so I filed them down as much as possible to reduce the outside dimensions to suit the stainless steel wire which is smaller than the rest of the rigging, thereby making them look smaller than the ones in the running rigging. The crimps were made from the same copper tube that I used for the thimbles. Running rigging in place but nothing to tie off to yet. Still deciding whether or not to make sails for it.
-
Ah thank you, now I know what to search for.
-
Mark, when I built the full size version I went for classical craftsman type finish and that meant this sort of detail, not to mention the fact it protects the keel etc very well.
-
Thanks gents The rubbing strips are done and the model is once again righted. As a footnote on the construction of the strips, I secured the split brass to the MDF flat side down with masking tape to drill the pin holes to 0.9mm and then countersunk each hole to 1.2mm to allow the pin head, once reduced in size by filing in the pin vice, to countersink. Because the pin head reduction was done by hand and eye I had to remove some of them and further reduce the heads to fit in, a bid fiddly but I got there. I'm going to have to find a suitable collet to hold these little pins so I can shape the head properly in the lathe if I do this sort of thing again.
