Oz PDR build in Adelaide - sexy black PDRacer

m2c1Iw · #1 6th Apr 2008, 09:56 PM

or how to really complicate a great set of plans.

Hi thought I'd better post some pics of my progress as I did't make the Ubeat Squadron SA Division sail day. I was distracted all day thinking about you blokes bobing around at West Lakes.

So got my plans off Ted at Duck Flat at the end of January ordered some epoxied Gaboon and the fittings kit, really glad I did as the time saved and the finish they do is well worth it. I have decided to have a lug rig and as I have limited space and had to wait for the ply I started with the foils pic1. shows them with the tips glassed and ready for final coatings pic2. is the spars also waiting for a coating still need to do a bit more sanding round the top of the mast a drill the hole for the step. Next weekend maybe.

The ply arrived in time for some progress over Easter although many interuptions meant I only got the panels cut chine logs laminated and fitted pic3. shows my japanese style western saw.

Now to the complicating of Miks plans, he'll probably chuckle when he sees this and advise me that my total lack of consideration for stresses will result in disaster. Oh well for me the journey is as important as the destination. Anyway I was cutting out the pieces for the 2nd frame and trying to get the grain to line up, those of you who have built an Oz will know what I'm talking about but I found my measuring stick somehow had lost about 20mm. Oh no what to do no spare ply so staring at the short bit I think why not curve the bouyancy tank side slightly that would solve the problem but then I thought why not rebate the cleat while I'm at it. Pic4 shows the glue up I have had to do it in 3 stages to get all the bits to stay in place.

Onwards today I got to 3D pic5. Bewdy.

I'll continue to explain some other mods I'm doing just to make life a little more difficult but thats part of the fun I recon.

BTW I have decided on a name "A Ducks Transom" as when I have finished I will have used up a Kings Ransom in Brownie points for all the shed time.

Cheers for now

Mike

Howdy Mike,

That curved top transom looks waaaay too cool! Richard, Ted, Lauren, Dean and I all had good sails!

You will probably join us one of these days.

Mik you have eye for detail despite the bad pics, I must learn how to post the pics at higher pixels or what ever you call them.

Wished I'd ventured down to West Lakes now as it looked to be perfect conditions. Oh well next time.

Hello All,
I have made a little progress it has been slow going as I play around with some mods, the pics show a couple of changes to Miks plans.

1. Finally fitting the frames after gueing a bit here and there. First problem I had was finding some decent clear lengths of oregon from my salvage pile, I ended up laminating a few pieces.

2. The #2 frame is curved and rebated for the ply a bit of mucking around but hopefully worth it. While I was experimenting I first shaped a curve that looked good then copied onto a second section glued to create the rebate.

3. After getting the front tank curve sorted I cut the rear cleat in one piece and cut the rebate with a router using the curve offcut as a fence. Cutting the angled housing for the transom cleat was a little tricky just marked the cut then eye balled it on the table saw sled using some wedges to set the angle. The challenge now will be fitting the ply

4. Centre case seems to fit OK again played with some shaped top cleats think they work.

Question: How to mark out the foil cut out, I have penciled the inside of the case and plan to drill a small hole at each corner to get the case layout on the outside then make a pattern and orientate to the drill holes. Is there an easier way?

Cheers for now
Mike

An update

Slow going lately too many projects, anyway.

First pic I've fitted frame #2 and cut the tank ply to fit added a cleat to the top edge for the deck. Cut and planed some nice straight grain oregon for the coamings and planed a rebate in them so they will cover the deck edge and screw holes for the top cleats. Next job is to glue the coamings to the deck I will screw from the underside while the glue dries and glue the tank ply in place to the curved cleats then fillet the bottom edge.

Pic 2 is the finished rudder box and tiller, fairly happy with this I used some American Red Cedar for the tiller and when ripped to width the strips took a natural curve so I just laminated without further machining.

No pic but I finished glassing the spars and foils as well.

Cheers
Mike

If you just want a rectangular hole for the foil (which I think is good enough for the PDR), the easiest way is to drill a single hole big enough for a router bearing bit, and simply rout it out!

Alternatively you can cut it by hand with a hacksaw blade, it's not too hard to follow the line of the case.

Finally, for a foil shaped board, drill a single hole on the centreline at the front and rear of the case, use a sliver of the foil as a template to mark between them and cut along the line!

Hope that gives you some ideas.

Glad to see progress!

Cheers,

P

Yep I can't do it the easy way and wanted a foil shaped hole. Thanks for the idea.

Howdy Mike,

Do you have any pic updates of what you are up to. A floor covered with centreboard shavings ...

Make sure the foil shaped slot is a little spacious. Otherwise the board will jam when it moves away from being perfectly vertical.

Also the case is longer than the Centreboard - we put a spacer down that back of the case to match the actual final board size. The spacer is a little bit of a loose fit to allow for soak/expand and held in place with a single screw at the top.

Best wishes
MIK

Hi Mik,
Not much boat building going at the moment I'm afraid as my attention has been directed to another project. It still has a slightly aquatic theme as in a stand for my daughters turtle tank.

You see our turtles can't live in just any tank like the one we already had they needed your penthouse size tank with all the trimmings. So to support this large vessel it was decided by the females in the family it needed a suitably crafted piece of furniture to reside on. As luck would have it I had some left over tassie myrtle and veneer to produce a stand worthy of said tank. Anyway tis nearly finished and I will post a pic when done.

As you can understand turtles must take precedence over ducks in our house.

Back to ducks I has been giving some thought to the jamming aspect of a shaped slot thanks for the info. If I align the rear end of the slot with the front edge of the rear centre case spacer (boy that does not write to well) then maybe a piece of rubber strip glued to the spacer for the centreboard to rest against should be OK, yes. From memory that was common practice in dagger board cases.

Hope to get back to things next week and post some pics of the progress.

Cheers
Mike

Howdy Mike - show us your turtle furniture - go ON!!! It is wood after all!

It is best to put the centreboard pushed to the front of the centrecase. Which means there will be some space behind.

So measure the width of the board from the front end of the slot.

Bit more progress this week.

Got the side decks glued along with the foredeck, had to do a bit of filing along the bow as I cut the sheet too short AGAIN

. Rough cut the mast hole and fitted the front coaming. So hull just about ready for final epoxy coat and some varnish here and there.

Decided on a hull colour "A Ducks Transom" shall be black. Yep I know it will show every bump and hollow and black is not a good colour over epoxy but black it will be.

Wet sanded the foils ready for the final pox coat the spars are ready for varnish

Did I mention Shorty sent me the hull # ..........220

Mike

Boatmik · #14 9th Jun 2008, 11:45 PM

Oh Well - at least I will know where you are with the ouch ouch ouch when you sit down after each tack!

Seriously though ... it is looking rather nice! With a black hull the varnish will look stunning!!!

.......um still need to do some rounding there and I'm not quite happy with the curve on the transom think I'll flatten that a little.

Thanks Mik I've been playing with a slightly modified logo too.
