Harry's IOM sails are now rigged and they aren't too bad. There is definitely room for some refinements to improve their shape but I'll play around for a little while before jumping into the next suit. I should also make sure that the next sails are legal and the sail numbers are correctly positioned. I was so keen to use my home made stencil I put the first number in the wrong location. I noticed my error almost at once but it was to late the pen had streaked it's black inky mark on the film so there was nothing I could do but complete the task somewhat gutted.
Still looking on the bright side the Hurricane is coming along nicely

I have finished making my first suits of sails both for Rebel a RG 65 and also a suit for Harry's IOM, Bor. Now we just have to wait till Sunday to see how Harry's new sails perform. Between now and then I just have to stencil in the sail numbers and fit them to the spars.
At the same time I have also been doing a bit to the Hurricane fuse including the upper decking, cockpit, cowl and wing tips.

Rebel's balsa core hull has been laminated with 1 layer of 80g/m2 fibre glass. I'm hoping this will be adequate and offer enough impact resistance. The internal surface of the hull will also be laminated around the high load areas of the fin box and mast.
I have also made my first suit of sails which in the whole was an enjoyable job. However, the mylar film sets in a better shape on one tack better than the other so perhaps I'll be making another suit pretty soon. This evening I've drawn out a new IOM main for my sons yacht and will turn the film over on each alternate panel to try and stabilise the shape. I can't be too fussy as I bought over 20m of 50 micron film for just over 8.00 inc p&p on eBay on Christmas Day! Unfortunately, it's not double matt sided so one side has a very glossy finish but I doubt this will have a major effect on actual performance.

Yep, here we have two poseurs showing off their 3D gliders. A brightly coloured Vagabond and a slightly more subtle (plain Jane) Traceur. Due to the pretty windy conditions and a couple of test crashes they were grounded during this slope session.

The 66" Pegasus Hawker Hurricane kit was taken off the "To Do" shelf the other day, opened and work has started in ernest. I wanted to push on with the wings so I could reinforce the wing joint at the same time as laminating the Rebel RG 65 project. The fuse is also making steady progress but a little less messy.
I carefully remove the veneer put aside for re-use and dust off my trusty Bosh to router out the wing servo apertures. Then using an old tent pole I carefully drill the conduit for the servo cable. Following that I used the same technique to recess the
Flap servo.

Rebel has been planked and faired. Those curves are all man and hand made without any form of software intervention or Can't Frigging Design ( CFD) assistance.

It's such a shame to see these once lovingly constructed, pristine models being left to rot. There's a Catalina, Leopard Moth, A4 Dutton perhaps a DH Vampire and Sunderland.
If you are of a sensitive disposition you'd better look away, what you are about to witness could be very disturbing.

The photo's below were taken just a couple of miles from my house. The 1951 National Championships at Fairwood Common Aerodrome. Awards being presented by Lady Whitten Brown. Wife of the then deceased Sir Arthur Whitten Brown the first man to fly across the Atlantic non stop in 1919. Photo's include Mignet's own Flying Flea, a Model of a Gypsy Moth which flew from Britain to Australian in 1934, Leopard Moth, Slinsgsby Grasshopper or similar and members of the Swansea Aeromodellers Club....Continue Reading

This part of the build has got to be one of the most rewarding. With each plank the hull shape develops in front of you and you cant help but start imagining the completed model effortlessly gliding through the water.
The majority of the planking to the freeboard has been cut to taper from 5mm at the stern to10mm at the bow. Even though this design is slab sided and the freeboard could have been cut from a single sheet I chose to plank it due to the additional stiffness laminating achieves and also to reduce the likelihood of twisting by the alternate turning of each plank end to end. It's how they made the old wooden spars in the old days to stay relatively straight and strong.
When it comes to cutting the normal planks I cut the individual strips using two lengths of alloy angle, one placed on top of the other. It's quick and accurate.

Yesterday I visited a friend to look at a pond yacht he had inherited. Specifically he wanted ideas and help to make a new rig and sails as the originals were long gone.
After a little searching I believe 'Endeavour' is an early (1929) 36R . I have come to this conclusion due to her size:
Length 35" Beam 11" Draft 7" weight roughly 11lbs. These measurements fit the 36 Restricted Class perfectly.
Now it's up to the new owner to decide exactly how far he wants to go with the refurbishment, but if it was up to me I would strip the existing finishes right back and complete the painting and fine coach work back to the original. Re-rig and have new traditional clothed sails made by Frank Nylet. Then go and show her off in the best arena possible, a Victorian built boating lake. Although, the nearest one is 50 miles away at the Knave in Barry, South Wales.

Not sure if I've mentioned this is in an earlier post but in this case I don't mind repeating myself.
I love 5mm thick foam board! There you go I've said it
A scalpel slices through the straight cuts and the scroll saw makes light work of the curves. Yellow paper templates stuck with Pritt on to the white board helps to show you exactly where to cut. Pins have a fair hold just in the foam but for a better grip it's better to pin at angle to pierce the paper as well.
Next job is to strip down some sheets of balsa into 3,5 and 10mm widths.

When my head hit the pillow last night and my imagination kicked into the usual modelling hyper drive a cantilevered sail control arm flashed into my minds eye. All of a sudden I could see how a normal length servo arm might provide enough sheet travel for my latest Rebel RG65 project.
This evening I set about knocking up a crude experiment just to see if my idea had any legs and I was quite impressed. A normal servo arm radius of 25mm provided 100mm of sheet travel. Another advantage is the torque isn't jeopardised and it's also relatively light. All together a win, win idea perhaps.
The first photo shows a standard futaba 3001 servo in the sheeted in position and in the second photo the servo is in the sheeted out position. The geometry can be improved slightly to further reduce the holding torque required whilst in the sheeted in position.

Today at the lake three of my design and builds were competing. The wind was very light and kept us guessing which direction it would come from next but that was nothing compared to the course. For some unknown reason it was set back to front with the only beat from the gybe to the leeward mark and it wasn't impossible to complete a lap without a single tack.
Besides that it was a good feeling to watch my handy work being raced and enjoyed.

I have transposed the shearline, chine, rocker and beam dimensions at 14 stations to provide the shadow templates.
It may make look tricky in the photo's but please take a little time to understand how beautifully simplistic this method is to form the most natural curve from the chine to the rocker hull centreline. It really is amazingly simple.
photo 1
Draw the shape given the width of the deck/shearline. The depth from the shearline to the Chine and the width of the chine/beam. These measurements are taken off the hull section and deck/hull plan.
photo 2
On another piece of paper mark the centre line and chine
photo 3
Turn the paper 90 degrees, place the Chine mark on the rocker point and mark the intersection of the chine and centre line
photo 4
Turn the paper back to the original position. Then keeping the centreline mark on the centreline and chine mark on the chine line turn the paper a couple of degrees and mark the spot.
photo 5
Turn the paper again, check the centrelines and chine lines are still correspond and mark the spot
photo 6
Repeat this process until the edge of the paper reaches the centreline
photo 7
What a fantastic way to produce any ellipse shape
photo 8
Now I'm in a position to cut each one out. When it comes to cutting the curve I fold the template in half.

The brain has been working overtime recently so it was about time I sharpened the pencil and started to put some lines down. I thought this might help take my mind off the RG65 design/build project but alas not, I've been truly brainwashed. The only cure now is to just get on with it.
So, The length of 65cm is a given. I have opted for a fairly narrow 9cm beam a 5.5cm transom and a max rocker of 3.7cm. Not sure what the draft will be as I haven't cast the bulb.
Below is the very basic hull section and deck/hull plan. Not too much detail as yet but this drawing will be tweaked and develop into a true working drawing encompassing some of my own ideas.
Given the info above (LWL, beam, rocker and shear line) I can now form the shadow section drawings.

Not long ago Doug just had one of those days! It didn't matter what he did something 'rotten wood' happen!!

And earlier in the racing calendar I ventured to a District Event at Woodsprings and wasn't that impressed!!
