Now the fun begins.

I decided on leaving the motor base plates for now as they also need to be coated with resin before being epoxied into place.
It was time to think about the Transom Flap construction and attachment to hull. My end conclusion was to build as close as possible to original setup as this was relatively easy to do (refer to earlier photo/post showing props and shafts).

The flap was constructed of all plywood using 3mm ply for the main base/sides and 1.5mm ply for webbing etc. As this flap will take some beating, I added small amounts of epoxy to all joints. A length of 3mm brass tubing was epoxied into place and after epoxy had set, the tubing was cut and filed to allow fitment of 4 hinges. The hinges were made from 2mm brass flat cut out using a Dremel tool and filed to correct profile. A 3mm hole was then drilled into each hinge to allow a 3mm solid brass rod to pass through them.

Next step was to manufacture the 2 linkage couplings that are fitted to the transom flap as per Bluebird's drawing in post #96 (item "A").
For this I decided to use a "T" section of Aluminium as I could not find anything suitable in Brass. Here I had cut off 2 sections 8mm wide and trimmed down to size. I then drilled a small hole in each for the linkage to move freely and epoxied into place.

With the transom flap assembly complete, it was time to mount and set into the transom.
As per the original setup, I needed to fit an angle piece of material at the base of the hull and against the transom. Here I used a length of 1.4mm aluminium angle of which the bottom side had to be narrowed down - to allow transom flap movement.

I then marked and drilled 4 slots into the transom for the flap hinges then filed to allow hinges to pass through at a 45 degree angle. The Aluminium angle also had to have 4 slots filed for the hinges and then epoxied into place.

Once I was happy with the setup, the transom flap hinges were fed through the transom and a small amount of epoxy used to hold into place.
With the transom flap removed I then placed P38 around the hinges which I made to protrude the transom by 10mm. When the P38 had set, I refitted the flap and checked for operational integrity (aviation lingo) O0

The last job to do with the transom flap was to fit another length of Aluminium angle above the flap. The angle also needed 4 slots filed to allow for the hinges to pass through. After this had been achieved, the angle was fitted into place and flap checked for free up and down movement before being epoxied into place.
The transom flap was reinstalled and found that the flap could move 15 degrees up and 15 degrees down without interference - ample as I only require about 5 degrees either way. O0 O0 O0

Martin No.1 mentioned a valid point - I need to now and again add something into the photo's to show relative scale - good point O0

Hope the One Pound Note is still valid - got it in the early 70's.

Before I start with the linkages through the transom, I thought that I may start on the transom shelf and when finished and glued into place, then start on linkages.

The shelf and flap epoxy joins will be cleaned up with Dremel tool including wet and dry. before painting which I hope to do this weekend.

Picture of transom shelf construction (early stage) with references added ;) ;)

Hi Martin - Glad to see that the note meets with your approval.

The motors will be 3 (now this is a mouth full) Darke Horse Speed 700, 3:1 Ratio Planetary extra High Performance Low Inertia Marine power units running on 20 cells each ( that's a lot of batteries) about 24Volts, running time 40 minutes minimum at medium to high revs. ::) ::) ::)

On the weekend, I'll sit the 3 motors in place with the One Pound Note for reference. O0

Just a little aside - I think that one pound notes are, probably now, collectors' items so treat it gently Martin du.  :)  Like the build - very good, very interesting  O0.

Hi Martin DU
Just spent a very enjoyable hour and a half reading through your build, it's fantastic, it really is. :)
I especially like the scale size.

Hi Martin 13,

The British 1 pound coin is roughly the diameter of our $2 coin, but thicker, and the same colour.

Are you fixing the bearings as in picture with the bush flange forward   BB P10110126 ?

Proteus
 


Proteus,

The gentleman that supplied me the motors plus the flanged bushes contacted me today after viewing the build and your comments.

You are correct O0        I'm wrong >>:-(

The flanged bush must be fitted the other way around - that is, the flange must be behind the prop..

Thanks for your keen eye and comments - most appreciated

GaryM,

Glad to hear that you are enjoying the build. Don't know if anybody has built a 6 foot (1800mm) model of BB before - everything has to be scratch built. Hope I can keep you entertained in the future and thanks for your kind comments.

Derek,
Thanks for the comments and hope that you keep watching this space. I'll look after the rest of the One Pound Notes.

Peter,
Must send you a PM and thanks for info. If I visit the money exchange booth at the airport, do you reckon I can get a One Pound Coin??. Also, do they have tinnies in the UK, possibly the same size as our XXXX or VB??? - Liquid Reference Material and throat lubrication {-) {-) {-)

Yes Martin, they do have tinnies in the UK. They're quite civilised over there actually,  :) their tinnies are bigger than ours, and you can get XXXX, Fosters or just about any brand of beer you want, in the liquor aisles of the supermarkets. Great idea  O0

CA glue tends to leave stains on timber but with a bit of rubbing down with wet and dry - looking good.
Now with a coat of primer on the shelf before carefully using epoxy to glue into place.

With the Transom Shelf firmly affixed to the transom, it's now time to start thinking about linkages connected to Transom flap through transom - work begins using Bluebird's method as posted earlier.... ;) O0
