My long time restoration of SX-2 is continuing albeit slowly.
For those not familiar with this vessel it is a 22ft varnished marine ply Express Cruiser built by Nock and Kirby (the famous Sydney hardware dept.store) in 1961. 48 yrs old!
She is powered by twin 70 hp  1982 Johnson outboards. Originally two 75 hp  1960 s.

That looks to be a fairly recent pic Neil.
Are you that far advanced?

My first project was to replace the widscreens. New molded Perspex was too expensive so I took the existing screens to a company in Granville (Sydney).

They are of the curved type ,1950 s American auto style but split centres.
The makers carefully marked out the slope and curve onto flat polycarbonate .
Brand name is 'Cyrolon' but comes in many names such as 'Lexan'.
Two weeks later I picked up four pieces of flat plastic that looked like nothing on earth.
However this material is extraordinary and once physically bent into place looks like the pics.
I was able to fix all four panels (unaided and lonely,without heat treatment.Just willpower and luck.
This was over four years ago but the cost then for all of it was under $400.

Also got them to cut number plate covers of the same material for $20 .They are tow bar proof.
Boat is hiding at the back with a refurbished nose!

Another shot of the top screen giving an idea as to how it is fixed to the centre post and frame.

I wish Guy,
If it were current you and Mercmum would be in the pic !

Taken at Sussex Inlet abt  4 yrs ago but gives good aspects of the craft and the stains in evidence.

Starting with the screen post I will report in sequence over a period of time as to what has been done .
If any new viewers want to ask anything on timber boat  work that may relate to SX-2 by all means can do now.
Next post : The pointy end .

Stage  2
Replacing the stem (bow) and surrounding panels.
The original stem was made up of four layers of 3/4 inch plywood, cut to shape (curve an bevel) then laminated together to the timber down to the keel.
As water got into the top,being ply,the cells drew moisture down and the rot was not discovered,due to the varnish and paint until it was too late (as usual)
Drastic action- Circular saw set to the depth of the ply and cut up both sides and across th deck.
Thes cuts were made  over the frame timbers at half width so that new sheets could be attached.
The base of the stem was cut, chiselled and shaped to take new timber and maximise holding power with s/s screws and epoxy glues.
Bote- cote (Aus) and West-system (Amer) are the most popular two packs.
The replacement timber used was from an old  launch engine bed .Light strong and a pleasure to work. Probably white beech  (can't get it anymore )with a wonderful molasses smell .
It was bevelled and shaped from the remnants of the old stem fixed with s/s screws and epoxy with a stainless angle barscrewed to it and boltedwith the two mooring/winch eyebolts for extra strength.The replacement panelswere then cut andscrewed/glued into position on the half frame timbers.
The main problem with these small plywood panels is that they lose their natural curve. The originalfull panels could be more easily curved (tortured) to give the correct effect. To give the bow it's shape I've had to fill/sand so many times over six months to build up to suit the eye
Treatment of the deck piece was a problem due to the straight cut/join.
An extra piece of  3mm ply was shaped and placed over the join .

This rounding effect takes the lines of the boat overall.
As I will show later some of the mid/stern deck has been replaced and this also will be covered by these cut outs. They are about 16 ft long to put them into perspective.
Bow fromt he front.
Next time:
Transom replacement Grrrrrrrrr!

Appendage to first two posts:
1) Photo p1010210 - the striping on the foredeck is made up of strips of masking tape.
This is experimental to see  the visual effect. What is proposed is to cut  5 mm strips of 3M (Minnesota Mining and Manufacturing )  Wink adhevise non slip tape .
a) It will look like inlaid wood strip.
b) It will avoid slipping on deck and getting caught between the (toes)  Angry or going overboard.

2) It is imperative when using marine ply,no matter what the quality,that  it must be completely encapsulated.That is sealed with paint,varnish ,epoxy etc .particularly the end and edges to prevent moisture entering.

3) The bow having been filled and faired will not allow my original timber finish however some major marine paint manufacturers will tint their polyurethane to suit so I will endeavour to obtain my colours of jarrah and teak.

Here is a part of the restoration that I imagine most boaties would like in their craft.
I don't know if it is unique but it certainly gives more room when required .
The photo is of one of the two seats/stands that are being refurbished .
It is taken from bottom up (my late Airedale Terrier is underneath helping ) and you can see two small blocks of wood .
By quickly removing one block the curved vertical support swings away 90 degrees to be flush with the hull and then the (padded ) seat drops 90 degrees both with the  aid of brass hinges .  Cool.
