Excellent progress.  We look forward to watching these joints come together, step by careful step.  IMO, they can make or break a model.

 

You are several months ahead of my latest project.  The mobile shipyard is still working on frames.  We did have a friend deliver a package of pearwood stock to our current campground, for the keel and rising wood.

 

So, workers here are already planning the steps and process for laying the keel and stem/stern pieces.  I will continue to follow closely to glean what I can from your techniques and experience! Thanks for the great pictures and process descriptions!

And I will be doing the same. Safe travels!

Here's the result of this week's work:

I felt that if I worked these joints anymore, the result would start to degrade; hence the decision to attach and move on to another piece.

 

 

Question: Is it wise to shape the cutwater at this point (and set it aside for a really long time)?

[Greg Davis]

I decided to start work on the cutwater. Templates for all the parts were rubber cemented a sheet of Swiss pear and cut out with the scroll saw - some closer to the lines than others depending on the size / complexity of the parts. This is my first opportunity to fabricate a built-up cutwater and I am looking forward to the experience. Of course the situation leaves me with some questions as how to proceed. Here's the current plan:

 

I've numbered the parts in a perhaps strange order - parts 4 and 5 are numbered in the plans, but the rest are not, so I chose a numbering system that seemed reasonable but would not mirror the intended order of assembly. 

 

1. Fay parts 1 and 2

2. Smooth top and bottom contours of the assembly

3. Fit and add part 6 (remembering to have shaped the top S-curve of 6 beforehand) 

4. Form and add parts 3, 4, and 5.

5. Begin matching this assembly (parts 1-6) to the stem.

6. Match the inner side of 7 to the stem

7. Cut the scarf joints on 6 and 7

8. Connect 7 to the 1-6 assembly.

9. Continue shaping the joint between this unit and the stem

10. Add the forefoot to the stem assembly and insure the cutwater matches well with the stem and the joint between part 7 and the forefoot.

11. Set the cutwater in a safe place and have a nice glass of scotch and/or whiskey!

 

Tapering of the cutwater, etc. can then be done at a later date.

 

Please let me know if I am missing something important here.

 

So here are the cutout parts and a start of forming the joint between parts 1 and 2.

[BradNSW]

Look forward to seeing the results of the steps you outlined above.  I'm sure you will nail it...slow and steady! 

 

The joints in your previous post look nice and tight.  

 

Can't wait to see them with your finishing treatment.  That should really make the wood grain pop and accentuate that great joinery!

Looking good so far. The upper part of the assembly is known as the knee of the head with your parts 4 and 5 the standard and hair bracket.

Thank you for the proper vocabulary!

By my first try's I glued the Knee of the Head directly to the stem. But in the meantime I think it is much better to do this after building the complete farming of the hull. What you should prepare now is a hole in the stem and the knee that makes it easier to adjust and center the parts later.

I would agree with Christian. It's also much easier to apply planking at the bow without the knee in the way.

I will definitively be string the structure in a safe place after building it and then attach the cutwater / head once the hull has been planked.

 

Thanks for the input / direction!
