Many thanks for the replies and 'likes'. Juraj, your comments regarding the full size William are very interesting. This is my first attempt though and I will be building the kit 'straight out the box' as I think this will give me the best chance of actually finishing!
I stumbled across the Model Boats magzine after searching Gunboat William on Ebay. The article is much more than a review, more like a build log with plenty of pictures. It will be very useful.
The first part of the build was straight forward, sanding the bearding line, assembling the keel pieces and adjusting the bulkheads for a nice fit on the keel. A little sub-assembly on the rearmost bulkhead was completed and the bulkheads glued in with Titebond.
After fairing the bulkheads and adding filler blocks at the bow a start was made on the first planking. Laying the first plank took took a lot of deliberation and experimentation! The planking tutorials on here suggest to start planking from the keel, the kit instructions say start at the top and work down the hull to the keel. I opted to follow the instructions and after lots of messing about with different types of pins, small hammers, pin pushers (which I did not get on with at all) different size pilot holes etc. etc. I finally got the first planks laid either side of the hull. This, after adding a batten each side to stiffen the whole thing up.
I will add more shortly.
Cheers, Jack
