Help! Got to attach the brackets on the rudder of the pavel nikitin san bartolome. The pictures in the build manual are a bit vague. Has anybody got any pictures or advice many thanks. Also on the stern of the ship there is a stage that goes around the ship the sides come in 4 pieces unsure on how they go together again the pictures in the manual are vague TIA.

We are here to help but really need some photos of the manual and the parts. Attached is a photo that I found online that looks like the model in question. Fair winds!

Not sure what brackets you mentioned, but IF you are talking about the rudder hinges, from the build log Kurt mentions, the pintles and gudgeons look to be as in the drawing below. The dimensions are for another ship so go with what your plans indicate, Obviously there is more detail than what is needed at small scales, but hopefully will be a little help.

Having the triangular pieces for the gudgeons and pintles is really a great idea. I am pretty sure the strap should follow the bend as below. If it is as you show it the rudder cannot turn as it will be flush with the stern post, defeating the purpose of the triangular shape.

I'm not to sure what you mean not your fault it's me I'm not the sharpest tool in the box. Do you think the triangle piece on the bracket that attaches to the stern post should be bent so they face towards the rudder triangle piece if that makes sense
 
They need to be bent to follow along the triangle piece. I added another sketch at the bottom of the second picture below that may be more clear. The stern post and the forward edge of the rudder were bearded otherwise there would be no way the rudder could turn.

Thanks Allan it does make more sense. I never made a rudder with the triangle inserts before I think I got to involved with the triangles and it blown my mind once again thank you for time.

I believe that Allan has this right. The question to be answered has to do with the sizes of the triangles. There are 5 pieces with big triangles and 5 with small triangles. Which are the pintles and which are the gudgeons? Also, should the pintles have pieces of brass rod soldered in the holes to make them real pintles? Fair winds!
 
Thinking about the small triangle will have to go on the rudder because I don't think the legs will be long enough to attach to the stern

That is odd. I have no contemporary information on Spanish ships, but on British ships usually there are a number of pairs of gudgeons and pintles and each pair has the same width as the thickness of the stern post and rudder where they are put in place. But, every pair is a different width as they need to match the breadth of the stern post which tapers as does the rudder and can be seen in the first drawing in post #8 which is from page 130 of Goodwin's Construction and Fitting book. For example, for the British 80 gun ship Cumberland of the 17th century, (long after San Bartolome so only to give an idea on this taper) the breadth at the head was 24 inches and tapered to 16 inches at the bottom to match the width of the keel. Again, maybe the Bartolome was built differently. Might be a good question for the curator staff at the Museo Naval in Madrid :)

Very informative Allan. Not to sure how close to the orignal Pavel Nikitin has designed this model. Either way this is what makes building these ships interesting
