Hi mpg5

I am afraid I can be of little help other than recommending:

The quality of wooden blocks (pouilies, en Francais) has always been quite variable.

The bindings may be galvanised steel, stainless steel or bronze.

The sheaves may be iron, bronze, stainless steel, nylon, tufnol or lignum vitae, with or without roller bearings and the roller bearings may or may not be in cages.

The shells may be made of ash, elm or, for some bizarre reason, teak (a wholly unsuitable wood for the job!)

Unfortunately without actually examining different blocks it can be hard to tell what the quality is like.

Having said all that - it may well be possible to repair broken wooden blocks - it usually is - they are very simple things.

If the blocks are used on sheets they need to run very freely, but are not under heavy loads for long. If they are used on halyards then they are under heavy load for longer. Therefore, roller bearings are of more benefit on sheets.

Look at the other blocks on the boat and try to match them. You speak of 12 mm and I take it this is the diameter of the rope. It is very advantageous to have blocks that are larger than the minimum size for the rope. An old rule for sizing blocks was that the length over the shell should be at least three times the circumference of the rope, i.e. for 12mm diameter rope the block should have a shell 120mm long as a minimum.

Nantaise de Poulies has a good reputation and if you are in France I would start there. Toplicht and Classic Marine are also both good.

Hope this helps.

I make my own traditional blocks out of offcuts from fencing posts, made-up wire strops, and sheeves out of scrap sash windows.
