Book Review. The Trafalgar Chronicle – 4

THE TRAFALGAR CHRONICLE

New Series 4

Edited by Peter Hore

Softcover.  £20 RRP.  Seaforth Publishing.

 

“Dedicated to Naval History in the Nelson Era”, the fourth volume in this series contains 21 essays, richly illustrated, and clearly reflecting the fact that the authors are enthusiastic, knowledgeable and articulate about their subjects.

 

This is a book to be read from cover to cover.  It has classy feel, the illustrations and maps are excellent, the topics interesting and eclectic within the period.

 

I particularly enjoyed the chapters “The Decaturs”,  “Nelson Was an Irishman”, “Russians on the Tagus”, “Captain John Perkins” (the first black officer in the Royal Navy) and “The Carronade”.  The last because this reviewer has a particular interest in carronades.  If I might take the liberty of showing a personal item….

The essay by Anthony Bruce is the best description of the history of carronades which I have read.  Particularly the descriptions of naval actions where carronades made a significant contribution.

 

I eagerly look forward to further volumes in this series.

 

More Scale Stuff

There is the 1464 Turkish bombard (black), 17 tons, 307kg granite ball;  the 1779 long naval gun off USS Constitution or HMS Victory 24lb balls; and a 32lb carronade.  All 1:10 scale.  Interesting to see them together on my kitchen table?

POLISHING TINY BRASS PARTS

My model carronade has quite a few very small metal (mostly brass) components.  They are fiddly and a bit difficult to hold while finishing (filing and sanding and polishing).

So I bought a tumbler which is designed for polishing metal jewelry and gemstones, and gave it a go.

It cost just under $300, including a kilo of stainless steel bits, and some polishing compound.  It is designed to run for weeks at a time when polishing rocks, but I find that 30-90 minutes is enough for my brass parts.

The drum will hold 4lbs of parts.  Shown here are the stainless steel polishing bits.  The drum revolves quite slowly, about 30rpm.  Water is added so that the drum is just under 1/2 full.

after 30 minutes.  It could use another 30-60 minutes of tumbling.  Not all of these bits are for the carronade.

This is the sight for the carronade.  Complex and tiny and has sharp edges.  Ideal for the tumbler.  The CNC program diagram on the screen.

I am still experimenting with the tumbler.  So far I have used only the stainless steel shapes to do the polishing.  I will try some abrasive compounds soon.  Garnet dust seems to be the commonest abrasive.
