bear Posted November 13, 2015 Share #1 Posted November 13, 2015 Ahoy Mates What type of joint should be used or types for 90 deg. corners of top railings along the hull . Would it be a butt joint or should you have a tongue or other type of interlocking shape? Time period would be 1600-1750 English warships.

Jaager Posted November 14, 2015 Share #2 Posted November 14, 2015 My first thought was snarky- especially for the English shipwrights: Why do a simple butt joint when you can do a scarph? Then thinking about it - the structure is subject to constant motion and stress in all 4 dimensions - though the effect of Time is much more gradual. A straight butt joint would be difficult to fasten in a way that was not subject to early failure. Quick research answer: Not a butt joint or a scarph - a third element : a lateral knee was worked in. It spanned about 1/2 the width of the rail timbers, each arm would be long enough to support a couple of horizontal trunnels into each rail segment and the inner surface would be an arc rather than an abrupt meeting of two planes. mtaylor, Canute and dgbot 3 Quote NRG member 50 years Current: NMS HMS Ajax 1767 - 74-gun 3rd rate - 1:192 POF exploration - works but too intense -no margin for error HMS Centurion 1732 - 60-gun 4th rate - POF Navall Timber framing HMS Beagle 1831 refiit 10-gun brig with a small mizzen - POF Navall (ish) Timber framing The U.S. Ex.
